America’s elite, normally so dismissive of IQ, found themselves having to consider and publicly in the US Supreme Court (from March 3) a case brought forward from Florida to the effect that IQ 80, not 70, should be the cut-off point for deciding mental defect in criminal cases (Nature, 20 ii).

At issue here is PC (political correctness). Whenever IQ disadvantages Blacks, it is prohibited. While a cutoff at IQ 70 exempts 2 of Whites, it exempts 30% of Blacks. While it inches closer to 85, the Black average, it gets closer to exclude half of Blacks from responsibility.
Scoring low on purpose
It is very easy to run a race slower then one’s slowest speed, or to do bad on a test in school, on purpose. So scoring low on an IQ test is very easy. 2 3
An IQ score can dramatically misjudge intelligence, depending on how motivated the person is when taking the IQ test, scientists discovered.
Academic performance, level of education, job performance, criminal record and even physical health and longevity are often linked to the person’s intelligence quotient, or IQ score, which tends to suggest intelligence is primarily responsible for all these outcomes. 1
With sufficient coaching even dumb people can learn to score even dumber on IQ tests. It is important though, that no amount of effort will make you run faster then Usain Bolt, and no amount of effort (other then outright cheating) will make you score higher on IQ tests. One can pretend to be dumb or slow, but not pretend to be fast or bright.
Or can can score low just for lack of effort and motivation. Offering money for good results can increase IQ scores 4 5 6
IQ Test illegal for job entry requirements
In Griggs v. Duke Power Co. the Supreme court decided that IQ tests must not be used in job admission tests. In spite of the fact that a vast amount of research shows that IQ test is by far the best predictor of job performance. As the Bell Curve cites, the US military has tested millions of recruits for a century, and tracked the professional success of hundreds of thousands, to establish this fact.
So, for political correctness reasons, employers are deprived of the very best tool to select the best candidates for a job. Because this correctly discriminates against Blacks who indisputably have lower IQ (read our 80 posts about race and iq), this practice is prohibited. More is done to force employers to hire incompetent workers unable to do the job
A point has been made that Millions have waste money and time on unnecessary college degrees. These serve as a proxy for intelligence tests. No low-IQ person will get a degree at Stanford, though quotas may cause distortions.
IQ tests mandatory on death row
The same supreme court decided that
mentally retarded "special" people can not be fully held responsible for their crimes. 8 9 10 11 An IQ of 70 certainly is enough not to get executed, maybe 75 or 80 still are considered reason to escape death punishment
This means that 15 % to 30% of Blacks are not considered fully responsible for their crime, as US Black IQ is around 85 mean with 15 Standard Deviation.
