In the Tversky and Kahneman study, participants chose Program A 72% of the time, but when the program description was phrased differently, it was selected by only 22%. What obstacle to decision making did the participants experience?
This would be best explained by the framing effect. This is a type of bias in which people make decisions on subjects based on whether these are presented positively or negatively. When this happens, decision-makers place emphasis on the positive and negative connotations that accompany the descriptions rather than on the objective analysis of the information presented.
