Interesting. Then...I guess I'm living a dream since I'll have my MBA/Ph.D (Phar Science) completed in the next 2-3 yrs and I'm black. For some reason I remember all my past genetics professors saying this kind of datum is all cramp. Any man in science with an agenda (Bell Curve) came up with the his own numbers...given it isnt exact. Getdumb keyboard superstars know it all.
academics, and usually out perform the hometowns including whites. Sometimes environment and access play a greater role.
IQ-differences between blacks and whites are averages in large groups. Thus, it is not that relevant for you as an individual.
Most people who complete a Phd have at least 115+ in IQ, and that represents +2 standard deviations for the black population in the US (given an average of 85 and SD of 15). This means that at least 2% of the blacks in the US should be able to get a Phd (given that the 115+ requirement holds).
The IQ-gap becomes more interesting as we move upwards on the IQ-scale. 2% of whites attain an IQ score of 130+, but only 0.13% of the blacks (again assuming a mean of 85 and SD of 15). For an IQ of 145, the proportion of whites is 0.13% and for blacks 0.00317%.
This may help explain why blacks struggle to reach the highest levels of academical achievement, rarely becoming internationally known scientists. The group difference in IQ becomes more and more important at the extreme ends of the distribution.
