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.

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
