Need for uniqueness motivates conspiracy beliefs

Imhoff, R., and Lamberty, P. K. (2017) Too special to be duped: Need for uniqueness motivates conspiracy beliefs. Eur. J. Soc. Psychol., doi: 10.1002/ejsp.2265
http://onlinelibrary.wiley.com/doi/10.1002/ejsp.2265/full

Abstract: Adding to the growing literature on the antecedents of conspiracy beliefs, this paper argues that a small part in motivating the endorsement of such seemingly irrational beliefs is the desire to stick out from the crowd, the need for uniqueness. Across three studies, we establish a modest but robust association between the self-attributed need for uniqueness and a general conspirational mindset (conspiracy mentality) as well as the endorsement of specific conspiracy beliefs. Following up on previous findings that people high in need for uniqueness resist majority and yield to minority influence, Study 3 experimentally shows that a fictitious conspiracy theory received more support by people high in conspiracy mentality when this theory was said to be supported by only a minority (vs. majority) of survey respondents. Together, these findings support the notion that conspiracy beliefs can be adopted as a means to attain a sense of uniqueness.

Perceived social presence reduces fact-checking

Perceived social presence reduces fact-checking. By Youjung Jun, Rachel Meng, and Gita Venkataramani Johar
Proceedings of the National Academy of Sciences    vol. 114 no. 23
DOI 10.1073/pnas.1700175114, http://www.pnas.org/content/114/23/5976.abstract

Significance: The dissemination of unverified content (e.g., “fake” news) is a societal problem with influence that can acquire tremendous reach when propagated through social networks. This article examines how evaluating information in a social context affects fact-checking behavior. Across eight experiments, people fact-checked less often when they evaluated claims in a collective (e.g., group or social media) compared with an individual setting. Inducing momentary vigilance increased the rate of fact-checking. These findings advance our understanding of whether and when people scrutinize information in social environments. In an era of rapid information diffusion, identifying the conditions under which people are less likely to verify the content that they consume is both conceptually important and practically relevant.

Abstract: Today’s media landscape affords people access to richer information than ever before, with many individuals opting to consume content through social channels rather than traditional news sources. Although people frequent social platforms for a variety of reasons, we understand little about the consequences of encountering new information in these contexts, particularly with respect to how content is scrutinized. This research tests how perceiving the presence of others (as on social media platforms) affects the way that individuals evaluate information—in particular, the extent to which they verify ambiguous claims. Eight experiments using incentivized real effort tasks found that people are less likely to fact-check statements when they feel that they are evaluating them in the presence of others compared with when they are evaluating them alone. Inducing vigilance immediately before evaluation increased fact-checking under social settings.

Call My Rep! How Unions Overcame the Free-Rider Problem

Murphy, Richard John: Call My Rep! How Unions Overcame the Free-Rider Problem (March 01, 2017). CESifo Working Paper Series No. 6362. Available at SSRN: https://ssrn.com/abstract=2941381

Abstract: This paper proposes an explanation of why union membership has been increasing in some occupations, despite the opportunity to freeride on traditional union benefits. I model membership as legal insurance whose demand increases with the perceived risk of allegations. Using media reports on allegations against teachers as shocks to perceived risk, I find for every five reports occurring in a region, teachers are 2.5 percentage points more likely to be members in the subsequent year. These effects are larger when teachers share characteristics with the news story and explain 45 percent of the growth in teacher union membership since 1992.

Increase in own state's minimum wage increases frequency with which low-wage workers commute out of the state

Cross-state differences in the minimum wage and out-of-state commuting by low-wage workers. By Terra McKinnish
Regional Science and Urban Economics, Volume 64, May 2017, Pages 137–147
https://doi.org/10.1016/j.regsciurbeco.2017.02.006
Highlights

•  The federal minimum wage hike compressed cross-border minimum wage differentials.
•  Low wage workers responded by commuting out of states that increased their minimum wage.
•  Results are consistent with a disemployment effect of minimum wage increases.

