Wu, K., & Dunning, D. (2017). Hypocognition: Making Sense of the Landscape Beyond One’s Conceptual Reach. Review of General Psychology, http://dx.doi.org/10.1037/gpr0000126
Abstract: People think, feel, and behave within the confines of what they can conceive. Outside that conceptual landscape, people exhibit hypocognition (i.e., lacking cognitive or linguistic representations of concepts to describe ideas or explicate experiences). We review research on the implications of hypocognition for cognition and behavior. Drawing on the expertise and cross-cultural literatures, we describe how hypocognition impoverishes one’s mental world, leaving cognitive deficits in recognition, explanation, and memory while fueling social chauvinism and conflict in political and cultural spheres. Despite its pervasive consequences, people cannot be expected to identify when they are in a hypocognitive state, mistaking what they conceive for the totality of all that there is. To the extent that their channel of knowledge becomes too narrow, people risk submitting to hypocognition’s counterpart, hypercognition (i.e., the mistaken overapplication of other available conceptual notions to issues outside their actual relevance).

We remember lies better than truths, but we expect the opposite
Besken, M. (2017). Generating Lies Produces Lower Memory Predictions and Higher Memory Performance Than Telling the Truth: Evidence for a Metacognitive Illusion. Journal of Experimental Psychology: Learning, Memory, and Cognition, http://dx.doi.org/10.1037/xlm0000459
Abstract: Manipulations that induce disfluency during encoding generally produce lower memory predictions for the disfluent condition than for the fluent condition. Similar to other manipulations of disfluency, generating lies takes longer and requires more mental effort than does telling the truth; hence, a manipulation of lie generation might produce patterns similar to other types of fluency for memory predictions. The current study systematically investigates the effect of a lie-generation manipulation on both actual and predicted memory performance. In a series of experiments, participants told the truth or generated plausible lies to general knowledge questions and made item-by-item predictions about their subsequent memory performance during encoding, followed by a free recall test. Participants consistently predicted their memory performance to be higher for truth than for lies (Experiments 1 through 4), despite their typically superior actual memory performance for lies than for the truth (Experiments 1 through 3), producing double dissociations between memory and metamemory. Moreover, lying led to longer response latencies than did telling the truth, showing that generating lies is in fact objectively more disfluent. An additional experiment compared memory predictions for truth and lie trials via a scenario about the lie-generation manipulation used in the present study, which revealed superior memory predictions of truth than of lies, providing proof for a priori beliefs about the effects of lying on predicted memory (Experiment 5). The effects of the current lie-generation manipulation on metamemory are discussed in light of experience-based and theory-based processes on making judgments of learning. Theoretical and practical implications of this experimental paradigm are also considered.

My commentary: We remember lies better than truths, but we expect the opposite ("revealed superior memory predictions of truth than of lies, providing proof for a priori beliefs about the effects of lying on predicted memory").

Cheap Renewable Contracts Could Be Options In Disguise

When prices tumble for a product or service, there is generally an observable reason. It might be a cunning technological fix that dramatically boosts productivity, for instance, or the sudden slide in a key input cost. But nothing so obvious can convincingly explain why it is suddenly much cheaper to produce electricity from offshore wind turbines.

