Determining Intelligence: the IQ test (Chapter 9)

In chapter nine the book discusses different measurements of intelligence and goes into depth about the IQ (intelligent quotient) test. This test can show us many things about the differences in IQ scores between groups of people. One interesting thing to know is the difference between the IQ score ranges between men and women. The bell shaped curve of men is wider than the distribution of women. This means that men have both more low and high scores for men while women have more scores in the middle.
An interesting person they talk about in the chapter is Chris Langan who has one of the highest IQ's in the United States. He once played on the television show "1 vs 100" and won $250,000. Surprisingly his job resume is not as impressive with him having worked as a bar bouncer, firefighter, and a farmer in Missouri. This is amazing that someone so smart would not be a doctor or use his intelligence to get a great academic career. He is an exception to the rule though and high IQ's tend to correlate with academic success which leads to higher income for people with higher IQ's.