Abstract: The 2009 federal minimum wage increase, which compressed cross-state differences in the minimum wage, is used to investigate the claim that low-wage workers are attracted to commute out of state to neighboring states that have higher minimum wages. The analysis focuses on Public Use Microdata Areas (PUMAs) that experience commuting flows with one or more neighboring state. A difference-in-differences-in-differences model compares PUMAs that experienced a sizeable increase or decrease in their cross-border minimum wage differential to those that experience smaller change in the cross-border differential. Out-of-state commuting of low wage workers (less than 10 dollars an hour) is then compared to that of moderate wage workers (10–13 dollars an hour). The results suggest that an increase in own state's minimum wage, relative to neighbor's, increases the frequency with which low-wage workers commute out of the state. The analysis is replicated on the subset of PUMAs that experience commuting flows with more than one neighboring state, so that the estimates are identified entirely within PUMA. As a whole, the results suggest that low-wage workers tend to commute away from minimum wage increases rather than towards them.

Rethinking the Benefits of Youth Employment Programs: The Heterogeneous Effects of Summer Jobs

Rethinking the Benefits of Youth Employment Programs: The Heterogeneous Effects of Summer Jobs
Jonathan Davis & Sara Heller
NBER Working Paper, May 2017
http://www.nber.org/papers/w23443

Abstract: his paper reports the results of two randomized field experiments, each offering different populations of youth a supported summer job in Chicago. In both experiments, the program dramatically reduces violent-crime arrests, even after the summer. It does so without improving employment, schooling, or other types of crime; if anything, property crime increases over 2-3 post-program years. To explore mechanisms, we implement a machine learning method that predicts treatment heterogeneity using observables. The method identifies a subgroup of youth with positive employment impacts, whose characteristics differ from the disconnected youth served in most employment programs. We find that employment benefiters commit more property crime than their control counterparts, and non-benefiters also show a decline in violent crime. These results do not seem consistent with typical theory about improved human capital and better labor market opportunities creating a higher opportunity cost of crime, or even with the idea that these programs just keep youth busy. We discuss several alternative mechanisms, concluding that brief youth employment programs can generate substantively important behavioral change, but for different outcomes, different youth, and different reasons than those most often considered in the literature.

Increase in deployment & combat injuries for white and Hispanic soldiers relative to black ones & for soldiers from high-income neighborhoods relative to those from low-income ones

Who Will Fight? The All-Volunteer Army after 9/11. By Susan Payne Carter, Alexander Smith & Carl Wojtaszek
American Economic Review, May 2017, Pages 415-419
https://www.aeaweb.org/articles?id=10.1257/aer.p20171082

Abstract: Who fought the War on Terror? We find that as the wars in Iraq and Afghanistan progressed, there was an increase in the fraction of active-duty Army enlistees who were white or from high-income neighborhoods and that these two groups selected combat occupations more often. Among men, we find an increase in deployment and combat injuries for white and Hispanic soldiers relative to black soldiers and for soldiers from high-income neighborhoods relative to those from low-income neighborhoods. This finding suggests that an all-volunteer force does not compel a disproportionate number of non-white and low socio-economic men to fight America's wars.

IV.  Discussion
Today's all-volunteer force represents a diverse group of individuals serving for both patriotic and economic reasons. For those with fewer economic opportunities, a steady job may be the deciding factor in their enlistment decision; while for those with more outside options, wartime service may shape their deci- sion. Concerns over equity could arise under the  all-volunteer system if these enlistment motivations are differentially distributed across demographic groups. While we cannot uncover the distribution of these motivations, we can observe which groups bear the burden of war. Were the first sustained conflicts of the AVF.Iraq and Afghanistan..poor man.s fights.? To the contrary, during this time period it does not appear that there was an undue burden placed on blacks or individuals from low-income neighborhoods. The percentages of black and low-income enlistees decreased as fighting intensified, with these trends stopping when outside labor market opportunities diminished during the Great Recession and combat risk decreased. These trends were the same for men and women, although black women continued to be over-represented in the Army relative to the general population. Furthermore, black and low-income enlisted men were less likely than their white and high-income peers to be deployed or injured in combat. These differences are driven primarily by the military occupation an individual enters: black and low-income men were less likely to choose combat-intensive occupations than their white and high-income peers with the same eligibility.