The latest round of renewable auctions has seen two big projects awarded contracts guaranteeing a fixed price of £57.50 per megawatt hour for their output when the blades start turning sometime in the next decade. That is a very big dip from the first round, which required subsidies of some £150/MWh to be profitable. Even the cheapest of previous vintages were north of £110.
It is not so long since British wind power bosses were vowing — amid widespread scepticism — that they could reduce costs to £100/MWh by 2020. Yet these auction results suggest a far steeper decline in offshore costs.
Of course, it is always worth peering behind the headlines to put numbers in context. The sums quoted are 2012 prices. The actual figure in today’s money is therefore £64/MWh; a still subsidy-rich 50 per cent above the current wholesale price of about £40.
The real question though is how the industry can support such a reduction. Take overall costs, for instance. Most studies do not yet point to projects breaking even at £57.50. According to a recent review by the UK’s Offshore Wind Programme Board, so-called levelised costs for new wind projects at the point of commitment (ie not yet built, but button decisively pressed) declined by 7 per cent annually from £142/MWh in 2010-11 to just £97 in 2015-16, driven by factors such as the use of larger turbines and better siting. But while these are impressive figures even they cannot explain a further £40 drop in such a short space of time.
What’s more, by far the biggest component of those costs is capital expenditure, and another study suggests that progress here is much more nuanced. A new report led by Gordon Hughes, a former professor of economics at Edinburgh University, and published by the sceptical Global Warming Policy Foundation, has analysed the reported capital costs of 86 projects across Europe. These show that while technological advances are driving down costs by 4 per cent annually, this gain is being offset as the industry moves out into deeper and more challenging waters. So, depending on where future projects are sited, there may even be no clear downward trend at all.
It may be possible that the auction-winning projects have specific reasons for being able to deliver low prices. For instance, the Hornsea II project sponsored by Denmark’s Dong Energy sits next to a first farm that is also being built by the same company (at far higher rates of subsidy), offering the opportunity to share support infrastructure, as well as the link between the turbines and the grid.
But it is also possible that the promoters view the CFD contract as a pretty loose commitment. “Potentially these bids could be seen as more of an option on future capacity,” said Allan Baker, Société Générale’s global head of power advisory and project finance at Bloomberg’s New Energy Finance Summit last week.
Just three giant wind farms have taken all the capacity in the current auction, which at 3.2GW is equivalent to 60 per cent of Britain’s current offshore fleet. That means the competition is in effect shut out.
The contracts do not represent an absolute commitment. According to the UK government, the developers could withdraw were they unable to obtain financing, with only a limited penalty. What they would mainly lose was the right to pop the same project into a later auction round.
So to the extent, for instance, that contracts depend on yet-to-be developed technologies, such as 15MW turbines, or squeezing contractor prices, there would be little cost to cancelling were developers not to get the deals they hoped for.
And even beyond construction, the CFD could conceivably be revoked by the operator were it prepared to pay a significant, not ruinous, financial penalty, Prof Hughes reckons. So should wholesale prices rise well above the level of the fixed strike price in future, developers might be able to flip across and benefit from (superior) market rates. That might happen, for instance, were the government to introduce a higher carbon price.

Subsidy-Free Wind Farms Risk Ruining the Industry’s Reputation
Subsidy-Free Wind Farms Risk Ruining the Industry’s Reputation. By Jess Shankleman
Bloomberg,
https://www.bloomberg.com/news/articles/2017-09-19/subsidy-free-wind-farms-risk-ruined-reputations-for-industry
That’s the warning of industry executives, who are cautious about the future of zero-subsidy offshore wind farms planned in Germany this year. Developers led by Energie Baden-Wuerttemberg AG and Dong Energy A/S are betting they can sell the electricity they produce from the wind farms at a profit without any help from taxpayers.
“The offshore wind industry needs to be careful,” Irene Rummelhoff, executive vice president at Statoil ASA’s New Energy Solutions unit, said at the Bloomberg New Energy Finance Summit in London on Tuesday. “They’re taking on these options, and when you get to the delivery date, if they’re not able to build the projects, it will ruin the reputation of the industry.”
The German government may not have the right rules in place to ensure developers actually deliver on their winning bids, said Thomas Karst, senior vice president at MHI Vestas Offshore Wind AS.
“The regulatory power lies with the owners of the concessions and they may or may not get built, so that model from the regulatory point of view doesn’t really work,” Karst said at the same conference.
Winning bidders in the German auctions based business cases on giant wind turbines, soaring as high as The Shard in London and generating as much as 15 megawatts of power each. Those machines haven’t been built yet and aren’t due until the next decade.
“The question is are they actually deliverable? Potentially these bids could be seen as more of an option on future capacity,” said Allan Baker, global head of power advisory and project finance at Societe Generale SA.

