Estimate Kanye West's IQ
Kanye West has attracted lots of media attention for his recent comments about politics and his outrageous personality. This narcissistic, highly confident, and creative personality doesn't seem to be anything new based on interviews and anecdotes of him. Given that Kanye is Black, the starting assumption that all estimates should be regressed to is 85.
GPA
Kanye reportedly got As and Bs in high-school, which corresponds to a GPA of ~3.5, compared to the mean of high-schoolers in that time of ~2.79. The SD of GPA in the NLSY is .8, which translates to a z-score of .88.
Claimed score of 133
I don’t trust Kanye’s self-reported IQ personally, given his predisposition to mania. This is not random information though; the correlation between self-reported IQ and IQ is .3.
Wealth
Kanye has a net worth of 400 Million, putting him somewhere between the top 25490 and 2668 most wealthy people in the world, which translates to a z-score of roughly 4.74.
Currently assiming correlation between GPA/self-viewed IQ/wealth and IQ of 0.6/0.3/0.2.
Unfortunately, simulations are hard to make here. I’ll just have to generate simulations for the average and SD of IQ of a Black person with a wealth z-score of 4.74, then regress that to his claimed score, then his GPA.
the mean and SD after accounting for wealth is -0.18 and 0.95
after accounting for self-claim it’s 0.4 and 0.9
after accounting for GPA it’s 0.73 and 0.73
Simulation ends with an estimate of 111 and a fairly high standard error (11)
