Jane Is Trying to Decide Whether She Should Marry Jim

Jane is trying to decide whether she should marry Jim. She sits down with a piece of paper and makes a list of all the positive aspects about marrying Jim, and then a list of all the negative aspects. After looking at both lists, she can see that the good things outweigh the bad. So, she calls Jim up and says, "OK, let's set a date for the wedding!" Jane's way of making up her mind is an example of:

A) felicific calculus.
B) using "distinctiveness" information in making a decision.
C) decisional framing.
D) the contrast effect.
