Individual Differences in Antisocial Punishment in Public Goods Situations: The Interplay of Cortisol with Testosterone and Dominance

This research investigates which endocrinological and psychological factors are associated with individuals' tendency to engage in destructive antisocial punishment, that is, to costly punish cooperative individuals in public goods situations. In this work, we focus on the interplay of endogenous cortisol with testosterone and dominance. We applied the dual‐hormone hypothesis according to which testosterone is positively associated with destructive and dominant behavior but only in individuals with low levels of cortisol. Study 1 shows that individuals are more likely to engage in destructive antisocial punishment in a public goods game with the option to punish when their testosterone level is high, given that their level of cortisol is low, which bolsters the dual‐hormone hypothesis. In contrast, no significant interaction effect of testosterone and cortisol emerges for the punishment of uncooperative free‐riders (altruistic punishment). In a second study, we build on these findings and document that self‐reported dominance is only positively associated with antisocial punishment (but not with altruistic punishment) when cortisol is low. In sum, the results indicate the importance of taking endocrinological and psychological factors (and their interactions) into account in order to reach a comprehensive understanding of individuals' behavior in social dilemma situations.

Set-Point Theory and Societal Collapse: The Case of Russia

Can a society’s overall level of happiness change? Until recently, it was widely held that happiness fluctuates around set-points, so that neither individuals nor societies can lastingly increase their happiness. However, data from surveys carried out in Russia from 1982 to 2011 show that happiness fell substantially following the collapse of the Soviet Union, and has begun to rise again only recently. Additional data sources, including suicide rates and indices of negative affect expression, confirm these shifts. Contrary to set-point theory, we find that the recent increase has been driven as much by generational replacement as by mean reversion among individuals. The collapse of communism led to a permanent drop in subjective wellbeing among mid-life cohorts that was subsequently never fully recovered. Happiness can be substantially and permanently impacted by life-events, including those affecting society as a whole, and societal-level happiness can rise or fall over time as a result.     

Soul searching on the wings of my wheels: Motorcyclists’ happiness

This study aimed to investigate how personal characteristics of motorcyclists influenced their affect and sense of happiness with their motorcycles. Data on personal characteristics, motorcycle characteristics, feelings about owning a motorcycle, discreet emotions, and overall happiness were collected from 367 motorcyclists attending the annual charity run event (female = 29%, male = 71%, average age ranged between 40 and 49). Results, following Structural Equation Modelling, indicated male and younger motorcyclists to experience higher discreet positive emotions compared to females and those with a preference for outdoors lifestyle. Male motorcyclists reported being happier, overall, with their motorcycles compared to female motorcyclists. Amongst males, those reporting to be self-employed and with a social life involving drinking places, tended to report higher discreet negative emotions than other male motorcyclists. Lifestyle characteristics of motorcyclists appear to have a direct effect on their overall happiness.     

Sex differences in jealousy: the (lack of) influence of researcher theoretical perspective

The sex difference in jealousy is an effect that has generated significant controversy in the academic literature (resulting in two meta-analyses that reached different conclusions on the presence or absence of the effect). In this study, we had a team of researchers from different theoretical perspectives use identical protocols to test whether the sex difference in jealousy would occur across many different samples (while testing whether mate value would moderate the effect). In our samples, we found the sex difference in jealousy to occur using both forced choice and continuous measures, this effect appeared in several different settings, and, we found that mate value moderated participant responses. The results are discussed in light of the controversy surrounding the presence of the effect.     

Interpolation in 16-Valued Trilattice Logics

In a recent paper we have defined an analytic tableau calculus \({{\mathbf {\mathsf{{PL}}}}}_{\mathbf {16}}\) for a functionally complete extension of Shramko and Wansing’s logic based on the trilattice \({SIXTEEN}_3\). This calculus makes it possible to define syntactic entailment relations that capture central semantic relations of the logic—such as the relations Open image in new window , Open image in new window , and Open image in new window that each correspond to a lattice order in \({SIXTEEN}_3\); and Open image in new window , the intersection of Open image in new window and Open image in new window . It turns out that our method of characterising these semantic relations—as intersections of auxiliary relations that can be captured with the help of a single calculus—lends itself well to proving interpolation. All entailment relations just mentioned have the interpolation property, not only when they are defined with respect to a functionally complete language, but also in a range of cases where less expressive languages are considered. For example, we will show that Open image in new window , when restricted to \(\mathcal {L}_{tf}\), the language originally considered by Shramko and Wansing, enjoys interpolation. This answers a question that was recently posed by M. Takano.     

Ernest Gellner's Words and Things: A Case Study of Empirical Philosophy

This article considers how Ernest Gellner used sociology and anthropology to attack ordinary language philosophy in Words and Things. It argues that this attack can be seen as a part of the movement to make philosophy more empirical or “naturalized,” something that has not been generally noted. It also discusses what general lessons to draw from Words and Things regarding how empirical knowledge should be used in philosophy. Among other things, the article argues that one important lesson is that empirical philosophers should make more use of “soft” social sciences, such as sociology and anthropology, and not focus exclusively on “harder” disciplines, such as physics and experimental psychology. Another upshot of the discussion is that philosophers should draw on empirical knowledge not only when they solve problems but also when they formulate them.     

When immigrant groups “misbehave”: The influence of perceived deviant behavior on increased threat and discriminatory intentions and the moderating role of right‐wing authoritarianism

In two studies, we tested the relationship between non‐immigrant individuals' perceptions of deviant behavior carried out by Muslims and foreigners and discriminatory intentions towards these outgroups. Based on a longitudinal and a representative cross‐sectional sample, we showed that two different types of perceived deviant behavior (Study 1, Muslims' unwillingness to integrate; and Study 2, foreigners' hostility towards the non‐immigrant majority group) are related to increased intergroup threat, which in turn is related to increased intentions to show passive discrimination (i.e., avoidance) towards these outgroups. In line with theorizing about an increased sensitivity for threat in authoritarian individuals, the relationship between perceptions of deviant behavior and threat was especially strong among high authoritarian individuals. Theoretical and practical implications of our results are discussed.