Spanish farm produce supplier reduces human workers from 500 to 100 using robots. David Edwards. Robotics & Automation News, September 19, 2017, www.roboticsandautomationnews.com/2017/09/19/spanish-farm-produce-supplier-reduces-human-workers-from-500-to-100-using-robots/14148/
Spanish farm produce supplier El Dulze has reduced its human workforce from 500 down to just 100 with the use of robots, according to a report on FruitNet.com.
The company is said to be using Fanuc robots – LR Mate 200iB models – which use vision systems to even out the production line so the vegetables are not bunched up too close together for packing.
The robots also appear to be picking heads of lettuce and placing them in containers, or plastic packaging.
A total of 68 robots have been installed at the El Dulze facility in Murcia, and they process approximately 550,000 heads of lettuce every day.
The robotic system is also said to have reduced rejects from 20 per cent to 5 per cent, mostly due to improvements in hygiene and handling.
Managing director José Sánchez is quoted by FruitNet.com as saying: “This business has traditionally been labour intensive but today labour is increasingly unavailable.
“This region has a major shortage of labour – many workers in the industry are immigrants but this hasn’t solved our problem.
“As minimal skill is needed we have a real problem with labour and turnover of these workers is high – they just seem to come and go.
“Reducing the amount of people has made everything more hygienic and damage to the lettuces caused by handling is now minimal.”

Perverse Consequences of Well Intentioned Regulation: Evidence from India's Child Labor Ban
Perverse Consequences of Well Intentioned Regulation: Evidence from India's Child Labor Ban. Prashant Bharadwaj, Leah K. Lakdawala, and Nicholas Li. https://ideas.repec.org/p/nbr/nberwo/19602.html
ABSTRACT: While bans against child labor are a common policy tool, there is very little empirical evidence validating their effectiveness. In this paper, we examine the consequences of India’s landmark legislation against child labor, the Child Labor (Prohibition and Regulation) Act of 1986. Using data from employment surveys conducted before and after the ban, and using age restrictions that determined who the ban applied to, we show that child wages decrease and child labor increases after the ban. These results are consistent with a theoretical model building on the seminal work of Basu and Van (1998) and Basu (2005), where families use child labor to reach subsistence constraints and where child wages decrease in response to bans, leading poor families to utilize more child labor. The increase in child labor comes at the expense of reduced school enrollment. We also examine the effects of the ban at the household level. Using linked consumption and expenditure vdata, we find that along various margins of household expenditure, consumption, calorie intake and asset holdings, households are worse off after the ban.

Abstract: The deterrence hypothesis predicts that the introduction of a penalty that leaves everything else unchanged will reduce the occurrence of the behavior subject to the fine. We present the result of a field study in a group of day‐care centers that contradicts this prediction. Parents used to arrive late to collect their children, forcing a teacher to stay after closing time. We introduced a monetary fine for late‐coming parents. As a result, the number of late‐coming parents increased significantly. After the fine was removed no reduction occurred. We argue that penalties are usually introduced into an incomplete contract, social or private. They may change the information that agents have, and therefore the effect on behavior may be opposite of that expected. If this is true, the deterrence hypothesis loses its predictive strength, since the clause “everything else is left unchanged” might be hard to satisfy.
---
In a day-care center for little children... The contract signed at the beginning of the year states that the day-care center operates between 0730 and 1600. There is no mention of what happens if parents come late to pick up their children. In particular, before the beginning of the study, there was no fine for coming late. When parents did not come on time, one of the teachers had to wait with the children concerned. Teachers would rotate in this task, which is considered part of the job of a teacher, a fact that is clearly explained when a teacher is hired. Parents rarely came after 1630. [...] At the beginning of the fifth week [of 20 weeks in the study], we introduced a fine [of little money for each child and 10 minutes delay] in six of the 10 day-care centers,7 which had been selected randomly. [...] At the beginning of the seventeenth week, the fine was removed with no explanation.
[...] Fact 1.—The effect of introducing the fine was a significant increase in the number of late-coming parents.
Fact 2.—Removing the fine did not affect the number of late-coming parents relative to the time of the fine. In particular, this number remained higher in the treatment group than in the control group.
Fact 3.—There is no significant difference in the behavior of the test group and the control group in the initial 4 weeks, and there is no significant trend in the test group.

