Highlights
• Education has a positive influence on intelligence.
• The marginal cognitive benefit of education does not reach a plateau until 17 years of education.
• Individuals with low childhood intelligence derive the largest benefit from education.
• Findings of relatively small cognitive benefits might be explained by selection bias.
Abstract: Education has been found to have a positive influence on intelligence, but to be able to inform policy, it is important to analyse whether the observed association depends on the educational duration and intelligence prior to variations in educational attainment. Therefore, a longitudinal cohort study was conducted of all members of the Metropolit 1953 Danish Male Birth Cohort who were intelligence tested at age 12 and appeared before the Danish draft boards (N = 7389). A subpopulation also participated in the Copenhagen Aging and Midlife Biobank (N = 1901). The associations of educational attainment with intelligence in young adulthood and midlife were estimated by use of general linear regression with adjustment for intelligence test score at age 12 and family socioeconomic position. Results showed a positive association of educational attainment with intelligence test scores in both young adulthood and midlife after prior intelligence had been taken into account. The marginal cognitive benefits depended on the educational duration but did not reach a plateau until 17 years. Further, intelligence test score at age 12 was found to modify the association, suggesting that individuals with low intelligence in childhood derive the largest benefit from education. Comparing the strength of the association observed among participants and non-participants in our midlife study, we showed that selection due to loss to follow-up might bias the investigated association towards the null. This might explain previous studies' findings of relatively small cognitive benefits. In conclusion, education seems to constitute a promising method for raising intelligence, especially among the least advantaged individuals.
4.2. Comparison with the existing literature
The finding of a positive association between educational attainment
and intelligence test scores after prior intelligence has been taken
into account is consistent with extant literature (Clouston et al., 2012;
Falch & Massih, 2011; Ritchie, Bates, Der, Starr, & Deary, 2013), including
a recent meta-analysis (Ritchie & Tucker-Drob, 2018). More
specifically, our results suggested an average increase in intelligence
test score of 4.3 IQ points per year of education in young adulthood and
1.3 IQ points per year of education in midlife. The effect estimate in
young adulthood is considerably higher than the effect estimate of 1.2
IQ points (95% confidence interval: 0.8, 1.6) reported in the metaanalysis
for the control prior intelligence design. However, in a simultaneous
multiple-moderator analysis, the authors report an adjusted
effect estimate of 2.1 IQ points (95% confidence interval: 0.8, 3.4),
taking into account the possible influence of age at early test, age at
outcome test, outcome test category, and male-only studies. Besides
these possible moderators, contextual factors might also account for the
contrasting findings between our study and the seven studies included
in the meta-analysis. However, it is important to notice that our effect
estimate in midlife is consistent with the findings of the meta-analysis,
suggesting that sample selectivity might have influenced the association
observed in midlife in our study and perhaps the associations observed
in the cohort studies included in the meta-analysis as well. This is
supported by findings of higher educational attainment among the individuals
in our study population who participated in the midlife study,
higher IQ at age 12 (IQ mean: 103.2 vs. 98.9) as well as our finding of
effect measure modification. If both educational attainment and intelligence
are positively associated with participation in studies and
individuals with low intelligence in childhood derive the largest benefit
from education, selection will bias the investigated associations towards
the null. This is probably the reason why the study with the least
selected sample in the meta-analysis is the one reporting the largest
effect estimate (Falch & Massih, 2011). Based on a male population who
were initially intelligence tested in school at age 10 and later at the
mandatory military draft board examination at age 20, the authors
found an increase in intelligence test score of 3.5 IQ points per year of
education (95% confidence interval: 3.0, 3.9), which is much more in
line with our results.
Our finding of a stronger association between educational attainment
and intelligence test scores in young adulthood compared with
midlife in the subpopulation of individuals who participated in both
examinations is consistent with the findings of the meta-analysis
(Ritchie & Tucker-Drob, 2018). One possible explanation for this
finding might be that schooling has a larger influence on intelligence
compared with vocational education or training, which mainly takes
place after the age of 18. However, the finding might also be explained
by the smaller time gap between the measurements of educational attainment
and intelligence, as the measurement of educational attainment
in midlife in most cases will reflect one's educational attainment
before the age of 30. The older the age at outcome testing, the larger the
time gap and thus more additional factors might influence the association,
such as the individual's occupational complexity and health
(Smart, Gow, & Deary, 2014; Waldstein, 2000).
In general, our finding of a positive association between educational
attainment and intelligence test scores should be interpreted with
caution. As previously written, it is difficult to separate the positive
influence of educational attainment on intelligence from the influence
of selection by prior intelligence, whereby individuals with higher intelligence
test scores prior to variations in educational attainment
progress further in the educational system. Although our results show a
strong positive association between educational attainment and intelligence
test scores after prior intelligence has been taken into account,
a hierarchical analysis of our data suggests that educational attainment
only increases the amount of explained variance in later IQ by
7% when IQ at age 12 is already accounted for (R2 = 0.46 vs
R2 = 0.53; p < .001). Therefore, our findings most likely not only
reflect the positive influence of educational attainment on intelligence,
but also a residual influence of selection processes which our statistical
analyses were not able to take into account.
To answer one of our specific aims, we also investigated whether the
increase in intelligence test score for each extra year of education depended
on the educational duration. Irrespective of whether intelligence
was measured in young adulthood or midlife, intelligence test
scores were found to increase with increasing years of education in a
cubic relation, suggesting that the increase in intelligence test score for
each extra year of education diminishes with increasing length of
education. This finding supports the hypothesis proposed by the authors
of a recent study, who, based on their own data and the existing literature,
suggest that the influence of educational attainment on intelligence
eventually might reach a plateau (Kremen et al., 2019).
However, where the authors of the previous study suggest that this
plateau might already be reached by late adolescence as their findings
show no significant association between educational attainment and
intelligence test score in midlife after IQ at age 20 has been taken into
account, we find no plateau until approximately 17 years of education.
In fact, replicating the previous study's statistical analyses we find an
average increase in intelligence test score in midlife of 0.8 IQ points per
year of education taking IQ at age 20 into account (Supplementary
Table 4). We speculate whether this contrasting finding might be explained
by the representativeness of the study populations as the previous
study is based on a selected sample of twins serving in the
American military at some point between 1965 and 1975. Thus, a study
based on the two Lothian birth cohorts, which like our study includes a
follow-up examination of a population-representative survey in childhood,
finds a weighted average increase in intelligence test score in late
life of 1.2 IQ points per year of education taking IQ at age 11 into
account (Ritchie et al., 2013). However, the contrasting finding might
also be explained by residual confounding due to the use of non-identical
baseline and outcome intelligence tests in our study. Nevertheless,
in our study, the strongest association between educational attainment
and intelligence in midlife was observed in upper-secondary school, i.e.
around 10–13 years of education. A possible explanation for this finding
might be that pupils up to and including upper-secondary school receive
general education, which improves exactly what the intelligence
tests included in our study most likely measure: General cognitive
ability. After upper-secondary school, individuals start to specialize in
different fields, which may explain why the increase in intelligence test
score for each extra year of education diminishes. However, the cubic
tendency was relatively weak and as written above the association
between educational attainment and intelligence did not reach a plateau
until approximately 17 years of education, corresponding to the
completion of a Master's degree program. As our study is the first to
investigate whether the increase in intelligence test score for each extra
year of education depends on the educational duration, replication of
our finding is needed – preferably in studies with access to the same
baseline and outcome test.
Finally, to answer another of our specific aims, we investigated
whether the increase in intelligence test score for each extra year of
education depended on the intelligence prior to variations in educational
attainment. The results showed that the increase in intelligence
test score for each extra year of education was higher in the group of
individuals with an IQ < 90 compared with the group of individuals
with an IQ of 90–109. Although this finding clearly needs to be replicated,
it is in line with the findings of a Danish study investigating
whether distributional changes accompanied the secular increases in
intelligence test scores among males born in 1939–1958 and
1967–1969 (Teasdale & Owen, 1989). According to the authors of that
study, a possible explanation of why individuals with low intelligence
in childhood derive the largest benefit from education is that the Danish
school system for the last seven decades mainly has focused on improving
the abilities of the least able (Teasdale & Owen, 1989).
Therefore, future studies are needed to investigate whether our finding
is peculiar to the Danish school system or whether it can be generalized
to school systems in other countries.

