In 2007, Nobel Prize winning US scientist James Watson was quoted referring to research suggesting that black people were less intelligent than other races.
Although he apologised for the offence he caused, his public engagements were cancelled and he left his British speaking tour in disgrace.
Meanwhile, right wing websites hailed him as the new Galileo – a martyr to political correctness that was concealing the fact that there is indeed evidence that shows different races score differently in IQ tests. But are the tests biased? Is race really a scientific category ?
In this documentary, part of the season Race: Science’s Last Taboo, Rageh Omaar sets out to find out the truth, meeting scientists who believe the research supports the view that races can be differentiated as well as those who vehemently oppose this view.
