Imagine that the U.S. is preparing for the outbreak of an unusual Asian disease, which is expected to kill 600 people. Two alternative programs to combat the disease have been proposed. Assume that the exact scientific estimate of the consequences of the programs are as follows:
Which of the two programs would you favor? [N = 152]
Which of the two programs would you favor? [N = 155]
Imagine that you face the following pair of concurrent decisions. First examine both decisions, then indicate the options you prefer. [N = 150]
Decision (i). Choose between:
Decision (ii). Choose between:
Choose between: [N = 86]
Each problem was presented to a different group of respondents. Each group was told that one participant in ten, preselected at random, would actually be playing for money. Chance events were realized, in the respondents’ presence, by drawing a single ball from a bag containing a known proportion of balls of the winning color, and the winners were paid immediately.
Which of the following options do you prefer? [N = 77]
Consider the following two-stage game. In the first stage, there is a 75% chance to end the game without winning anything, and a 25% chance to move into the second stage. If you reach the second stage you have a choice between: [N = 85]
Your choice must be made before the game starts, i.e., before the outcome of the first stage is known. Please indicate the option you prefer.
Which of the following options do you prefer? [N = 81]
A question dealing with the response to an epidemic. Two alternative programs have been proposed.
Which program do you prefer?
The risk to life exists only in the event (probability $.10$) that the disease is carried by a particular virus. If the disease is carried by another virus (probability $.90$), no lives are lost. If the critical virus is involved, the two programs yield:
