What is it about?

In this study, we wanted to understand what are the cognitive mechanisms underlying choice repetition in human participants. To do so we reanalyzed several datasets using mathematical models of cognition. We found that, at least, two cognitive mechanisms contribute to choice repetition: confirmation bias and perseverance.

Why is it important?

Choice repetition is often irrational: we stick to one option even if it is not the right one. Understanding the cognitive mechanisms underlying this bias is important because it can shed light on human irrationality.


This study will be followed by an in-depth comparison of the putative mechanisms underlying choice repetition.
