This is bullshit
. Here's why:
s. Some people are smarter
than others. Some people are just plain dumb
. This is easy to see.
It is hard to measure intelligence. Example: studies show that African Americans do about 15 percent (!!!) worse on IQ tests when they are told that they are taking intelligence tests. Yep - subjective feelings about intelligence (and its value) can have drastic
effects on IQ test performance.
Insert other relevant studies that I forgot about because I was a slacker
in psych class.
The Bell Curve
is thought provoking. It is also highly questionable. Don't take it as gospel
