An enactivist account of the dynamics of lying

https://doi.org/10.1177/10597123231166421

Kronsted, Christian; Gallagher, Shaun; Tollefsen, Deborah; Windsor, Leah (April 2023, Adaptive Behavior)

Enactivist accounts of communication have focused almost exclusively on honest, cooperative communication. However, much of human life involves deception and lies. Using the generally agreed upon definition of lying, we here develop an enactive account of the dynamics of lying. At face, lying poses a problem for enactive theories of cognition since lying seemingly requires the ability to represent counterfactual states of affairs and implant those representations in other agents' belief systems. On our account, lying involves the active manipulation of the short- and long-term dynamics of social cognitive systems so that agents have access to different sets of affordances from the one’s they counterfactually would have had access to without the lie. Representing truths and falsehoods are replaced with competency within social-cultural and material practices.
