Behavioural Consistency Within the Prisoner's Dilemma Game

Mixed-motive games represent situations that confront people with a conflict between cooperative and non-cooperative alternatives. Despite this common basis, recent research has shown that the consistency of people's choices across different mixed-motive games is rather low. The present research examined behavioural consistency within the same mixed-motive game, by presenting participants with a series of one-shot Prisoner's Dilemma Games. Across this set of games, payoffs were manipulated in order to intensify or weaken the conflict between self and the other party while maintaining the game's underlying structure. Our findings indicate that significant differences in choice behaviour are observed as a function of both situational (i.e. manipulations of the Prisoner's Dilemma Game's payoff structure) and personality differences (i.e. individual differences in personality and motivational traits). Moreover, our included situational variables and personality features did not interact with each other and were about equally impactful in shaping cooperation. Crucially, however, despite the significant behavioural differences across game variants, considerable consistency in choices was found as well, which suggests that the game's motivational basis reliably impacts choice behaviour in spite of situational and personality variations. We discuss implications for theorizing on mixed-motive situations and elaborate on the question how cooperation can be promoted

The Shape of Blame

For many types of behaviors, whether a specific instance of that behavior is either blame or praiseworthy depends on how much of the behavior is done or how people go about doing it. For instance, for a behavior such as “replying quickly to emails”, whether a specific reply is blame or praiseworthy will depend on the timeliness of that reply. Such behaviors lie on a continuum in which part of the continuum is praiseworthy (replying quickly) and another part of the continuum is blameworthy (replying late). As praise shifts towards blame along such behavioral continua, the resulting blame-praise curve must have a specific shape. A number of questions therefore arise. What determines the shape of that curve? And what determines “the neutral point”, i.e., the point along a behavioral continuum at which people neither blame nor praise? Seven studies explore these issues, focusing specifically on the impact of statistical information, and provide evidence for a hypothesis we call the “asymmetric frequency hypothesis.

Sensitivity to moral principles predicts both deontological and utilitarian response tendencies in sacrificial dilemmas

When facing sacrificial dilemmas in which harm maximizes outcomes, people appear sensitive to three moral principles: They are more averse to actively causing harm than passively allowing it (action principle), causing harm directly than indirectly (contact principle), and causing harm as a means than as a by-product of helping others (intention principle). Across five studies and a meta-analysis (N = 1,218), we examined whether individual differences in people’s sensitivity to these principles were related to participants’ moral preferences on sacrificial dilemmas. Interestingly, sensitivity to each of these principles was related to both elevated harm-rejection (i.e., deontological) as well as elevated outcome-maximization (i.e., utilitarian) response tendencies. Rather than increasing responses consistent with only one philosophical position, people sensitive to moral principles balanced moral concerns about causing harm and maximizing outcomes similar to people high in other measures of moral concern

Moral Conformity in Personal and Impersonal Moral Dilemmas

We will investigate whether the social group can influence the declared moral judgments and, if it does, to what extent. We plan to study moral decision making focusing on personal and impersonal moral dilemmas
