Abstract
The purpose of this study is to understand how people behave if they feel uncertainty over their preferences. There are no right or wrong answers in this experiment. Subjects only need to make the choice that they feel most comfortable with.
In the experiment, subjects will be able to make some money. The payment has two parts: 1) payment for each correctly answered control questions; 2) payment of one selected question. After the experiment, one question will be selected to determine the subject's payment in this part.