Highlights
• We explore the interplay of the Dark Triad, harmful online behaviors and language
• Psychopathy and male gender predict engagement in harmful online behaviors
• Facebook users with dark traits have identifiable language characteristics
• Findings are consistent with previous research using non-linguistic criteria
Abstract: The goal of this paper was to assess the connection between dark personality traits and engagement in harmful online behaviors in a sample of Russian Facebook users, and to describe the language they use in online communication. A total of 6,724 individuals participated in the study (mean age = 44.96 years, age range: 18–85 years, 77.9% — female). Data was collected via a purpose-built application, which served two purposes: administer the survey and download consenting user’s public wall posts, gender and age from the Facebook profile. The survey included questions on engagement in harmful online behaviors and the Short Dark Triad scale; 15,281 wall posts from 1,972 users were included in the dataset. These posts were subjected to morphological, lexical and semantic analyses. More than 25% of the sample reported engaging in harmful online behaviors. Males were more likely to send insulting or threatening messages and post aggressive comments; no gender differences were found for disseminating other people’s private information. Psychopathy and male gender were the unique predictors of engagement in harmful online behaviors. A number of significant correlations were found between the dark traits and numeric, lexical, morphological and semantic characteristics of the participants’ posts.

Individual differences in the effects of baby images on attitudes toward getting married
Individual differences in the effects of baby images on attitudes toward getting married. Charles G. Lord, , Christopher J. Holland, and Sarah E. Hill. Personality and Individual Differences, Volume 121, 15 January 2018, Pages 106–110, https://doi.org/10.1016/j.paid.2017.09.029
Highlights
• Women who had viewed images of smiling babies wanted to get married sooner.
• This effect occurred for both 18- to 25-year-old and 18- to 45-year-old women.
• Baby image priming increased accessibility of thoughts about having children.
• Baby image priming increased positivity of thoughts about having children.
• All of these effects occurred for women, but not for men.
Abstract: Previous research on determinants of marital and reproductive timing focused on factors prominent in evolutionary theories. We focused on complementary factors prominent in research on attitudes, social cognition, and personality. Attitude construal and situated inference theories hold that priming can increase the accessibility of specific concepts, and that valence of the primed concepts can affect subsequent judgments. In two studies, one with college students and the other with a larger, more diverse sample, women, but not men, wanted to get married sooner if they had than had not recently seen images of smiling babies. Primed women also listed a greater number of and more positive children-related thoughts about marriage. These results suggest that subtle contextual cues can alter accessibility of relevant concepts, affect attitudes even on important issues, and work differently for different individuals. The results also suggest closer links between evolutionary, social cognitive, and personality theories.

European Paradox or Delusion—Are European Science and Economy Outdated? Alonso Rodríguez-Navarro Francis Narin. Science and Public Policy, scx021, https://doi.org/10.1093/scipol/scx021
Abstract: The European Union (EU) seems to presume that the mass production of European research papers indicates that Europe is a leading scientific power, and the so-called European paradox of strong science but weak technology is due to inefficiencies in the utilization of this top level European science by European industry. We fundamentally disagree, and will show that Europe lags far behind the USA in the production of important, highly cited research. We will show that there is a consistent weakening of European science as one ascends the citation scale, with the EU almost twice as effective in the production of minimal impact papers, while the USA is at least twice as effective in the production of very highly cited scientific papers, and garnering Nobel prizes. Only in the highly multinational, collaborative fields of Physics and Clinical Medicine does the EU seem to approach the USA in top scale impact.

