Joël van der Weele

Joël van der Weele is a co-author, with Peter Schwardmann, of "Deception and self-deception" (Nature Human Behaviour, 2019). He studies motivated cognition: the idea that people do not form opinions solely from logic and evidence, and that self-interest and personal preferences also shape their views.

Key papers

Schwardmann, P., & van der Weele, J. (2019). Deception and self-deception. Nature Human Behaviour, 3(10), 1055-1061. doi:10.1038/s41562-019-0666-7.

In the paper's two experiments, with 688 participants combined, people told they could earn money by persuading a partner were more overconfident in private than a control group, and raising confidence made participants more persuasive later.

Key ideas

The institutional announcement describes his work as sitting at the intersection of economics and psychology, with motivated cognition at its centre. The 2019 paper applies that frame to a long-standing evolutionary claim. If people deceive themselves in order to persuade, an incentive to persuade should raise private confidence. The experiments found that it did.

The paper does not claim to show why a mind would work this way. It treats overconfidence as possibly adaptive, with social benefits, and reports the incentive effect on beliefs and the later effect on persuasion.
