"That their [fraternal twins who grew up together] IQ scores...differ significantly more than those of identical twins who didn’t even grow up in the same family suggests that heredity is more important than environment in determining IQ."

"studies have shown that the IQs of adopted children are closer to those of their biological parents than to those of their foster parents...in a family whose children are all adopted, there will be a greater variation in IQ than in a family whose children are all biological."

"Test data show that for every social and economic class, if a son has a higher IQ than his father he is likely to move up and if his IQ is lower he is likely to move down. IQ thus appears to affect social class more than the reverse."

"If the experts are in rough agreement on the heritability of IQ, and acknowledge that genes account for at least part of the IQ differences between different races, why do the media continue to distort their views?"

"After a thorough study of press stories about IQ and a series of interviews with editors, the authors conclude that the media simply write what they wish were true about IQ rather than what the experts say"

“expert community has more or less accepted such distortions as inevitable. Since their scientific findings run counter to a conventional wisdom whose supporters are quite passionate, they have accepted a tradeoff that permits them to publish their findings in..."

"...professional journals, but not for popular consumption...Under such circumstances they can continue their scientific work without the fear of being pilloried by the larger community and of being deprived of grants for research by government agencies and private foundations."

"So fully have many experts accepted this arrangement that they are angered by colleagues with whom they agree but who popularize their views and threaten their scientific work.”"

This safe haven, as we know, is under major threat currently."

"All this results in the enshrinement of a theory of equality that is agreeable but for which there is scarcely any evidence. America therefore operates according to a political view of reality that willfully ignores the opinions of the best informed."

"It is only by disregarding — even reviling — expert opinion that affirmative action, quotas, and the rest of the racial preference industry can be justified. Gruesome distortions result."

"The great irony of intelligence testing is that one of its original purposes was to get rid of subjective bias so as to distribute jobs and schooling purely on the basis of ability. It helped break down class and social divisions."

"To criticize testing because it does not produce the results one wants is like killing the messenger because he brings bad news."

"Racial preference programs have brought back precisely the arbitrary decision-making that objective testing was designed to eliminate."

"Policy makers have been greatly influenced by closed-minded editors and television producers who ignore the experts and refuse to listen to disagreeable truths."

"Affirmative action programs, which lower standards for minorities, are based on a similarly willful disregard for expert opinion. They assume that blacks are just as intelligent and hard-working as whites and that the only reason they have not achieved as much is because of..."

"America’s history of racism. Even if one were to accept this theory, most Americans think it is wrong to punish today’s whites for the presumed sins of yesterday’s whites."

"But if, as the evidence suggests, the distribution of intelligence among blacks is not the same as for whites, racial preference programs are not just unfair to whites; they are doomed to failure."
