In this article in Scientific America, Heather Butler (California State University/ Dominguez Hills) says the advantages of having a high I.Q. are undeniable: "Intelligent people are more likely to get better grades and go farther in school. They are more likely to be successful at work. And they are less likely to get into trouble (e.g., commit crimes) as adolescents." But Butler's family delights in pointing out times when she, a university professor, "makes really dumb mistakes."