Self-reported ratings of deception ability were positively correlated with telling a higher frequency of white lies & exaggerations, & telling the majority of lies to colleagues, friends, & romantic partners
Verigin BL, Meijer EH, Bogaard G, Vrij A (2019) Lie prevalence, lie characteristics and strategies of self-reported good liars. PLoS ONE 14(12): e0225566. https://doi.org/10.1371/journal.pone.0225566
Abstract: Meta-analytic findings indicate that the success of unmasking a deceptive interaction relies more on the performance of the liar than on that of the lie detector. Despite this finding, the lie characteristics and strategies of deception that enable good liars to evade detection are largely unknown. We conducted a survey (n = 194) to explore the association between laypeople’s self-reported ability to deceive on the one hand, and their lie prevalence, characteristics, and deception strategies in daily life on the other. Higher self-reported ratings of deception ability were positively correlated with self-reports of telling more lies per day, telling inconsequential lies, lying to colleagues and friends, and communicating lies via face-to-face interactions. We also observed that self-reported good liars highly relied on verbal strategies of deception and they most commonly reported to i) embed their lies into truthful information, ii) keep the statement clear and simple, and iii) provide a plausible account. This study provides a starting point for future research exploring the meta-cognitions and patterns of skilled liars who may be most likely to evade detection.
Discussion
We found that self-reported good liars i) may be responsible for a disproportionate amount of lies in daily life, ii) tend to tell inconsequential lies, mostly to colleagues and friends, and generally via face-to-face interactions, and iii) highly rely on verbal strategies of deception, most commonly reporting to embed their lies into truthful information, and to keep the statement clear, simple and plausible.
Lie prevalence and characteristics
First, we replicated the finding that people lie, on average, once or twice per day, including its skewed distribution. Nearly 40% of all lies were reported by a few prolific liars. Furthermore, higher self-reported ratings of individuals’ deception ability were positively correlated with self-reports of: i) telling a greater number of lies per day, ii) telling a higher frequency of white lies and exaggerations, iii) telling the majority of lies to colleagues and friends or others such as romantic partners, and iv) telling the majority of lies via face-to-face interactions. Importantly, skewed distributions were also observed for the other lie characteristics, suggesting that it may be misleading to draw conclusions from sample means, given that this does not reflect the lying behaviours of the average person. A noteworthy finding is that prolific liars also considered themselves to be good liars.
The finding that individuals who consider themselves good liars report mostly telling inconsequential lies is somewhat surprising. This deviates from the results of a previous study, which showed that prolific liars reported telling significantly more serious lies, as well as more inconsequential lies, compared to everyday liars [15]. However, small, white lies are generally more common [18] and people who believe they can get away with such minor falsehoods may be more inclined to include them frequently in daily interactions. It is also possible that self-reported good liars in our sample had inflated perceptions of their own deception ability because they tell only trivial lies versus lies of serious consequence.
Regarding the other lie characteristics, we found a positive correlation between self-reported deception ability and telling lies to colleagues, friends and others (e.g., romantic partners). This variation suggests that good liars are perhaps less restricted in who they lie to, relative to other liars who tell more lies to casual acquaintances and strangers than to family and friends [22]. Our results also showed that good liars tended to prefer telling lies face-to-face. This fits the findings of one of the only other studies to examine characteristics of self-reported good versus poor liars, which found that self-perceived good liars most commonly lied via face-to-face interactions versus through text chat [42]. This could be a strategic decision to deceive someone to their face, since people may expect more deception via online environments [43]. As researchers continue to examine the nature of lying and to search for ways of effectively detecting deception, it is important to recognize how certain lie characteristics may influence individuals’ detectability as liars.
Deception strategies
We also isolated the lie-telling strategies of self-reported good liars. People who identified as good liars placed a higher value on verbal strategies for successfully deceiving. Additional inspection of the verbal strategies reported by good liars showed that commonly reported strategies were embedding lies into truthful information and keeping their statements clear, simple and plausible. In fact, good liars were more likely than poor liars to endorse using these strategies, as well as matching the amount and type of details in their lies to the truthful part/s of their story, and providing unverifiable details. A common theme among these strategies is the relation to truthful information. This fits with the findings of previous literature, that liars typically aim to provide as much experienced information as possible, to the extent that they do not incriminate themselves [35, 44]. Additionally, good liars used plausibility as a strategy for succeeding with their lies. This reflects the findings of the meta-analysis by Hartwig and Bond [45] that implausibility is one of the most robust correlates of deception judgements, and the results of DePaulo et al. [26] that one of the strongest cues to deception is liars’ tendency to sound less plausible than truth tellers (d = -0.23).
We also found that self-reported poor liars were more likely than good liars to rely on the avoidance strategy (i.e., being intentionally vague or avoiding mentioning certain details). Previous research suggests that this is one of the most common strategies used by guilty suspects during investigative interviews [46]. Additionally, all liars in our study expressed behavioural strategies as being important for deceiving successfully. This could be explained by the widespread misconceptions about the associations between lying and behaviour, for example that gaze aversion, increased movement or sweating are behaviours symptomatic of deception [2, 47].
There was inconsistency in our data between the responses to the qualitative strategy question and the multiple-response strategy question. Based on the qualitative strategy data it seems that Good, Neutral, and Poor liars do not differ in their use of strategies. However, robust differences emerged when we evaluated participants’ endorsement of the predetermined strategies. One explanation for this finding is the difficulty people perceive when they have to verbalize the reasons for their behavior. Ericsson and Simon [48] suggest that inconsistencies can occur especially when the question posed is too vague to elicit the appropriate information, which might have been the case in our study. Another explanation for the discrepancy in the data between the two measurement procedures is that data-driven coding is inherently susceptible to human subjectivity, error, and bias [49, 50]. Such limitations apply to a lesser extent to coding based on predetermined categories that are derived from psychological theory, an approach which has been heavily used within the deception literature [2]. In any case, future research should continue exploring the deception strategies of good liars using a variety of methodological approaches. In particular, it would be beneficial to establish more reliable techniques for measuring interviewees’ processing regarding their deception strategies. One potential idea could be to explore the effectiveness of using a series of cued questions to encourage the recall of specific aspects of interviewees’ memory or cognitive processing. Another suggestion is to combine the data-driven and theory-driven approaches, whereby the coding system is generated inductively from the data but the coders draw from the theoretical literature when identifying categories [50].
Limitations
Some methodological considerations should be addressed. First, the results of the present study are drawn from participants’ self-reports about their patterns of deception in daily life. Sources of error associated with such self-report data limit our ability to draw strong inferences from this study. However, previous research has validated the use of self-report to measure lying prevalence by correlating self-reported lying with other measures of dishonesty [17]. Moreover, self-report data may not be as untrustworthy as critics argue, and in some situations, it may be the most appropriate methodology [51]. This study was intended as an initial examination of the strategies and preferences of good liars, and surveying liars for their own perspectives provided a novel source of insight into their behaviour. A constraint to the generalizability of this research is that we did not establish the ground truth as to whether self-reported good liars are indeed skilled deceivers. Future research could attempt to extend our findings by examining deceivers’ lie frequency, characteristics, and strategies after systematically testing their lie-telling ability within a controlled laboratory setting.
Second, one of the most frequent concerns about using Amazon MTurk relates to low compensation and resulting motivation [52, 53]. We took measures to ensure that our remuneration to participants was above the fair price for comparable experiments. Importantly, data collected through MTurk produces equivalent results as data collected from online and student samples [52, 54–58]. As well, mTurk surveys have been shown to produce a representative sample of the United States population that yields results akin to those observed from more expensive survey techniques, such as telephone surveys [57]. It speaks to the validity of our data, for example, that the self-reported prevalence of lies, and the endorsement of nonverbal deception strategies, replicates previous research. Nonetheless, the results of this study could be advanced if future research i) directly replicates our survey amongst different populations, for instance university students, and ii) conceptually replicates this research by evaluating different methodological approaches for measuring deception ability (e.g., via controlled evaluation) and good liars’ strategies for deceiving (e.g., via cued recall).
Implications and future research
This study explored the deception characteristics and strategies used by self-reported good liars. Deception researchers generally agree that the most diagnostic information is found in the content of liars’ speech [59]. Content-based cues to deception, however, may be less effective for detecting good liars who rely highly on verbal strategies of deception. This could even offer an explanation for the modest effect sizes observed in the deception literature [60]. For instance, good liars in our study reported to strategically embed their lies into truthful information. This finding has potential implications for the reliability of credibility assessment tools that derive from the assumption that truth tellers’ statements are drawn from memory traces whereas liars’ statements are fabricated from imagination [61, 62]. If good liars draw on their memory of truthful previous experiences, then their statements may closely resemble those of their truth telling counterparts. Another interesting observation was that self-reported good liars were more likely than poor liars to provide unverifiable details. This fits with the findings of previous literature on the VA, which contends that liars provide information that cannot be verified to balance their goals of being perceived as cooperative and of minimizing the chances of falsification by investigators [32, 33]. A fruitful avenue of future research could be to further explore liars’ strategic inclusion of truthful information and unverifiable details. Doing so may give lie detectors an advantage for unmasking skilled liars. It would also be interesting for future research to examine how good versus poor liars are affected by certain interview techniques designed to increase the difficulty of lying such as the reverse-order technique [63].

Females are more proactive, males are more reactive: neural basis of the gender-related speed/accuracy trade-off in visuo-motor tasks
Females are more proactive, males are more reactive: neural basis of the gender-related speed/accuracy trade-off in visuo-motor tasks. V. Bianco et al. Brain Structure and Function, December 3 2019. https://link.springer.com/article/10.1007/s00429-019-01998-3
Abstract: In the present study, we investigated neural correlates associated with gender differences in a simple response task (SRT) and in a discriminative response task (DRT) by means of event-related potential (ERP) technique. 120 adults participated in the study, and, based on their sex, were divided into two groups matched for age and education level. Behavioral performance was assessed with computing response speed, accuracy rates and response consistency. Pre- and post-stimulus ERPs were analyzed and compared between groups. Results indicated that males were faster than females in all tasks, while females were more accurate and consistent than males in the more complex tasks. This different behavioral performance was associated with distinctive ERP features. In the preparation phase, males showed smaller prefrontal negativity (pN) and visual negativity (vN), interpreted as reduced cognitive preparation to stimulus occurrence and reduced reliance on sensory proactive readiness, respectively. In the post-stimulus phase, gender differences were present over occipital (P1, N1, P2 components) and prefrontal (pN1, pP1, pP2 components) areas, suggesting allocation of attentional resources at distinct stages of information processing in the two groups. Overall, the present data provide evidence in favor of a more proactive and cautious cognitive processing in females and a more reactive and fast cognitive processing in males. In addition, we confirm that (1) gender is an important variable to be considered in ERP studies on perceptual processing and decision making, and (2) the pre-stimulus component analysis can provide useful information concerning neural correlates of upcoming performance.

