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.
