Séminaire de Tiffany Morisseau: When accuracy matters and when it doesn’t: motivational factors of epistemic vigilance towards scientific information.

Ce séminaire sera l’occasion de passer en revue les différentes voies de recherche qui ont été explorées en psychologie cognitive concernant la consommation de fausses informations  et ses conséquences sur la confiance dans l’information scientifique.

Jeudi 11 Mars 2021


In this presentation, I start by making a quick review of the different research avenues that have been explored in cognitive psychology relative to people’s consumption of misinformation and its consequences for trust in scientific information. I then explore a complementary perspective, drawing on the idea that citizens are in fact able to question doubtful information they encounter in the media, when truth matters from their point of view. I present two hypotheses: First, that the decision-making relevance of scientific information can be small from the individual point of view. Second, that any piece of information, including scientific information, can become relevant regardless of its accuracy, when emotional and social stakes come into play. Finally, I suggest some practical implications that can be derived from these hypotheses.