Conclusions
Present data suggest that in simple and complex visuo-motor tasks, males and females allocate their cortical resources in diverse ways, possibly leading to the well-documented gender-related speed/accuracy trade-off in visuo-motor per-formance. When the task is very simple, both preparatory (the BP) and reactive (the pP1, P2 and P3) cortical process-ing are enhanced in males with respect to females, leading to faster responses. When the task is more complex (implying stimulus discrimination and response selection), females’ proactive allocation of more cortical resources at both pre-frontal (pN) and sensory (vN) level, as well as several reac-tive stages after stimulus onset (the pN1, the P1, and the P3), leads to relatively slow and very accurate responses. In contrast, males allocate a reduced level of pre-stimulus sustained attention to the task (smaller pN and vN), possi-bly compensating with enhanced reactive attention at visual level processing (larger N1 and P2). Even though the neu-ral processing associated with S–R mapping (the pP2) is generally enhanced in males (for both target and non-target stimuli), signals associated to different stimulus categories are less distinguishable in males than females, as indicated by dpP2 effect, possibly facilitating female accuracy in a complex task.
Present research provides evidence that gender is an important variable to be considered in neurocognitive studies of perceptual decision making; this variable should be considered while planning experimental designs or interpreting the results because, per se, could explain the speed/accuracy trade-off in visuo-motor performance and relative differences in brain functions. In contrast, some studies excluded females from their samples or ignored gender as a factor in their findings (for review see Mendrek 2015), possibly jeopardizing their results’ interpretation.
Abstract: In the present study, we investigated neural correlates associated with gender differences in a simple response task (SRT) and in a discriminative response task (DRT) by means of event-related potential (ERP) technique. 120 adults participated in the study, and, based on their sex, were divided into two groups matched for age and education level. Behavioral performance was assessed with computing response speed, accuracy rates and response consistency. Pre- and post-stimulus ERPs were analyzed and compared between groups. Results indicated that males were faster than females in all tasks, while females were more accurate and consistent than males in the more complex tasks. This different behavioral performance was associated with distinctive ERP features. In the preparation phase, males showed smaller prefrontal negativity (pN) and visual negativity (vN), interpreted as reduced cognitive preparation to stimulus occurrence and reduced reliance on sensory proactive readiness, respectively. In the post-stimulus phase, gender differences were present over occipital (P1, N1, P2 components) and prefrontal (pN1, pP1, pP2 components) areas, suggesting allocation of attentional resources at distinct stages of information processing in the two groups. Overall, the present data provide evidence in favor of a more proactive and cautious cognitive processing in females and a more reactive and fast cognitive processing in males. In addition, we confirm that (1) gender is an important variable to be considered in ERP studies on perceptual processing and decision making, and (2) the pre-stimulus component analysis can provide useful information concerning neural correlates of upcoming performance.

Conclusions
Present data suggest that in simple and complex visuo-motor tasks, males and females allocate their cortical resources in diverse ways, possibly leading to the well-documented gender-related speed/accuracy trade-off in visuo-motor per-formance. When the task is very simple, both preparatory (the BP) and reactive (the pP1, P2 and P3) cortical process-ing are enhanced in males with respect to females, leading to faster responses. When the task is more complex (implying stimulus discrimination and response selection), females’ proactive allocation of more cortical resources at both pre-frontal (pN) and sensory (vN) level, as well as several reac-tive stages after stimulus onset (the pN1, the P1, and the P3), leads to relatively slow and very accurate responses. In contrast, males allocate a reduced level of pre-stimulus sustained attention to the task (smaller pN and vN), possi-bly compensating with enhanced reactive attention at visual level processing (larger N1 and P2). Even though the neu-ral processing associated with S–R mapping (the pP2) is generally enhanced in males (for both target and non-target stimuli), signals associated to different stimulus categories are less distinguishable in males than females, as indicated by dpP2 effect, possibly facilitating female accuracy in a complex task.

It has been shown that a gamble is judged to be more attractive when its zero outcome is designated as “losing $0” rather than “winning $0,” an instance of what we refer to as the mutable-zero effect
The framing of nothing and the psychology of choice. Marc Scholten, Daniel Read, Neil Stewart. Journal of Risk and Uncertainty, December 3 2019. https://link.springer.com/article/10.1007/s11166-019-09313-5
Abstract: Zero outcomes are inconsequential in most models of choice. However, when disclosing zero outcomes they must be designated. It has been shown that a gamble is judged to be more attractive when its zero outcome is designated as “losing $0” rather than “winning $0,” an instance of what we refer to as the mutable-zero effect. Drawing on norm theory, we argue that “losing $0” or “paying $0” evokes counterfactual losses, with which the zero outcome compares favorably (a good zero), and thus acquires positive value, whereas “winning $0” or “receiving $0” evokes counterfactual gains, with which the zero outcome compares unfavorably (a bad zero), and thus acquires negative value. Moreover, we propose that the acquired value of zero outcomes operates just as the intrinsic value of nonzero outcomes in the course of decision making. We derive testable implications from prospect theory for mutable-zero effects in risky choice, and from the double-entry mental accounting model for mutable-zero effects in intertemporal choice. The testable implications are consistently confirmed. We conclude that prevalent theories of choice can explain how decisions are influenced by mutable zeroes, on the shared understanding that nothing can have value, just like everything else.

4 General discussion
The valence of a zero event depends on its “irrelevant” description: It “feels better” to
lose or pay nothing than to win or receive nothing. A negative wording (lose, pay) sets
up a norm of negative events, with which the zero event compares favorably, while a
positive wording (win, receive) sets up a norm of positive events, with which the zero
event compares unfavorably, so that a negative wording acquires a more positive tone
than a positive wording. Descriptive invariance requires from us that this should not
affect our decisions, but we have shown that it does, among a fair number of us at least.
To others among us, the framing of zero events may actually be irrelevant. The
mutable-zero effect is indeed small; yet, it is a reliable phenomenon. And if one thinks
of the alternative descriptions of a zero outcome as a minimal manipulation, the small
effect may actually be considered quite impressive (Prentice and Miller 1992).
Descriptive invariance, along with dominance, is an essential condition of rational
choice (Tversky and Kahneman 1986), and it has seen a number of violations,
commonly referred to as framing effects. A stylized example of framing is the adage
that optimists see a glass of wine as half full, while pessimists see it as half empty. And
if the wine glass is half full, and therefore half empty, then these are complementary
descriptions of the same state of the world, so that, normatively, using one or the other
should not matter for judgment and choice (Mandel 2001)—but it does.
4.1 Counterfactuals versus expectations
Life often confronts us with zero events. A bookstore may offer us “free shipping.” Our
employermay grant us “no bonus.”We are pleased to pay $0 to the bookstore, and this may be
because we expected to pay something but did not.We are not pleased to receive $0 from our
employer, and this may be because we expected to receive something but did not (Rick and
Loewenstein 2008). In norm theory, Kahneman and Miller (1986) suggested that reasoning
may not only flow forward, “from anticipation and hypothesis to confirmation or revision,” but
also backward, “from the experience to what it reminds us of or makes us think about” (p.
137). In the latter case, “objects or events generate their own norms by retrieval of similar
experiences stored in memory or by construction of counterfactual alternatives” (p. 136). Thus,
“free shipping” may sound pleasant because it reminds us of occasions on which we were
charged shipping fees, and “no bonus” may sound unpleasant because it reminds us of
occasions on which we were granted bonuses; not so much because we expected to pay or
receive something. Of course, both norms and expectations may influence our feelings, and
may be difficult to disentangle in many real-life situations. Kahneman and Miller’s (1986)
intention with norm theory was “not to deny the existence of anticipation and expectation but
to encourage the consideration of alternative accounts for some of the observations that are
routinely explained in terms of forward processing” (p. 137, emphasis added). Our intention
was to compile a set of observations that cannot reasonably be explained in terms of forward
processing, which therefore constitute the clearest exposure of norms.
4.2 Expectations in decision theory
We have incorporated counterfactuals into theories of choice, so as to predict the effects
of mutable zeroes when people face risk and when people face time. Traditionally,
decision theory has ignored counterfactuals, but expectations play a role in most
theories of decision under risk. While prospect theory sacrifices the expectation
principle from EU, by assigning a decision weight w(p) to probability p of an outcome
occurring, other formulations have maintained the expectation principle but modified
the utility function. For instance, the utility function has been expanded with anticipated
regret and rejoicing as they result from comparisons between the possible outcomes
of a gamble and those that would occur if one were to choose differently (Bell 1982,
1983; Loomes and Sugden 1982). Similarly, the utility function has been expanded
with anticipated emotions as they result from comparisons between the possible
outcomes of a gamble with the expected value of the gamble: Anticipated disappointment
when “it could come out better,” and anticipated elation when “it could come out
worse” (Bell 1985; Loomes and Sugden 1986). Zero outcomes acquire value in the
same way as nonzero outcomes do: Either from between-gamble or within-gamble
comparisons. Thus, a zero outcome acquires negative value (by regret or disappointment)
if the comparison is with a gain, and positive value (by rejoicing or elation) if the
comparison is with a loss. In our analysis, however, zero outcomes are unique, in that
only they elicit counterfactual gains and losses, which will then serve as a reference
point for evaluating the zero outcomes themselves. Nonetheless, in Experiment 3,
dealing with zero outcomes in intertemporal choice, we obtained a result suggesting
that between-prospect comparisons of zero and nonzero outcomes also affected choice.
4.3 The framing of something, the framing of nothing
The investigation of framing effects in judgment and decision making began with
Tversky and Kahneman’s (1981) Asian Disease Problem, in which the lives of 600
people are threatened, and life-saving programs are examined. One group of participants
preferred a program that would save 200 people for sure over a program that
would save 600 people with a 1/3 probability, but save no people with a 2/3 probability.
Another group of participants preferred a program that would let nobody die with a
probability of 1/3, but let 600 people die with a 2/3 probability, over a program that
would let 400 people die for sure. Prospect theory ascribes this result to reference
dependence, i.e., v(0) = 0, and diminishing sensitivity, i.e., v is concave over gains, so
that v(600) < 3v(200), which works against the gamble, and convex over losses, so that
v(−600) > 3v(−200), which works in favor of the gamble.
Our interpretation is that some of the action may lie in the zero outcomes, rather than
the nonzero outcomes. Specifically, “save no people” brings to mind saving some
people, with which saving no people compares unfavorably, thus working against the
gamble. Similarly, “let nobody die” brings to mind letting somebody die, with which
letting nobody die compares favorably, thus working in favor of the gamble. Reference
dependence is fine, but designating zero outcomes means that v(0) ≠ 0, because the
reference point is no longer the status quo, but rather something imagined.
There is no shortage of competing views on framing effects (for one of many
discussions, see Mandel 2014), and our norm-theory approach to the Asian Disease
Problem is a partial explanation at best. Indeed, the reversal from an ample majority
(72%) choosing the safe option in the positive frame (saving lives) to an ample majority
(78%) choosing the risky option in the negative frame (giving up lives) is a large effect,
whereas the mutable-zero effect is a small effect, unlikely to be the sole responsible for
Tversky and Kahneman’s (1981) result. However, judgments and decisions are influenced
by the framing of zero outcomes, and we have shown that prevalent theories of
choice, Kahneman and Tversky’s (1979) prospect theory and Prelec and Loewenstein’s
(1998) double-entry mental accounting model, can explain how decisions are influenced
by mutable zeroes, on the shared understanding that nothing can have value, just
like everything else.