The Mortality and Myocardial Effects of Antidepressants Are Moderated by Preexisting Cardiovascular Disease: A Meta-Analysis
The Mortality and Myocardial Effects of Antidepressants Are Moderated by Preexisting Cardiovascular Disease: A Meta-Analysis. Maslej M.M. et al. Psychotherapy and Psychosomatics, https://doi.org/10.1159/000477940
Abstract
Background: Antidepressants (ADs) are commonly prescribed medications, but their long-term health effects are debated. ADs disrupt multiple adaptive processes regulated by evolutionarily ancient biochemicals, potentially increasing mortality. However, many ADs also have anticlotting properties that can be efficacious in treating cardiovascular disease. We conducted a meta-analysis assessing the effects of ADs on all-cause mortality and cardiovascular events in general-population and cardiovascular-patient samples.
Methods: Two reviewers independently assessed articles from PubMed, EMBASE, and Google Scholar for AD-related mortality controlling for depression and other comorbidities. From these articles, we extracted information about cardiovascular events, cardiovascular risk status, and AD class. We conducted mixed-effect meta-analyses testing sample type and AD class as moderators of all-cause mortality and new cardiovascular events.
Results: Seventeen studies met our search criteria. Sample type consistently moderated health risks. In general-population samples, AD use increased the risks of mortality (HR = 1.33, 95% CI: 1.14-1.55) and new cardiovascular events (HR = 1.14, 95% CI: 1.08-1.21). In cardiovascular patients, AD use did not significantly affect risks. AD class also moderated mortality, but the serotonin reuptake inhibitors were not significantly different from tricyclic ADs (TCAs) (HR = 1.10, 95% CI: 0.93-1.31, p = 0.27). Only “other ADs” were differentiable from TCAs (HR = 1.35, 95% CI: 1.08-1.69). Mortality risk estimates increased when we analyzed the subset of studies controlling for premedication depression, suggesting the absence of confounding by indication.
Conclusions: The results support the hypothesis that ADs are harmful in the general population but less harmful in cardiovascular patients.
Abstract
Background: Antidepressants (ADs) are commonly prescribed medications, but their long-term health effects are debated. ADs disrupt multiple adaptive processes regulated by evolutionarily ancient biochemicals, potentially increasing mortality. However, many ADs also have anticlotting properties that can be efficacious in treating cardiovascular disease. We conducted a meta-analysis assessing the effects of ADs on all-cause mortality and cardiovascular events in general-population and cardiovascular-patient samples.
Methods: Two reviewers independently assessed articles from PubMed, EMBASE, and Google Scholar for AD-related mortality controlling for depression and other comorbidities. From these articles, we extracted information about cardiovascular events, cardiovascular risk status, and AD class. We conducted mixed-effect meta-analyses testing sample type and AD class as moderators of all-cause mortality and new cardiovascular events.
Results: Seventeen studies met our search criteria. Sample type consistently moderated health risks. In general-population samples, AD use increased the risks of mortality (HR = 1.33, 95% CI: 1.14-1.55) and new cardiovascular events (HR = 1.14, 95% CI: 1.08-1.21). In cardiovascular patients, AD use did not significantly affect risks. AD class also moderated mortality, but the serotonin reuptake inhibitors were not significantly different from tricyclic ADs (TCAs) (HR = 1.10, 95% CI: 0.93-1.31, p = 0.27). Only “other ADs” were differentiable from TCAs (HR = 1.35, 95% CI: 1.08-1.69). Mortality risk estimates increased when we analyzed the subset of studies controlling for premedication depression, suggesting the absence of confounding by indication.

‘Barbie Doll Syndrome’. A case report of body dysmorphic disorder
„Das Barbie Syndrom“. Ein Fallbericht über die Körperdysmorphe Störung (=‘Barbie Doll Syndrome’. A case report of body dysmorphic disorder). Gruber, M., Jahn, R., Stolba, K. et al. Neuropsychiatr (2017). https://doi.org/10.1007/s40211-017-0241-2
Summary
Background: This case report aims to present a 37-year-old women striving to shape her body like a Barbie doll of which she has been fascinated since childhood. She could hardly tolerate any deviation from this beauty ideal. She has been admitted to the psychosomatic ward due to an eating disorder.
Methods: The ICD-10 and DSM-5 criteria were established for axis I disorders and the German version of the SCID II interview (for DSM-4) was applied for axis II disorders. Additionally, the “modified Yale-Brown Obsessive Compulsive Scale for body dysmorphic disorder” was carried out.
Results: The diagnosis of dysmorphophobia (ICD-10: F45.21) or body dysmorphic disorder (DSM-5: 300.7) and bulimia nervosa (ICD-10: F50.2; DSM-5: 307.51) was confirmed. The patient fulfilled criteria of an avoidant, depressive and histrionic personality disorder.
Psychopharmacological treatment with Fluoxetine was started and the patient participated in an intensive inpatient psychosomatic program. The body image, self-concept and the sense of shame were therapeutic key topics.
Conclusion: The present case report focuses on body dysmorphic disorder as a distinctive entity with high prevalence. Diagnostic criteria of different classification systems were contrasted and comorbidity with eating disorders was discussed. In clinical praxis, body dysmorphic disorder remains underdiagnosed, especially when cooccurring with an eating disorder. However, the correct diagnosis could be relevant for therapy planning.

