I have just read an interesting Swedish article on IQ, I will summarize it here. IQ, by the way, usually measures ability for language, logic and math.
1. Children with extraordinary IQ (as measured through testing) usually have strong and weak IQ abilities. For instance, they may be strong in math but weak in language. These children may sometimes be misdiagnosed with the Asperger's syndrome. 2. IQ is obviously not enough for academic success. In the 1920s, the Stanford psychologist Lewis Terman followed 1.500 children with an IQ of 150 over their lifespan. He excluded William Shockley and Luis Alvarez because they were considered to have an IQ that was too low. These two men later became nobel prize winners. 3. Men and women have equal levels of IQ (even though I have read somewhere that men have a larger variance than women). Women, however, tend to underestimate their IQ and men overestimate it. 4. The optimal manager has an IQ of 119. If his IQ is higher than that his decision making may be too complicated and he may have trouble connecting with the coworkers with lower IQ. A boss should be smart, but not too smart, that is. 5. Poets suffer more from the bipolar syndrome and depression than the average population. 6. The Flynn effect is the observed yearly increase in IQ. Every new year the performance of a year group on IQ tests is improved with 3 points on average. Therefore, IQ tests have to be restandardized annually, meaning that if a normal child born 100 years ago took the test today, he would perform on the same level as someone with mental retardation.