Results provide a cautionary tale for the naïve application of VAMs to teacher evaluation and other settings; they point to the possibility of the misidentification of sizable teacher “effects”where none exist
Teacher Effects on Student Achievement and Height: A Cautionary Tale. Marianne Bitler, Sean Corcoran, Thurston Domina, Emily Penner. NBER Working Paper No. 26480, November 2019. https://www.nber.org/papers/w26480
Abstract: Estimates of teacher “value-added” suggest teachers vary substantially in their ability to promote student learning. Prompted by this finding, many states and school districts have adopted value-added measures as indicators of teacher job performance. In this paper, we conduct a new test of the validity of value-added models. Using administrative student data from New York City, we apply commonly estimated value-added models to an outcome teachers cannot plausibly affect: student height. We find the standard deviation of teacher effects on height is nearly as large as that for math and reading achievement, raising obvious questions about validity. Subsequent analysis finds these “effects” are largely spurious variation (noise), rather than bias resulting from sorting on unobserved factors related to achievement. Given the difficulty of differentiating signal from noise in real-world teacher effect estimates, this paper serves as a cautionary tale for their use in practice.
6 Discussion
Schools and districts across the country want to employ teachers who can best help students to learn, grow, and achieve academic success. Identifying such individuals is integral to schools' successbutis also difficult to do in practice. In the face of data and measurement limitations, school leaders and state education departments seek low-cost, unbiased ways to observe and monitor the impact that their teachers have on students. Although many have criticized the use of VAMs to evaluate teachers, they remain a widely-used measure of teacher performance. In part, their popularity is due to convenience-while observational protocols which send observers to every teacher's classroom require expensive training and considerable resources to implement at scale, VAMs use existing data and can be calculated centrally at low cost. Further, VAMs are arguably less biased than many other evaluation methods that districts might use instead (Bacher-Hicks et al. 2017; Harris et al. 2014; Hill et al. 2011).
Yet questions remain about the reliability, validity, and practical use of VAMs. This paper interrogates concerns raised by prior research on VAMs and raises new concerns about the use of VAMs in career and compensation decisions. We explore the bias and reliability of commonlyestimated VAMs by comparing estimates of teacher value-added in mathematics and ELA with parallel estimates of teacher value-added on a well-measured biomarker that teachers should not impact: student height. Using administrative data from New York City, we find estimated teacher “effects”on height that are comparable in magnitude to actual teacher effects on math and ELA achievement, 0.22:compared to 0.29:and0.26:respectively. On its face, such results raise concerns about the validity of these models.
Fortunately, subsequent analysis finds that teacher effects on height are primarily noise, rather than bias due to sorting on unobserved factors. To ameliorate the effect of sampling error on value-added estimates, analysts sometimes “shrink” VAMs, scaling them by their estimated signal-to-noise ratio. When we apply the shrinkage method across multiple years of data from Kane and Staiger (2008), the persistent teacher “effect”on height goes away, becoming the expected (and known) mean of zero. This procedure is not always done in practice, however, and requires multiple years of classroom data for the same teachers to implement. Of course, for making hiring and firing decisions, it seems important to consider that value added measures which require multiple years of data to implement will likely permit identification of persistently bad teachers, but not provide a performance evaluation metric that can be met by teachers trying to improve their performance. In more realistic settings where the persistent effect is not zero, it is less clear that shrinkage would have a major influence on performance decisions, since it has modest effects on the relative rankings of teachers.
Taken together, our results provide a cautionary tale for the naïve application of VAMs to teacher evaluation and other settings. They point to the possibility of the misidentification of sizable teacher “effects”where none exist. These effects may be due in part to spurious variation driven by the typically small samples of children used to estimate a teacher's individual effect.

Political imagery on money relates to less political freedom & more gender inequality; more scientific & agricultural images on money relate to less economic, political freedom, human development & gender equality.
Using currency iconography to measure institutional quality. Kerianne Lawson. The Quarterly Review of Economics and Finance, Volume 72, May 2019, Pages 73-79. https://doi.org/10.1016/j.qref.2018.10.006
Highlights
• Countries with more political imagery on their money tend of have less political freedom and more gender inequality.
• More scientific & agricultural images on money correspond with less economic freedom, political freedom, human development & gender equality.
• More art related and cultural images on money correspond with higher economic freedom and human development index scores.
• More religious images on money correspond with less political freedom. And for OPEC countries, also less economic freedom.
• For non-Commonwealth nations, images of women on money correspond with more political freedom, human development & gender equality.
Abstract: The images on a country’s currency are purposefully chosen by the people or government to be representative of that country. Potentially, one could learn a lot about the economic and political climate of a country by simply looking at the pictures on its money. This paper reports indexes measuring the political, religious, and cultural/scientific content as well as the representation of women on currency notes. The analysis suggests that we can look to the iconography in currency as an indication of the quality of the institutions or socio-economic outcomes in that country.
2. Survey of related literature
The iconographic analysis of currency notes is a much-discussedtopic in disciplines outside economics. Sociologists, historians,anthropologists, and many others have looked at the images on cur-rency notes to discuss the social and political environment within acountry. There is even a ‘Bank Note of the Year’ contest held by theE-mail address: knl0013@mix.wvu.eduInternational Bank Note Society, which is decided by vote. Votersevaluate the “artistic merit, design, use of [color], contrast, bal-ance, and security features of each nomination” (IBNS Banknoteof the Year, 2018). It is widely accepted that the images on a coun-try’s currency hold significance, so they are worthy of discussion.
Most of the iconographic work on money looks at a single coun-try’s currency: Denmark (Sorensen, 2016), Ghana (Fuller, 2008),Indonesia (Strassler, 2009), Laos (Tappe, 2007), Scotland (Penrose& Cumming, 2011), Palestine (Wallach, 2011), Taiwan (Hymans &Fu, 2017), and the former Soviet Union (Cooper, 2009).

Highlights
• Countries with more political imagery on their money tend of have less political freedom and more gender inequality.
• More scientific & agricultural images on money correspond with less economic freedom, political freedom, human development & gender equality.
• More art related and cultural images on money correspond with higher economic freedom and human development index scores.
• More religious images on money correspond with less political freedom. And for OPEC countries, also less economic freedom.
• For non-Commonwealth nations, images of women on money correspond with more political freedom, human development & gender equality.
Abstract: The images on a country’s currency are purposefully chosen by the people or government to be representative of that country. Potentially, one could learn a lot about the economic and political climate of a country by simply looking at the pictures on its money. This paper reports indexes measuring the political, religious, and cultural/scientific content as well as the representation of women on currency notes. The analysis suggests that we can look to the iconography in currency as an indication of the quality of the institutions or socio-economic outcomes in that country.
2. Survey of related literature
The iconographic analysis of currency notes is a much-discussedtopic in disciplines outside economics. Sociologists, historians,anthropologists, and many others have looked at the images on cur-rency notes to discuss the social and political environment within acountry. There is even a ‘Bank Note of the Year’ contest held by theE-mail address: knl0013@mix.wvu.eduInternational Bank Note Society, which is decided by vote. Votersevaluate the “artistic merit, design, use of [color], contrast, bal-ance, and security features of each nomination” (IBNS Banknoteof the Year, 2018). It is widely accepted that the images on a coun-try’s currency hold significance, so they are worthy of discussion.
Most of the iconographic work on money looks at a single coun-try’s currency: Denmark (Sorensen, 2016), Ghana (Fuller, 2008),Indonesia (Strassler, 2009), Laos (Tappe, 2007), Scotland (Penrose& Cumming, 2011), Palestine (Wallach, 2011), Taiwan (Hymans &Fu, 2017), and the former Soviet Union (Cooper, 2009).

Narcissistic individuals were no better at accurately identifying other narcissists, but such individuals demonstrated considerable aversion to narcissistic faces
The Relation Between Narcissistic Personality Traits and Accurate Identification of, and Preference for, Facially Communicated Narcissism. Mary M. Medlin, Donald F. Sacco, Mitch Brown. Evolutionary Psychological Science, December 3 2019. https://link.springer.com/article/10.1007/s40806-019-00224-x
Abstract: When evaluating someone as a potential social acquaintance, people prefer affiliative, pleasant individuals. This necessitates the evolution of perceptual acuity in distinguishing between genuinely prosocial traits and those connoting exploitative intentions. Such intentions can be readily inferred through facial structures connoting personality, even in the absence of other diagnostic cues. We sought to explore how self-reported narcissism, a personality constellation associated with inflated self-views and exploitative intentions, might facilitate one’s ability to detect narcissism in others’ faces as means of identifying social targets who could best satisfy potential exploitative goals. Participants viewed pairs of male and female targets manipulated to connote high and low levels of narcissism before identifying which appeared more narcissistic and indicating their preference among each pair. Narcissistic individuals were no better at accurately identifying other narcissists, but such individuals demonstrated considerable aversion to narcissistic faces. Women higher in exploitative narcissism additionally preferred narcissistic female faces, while men high in exploitative narcissism demonstrated similar patterns of aversion toward narcissistic male faces. Findings provide evidence that narcissistic individuals may adaptively avoid those whom they identify as having similar exploitative behavior repertoire, though when considering the exploitive dimension of narcissism specifically, sex differences emerged.

