Abstract: The Monty Hall dilemma (MHD) is a notorious probability problem with a counterintuitive solution. There is a strong tendency to stay with the initial choice, despite the fact that switching doubles the probability of winning. The current randomised experiment investigates whether feedback in a series of trials improves behavioural performance on the MHD and increases the level of understanding of the problem. Feedback was either conditional or non-conditional, and was given either in frequency format or in percentage format. Results show that people learn
to switch most when receiving conditional feedback in frequency format.
However, problem understanding does not improve as a consequence of receiving
feedback. Our study confirms the dissociation between behavioural performance
on the MHD, on one hand, and actual understanding of the MHD, on the other.
We discuss how this dissociation can be understood.
