Conspiracy believers claim to be free thinkers but (Under)Use advice like everyone else.

Conspiracy believers often claim to be critical thinkers their 'own research' instead of relying on others' testimony. In two preregistered behavioural studies conducted in the United Kingdom and Pakistan (Nparticipants = 864, Ntrials = 5408), we test whether conspiracy believers have a general tendency to discount social information (in favour of their own opinions and intuitions). We found that conspiracy mentality is not associated with social information use in text-based (Study 1) and image-based (Study 2) advice-taking tasks. Yet, we found discrepancies between self-reported and actual social information use. Conspiracy believers were more likely to report relying less on social information than actually relying less on social information in the behavioural tasks. Our results suggest that the scepticism of conspiracy believers towards epistemic authorities is unlikely to be the manifestation of a general tendency to discount social information. Conspiracy believers may be more permeable to social influence than they sometimes claim.

Individual differences in self-reported lie detection abilities.

Previous literature on lie detection abilities bears an interesting paradox. On the group level, people detect others' lies at guessing level. However, when asked to evaluate their own abilities, people report being able to detect lies (i.e., self-reported lie detection). Understanding this paradox is important because decisions which rely on credibility assessment and deception detection can have serious implications (e.g., trust in others, legal issues). In two online studies, we tested whether individual differences account for variance in self-reported lie detection abilities. We assessed personality traits (Big-Six personality traits, Dark Triad), empathy, emotional intelligence, cultural values, trust level, social desirability, and belief in one's own lie detection abilities. In both studies, mean self-reported lie detection abilities were above chance level. Then, lower out-group trust and higher social desirability levels predicted higher self-reported lie detection abilities. These results suggest that social trust and norms shape our beliefs about our own lie detection abilities.

False Rape Allegation and Regret: A Theoretical Model Based on Cognitive Dissonance.

The aim of this paper is to provide a model illustrating how regretful consensual intercourse may lead to false rape allegations (FRA). An intrapersonal perspective of regret based on cognitive dissonance is added to the interpersonal factors already mentioned in the literature. The intrapersonal perspective is discussed in terms of the reduction of a state of cognitive dissonance induced by the gap between social norms and the shamefully perceived behavior. First, we start with the review of the different motives that may lead to a FRA, insisting on regret caused by cognitive dissonance. We then develop the emergence of regret from a state of cognitive dissonance. Second, we describe the means used to build the model: a literature review, an extraction of the factors at play in regret-based FRA, a chronological structure of the various factors, as some are necessarily the source of others. We then build the model. Third, we illustrate how the model could encompass many possible and usual scenarios. Thirteen plausible scenarios were developed to show the relevance of the model. Finally, we comment and discuss the model for future research and prevention.

When psychological science fails to be heard: the lack of evidence-based arguments in a ministerial report on child sexual abuse.

One of the most debated issues in relation to child sexual abuse (CSA) is whether there should be a limitation period for prosecutions. In 2017 a French ministerial report was released proposing extension of the limitation period in part because of the sometimes long delay between the alleged events and the disclosure of the abuse. For this, the report relied on dissociative amnesia. It also advocated for the development of child victim interview protocols by victim associations. We show that dissociative amnesia is not consensual within the scientific community. Instead, we recommend scientifically reliable cognitive principles to explain the lack of memory. Moreover, interviewing techniques for children have already been designed by memory researchers to enhance recall and report of CSA, from which any uncontrolled deviation might put the child's testimony at risk. We conclude by advocating for the use of evidence-based psychology, and for co-operation between practitioners, judges and researchers.
