Guilt in decision making. The effect of guilt emotion on how a decision maker focuses on the problem was investigated in the Jan. 2007 issue of the Journal of Behavioral Decision Making (see Exercise 1.26, p. 24).

Immediately after the task, students were presented with a decision problem where the stated option has predomi- nantly negative features (e.g., spending money on repairing a very old car). The results (number responding in each cat- egory) are summarized in the accompanying table. Suppose one of the 171 participants is selected at random.
