Celebrated scientist attacked for race comments: "All our social policies are based on the fact that their intelligence is the same as ours - whereas all the testing says not really" By Cahal Milmo Published: 17 October 2007 One of the world's most eminent scientists was embroiled in an extraordinary row last night after he claimed that black people were less intelligent than white people and the idea that "equal powers of reason" were shared across racial groups was a delusion. James Watson, a Nobel Prize winner for his part in the unravelling of DNA who now runs one of America's leading scientific research institutions, drew widespread condemnation for comments he made ahead of his arrival in Britain today for a speaking tour at venues including the Science Museum in London. The 79-year-old geneticist reopened the explosive debate about race and science in a newspaper interview in which he said Western policies towards African countries were wrongly based on an assumption that black people were as clever as their white counterparts when "testing" suggested the contrary. He claimed genes responsible for creating differences in human intelligence could be found within a decade. The newly formed Equality and Human Rights Commission, successor to the Commission for Racial Equality, said it was studying Dr Watson's remarks " in full". Dr Watson told The Sunday Times that he was "inherently gloomy about the prospect of Africa" because "all our social policies are based on the fact that their intelligence is the same as ours - whereas all the testing says not really". He said there was a natural desire that all human beings should be equal but "people who have to deal with black employees find this not true". His views are also reflected in a book published next week, in which he writes: "There is no firm reason to anticipate that the intellectual capacities of peoples geographically separated in their evolution should prove to have evolved identically. Our wanting to reserve equal powers of reason as some universal heritage of humanity will not be enough to make it so." The furore echoes the controversy created in the 1990s by The Bell Curve, a book co-authored by the American political scientist Charles Murray, which suggested differences in IQ were genetic and discussed the implications of a racial divide in intelligence. The work was heavily criticised across the world, in particular by leading scientists who described it as a work of " scientific racism". Dr Watson arrives in Britain today for a speaking tour to publicise his latest book, Avoid Boring People: Lessons from a Life in Science. Among his first engagements is a speech to an audience at the Science Museum organised by the Dana Centre, which held a discussion last night on the history of scientific racism. Critics of Dr Watson said there should be a robust response to his views across the spheres of politics and science. Keith Vaz, the Labour chairman of the Home Affairs Select Committee, said: "It is sad to see a scientist of such achievement making such baseless, unscientific and extremely offensive comments. I am sure the scientific community will roundly reject what appear to be Dr Watson's personal prejudices. "These comments serve as a reminder of the attitudes which can still exists at the highest professional levels." The American scientist earned a place in the history of great scientific breakthroughs of the 20th century when he worked at the University of Cambridge in the 1950s and 1960s and formed part of the team which discovered the structure of DNA. He shared the 1962 Nobel Prize for medicine with his British colleague Francis Crick and New Zealand-born Maurice Wilkins.
