The information presented above suggests that African born blacks residing in western countries as a group possess IQs that are between 5 points and a full standard deviation (15 IQ points) above that of whites living in these countries. So that the median IQ for African blacks residing in the west should be about 110, if one accepts that research suggesting direct casual relationships between academic attainment levels and IQ (e.g. Gottfredson, 1998; Ostrowsky, 1999)!

Research also shows that when African Americans are matched as to linguistic behavior (e.g. black vs. standard English), literacy levels and to the comprehension of sayings requiring specific knowledge, that African Americans perform as well or better than do Whites on IQ tests.

The pineal gland is responsible for the production of melatonin, a hormone that is secreted in response to darkness, and is also the site in the brain where the highest levels of Serotonin can be found (Sun et al, 2001). In the pineal, 5-HT (Serotonin) concentration displays a remarkable diurnal pattern, with day levels much higher than night levels. Serotonin plays an important role in sleep, perception, memory, cardiovascular activity, respiratory activity, motor output, sensory and neuroendocrine function.

New research is suggesting that black skin may enhance the body’s natural immune system and provide better protection against disease than white skin. The melanin in dark skin is believed to help enhance the body’s natural ability to combat pathogens.
