Research on distributive justice has shown that people’s judgments on how to distribute resources justly are shaped by various criteria including equity, need, equality, and prior ownership. Yet, an important question remains open: do people’s judgments about justice take the power of the actors under consideration? In other words, to people deem the powerful to deserve a larger share even when their contribution, need, and prior ownership are equal? The paper addresses this question. Online, participants had to judge the just (...) distribution of resources among actors who were equal in all respects except regarding power. Results revealed that a substantial proportion of participants believed that more powerful actors deserved more resources, an effect referred to as power justification. The effect was related with social dominance orientation (SDO), indicating that high-SDO participants manifested enhanced power justification. These results were replicated in three countries, suggesting that, although cultural differences are possibly important, in most societies power justification might be a criterion advocated by some people in certain occasions. These findings can inspire research about important domains where judgments about justice and power are at play, such as about how juries deliberate and about how public opinion reacts to international conflicts.

In the social sciences, research on conspiracy theories is accumulating fast. To contribute to this research, here I introduce a computational model about the psychological processes underlying support for conspiracy theories. The proposal is that endorsement of these theories depends on three factors: prior beliefs, novel evidence, and expected consequences. Thanks to the latter, a conspiracy hypothesis might be selected because it is the costliest to reject even if it is not the best supported by evidence and by prior beliefs (...) (i.e., even if it is not the most accurate). In this way, the model implies a key role for motivated reasoning. By examining the social conditions that favour the success of conspiracy theories, the paper embeds the model, whose focus is primarily psychological, within the broader social context, and applies this analysis to probe the role of conspiracy theories within contemporary Western societies. Altogether, the paper argues that a computational outlook can contribute to elucidate the socio-psychological dynamics underlying the attractiveness of conspiracy theories. (shrink)

An influential argument is that mental processes can be explained at three different levels of analysis: the functional, algorithmic, and implementation level. Identity attribution (the process whereby an identity is attributed to another individual or to the self) has been rarely explored at the functional level. To address this, here I propose a theory of identity attribution grounded on Bayesian inference, being the latter a well-established functional perspective in cognitive science. The theory posits that an identity is inferred based on (...) observations about a target’s features, about the context, and about motivational factors. This inference can be made based upon multiple sources of observations, with prior beliefs becoming more prominent when observations are fewer in number. The theory offers an interpretation of key processes driving identity attribution, potentially providing a platform for integrating different perspectives on identity in psychology and sociology.

Inspired by recent Bayesian interpretations about the psychology underlying religion, the paper introduces a theory proposing that religious conversion is shaped by three factors: (i) novel relevant information, experienced in perceptual or in social form (e.g., following interaction with missionaries); (ii) changes in the utility (e.g., expressed in an opportunity to raise in social rank) associated with accepting a new religious creed; and (iii) prior beliefs, favouring religious faiths that, although new, still remain consistent with entrenched cultural views (resulting in (...) the phenomenon of syncretism). From the theory, a multifactorial picture of conversion emerges. Based on which factor is primarily engaged in each case, a classification of different types of conversion can be derived, with a remarkable fit with empirical literature. The theory offers a description of the processes underlying religious conversion and, highlighting the links among apparently incompatible previous views, it reconciles these views within a unifying framework.