approx translation: [The appearance of the patient is impressive. Her artificial style with toupled hair and artificial hair parts (Beehive hair style), a heavily painted face with a focus on the eyes, framed by the thick eyelid with the false eyelashes and the delicate, somewhat aged skin with the dark solarium-browned complexion. The physique is delicate except the large breasts.
The patient grew up with a stable twin-sister and an older sister in stable family circumstances. She describes the twin sister as her "mirror image", both had always placed great emphasis on their appearance, compared to each other and revised and criticized each other. At school, the sisters would sometimes have been teased because of their "mirror image". Furthermore she describes a great fascination for Barbie dolls, which would continue today. At the age of 17, she met her ex-husband, with whom she became engaged and had two children. After the birth of the second child had a postpartum depression with a resulting bonding disorder to the son. The patient did not seek professional help. Four years later, she describes a two-year "happy phase", which leads her back to the successful professional life (good merit as unskilled assistant). She would have received recognition and be able to face more self-respect.
[...]
The patient suffers from hard-to-correct beliefs about physical disfigurement, a disturbance of body perception ("the belly would be too fat," "the legs would be too straight," "the butt would be too shallow," "cellulite would be too strong, the skin too pale ") and forced thoughts through the constant comparison of one's own appearance with others. There are numerous body-related fears ("getting too fat," "hair could slip," the make-up could be blurred), as well as social-phobic fears ("fear of appearance and behavior affect others embarrassingly or embarrassingly" ). The patient is compulsive with food and the external appearance and invests up to three hours daily in the body care and cosmetics (camouflage) and two to three hours daily in the course of ritualized eating / vomiting. At the same time, there is also a strong reinsurance tendency with frequent glances in the mirror, selfies or queries. It shows an avoidance behavior (avoids strangers looking intently, to visit public baths, or to show herself naked).]

Fake news and post-truth pronouncements are increasingly common, also in the sciences, including the medical ones
Fake news and post-truth pronouncements in general and in early human development. Victor Grech. Early Human Development, https://doi.org/10.1016/j.earlhumdev.2017.09.017
Highlights
• Fake news and post-truth pronouncements are increasingly common.
• They are also being to science and to medicine.
• This editorial reviews this unsavoury trend.
• It also highlights recent debunking of fake truths in early human development.
• We, as scientists, must continue to uphold science's integrity and probity.
Abstract: Fake news and post-truth pronouncements are increasingly common, and are unfortunately also progressively being applied to the sciences, including the medical sciences. This editorial briefly reviews this unsavoury trend and highlights recent debunking of fake truths in early human development. Science is arguably the last metanarrative with any significant cachet in the postmodern period. We, as scientists, must strive to ensure that our work is transparent and of the highest possible standard so as to continue to uphold science's integrity and probity.

Captive gorilla apparently trying to engage zoo visitors in a joint task of retrieving food with a stick
Luef, E. M., & Heschl, A. (2017). Triadic interactions with tools in a gorilla. Animal Behavior and Cognition, 4(2), 136–145. https://doi.org/10.12966/abc.01.05.2017
Abstract - Triadic interactions are an important developmental milestone for young human infants, ultimately enabling them to acquire language. When an infant and a caregiver share attention regarding an object, the label given to the object becomes linked with the object, hence referential communication is established through which infants learn to associate words with meanings. In fact, triadic interactions are considered so crucial to human language development that their phylogenetic origins have become the focus of investigation to study the evolutionary history of language. In this paper, we report a communicative instance of a captive zoo gorilla apparently trying to engage zoo visitors in a joint task of retrieving food. The gorilla seemed to initiate a series of combined triadic interactions with different tools used as pointing devices while attempting to recruit a human for help. Even though it is a single observation event, we argue that the gorilla possessed relevant knowledge about the various purposes for which a specific tool can be used and utilized sophisticated communicative means in her interaction with humans.
