| Research Abstract |
Study 1 investigated the robustness of the framing effect on Asian Disease Problem in non-undergraduates. Results differed form those published by Tversky ＆ Kahneman (1981) in two respects. First, the framing effect was weak. Second, no framing effect was found in some demographic groups. These findings suggested that (a) the bias may not be as robust as has been believed, and (b) unidentified factors affect weather a framing effect is observed.
Study 2 investigated the misreporting. In this study, respondents were asked if they were in favor or opposed to 4 bills. Consequently, 15% respondents bluff when asked their opinion on things they know nothing about. These findings suggested the framing effect of question-format and the critical problem of opinion poll.
The outline of the survey is as follows. (1) Date : March, 2000. (2) Sample : 1,200 samples of the Tokyo (Japan) population over 20 years old. (3) Sampling method : Random sampling. (4) Valid sample : 722 (60.2%). (5) Survey method : Placement method (split ballot technique).
