Abstract
Nalebuff (Journal of Economic Perspectives, 1(2), 157–63, Citation1987) proposes a puzzle and a standard solution to the mentioned puzzle based on Bayes theorem. After giving the standard solution to this problem, Professor Nalebuff asked: ‘Since many if not most individuals choose to stay with their original choice, does this suggest we should look for alternatives to Bayes rule?’ In this paper a right answer to that question is proportionated.
