Yes, the James Watson, arguably the most significant scientist (with Francis Crick) of the 20th century: U of I cancels speech by Nobel Laureate James Watson
A decade ago, in a moment of excessive candor, Watson referred to the (statistically true) lower average IQ of black Americans. He probably had some bad experiences, but there is no shortage of less intelligent white people in the world either. Half of white Americans have below average IQs and many of them sport college degrees.
Anyway, the warnings are out there. You can be blackballed in academia, and in life, so keep your disappointing experiences with race, ethnicity, sexual orientation, etc. to yourself and to your friends like everybody does. Lie if you have to. Thus experience and facts are driven underground.
Jordan Peterson, in one of his Youtubes, said "The alternative to free speech is tyranny." In Watson's case, as in Charles Murray's case, the consequence of free speech is being blackballed which is a sort of extra-legal social tyranny with financial consequences. Watson would be a very wealthy man if not for his indiscretion.
Fast is, there are plenty enough intelligent, energetic, and competent people out there of all colors and ethnicities. Statistics do not apply to individuals or to the task at hand, but only at the macro level.
My ethnicity is dumber, statistically, than Ashkenazi Jews and East Asians. I can see that, experientially, in my life. My competitive self is disappointed, but I am ok with it now. IQ is not the most important factor in success or life happiness anyway: it's just one of several limiting factors in high-complexity work. I know my limits.
In fact, I think I have seen more people with average IQs achieve their life dreams than I have high IQ people. It's just in different areas of endeavor. Depending on the area, any of these can be life- limiting factors: IQ, social skills and social graces, solid judgement, stick-to-it-iveness, stress tolerance, self-discipline, energy and drive, integrity and loyalty, articulateness, curiosity, dutifulness - and more. IQ, like height, is a life factor which can't be improved by effort.
