Who Wants to Wash Away their Sins? Guilt and Shame Proneness and Behavioral Moral Cleansing Endorsement: a Pilot Study

In our pilot cross-sectional study, we aimed to explore the associations between guilt and shame proneness and moral cleansing endorsement. Our sample consisted of 484 adults (73.3% females), aged 18 and 53 (M=24.09, SD=7.32). We used a novel approach to explore moral cleansing mechanisms, i.e., a two-item scale assessing behavioral cleansing endorsement (one's agreement with the idea that people must "wash away" their immoral acts by acting in ethical ways that would "clean" their moral debt). In addition to the significant associations that we found between moral cleansing endorsement and the guilt and shame proneness dimensions (i.e., negative behavior evaluation, repair action tendencies, negative self-evaluation, and withdrawal action tendencies), results also suggested that moral cleansing endorsement was significantly predicted by overall guilt and shame proneness. More specifically, we found that higher levels of guilt and shame proneness might account for higher moral cleansing endorsement levels. We also found important associations with participants' age: our findings suggested that the higher the age, the higher the endorsement for moral actions aimed to "clean" immoral deeds. Results are discussed in relation to cultural-related factors.</p

Shadow of the Leviathan: the Role of Dominance in the Evolution of Costly Punishment

Costly ‘altruistic’ punishment, where an individual intervenes to punish someone for behaving unfairly towards another or for violating a social norm, seems to be vital for large-scale cooperation. However, due to the costs involved, the evolution of this behaviour has remained a puzzle. The thesis initially describes why punishment is costly and explains why current theories do not sufficiently explain its evolution in the context of these costs. The thesis then offers a solution to this puzzle in the form of a dominance-based theory of the evolution of punishment. The theoretical underpinnings of this theory are discussed in reference to the previous literature, specifically how a dominant position provides sufficient heterogeneity in the cost and benefits of punishment to allow the behaviour to evolve at the individual-level of selection. Across 10 studies, the thesis empirically investigates the role dominance is theorised to play in costly punishment behaviour. First, the judgements observers make about punishers are investigated. It is demonstrated that punishers are perceived as dominant but, unlike individuals who engage in other aggressive behaviours, punishers are also well liked. While successful punishers are judged to be of the highest rank in a social group, the wider social judgements of punishers are dependent on the attempt at punishment only; successful and unsuccessful punishers are seen as equally dominant and well liked, suggesting that the willingness to attempt punishment can honestly signal both dominance and ones pro-sociality. However, additional studies show that observers a) perceive subordinate punishers will face a great deal of retaliation, b) show surprise when subordinates attempt to punish, and c) expect that dominants will punish and be successful, whereas subordinates are expected to never punish. Thus, while there are reputational benefits from punishment, only dominant individuals can actually access them. Second, the effect of a dominant position on punishment behaviour is investigated. Two studies sought to simulate the greater access to resources that dominants enjoy, and demonstrate that individuals who receive more resources from group-level cooperation will punish free-riding more frequently and more severely than those who receive less resources. Moreover, individuals who are in a stable dominant position, i.e. who can continually benefit to a greater degree than others from group cooperation, punish even more frequently and severely than when individuals receive additional resources alone. The results show that individuals only punish when it is cheap for them to do so and when investment in the public good (by punishing) can produce higher future returns for them. A dominant position provides the opportunity for both of these. Further studies demonstrate that individuals at the centre of a social network, an example of a ‘real life’ informal dominant position, are more sensitive to unfairness when making punishment decisions compared to those at the periphery of a group. However, when punishment decisions are public, and there are no economic incentives to punish, individuals behave in a similar manner regardless of social position. Taken together, the results of the empirical studies support the proposed dominance-theory of costly punishment. The theoretical implications of the dominance-theory of punishment are discussed in reference to both the proximate occurrence of punishment and its evolutionary origins in dominance and dominant behaviours. The practical implications of this theory will also be discussed, specifically in regard to when and why individuals will act in defence of the public good. While further investigation is necessary, a dominance-theory of punishment explains both results of this thesis and the findings of the wider literature, and as such provides a coherent and compelling explanation for the evolution of costly punishment and its associated emotions
