The rational irrationality of human decision-making

Författare: Professor Etienne Koechlin, Directeur du Laboratoire de Neurosciences Cognitives Institut National de la Santé et de la Recherche Médicale Ecole Normale Supérieure, Paris

Värdar: Fredrik Ullén & Henrik Ehrsson


Human decision-making is often characterized as being suboptimal or irrational. In this talk, I will argue that on the basis of behavioral, neuroimaging and modeling evidence, this apparent irrationality results from the evolution of optimized brain processes to solve the computational intractability of making optimal decisions in everyday environments featuring uncertain, changing and open-ended situations. I will provide evidence that the brain implements computable  algorithmic approximations of optimal adaptive processes, which are optimized given computational constraints. Moreover, I will show that  the poor precision of brain computations governing decision-making allows to considerably reduce the complexity of underlying inferential processes in everyday environments.