Detecting Personality from Faces
A growing body of literature has demonstrated that people canaccurately determine personality information from facial cues (Little and Perrett2007;Parkinson2005; Sacco and Brown2018). Additionally, individuals are able to make these judgments based on limited exposure to others’faces, sometimesin as little as 50 ms (Borkenau et al. 2009; Penton-Voak et al. 2006; Zebrowitz and Collins 1997). The human ability to inferpersonality traits based on a single, cursory glance at another’s face may have evolved to facilitate efficient identification ofcooperative and exploitative conspecifics to motivate adaptiv eapproach and avoidance behavior, respectively (Borkenauet al. 2004; Sacco and Brown 2018; Zebrowitz and Collins 1997). For example, upon identifying the genuinely affiliative intentions in faces possessing extraverted facial structures,individuals consistently prefer such structures, particularlywhen motivated to seek affiliative opportunities (Brownet al.2019a). Conversely, the recognition of facial structuresconnoting exploitative intentions (e.g., psychopathy) elicits considerable aversion from perceivers (Brown et al.2017). This efficient identification of affiliative and exploitative conspecifics could thus expedite the avoidance of persons withgreater intention to harm others (Haselton and Nettle 2006).
Interpersonal Dynamics of Narcissism
Individuals known to attempt social espionage include thosewith personality types related to more manipulative behavioralrepertoires, including those high in narcissism. In fact, highly narcissistic individuals are particularly motivated to presentthemselves in a positive light toward others in the service of acquiring access to social capital (Rauthmann 2011). These deceptive interpersonal tactics have been shaped by an evolutionary arms race, wherein narcissistic individuals seek to de-ceive group members with such group members subsequently evolving greater capacity to recognize those likely to exploitthem (Cosmides and Tooby1992). Given that narcissistic individuals are especially prone to cheating (Baughman et al.2014), it would thus be adaptive to identify narcissistic individuals preemptively to reduce the likelihood of falling victimto their exploitation. Indeed, narcissism is readily inferred through various interpersonal behaviors, including dressing provocatively (Vazire et al.2008) and heightened selfie-taking (e.g., McCain et al.2016). These inferences are additionally possible through facial features, with narcissismpossessing a specific facial structure (Holtzman 2011). Given narcissistic individuals’ability to mask their intentions, through the absence of clear affective cues of manipulative intent, people may subsequently rely on facial structures todetect any such intention in an attempt to avoid those capable of inflicting considerable interpersonal costs, such as those associated with narcissism.
There is no doubt that associating with narcissistic individuals is costly, especially for cooperative individuals who fullyparticipate in group living. However, an association with anarcissist may be even more costly for another narcissist. Narcissistic individuals are, by their very nature, interpersonally dominant and unlikely to be exploited by others (Chenget al. 2010), which would position them to reap the benefits from social competitions with others (e.g., access to resources;Jonason et al. 2015). This could suggest that one narcissist could be a potential threat to another in their pursuit of socialresources if both individuals have similar exploitative aspirations. This recognition of threat could be particularly critical inthe mating arena, given that the presence of more narcissistic individuals would result in a reduction in short-term mating opportunities (Holtzman & Strube 2010). For this reason, itwould be expected for narcissists to demonstrate aversion forother narcissists in the service of reducing competition forresources and mates among those utilizing similarly exploitative interpersonal strategies.

What We Know, Are Still Getting Wrong, and Have Yet to Learn about the Relationships among the SAT, Intelligence and Achievement. Meredith C. Frey. J. Intell. 2019, 7(4), 26; December 2 2019, https://doi.org/10.3390/jintelligence7040026
Abstract: Fifteen years ago, Frey and Detterman established that the SAT (and later, with Koenig, the ACT) was substantially correlated with measures of general cognitive ability and could be used as a proxy measure for intelligence (Frey and Detterman, 2004; Koenig, Frey, and Detterman, 2008). Since that finding, replicated many times and cited extensively in the literature, myths about the SAT, intelligence, and academic achievement continue to spread in popular domains, online, and in some academic administrators. This paper reviews the available evidence about the relationships among the SAT, intelligence, and academic achievement, dispels common myths about the SAT, and points to promising future directions for research in the prediction of academic achievement.

3. What We Get Wrong about the SAT
Nearly a decade ago, Kuncel and Hezlett provided a detailed rebuttal to four misconceptions about the use of cognitive abilities tests, including the SAT, for admissions and hiring decisions: (1) a lack of relationship to non-academic outcomes, (2) predictive bias in the measurements, (3) a problematically strong relationship to socioeconomic status, and (4) a threshold in the measures, beyond which individual differences cease to be important predictors of outcomes [13]. Yet many of these misconceptions remain, especially in opinion pieces, popular books, blogs, and more troublingly, in admissions decisions and in the hearts of academic administrators (see [14] for a review for general audiences).
3.1. The SAT Mostly Measures Ability, Not Privilege
SAT scores correlate moderately with socioeconomic status [15], as do other standardized measures of intelligence. Contrary to some opinions, the predictive power of the SAT holds even when researchers control for socioeconomic status, and this pattern is similar across gender and racial/ethnic subgroups [15,16]. Another popular misconception is that one can “buy” a better SAT score through costly test prep. Yet research has consistently demonstrated that it is remarkably difficult to increase an individual’s SAT score, and the commercial test prep industry capitalizes on, at best, modest changes [13,17]. Short of outright cheating on the test, an expensive and complex undertaking that may carry unpleasant legal consequences, high SAT scores are generally difficult to acquire by any means other than high ability.
That is not to say that the SAT is a perfect measure of intelligence, or only measures intelligence. We know that other variables, such as test anxiety and self-efficacy, seem to exert some influence on SAT scores, though not as much influence as intelligence does. Importantly, though, group differences demonstrated on the SAT may be primarily a product of these noncognitive variables. For example, Hannon demonstrated that gender differences in SAT scores were rendered trivial by the inclusion of test anxiety and performance-avoidance goals [18]. Additional evidence indicates some noncognitive variables—epistemic belief of learning, performance-avoidance goals, and parental education—explain ethnic group differences in scores [19] and variables such as test anxiety may exert greater influence on test scores for different ethnic groups (e.g., [20], in this special issue). Researchers and admissions officers should attend to these influences without discarding the test entirely.

2. What We Know about the SAT
2.1. The SAT Measures Intelligence
Although the principal finding of Frey and Detterman has been established for 15 years, it bears repeating: the SAT is a good measure of intelligence [1]. Despite scientific consensus around that statement, some are remarkably resistant to accept the evidence of such an assertion. In the wake of a recent college admissions cheating scandal, Shapiro and Goldstein reported, in a piece for the New York Times, “The SAT and ACT are not aptitude or IQ tests” [6]. While perhaps this should not be alarming, as the authors are not experts in the field, the publication reached more than one million subscribers in the digital edition (the article also appeared on page A14 in the print edition, reaching hundreds of thousands more). And it is false, not a matter of opinion, but rather directly contradicted by evidence.
For years, SAT developers and administrators have declined to call the test what it is; this despite the fact that the SAT can trace its roots through the Army Alpha and Beta tests and back to the original Binet test of intelligence [7]. This is not to say that these organizations directly refute Frey and Detterman; rather, they are silent. On the ETS website, the word intelligence does not appear on the pages containing frequently asked questions, the purpose of testing, or the ETS glossary. If one were to look at the relevant College Board materials (and this author did, rather thoroughly), there are no references to intelligence in the test specifications for the redesigned SAT, the validity study of the redesigned SAT, the technical manual, or the SAT understanding scores brochure.
Further, while writing this paper, I entered the text “does the SAT measure intelligence” into the Google search engine. Of the first 10 entries, the first (an advertisement) was a link to the College Board for scheduling the SAT, four were links to news sites offering mixed opinions, and fully half were links to test prep companies or authors, who all indicated the test is not a measure of intelligence. This is presumably because acknowledging the test as measure of intelligence would decrease consumers’ belief that scores could be vastly improved with adequate coaching (even though there is substantial evidence that coaching does little to change test scores). One test prep book author’s blog was also the “featured snippet”, or the answer highlighted for searchers just below the ad. In the snippet, the author made the claims that “The SAT does not measure how intelligent you are. Experts disagree whether intelligence can be measured at all, in truth” [8]—little wonder, then, that there is such confusion about the test.
2.2. The SAT Predicts College Achievement
Again, an established finding bears repeating: the SAT predicts college achievement, and a combination of SAT scores and high school grades offer the best prediction of student success. In the most recent validity sample of nearly a quarter million students, SAT scores and high school GPA combined offered the best predictor of first year GPA for college students. Including SAT scores in regression analyses yielded a roughly 15% increase in predictive power above using high school grades alone. Additionally, SAT scores improved the prediction of student retention to the second year of college [9]. Yet many are resistant to using standardized test scores in admissions decisions, and, as a result, an increasing number of schools are becoming “test optional”, meaning that applicants are not required to submit SAT or ACT scores to be considered for admission. But, without these scores, admissions officers lose an objective measure of ability and the best option for predicting student success.
2.3. The SAT Is Important to Colleges
Colleges, even nonselective ones, need to identify those individuals whose success is most likely, because that guarantees institutions a consistent revenue stream and increases retention rates, seen by some as an important measure of institutional quality. Selective and highly selective colleges further need to identify the most talented students because those students (or, rather, their average SAT scores) are important for the prestige of the university. Indeed, the correlation between average SAT/ACT scores and college ranking in U.S. News & World Report is very nearly 0.9 [10,11].
2.4. The SAT Is Important to Students
Here, it is worth recalling the reason the SAT was used in admissions decisions in the first place: to allow scholarship candidates to apply for admission to Harvard without attending an elite preparatory school [7]. Without an objective measure of ability, admissions officers are left with assessing not just the performance of the student in secondary education, but also the quality of the opportunities afforded to that student, which vary considerably across the secondary school landscape in the United States. Klugman analyzed data from a nationally representative sample and found that high school resources are an important factor in determining the selectivity of colleges that students apply for, both in terms of programmatic resources (e.g., AP classes) and social resources (e.g., socioeconomic status of other students) [12]. It is possible, then, that relying solely on high school records will exacerbate rather than reduce pre-existing inequalities.
Of further importance, performance on the SAT predicts the probability of maintaining a 2.5 GPA (a proxy for good academic standing) [9]. Universities can be rather costly and admitting students with little chance of success until they either leave of their own accord or are removed for academic underperformance—with no degree to show and potentially large amounts of debt—is hardly the most just solution.

