Crone, Damien, and Neil L Levy. 2018. “Are Free Will Believers Nicer People? (four Studies Suggest Not)”. PsyArXiv. January 10. psyarxiv.com/zpj5x
Abstract: Free will is widely considered a foundational component of Western moral and legal codes, and yet current conceptions of free will are widely thought to fit uncomfortably with much research in psychology and neuroscience. Recent research investigating the consequences of laypeople’s free will beliefs (FWBs) for everyday moral behavior suggest that stronger FWBs are associated with various desirable moral characteristics (e.g., greater helpfulness, less dishonesty). These findings have sparked concern regarding the potential for moral degeneration throughout society as science promotes a view of human behavior that is widely perceived to undermine the notion of free will. We report four studies (combined N = 921) originally concerned with possible mediators and/or moderators of the abovementioned associations. Unexpectedly, we found no association between FWBs and moral behavior. Our findings suggest that the FWB – moral behavior association (and accompanying concerns regarding decreases in FWBs causing moral degeneration) may be overstated.

Face perception sources of constraint: the evolved structure of the brain; the need to optimise responses to different everyday tasks; and the statistical structure of faces in the perceiver’s environment
Faces, people and the brain: The 45th Sir Frederic Bartlett Lecture. Andrew W Young.
Quarterly Journal of Experimental Psychology, https://doi.org/10.1177/1747021817740275
Abstract: The fact that the face is a source of diverse social signals allows us to use face and person perception as a model system for asking important psychological questions about how our brains are organised. A key issue concerns whether we rely primarily on some form of generic representation of the common physical source of these social signals (the face) to interpret them, or instead create multiple representations by assigning different aspects of the task to different specialist components. Variants of the specialist components hypothesis have formed the dominant theoretical perspective on face perception for more than three decades, but despite this dominance of formally and informally expressed theories, the underlying principles and extent of any division of labour remain uncertain. Here, I discuss three important sources of constraint: first, the evolved structure of the brain; second, the need to optimise responses to different everyday tasks; and third, the statistical structure of faces in the perceiver’s environment. I show how these constraints interact to determine the underlying functional organisation of face and person perception.

Bayesian analysis of multimethod ego-depletion studies favours the null hypothesis
Etherton, J. L., Osborne, R., Stephenson, K., Grace, M., Jones, C. and De Nadai, A. (2018), Bayesian analysis of multimethod ego-depletion studies favours the null hypothesis. Br. J. Soc. Psychol.. doi:10.1111/bjso.12236
Abstract: Ego-depletion refers to the purported decrease in performance on a task requiring self-control after engaging in a previous task involving self-control, with self-control proposed to be a limited resource. Despite many published studies consistent with this hypothesis, recurrent null findings within our laboratory and indications of publication bias have called into question the validity of the depletion effect. This project used three depletion protocols involved three different depleting initial tasks followed by three different self-control tasks as dependent measures (total n = 840). For each method, effect sizes were not significantly different from zero When data were aggregated across the three different methods and examined meta-analytically, the pooled effect size was not significantly different from zero (for all priors evaluated, Hedges’ g = 0.10 with 95% credibility interval of [−0.05, 0.24]) and Bayes factors reflected strong support for the null hypothesis (Bayes factor > 25 for all priors evaluated).

Messages about brilliance undermine women's interest in educational and professional opportunities
Messages about brilliance undermine women's interest in educational and professional opportunities. Lin Bian. Journal of Experimental Social Psychology, https://doi.org/10.1016/j.jesp.2017.11.006
Abstract: Pervasive cultural stereotypes associate brilliance with men, not women. Given these stereotypes, messages suggesting that a career requires brilliance may undermine women's interest. Consistent with this hypothesis, linking success to brilliance lowered women's (but not men's) interest in a range of educational and professional opportunities introduced via hypothetical scenarios (Experiments 1–4). It also led women more than men to expect that they would feel anxious and would not belong (Experiments 2–5). These gender differences were explained in part by women's perception that they are different from the typical person in these contexts (Experiments 5 and 6). In sum, the present research reveals that certain messages—in particular, those suggesting that brilliance is essential to success—may contribute to the gender gaps that are present in many fields.
