Decision Experiment

Decision-Making Experiment: Choices between Gambles

This is a study of decision making, just like Exp A. The instructions are the same. Some of the choices are the same and some are different. On each trial, click the button beside the gamble you would prefer to play.

Email address: We will notify you by email if you are a winner. Country: Age: You must be over 18 years to participate. Are you Male or Female? Female OR Male Education (in years). If you are a college graduate, put 16. If you have a Ph.D., put 20. Education: Years. 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 $25 or $35. 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. For each choice below, click the button beside the gamble you would rather play. Winners will be notified by email. Void where prohibited by law. 1. Which do you choose?
