As in the first part, your task is to choose between gambles that give you a chance to either win or lose. If you are a winner in this part of the study, you will receive $100 plus the result of one of your chosen gambles. You must be at least 18, and you may participate only once in this part. There are 31 decisions to make.
Now, look at the first choice, No. 2, below. Suppose you are given a gift of $100, but you are required to choose one of the following gambles. Would you rather play:
A: 50 black marbles to win $50 and 50 red marbles to LOSE $50,
B: 50 white marbles to get $0 and 50 pink marbles to LOSE $10.
Urn B thus guarantees the most you can lose is $10, or you might break even. Because you received a gift of $100, B guarantees that the least you will end up with is $90 (i.e., $100 minus $10) and you might get to keep $100, whereas in A you might lose $50 and end up with only $50 (i.e., $100 minus $50). But A gives you a chance to end up with $150, since you keep the $100 and might win another $50.
To mark your choice, click the button under gamble A or B. Notice that the dot next to No. 2 will empty and fill in the button beneath to your choice. There are always 100 marbles in each urn, but the number of each color and the prizes for each color differ from trial to trial. After you have completed each choice, you can click the "Next Trial" link, which will take you to the next trial.
On Dec. 21, 2004, three
people will be selected randomly. Each
person selected for this part receive a gift of $100 plus the result of their
chosen gamble on one of the 31 choices.
One trial will be selected randomly from the 31 trials, and if you were one
of the lucky people, you will get to play the gamble you chose on the trial
selected. If the gamble you chose wins, the winnings will be added to your
$100, and if it loses, the loss will be subtracted from your $100. In any
case, you cannot lose your own money, but you might win as much as $200.
