Exercise 2

In one study, a group of Asian-American women were asked to take a math exam. First they were divided into two groups. Before taking the lest, individuals in the first group were asked their opinions about coed dorms while me second were asked their family history. Those who had been reminded by the questions that they were women performed worse than those who were reminded that they were Asian. How is this an example of predictably irrational behaviour?
