QUOTE : Wikipedia: The IQ Controversy, the Media and Public Policy<br />The role of genetics in the black-white IQ gap has been particularly controversial. The question regarding this in the survey asked "Which of the following best characterizes your opinion of the heritability of black-white differences in IQ?" Amongst the 661 returned questionnaires, 14% declined to answer the question, 24% said that there was insufficient evidence to give an answer, 1% said that the gap was "due entirely to genetic variation", 15% voted that it was "due entirely to environmental variation" and 45% said that it was a "product of genetic and environmental variation". According to Snyderman and Rothman, this contrasts greatly with the coverage of these views as represented in the media, where the reader is led to draw the conclusion that "only a few maverick 'experts' support the view that genetic variation plays a significant role in individual or group difference, while the vast majority of experts believe that such differences are purely the result of environmental factors.