Will the high-tech cities of the future be utterly lonely?

Will the high-tech cities of the future be utterly lonely? By Jessica Brown
The Week, April 24, 2017
http://theweek.com/articles/689527/hightech-cities-future-utterly-lonely

In Britain, more than one in eight people say they don't consider anyone a close friend, and the number of Americans who say they have no close friends has roughly tripled in recent decades. A large proportion of the lonely are young; almost two-thirds of 16- to 24-year-old Brits said they feel lonely at least some of the time, while almost a third are lonely often or all the time.


Healthy offspring from freeze-dried mouse spermatozoa held on the International Space Station for 9 months

Healthy offspring from freeze-dried mouse spermatozoa held on the International Space Station for 9 months. Sayaka Wakayama et al. Proceedings of the National Academy of Sciences, May 22 2017. http://www.pnas.org/content/early/2017/05/16/1701425114.full

Significance: Radiation on the International Space Station (ISS) is more than 100 times stronger than at the Earth’s surface, and at levels that can cause DNA damage in somatic cell nuclei. The damage to offspring caused by this irradiation in germ cells has not been examined, however. Here we preserved mouse spermatozoa on the ISS for 9 mo. Although sperm DNA was slightly damaged during space preservation, it could be repaired by the oocyte cytoplasm and did not impair the birth rate or normality of the offspring. Our results demonstrate that generating human or domestic animal offspring from space-preserved spermatozoa is a possibility, which should be useful when the “space age” arrives.

Abstract: If humans ever start to live permanently in space, assisted reproductive technology using preserved spermatozoa will be important for producing offspring; however, radiation on the International Space Station (ISS) is more than 100 times stronger than that on Earth, and irradiation causes DNA damage in cells and gametes. Here we examined the effect of space radiation on freeze-dried mouse spermatozoa held on the ISS for 9 mo at –95 °C, with launch and recovery at room temperature. DNA damage to the spermatozoa and male pronuclei was slightly increased, but the fertilization and birth rates were similar to those of controls. Next-generation sequencing showed only minor genomic differences between offspring derived from space-preserved spermatozoa and controls, and all offspring grew to adulthood and had normal fertility. Thus, we demonstrate that although space radiation can damage sperm DNA, it does not affect the production of viable offspring after at least 9 mo of storage on the ISS.

Distress disclosure, depression, life satisfaction, and cultural differences

Distress disclosure and psychological functioning among Taiwanese nationals and European Americans: The moderating roles of mindfulness and nationality.
Kahn, Jeffrey H.; Wei, Meifen; Su, Jenny C.; Han, Suejung; Strojewska, Agnes
Journal of Counseling Psychology, Vol 64(3), Apr 2017, 292-301. http://dx.doi.org/10.1037/cou0000202

Abstract: Research using Western samples shows that talking about unpleasant emotions—distress disclosure—is associated with fewer psychological symptoms and higher well-being. These benefits of distress disclosure may or may not be observed in East Asia where emotional control is valued. Instead, mindfulness may be more relevant to emotion regulation in East Asia (e.g., Taiwan). In the present study, cultural context (Taiwanese nationals vs. European Americans) and mindfulness were examined as moderators of the relation between distress disclosure and both depression symptoms and life satisfaction. A sample of 256 Taiwanese college students and a sample of 209 European American college students completed self-report measures in their native language. Moderated multiple regression analyses revealed significant interaction effects of mindfulness and distress disclosure on both depression symptoms and life satisfaction for Taiwanese participants but not for European Americans. Specifically, distress disclosure was negatively associated with depression symptoms and positively associated with life satisfaction for Taiwanese low in mindfulness but not for Taiwanese high in mindfulness. For European Americans, distress disclosure was not associated with depression symptoms but was associated with higher life satisfaction, regardless of one’s level of mindfulness. These findings suggest that the potential benefits of disclosing distress are a function of one’s cultural context as well as, for those from Taiwan, one’s mindfulness.
