A modified Monty Hall problem


We conduct a laboratory experiment using the Monty Hall problem to study how simplified examples improve learning behavior and correct irrational choices in probabilistic situations. In particular, we show that after experiencing a simplified version of the MHP (the 100-door version), subjects perform better in the MHP (the 3-door version), compared to the control group who only experienced the 3-door version. Our results suggest that simplified examples strongly induces learning.