Merely Possessing a Placebo Analgesic Reduced Pain Intensity: Preliminary Findings from a Randomized Design
Merely Possessing a Placebo Analgesic Reduced Pain Intensity: Preliminary Findings from a Randomized Design. Victoria Wai-lan Yeung, Andrew Geers, Simon Man-chun Kam. Current Psychology, February 2019, Volume 38, Issue 1, pp 194–203. https://link.springer.com/article/10.1007/s12144-017-9601-0
Abstract: An experiment was conducted to examine whether the mere possession of a placebo analgesic cream would affect perceived pain intensity in a laboratory pain-perception test. Healthy participants read a medical explanation of pain aimed at inducing a desire to seek pain relief and then were informed that a placebo cream was an effective analgesic drug. Half of the participants were randomly assigned to receive the cream as an unexpected gift, whereas the other half did not receive the cream. Subsequently, all participants performed the cold-pressor task. We found that participants who received the cream but did not use it reported lower levels of pain intensity during the cold-pressor task than those who did not receive the cream. Our findings constitute initial evidence that simply possessing a placebo analgesic can reduce pain intensity. The study represents the first attempt to investigate the role of mere possession in understanding placebo analgesia. Possible mechanisms and future directions are discussed.

Discussion
Past research has demonstrated that placebo analgesics can increase pain relief. The primary focus was on pain relief that occurred following the use of the placebo-analgesic treatment. We tested the novel hypothesis that merely possessing a placebo analgesic can boost pain relief. Consistent with this hypothesis, participants who received but did not use what they were told was a placebo-analgesic cream reported lower levels of pain intensity in a cold-pressor test than did participants who did not possess the cream. To our knowledge, the present data are the first to extend research on the mere-possession phenomenon (Beggan 1992) to the realm of placebo analgesia.
Traditional placebo studies have included both possessing and consuming: Participants first possess an inert object, then they consume or use it and report diminished pain as a consequence (Atlas et al. 2009; de la Fuente-Fernández et al. 2001; Price et al. 2008; Vase et al. 2003). The current study provided initial evidence that consuming or using the placebo analgesia is unnecessary for the effect. However, it remains possible that the effect would be enhanced were possession to be accompanied by consumption or use. This and related hypotheses could be tested in future studies.
In the current experiment, we measured several different variables (fear of pain, dispositional optimism, desire for control, suggestibility, and trait anxiety) that could be considered as potential moderators of the observed placebo-analgesia effect. However, none of them proved significant. Although we remain unsure of the processes responsible for the mere possession effect we observed, a previously offered account may be applicable. Specifically, participants’ pain reduction may have been induced by a positive expectation of pain relief that was mediated by an elevated perception of self efficacy in coping with pain (see Peck and Coleman 1991; Spanos et al. 1989). To directly test this possibility in further research, it would be important to measure participants’ self-perceived analgesic efficacy in relation to the mere-possession effect.
It is possible that the mere possession of what participants were told was an analgesic cream induced a positive affect through reception of a free gift. The affect may have influenced participants’ perceived pain intensity. In order to test this possibility, we looked more closely at an item in the State-Anxiety Subscale (Spielberger et al. 1983), specifically, BI feel happy^. Participants in the mere-possession condition did not feel happier (M = 2.47, SD = .96) than those in the nopossession condition (M = 2.80, SD = .70), t(37) = 1.22, p = .23, d = .38, CI95% = [−0.24, 1.00]. Nevertheless, since the participants completed the State-Anxiety Subscale after they received the cream and following the pain-perception test, in order to strictly delineate the effect of affect from other factors, future research should measure participants’ mood after they receive the cream and prior to the pain-perception test. In our study, participants’ pain reduction could not be attributed to the mere-exposure effect because participants in both conditions were initially exposed to the sample of the cream simultaneously. The only difference between the two conditions was that participants in the mere-possession condition were subsequently granted ownership of the sample cream, but participants in the no-possession condition did not.
A significant group difference in pain perception appeared in the analysis of the MPQ results but not those from the VAS. There are at least two possible reasons for this outcome. First, prior researchers had demonstrated that the VAS is sensitive to changes in perceived pain when participants are asked to continuously report their pain intensity (Joyce et al. 1975; Schafer et al. 2015).
In our study, participants reported their pain intensity only once. Whether a significant group difference would be observed if the VAS was to be administered several times within the 1-min immersion duration is presently unknown. Second, it should be noted that VAS may not be sensitive to Asians’ pain perception (Yokobe et al. 2014). No similar observation has been made about results from the use of the MPQ.
Our findings add to the placebo-analgesia literature by indicating potential directions for further research, including limitations of our study that will need to be considered. First, we induced participants to seek the reduction of pain and to anticipate the effectiveness of the placebo. Doing so may have optimized the incidence of the mere-possession effect. Second, although our data demonstrated that the effect we observed was not due to a positive feeling in response to receiving a free gift, future studies might involve a control condition in which the gift is not purported to relieve pain. Third, our participants were healthy university students of Chinese ethnicity. Prior research has shown that cultural background influences pain perception (Callister 2003; Campbell and Edwards 2012). Future researchers may extend the ethnic and cultural range of the participants in an effort to generalize the current findings. Moreover, it seems critical to conduct future research with clinical patients who are in demonstrable pain. Lastly, it is unclear whether the mere-possession effect extends to other types of pain-induction tasks, such as those involving heat (e.g., Mitchell et al. 2004; Duschek et al. 2009) or loud noise (e.g., Brown et al. 2015; Rose et al. 2014).
Abstract: An experiment was conducted to examine whether the mere possession of a placebo analgesic cream would affect perceived pain intensity in a laboratory pain-perception test. Healthy participants read a medical explanation of pain aimed at inducing a desire to seek pain relief and then were informed that a placebo cream was an effective analgesic drug. Half of the participants were randomly assigned to receive the cream as an unexpected gift, whereas the other half did not receive the cream. Subsequently, all participants performed the cold-pressor task. We found that participants who received the cream but did not use it reported lower levels of pain intensity during the cold-pressor task than those who did not receive the cream. Our findings constitute initial evidence that simply possessing a placebo analgesic can reduce pain intensity. The study represents the first attempt to investigate the role of mere possession in understanding placebo analgesia. Possible mechanisms and future directions are discussed.

Discussion
Past research has demonstrated that placebo analgesics can increase pain relief. The primary focus was on pain relief that occurred following the use of the placebo-analgesic treatment. We tested the novel hypothesis that merely possessing a placebo analgesic can boost pain relief. Consistent with this hypothesis, participants who received but did not use what they were told was a placebo-analgesic cream reported lower levels of pain intensity in a cold-pressor test than did participants who did not possess the cream. To our knowledge, the present data are the first to extend research on the mere-possession phenomenon (Beggan 1992) to the realm of placebo analgesia.
Traditional placebo studies have included both possessing and consuming: Participants first possess an inert object, then they consume or use it and report diminished pain as a consequence (Atlas et al. 2009; de la Fuente-Fernández et al. 2001; Price et al. 2008; Vase et al. 2003). The current study provided initial evidence that consuming or using the placebo analgesia is unnecessary for the effect. However, it remains possible that the effect would be enhanced were possession to be accompanied by consumption or use. This and related hypotheses could be tested in future studies.
In the current experiment, we measured several different variables (fear of pain, dispositional optimism, desire for control, suggestibility, and trait anxiety) that could be considered as potential moderators of the observed placebo-analgesia effect. However, none of them proved significant. Although we remain unsure of the processes responsible for the mere possession effect we observed, a previously offered account may be applicable. Specifically, participants’ pain reduction may have been induced by a positive expectation of pain relief that was mediated by an elevated perception of self efficacy in coping with pain (see Peck and Coleman 1991; Spanos et al. 1989). To directly test this possibility in further research, it would be important to measure participants’ self-perceived analgesic efficacy in relation to the mere-possession effect.
It is possible that the mere possession of what participants were told was an analgesic cream induced a positive affect through reception of a free gift. The affect may have influenced participants’ perceived pain intensity. In order to test this possibility, we looked more closely at an item in the State-Anxiety Subscale (Spielberger et al. 1983), specifically, BI feel happy^. Participants in the mere-possession condition did not feel happier (M = 2.47, SD = .96) than those in the nopossession condition (M = 2.80, SD = .70), t(37) = 1.22, p = .23, d = .38, CI95% = [−0.24, 1.00]. Nevertheless, since the participants completed the State-Anxiety Subscale after they received the cream and following the pain-perception test, in order to strictly delineate the effect of affect from other factors, future research should measure participants’ mood after they receive the cream and prior to the pain-perception test. In our study, participants’ pain reduction could not be attributed to the mere-exposure effect because participants in both conditions were initially exposed to the sample of the cream simultaneously. The only difference between the two conditions was that participants in the mere-possession condition were subsequently granted ownership of the sample cream, but participants in the no-possession condition did not.
A significant group difference in pain perception appeared in the analysis of the MPQ results but not those from the VAS. There are at least two possible reasons for this outcome.

