Which group was there no systematic program for their elimination ?
The second group of participants was presented with the choice between the following:In a group of 600 people , Program C : " 400 people will die " Program D : " there is a one - third probability that nobody will die , and a two - third probability that 600 people will die " In this decision frame , 78 percent preferred program D , with the remaining 22 percent opting for program C. Programs A and C are identical , as are programs B and D. The change in the decision frame between the two groups of participants produced a preference reversal : when the programs were presented in terms of lives saved , the participants preferred the secure program , A ( = C ) .
