Significance Each problem was answered by a different group of respondents. In problem 1, people preferred option A with a rate of 74\% over option B with 26\%  . In problem 2, people preferred option D with a rate of 58\% over option C with a rate of 42\%. However, the discrepancy between the answers were surprising because the two problems were designed to have identical outcomes. The choices in problem 2 were designed to be compressed forms of the choices from the two stages of problem 1. (25\% chance to move on x 100\% = 25\%) chance to win $30 (25\% chance to move on x 80\% = 20\%) chance to win $45 
Significance Each problem was answered by a different group of respondents. In problem 1, people preferred option A with a rate of 74\% over option B with 26\% , even though the expected return of option B is higher . In problem 2, people preferred option D with a rate of 58\% over option C with a rate of 42\%. However, the discrepancy between the answers were surprising because the two problems were designed to have identical outcomes. The choices in problem 2 were designed to be compressed forms of the choices from the two stages of problem 1. (25\% chance to move on x 100\% = 25\%) chance to win $30. The same $7.50 expected return in option A and option C. (25\% chance to move on x 80\% = 20\%) chance to win $45. The same $9.00 expected return in option B and option D.
