Yet when asked whether they thought they were "good at mathematics," only 23 percent of Koreans said "yes," compared to 68 percent of Americans. Self-serving bias. Self-serving bias is the tendency to overrate oneself--to be overly confident of one's knowledge, abilities, or good fortune. The American students in this study certainly don't lack "self-esteem." What they do lack is a proper sense of how little they know about mathematics. Go To Next Slide

5. Muhammad Ali [speaking in Zaire, Africa]: "There's no country as great as the smallest city in America. I mean [here in Zaire] you can't watch television. The water won't even run right.

The toilets won't flush. The roads, the cars--there's nothing as great as America. Group bias. Group bias is the tendency to think more highly of one's nation, race, school, family, or other social group than is warranted by the evidence. In saying, for example, that "there's no country as great as the smallest city in America," Ali is clearly overstating the comparative virtues of his own country, and thus is guilty of group bias.

9. Sexually active bisexual: “I’ll never get AIDS. I’m a very intuitive person. I would sense if someone had something as degenerative as the AIDS virus.” Wishful thinking.

This person is overly confident of his or her ability to know “intuitively” when a potential sexual partner has the AIDS virus.

10. Ed: My friend Dirk is a college sophomore at a state university in upstate New York. He is blonde, loves surfing, and has a very laid-back personality. Mary: I bet he’s from California. Based on your reading of this chapter, which critical thinking hindrance does Mary exhibit?

11. Ed: My friend Dirk is a college sophomore at a state university in upstate New York. He is blonde, loves surfing, and has a very laid-back personality. Mary: I bet he’s from California. Stereotyping. Having blonde hair, enjoying surfing, and having a laid-back personality are qualities people stereotypically associate with Californians--and this despite the fact that a majority of Californians are not Caucasians. But of course many people who are not from California also have these three qualities. And given that Dirk attends a state university in upstate New York, it is unlikely, in fact, that he comes from California. This is the end of the tutorial
