But in the new PBS film, American Masters: Decoding Watson, he said his views on intelligence and race had not changed since. The institution also rescinded Watson's titles of Chancellor Emeritus, Oliver R. Grace Professor Emeritus and Honorary Trustee.
In 1968 Watson began serving as director of Cold Spring Harbor Laboratory, subsequently assuming the roles of president and chancellor, before being suspended and retiring from the research lab in 2007.
At the time, Watson told a magazine that he was "inherently gloomy about the prospect of Africa" as "all our social policies are based on the fact that their intelligence is the same as ours - where all the testing says not really", cited by News.sky.com.More news: Carlos Ghosn seeks bail after 2 new charges
While his hope was that everybody was equal, he added, "people who have to deal with black employees find this is not true".
Cold Spring Harbor Laboratory said it was reacting to Watson's remarks in a television documentary aired earlier this month.
The scientist, who helped identify the double-helix structure of the DNA molecule, stated in the documentary that he still held on to that view.
The Cold Spring Harbor Laboratory (CSHL), the NY facility where Dr Watson worked for almost four decades and which has a school named after him, said that it was acting in response to his remarks made in a television documentary which aired earlier this month.More news: Logan Paul Catches Heat for Saying He'll 'Go Gay' for March
He claimed the differences in intelligence between black and white people was borne out by their average scores in IQ tests.
"The statements he made in the documentary are completely and utterly incompatible with our mission, values and policies, and require the severing of any remaining vestiges of his involvement". The scientist said at the time that he made a decision to sell the award in an attempt to redeem his reputation after his comments in 2007, The New York Times reported. But in 2014, Watson auctioned off his Nobel medal for $4.1 million, after years of being shunned by the scientific community.
Watson and Crick's key evidence in their study, Photo 51, was produced by Franklin and her graduate assistant Ray Gosling at King's College London, and secured without Franklin's knowledge or authorisation via her supervisor, Maurice Wilkins.
But leading geneticists say that even modern DNA studies are now unable to validate such hypotheses about differences between human populations.More news: Oklahoma QB Austin Kendall enters transfer portal