A message coming from behind is interpreted as more negative than a message presented in front of a listener; social information presented from behind is associated with uncertainty and lack of control
Rear Negativity:Verbal Messages Coming from Behind are Perceived as More Negative. Natalia Frankowska Michal Parzuchowski Bogdan Wojciszke Michał Olszanowski Piotr Winkielman. European Journal of Social Psychology, 29 November 2019. https://doi.org/10.1002/ejsp.2649
Abstract: Many studies have explored the evaluative effects of vertical (up/down) or horizontal (left/right) spatial locations. However, little is known about the role of information that comes from the front and back. Based on multiple theoretical considerations, we propose that spatial location of sounds is a cue for message valence, such that a message coming from behind is interpreted as more negative than a message presented in front of a listener. Here we show across a variety of manipulations and dependent measures that this effect occurs in the domain of social information. Our data are most compatible with theoretical accounts which propose that social information presented from behind is associated with uncertainty and lack of control, which is amplified in conditions of self‐relevance.

General Discussion
Rear Negativity Effect in Social Domain
The present series of studies document a “rear negativity effect” – a phenomenon where perceivers evaluate social information coming from a source located behind them as more negative than identical information coming from a source located in front of them. We observed this effect repeatedly for a variety of verbal messages (communications in a language incomprehensible to the listeners, neutral communications, positive or negative words spoken in participants’ native language), for a variety of dependent variables (ratings, reaction times), and among different subject populations (Poland, US). Specifically, in Study 1, Polish subjects interpreted Chinese sentences as more negative when presented behind the listener. In Study 2, Polish subjects evaluated feedback from a bogus test as indicative of poorer results when it was presented behind, rather than in front of them. In Study 3, Polish subjects evaluated the Chinese sentences as the most negative when they were played from behind and when they supposedly described in-group (i.e., Polish) members. In Study 4, US subjects judged negative traits more quickly when the traits were supposedly describing self-relevant information and were played behind the listener.
Explanations of the effect
The current research extends previous findings that ecological, naturally occurring, sounds are detected quicker and induce stronger negative emotions when presented behind participants (Asutay & Västfjäll, 2015). Critically, the current studies document this effect in the domain of social information and show it to be stronger or limited to processing of self-relevant information, whether this relevance was induced by reference of messages to the self or to an in-group. Our characterization of the “rear negativity” effect in the social domains is compatible with several considerations and theoretical frameworks. Most generally, the effect is consistent with a notion common in many cultures that things that take place “behind one’s back” are generally negative. However, the accounts of why this is vary – ranging from metaphor theory, simple links between processing ease and evaluation, affordance and uncertainty theories, attentional as well as emotion-appraisal accounts.
Spatial metaphors. People not only talk metaphorically, but also think metaphorically, activating mental representations of space to scaffold their thinking in a variety of non-spatial domains, including time (Torralbo et al., 2006), social dominance (Schubert, 2005), emotional valence (Meier & Robinson, 2004), similarity (Casasanto, 2008), and musical pitch (Rusconi et al., 2006). Thus, it is interesting to consider how our results fit with spatial metaphor theories. Specifically, perhaps when people hear a message, they activate a metaphor and, as a result, evaluate the information as being more unpleasant, dishonest, disloyal, false, or secretive when coming from behind than from the front. Our results suggest that reasons for the rear negativity of verbal information go beyond simple metaphorical explanation. This is because this negativity occurs solely or is augmented for information that is personally relevant to the listener, and that it occurs even in paradigms that require fast automatic processing, leaving little time for activation of a conceptual metaphor. Of course, once the valence-to-location mapping is metaphorically established, it could manifest quickly and be stronger for personally-important information. In short, it would be useful to conduct further investigation of the metaphorical account, perhaps by manipulating the degree of metaphor activation, its specific form or its relevance.
Associative learning and cultural interpretations. The valence-location link could have metaphorical origins but could also result from an individual’s personal experiences that create a mental association (Casasanto, 2009). One could potentially examine an individual’s personal history and her cultural setting and see whether a rear location has linked to negative events. Specifically, everyday experiences could lead to a location-valence association. For example, during conversations an individual may have encountered more high-status people in front of her rather than behind, thus creating an association of respect and location. Or, the individual may have experienced more sounds from behind that are associated with criticism or harassment rather than compliments. Beyond an individual’s own associative history, there is also culture. For example, European cultures used to have a strong preference for facing objects of respect (e.g., not turning your back to the monarch, always facing the church altar). As a result, sounds coming from behind may be interpreted as coming from sources of less respect. More complex interpretative processes may also be involved. As discussed in the context of Study 3, hearing from behind from an out-group about one’s own group can increase the tendency to attribute negative biases to the outgroup. It can lead then to interpreting the outgroup’s utterances as being more critical or even threatening, especially when such utterances are negative (e.g. Judd et al., 2005; Yzerbyt, Judd, & Muller, 2009). However, these speculations are clearly post-hoc and further research is needed to understand the full pattern of results. Simila [cut here!!!!]
Fluency. One simple mechanistic explanation of the current results draws on the idea that difficult (disfluent) processing lowers stimulus evaluations, while easy (fluent) processing enhances evaluations (Winkielman et al., 2003). People usually listen to sounds positioned in front. So, it is possible that sounds coming from behind are perceived as more negative because they are less fluent (or less familiar). However, fluency, besides increasing the experience of positive affect, is also manifested through the speed of processing (i.e. fluent stimuli are recognized faster). Yet, it is worth mentioning that in Study 4 we did not observe the effect of location on overall reaction times. Moreover, previous research suggests that if anything, information presented from behind is processed faster (Asutay & Västfjäll, 2015). For these reasons, and because the effect is limited to self-relevant information, the fluency approach does not explain the presented effects. However, future research may consider a potential of fluency manipulations to reduce the rear negativity effect.
Affordances. Yet another possible explanation draws on classic affordance theory suggesting that the world is perceived not only in terms of objects and their spatial relationships, but also in terms of one’s possible actions (Gibson, 1950, 1966). Thus, verbal information located in the back may restrict possible actions to the listener and hence may cause negative evaluation. However, this explanation is weakened by our observations that reward negativity effect also appears when participants are seated and blindfolded, so they cannot see in the front. Further examination of this account could include a set-up that involves restricting participants’ hands or using virtual reality to manipulate perspective and embodied affordances.

