Lynn (2002) reviewed the literature on psychopathy in childhood and adolescence and

found that Blacks averaged the highest rates including diagnosis with childhood conduct disorder, Attention Deficit Hyperactivity Disorder Staurosporine datasheet (ADHD), being suspended or excluded from school, scoring low on tests of moral understanding, failing to live up to financial obligations such as paying back student loans, poor work commitment, recklessness (e.g., having traffic accidents), maintaining monogamous relationships, being responsible parents, engaging in domestic violence, and needing hospitalization for injuries sustained through altercations. Rushton and Whitney (2002) analyzed the 1993–1996 INTERPOL Yearbooks and found that across 100 countries, the rate of murder, rape, and serious assault is four times higher in African and Caribbean countries than elsewhere

in the world. In violent crimes per 100,000 people, the rate for African countries was 149; for European, 42; and for Asian, 35. These results are similar to those carried out on other data sets from INTEROL and the United Nations. They show the Black overrepresentation in violent crime to be a worldwide phenomenon. In regard to sexual behavior, differences between Blacks and Whites also support the pigmentation hypothesis. In an early international survey, Ford and Beach (1951) asked married couples how often they had sex each week. Pacific Islanders and Native

Americans said from Dasatinib mouse 1 to 4 times, US Whites answered 2–4 times, while Africans Ribose-5-phosphate isomerase said 3 to over 10 times. Later surveys confirmed and extended these findings. Rushton and Bogaert, 1987 and Rushton and Bogaert, 1988 examined 41 items from the Kinsey data and found that Blacks not only had a higher rate of intercourse at an earlier age and with more partners, but also had more orgasms per act of coitus, spent more time thinking about sex, and had lower levels of sex guilt. Black females became pregnant more quickly indicated by speed of pregnancy after demobilization. Race predicted sexual behavior better than did socioeconomic status. Kinsey’s Black sample was college educated (from 1938 to 1963) and came from a middle class background (parentally intact, with high educational level) while one of the White samples was non-college educated and were lower on the same parental indices. Mixed-race (Black–White) adolescents reported an intermediate number of sexual partners compared to the two parental populations, even after controlling for socio-economic status (Rowe, 2002). The World Health Organization found the average intercourse per week for married couples in their twenties was, for American Blacks, 5; for American Whites, 4; and for the Japanese and Chinese in Asia, 2.5 (see Rushton, 2000, for a review of these studies). National surveys from Britain and the United States produce similar findings.
