Open-mindedness predicts support for public health measures and disbelief in conspiracy theories during the COVID-19 pandemic. Accepted for publication Judgment and Decision Making.

Open-minded epistemic attitudes are associated with adherence to public health recommendations and protect against holding false beliefs.

Long format. Enquête sur une supercherie : le prof d’université s’est-il inventé un « Prix Nobel » ? Professeur de Lettres à l’Université Marie & Louis Pasteur de Besançon, le Montbéliardais Florent Montaclair est le lauréat 2016 de la Médaille d’or de philologie, une science qui a pour objet l’étude historique d’une langue par l’analyse critique des textes. Assimilée au Prix Nobel et à la Médaille Fields, cette récompense internationale n’a en réalité aucune existence institutionnelle. C’est un faux. La stratégie qui a été mise en place pour faire croire le contraire, et a abusé beaucoup de monde, y compris le milieu universitaire, est un singulier mélange de sophistication, d’approximation et de culot monstre.

Success in academia often has more to do with luck, patronage and the job market than “hard work”.
Good academics acknowledge this.
I worked hard, but I was in the right place at the right time on occasion. Historians far more talented than I have fallen between the cracks.

Quote: " In sum, leader-directed teaching of opaque cooperative norms would be a mutually beneficial strategy, where the costs incurred by influential teachers are, at least partly, outweighed by the long-term benefits of cultivating cooperation within the group."

"Although instrumental cultural transmission frequently occurs through both teaching and non-teaching social learning, opaque cultural information is predominantly transmitted through teaching, with relatively fewer instances of non-teaching social learning."