Neural correlates of moral goodness & moral beauty judgments: Moral beauty judgment induced greater brain activity implicated in theory of mind, suggesting that it needs to understand the others' mental states, unlike moral goodness
Neural correlates of moral goodness and moral beauty judgments. Qiuping Cheng et al. Brain Research, Volume 1726, January 1 2020, 146534. https://doi.org/10.1016/j.brainres.2019.146534
Highlights
• Moral goodness judgment and moral beauty judgment recruited the common brain activity in the left inferior OFC.
• Moral goodness judgment mainly relied on the emotional facet of moral cognition, but moral beauty judgment relied on both the rational and emotional components of moral cognition.
• Moral beauty judgment induced greater brain activity implicated in theory of mind (ToM), suggesting that it needs to understand the others` mental states but moral goodness judgment does not.
• Moral beauty judgment also activated a cortical network that is considered mainly responsible for the processing of empathy, indicating that it involves empathic concerns for others.
• The brain harbors neural systems for common and for domain-specific evaluations for moral goodness and moral beauty judgments.
Abstract: The objects of moral goodness and moral beauty judgments both generally refer to the positive moral acts or virtues of humans, and goodness must precede moral beauty. The main difference is that moral beauty, but not moral goodness, triggers emotional elevation. However, little is known about the neural mechanisms involved in both judgments. In the current study, 28 healthy female participants were scanned when they rated the good and beautiful extent of positive moral acts in daily life depicted in scene drawings to investigate the neural systems supporting moral goodness and moral beauty, specifically to test whether neural activity associated with moral beauty is same or different than moral goodness. The conjunction analysis of the contrasts between moral goodness judgment and moral beauty judgment identified the involvement of the left inferior orbitofrontal cortex (OFC), suggesting that the two judgments recruited the activity of a common brain region. Importantly, compared with the moral goodness judgment, the moral beauty judgment induced greater activity in more advanced cortical regions implicated in elevated emotions, including the anterior cingulate cortex (ACC), medial prefrontal cortex (mPFC), superior frontal gyrus (SFG) and the left temporo-parietal junction (TPJ). These regions have been strongly correlated with the cognitive aspects of moral cognition, including theory of mind (ToM). In addition, moral beauty judgment also activated brain regions implicated in empathy including the midline structures and the anterior insula. Based on these results, the brain harbors neural systems for common and for domain-specific evaluations of moral goodness and moral beauty judgments. Our study thus provides novel and compelling neural evidence for the essence of moral beauty and advances the current knowledge of the neural mechanisms underlying the beauty-is-good stereotype.
1. Introduction
Imagine the following scenario: A young man is helping an elderly person cross the street. Now, please answer the first question: do you think this young man is morally good? Then, for the same behavior, please answer another question: do you think this young man displays inner beauty? Comparing these two questions, the first question is actually a moral goodness judgment in which an observer endows moral values to certain individual based on principles that have become a general law (Kant, (1785/1993), Haidt, 2007) and judges him a morally good person based on quick intuition – gut feelings (Haidt and Bjorklund, 2008, Hume, (1777/2006)., Greene, 2007, Greene, 2017). Meanwhile, the second question essentially reflects a moral beauty judgment in which an observer identifies a kind-natured person as displaying inner beauty based on an understanding of social rules and involves highly developed moral emotions (Diessner et al., 2006, Diessner et al., 2008, Haidt, 2003a, Haidt, 2003b, Haidt, 2007, Keltner and Haidt, 2003, Wang et al., 2015). Morality is considered as the sets of customs and values that are embraced by humans to guide social conduct (Moll et al., 2005) and is a product of evolutionary pressure that have shaped social cognitive and motivational mechanisms (Schulkin, 2000). Moral goodness and moral beauty judgments both belong to moral judgments, which are strongly influenced by emotional drives rooted in socio-emotional instincts (Darwin, 1874/1997), and they share a very important characteristic, that is, the object of both judgments is universal human virtues, for example, a kindness virtue of helping others in the scenario described above. These similarities prompt a critical question: Are the moral goodness judgment and moral beauty judgment the same? What about the neural correlates of two judgments?
Most objects of beauty judgments are pleasing to the eye and ear (Chatterjee and Vartanian, 2016), but another type of beauty, inner beauty, which is also delicately called moral beauty, has been identified (Haidt and Keltner, 2004). Moral beauty primarily addresses the natural beauty of persons and the beauty of their acts, states of character, and the like (Kosman, 2010), and emphasizes beauty as inherent to the individual’s inward appearance. It expresses several positive and culturally universal virtues that are independent of perceivable physical forms, such as wisdom, courage, humanity (love and kindness), and justice (Peterson and Seligman, 2004), similar to the object of moral goodness. Haidt and Keltner (2004) defined moral beauty as “the ability to find, recognize, and take pleasure in the existence of goodness in the social worlds” (p.537). Moral beauty and moral goodness are closely related, because the virtues of moral beauty are also generally considered signs of moral goodness (Diessner et al., 2006). According to Haidt and Keltner (2004), moral beauty is experienced when faced with displays of virtue or moral goodness in the social world (Haidt and Keltner, 2004, Güsewell and Ruch, 2012). Moral acts with virtues are “positive stimuli” and usually viewed as good and beautiful. Each is pleasant and offers potential for reward. According to Darwin, moral judgments are influenced by emotional processes, and these ‘social-emotional instincts’ are central for the feeling of pleasure when helping others and of unease when harming others (Darwin, 1874/1997). Individuals with inner beauty are not necessarily externally beautiful, but they must be morally good, because if beauty is not applied to a work of art, goodness must precede beauty and neither arises as a consequence of beauty nor is defined teleologically as a means to its accomplishment (Kosman, 2010). It seems that moral beauty and moral goodness are the same, at least, there is a partial overlap between the two judgments.
The remarks that “what is beautiful is good…” (Sappho, Fragments, No. 101) and that “physical beauty is the sign of an internal beauty, a spiritual and moral beauty…” (Schilier, 1882) indicates that the beauty-is-good stereotype is prevalent in human society (Berscheid and Walster, 1974, Dion et al., 1972, Tsukiura and Cabeza, 2011). For example, people with a better physical appearance receive more positive evaluations from others (Eagly et al., 1991, Feingold, 1992) and more preferential treatments in many aspects of life (Langlois et al., 2000), such as greater hiring opportunities (Marlowe et al., 1996) and earning a better income (Hamermesh and Biddle, 1994). Thus, beautiful individuals appear to be more positively associated with a socially desirable personality and moral traits (Dion et al., 1972, Eagly et al., 1991, Feingold, 1992, Langlois et al., 2000). The reliance on attractive features to infer moral character suggests a close relationship between beauty and moral valuation (Ferrari et al., 2017). One is capable of, at first sight, considering another human being attractive or unattractive while at the same time assigning values to that person. Tsukiura and Cabeza (2011) scanned participants with functional magnetic resonance imaging (fMRI) while they made attractiveness judgments about faces and goodness judgments about hypothetical acts to investigate the neural mechanisms underlying the relationship between beauty judgment and moral judgment. Both higher attractiveness ratings of faces and higher goodness ratings of moral acts correlated with increased activation of the orbitofrontal cortex (OFC). Takahashi et al., 2008, Wang et al., 2015 also observed relationships between the neural correlates of beauty judgment and moral feeling with the activation of the OFC. OFC is known as a region associated with processing positive emotions and reward, with its activity increasing as a function of beauty and moral goodness. These functional imaging studies support the idea of similar contribution of OFC to beauty and moral goodness judgments. However, no study has directly investigated whether the moral beauty judgment also shares the same neural correlate as the moral goodness judgment.
Although moral beauty objectively refers to the same human act or virtue as moral goodness, they differ in terms of the emotional response and motivation (Diessner et al., 2006, Diessner et al., 2008, Keltner and Haidt, 2003). Diessner et al. (2008) conceive “responsiveness to goodness and beauty” as a continuum, stretching from cognitive appreciation to deep engagement, with all imaginable intermediate degrees of emotional involvement. Cognitive appreciation without engagement is conceivable, but engagement without appreciation is not. When identifying a positive act of one person as moral goodness, an observer quickly assesses the morality of a certain behavior but remains emotionally unmoved and un-elevated (Diessner et al., 2006, Güsewell and Ruch, 2012). It seems that the emotional process influences the moral goodness and moral beauty judgments in the different patterns. An act of moral goodness is cognitively experienced as such without emotional involvement (Diessner et al., 2008). However, when judging the same act of moral goodness as moral beauty, the observer’s emotions are presumed to have been moved and elevated after observing manifest moral virtues in human act (Diessner et al., 2006, Haidt, 2003a, Haidt, 2003b, Haidt, 2007, Keltner and Haidt, 2003, Pohling and Diessner, 2016).
Moral elevation is the emotional response to witnessing acts of moral beauty and is particularly elicited by moral beauty. It triggers a distinctive feeling in the chest of warmth and expansion and causes a generalized desire to become a better person oneself and creates a tendency toward prosocial actions that trigger similar good behaviors in a similar scenario (Algoe and Haidt, 2009, Diessner et al., 2013, Haidt, 2003a, Haidt, 2003b, Haidt and Keltner, 2004, Schnall et al., 2010, Shiota et al., 2014, Van de Vyver and Abrams, 2015, Greene, 2017). Moral elevation directs the focus on others (Haidt, 2003) by understanding their mental states (i.e., theory of mind, ToM) and vicariously experiencing similar feelings (i.e., empathy). With regard to cognitive changes, it was assumed (Haidt, 2003) and found (Freeman et al., 2009) that elevation induces optimistic thoughts of people and humanity (Pohling and Diessner, 2016). Researchers have observed the recruitments of brain regions often implicated in mentalizing (ToM and empathy) behavior (Bzdok et al., 2012, Farrow et al., 2001, Han and Northoff, 2008, Harenski et al., 2012, Johnson et al., 2002, Maratos et al., 2001, Moll et al., 2002, Moll et al., 2005, Reniers et al., 2012, Saxe and Kanwisher, 2003) under the condition of moral elevation, including the medial prefrontal cortex (mPFC) and bilateral temporo-parietal junction (TPJ) implicated in ToM; the midline structures (anterior and posterior cingulate, precuneus) and the anterior insula implicated in empathy (Bzdok et al., 2012, Englander et al., 2012, Immordino-Yang et al., 2009, Lewis, 2014, Piper et al., 2015). According to recent neuropsychological evidence, moral beauty not only involves the OFC (Takahashi et al., 2008), which is activated in both external beauty and moral goodness judgments (Tsukiura and Cabeza, 2011), but also recruits the activity of similar brain regions as moral elevation, including the mPFC, anterior cingulate cortex (ACC), precuneus/PCC, insula and TPJ (Luo et al., 2019, Wang et al., 2015, Wen et al., 2017). However, researchers did not directly conclude a correlation between the activation of these brain regions involved in moral beauty with emotional elevation.
The beauty-is-good stereotype has been the topic of many social cognition studies, however, most focused on the dynamic relationship between the external beauty judgment and moral goodness judgment. The similarity and differences in the neural correlates between the moral beauty judgment and moral goodness judgment remain unknown. To the best of our knowledge, no previous study has directly compared brain activity during both judgments. Therefore, we designed an fMRI experiment to address this issue. During the scan, scene drawings depicting positive moral acts with different behavioral levels in daily life were presented on the computer screens while participants rated the extent of moral goodness (MG) and moral beauty (MB) presented by the main character in scene drawings. Then, we input the rating scores of each participant into the parametric modulators in SPM12 to identify regions in which the activity changed as a function of behavioral ratings. With this parametric approach, we were able to locate the brain regions involved in the moral beauty judgment and the moral goodness judgment and further explore the similarities and differences between them. Correspondingly, two hypotheses were generated. According to the findings reported in the previous literature, the brain activity in the OFC overlapped not only in the external beauty and moral goodness judgments (Tsukiura and Cabeza, 2011) but also in external beauty and moral beauty judgments (Luo et al., 2019, Wang et al., 2015). We initially hypothesized that the OFC would also be a shared brain region associated with moral beauty and moral goodness judgments, because both judgments refer to the same virtuous acts that have been approved by social culture. Virtue acts are “positive stimuli”, which usually lead to positive emotions and then facilitate appropriate behavioral responses to potential rewards (Fredrickson, 1998). According to neuroimaging studies, abstract rewards induced by social approval from others recruit the OFC (Haber and Knutson, 2010). Additionally, because moral beauty triggers emotional elevation and moral elevation activates brain regions involved in ToM and empathic process, we hypothesized that the moral beauty judgment would also recruit these advanced brain regions that are responsible for processing others mental states including mPFC and TPJ, and responsible for sharing others emotions including ACC, precuneus/PCC, and anterior insula.
Chinese astrology, numerological preferences, timing of births and the long-term effect on schooling: People born on auspicious days are more likely to attend college
Numerological preferences, timing of births and the long-term effect on schooling. Cheng Huang, Xiaojing Ma, Shiying Zhang, Qingguo Zhao. Journal of Population Economics, December 2 2019. https://link.springer.com/article/10.1007/s00148-019-00758-1
Abstract: Cultural beliefs may affect demographic behaviors. According to traditional Chinese astrology, babies born on auspicious days will have good luck in their lifetime, whereas those born on inauspicious days will have bad luck. Using administrative data from birth certificates in Guangdong, China, we provide empirical evidence on the short-term effects of such numerological preferences. We find that approximately 3.9% extra births occur on auspicious days and 1.4% of births are avoided on inauspicious days. Additionally, there is a higher male/female sex ratio for births on auspicious days. Since such manipulation of the birthdate is typically performed through scheduled C-sections, C-section births increase significantly on auspicious days. Moreover, we use a second dataset to examine the long-term effect of numerological preferences and find that people born on auspicious days are more likely to attend college.
