Decision-Making Experiment: Choices between Gambles

This is a study of decision making in which you can gamble without risk. At the same time, your participation in this study can help scientists in the Decision Research Center learn more about how people make choices. Decide first if you want to participate. Each person can participate only once. Scroll down and look over the questionnaire. It usually takes about 5-10 minutes.

Now, look at the first choice, No. 1, below.   Would you rather play: 
        A: fifty-fifty chance of winning either $100 or $0 (nothing), 
OR
        B: fifty-fifty chance to win either $35 or $25.

Think of probability as the number of tickets in a bag containing 100 tickets, divided by 100. Gamble A has 50 tickets that say $100 and 50 that say $0, so the probability to win $100 is .50 and the probability to get $0 is .50. If someone reaches in bag A, half the time they might win $0 and half the time $100. But in this study, you only get to play a gamble once, so the prize will be either $0 or $100. Gamble B's bag has 100 tickets also, but 50 of them say $25 and 50 of them say $35. Bag B thus guarantees at least $25, but the most you can win is $35. Some will prefer A and others will prefer B. To mark your choice, click the button next to A or B. Notice that the dot next to No. 1 will empty and fill in the button next to your choice.
