Everyday I hear another report that so-and-so has a high IQ. Be it some Hollywood star, a silicon valley computer wizard, a serial killer or some crazy despot from a 3rd world country. Whatever.
Yet, I know no one who has ever taken an IQ test and I don't know of any organized systematic effort to test people. Further, if you have to go out of your way to be tested, it seems like only narcissists would take the test.
I've always just assumed test scores are being randomly assigned based on how smart a reporter thinks a subject is ... which would explain the near universal claim that Obama is a genius despite all evidence to the contrary.
IQ tests were often given by the schools. I don’t know if standardized tests today often include a formal “IQ” test anymore.
