Unfortunately again, IQ is highly predictive. It obviously clashes with the massive emphasis on merit, grit & educational attainment placed by western liberal ideology. It fundamentally shakes the very foundation of outcome based evaluation of one's protestant/puritanism, especially in American Academia.
(the deeply rooted nature of protestantism in the pro-science / anti-religion/ Academic community in the US is long discussion I would love to have at some point. I want to be clear that I do not mean it in a derogatory manner. It is an observation. Not a value judgement)
Imagine if grit, intelligence and productivity within a capitalistic system were highly predictable at birth. Then the claim to eliteness that lends these elite institutions power, will suddenly get the appearance of genetic superiority. It quickly starts sounding like old school eugenicists. They/We will become what they claim to hate.
Intelligence is an easier discussion in the east. The floor for the value you bring to society is not based on your intelligence alone. They also don't hide the brutal realities for survival/thriving in a society where you might lack vital skills from birth.
I think everyone on HN would agree that a feudal-class system determined at birth, is not a desirable outcome. As it stands now, ignoring the ground realities has led to us building exactly that. The tabooing of IQ does not serve to stop the creation of this dystopia. It serves to obscure the reality that we might already be living in it.
Razib Khan [1] writes a lot about intelligence from a genetic standpoint (He works in population genomics).
One quote of interest
General intelligence is one of the most predictive psychological measures in existence.
The chestnut of wisdom that ability to test well measures how well you take a test is true but trivial.
The implication that test measurement does not correlate with other aspects of performance is manifestly false.
Those with higher measured IQs have higher incomes, greater educational attainment, and lower crime rates
(this remains true among siblings who differ in IQ).
This is well known within psychological science,
but for various reasons has been obscured and downplayed by broader American culture.
As with the athletically gifted,
the differences in outcomes is most obvious in those who are intellectually gifted at a young age.
The chart below shows the outcomes of 259 children identified as very gifted in their early teens on the SAT:
One out of thirteen of these extremely bright children became tenured professors.
One out of thirty-three wrote a book. Nearly half obtained doctorates.
These are not average kids who simply “test well.”
There is luck in life, but the die is loaded.
Very high intelligence is no guarantee of exceptional achievement,
but it clearly changes the probabilities.
