The youngest of the cohort in 1979 was 14, since segregation was only officially ended in 1965, it once again seems more likely the legacy of segregation and America’s continued racist culture had a larger impact on outcomes than IQ test scores to me.
Everything in this ignores what I said in my first comment: this persists within the same racial group
Segregation explains nothing about why people of the same race would perform differently based on IQ scores when they were young.
the National Longitudinal Study of Youth doesn’t even test for IQ, this has been a waste of time.
Yes it does, it’s one of the most widely cited studies for IQ research. My uni had the class do a research project based on this study, you might just be looking at the wrong page.
The ASVAB is considered one of the accepted forms of IQ tests, as long it is proctored, like the NLSY does.
Other studies might use other IQ tests like the Wechsler Adult Intelligence Scale or Raven’s Progressive Matrices Test.
