I'm sick of seeing retards talk about losers like Langan, Vos Savant, Rick Rosner, etc. Or really anyone who claims to have an 180 IQ or something. They all took a fraudulent test called the "Mega Test", or something similar like the "power test". It's a mail-in test, the answers have been leaked and freely available online for years, has no time limit, and the methodology of the questions is shat on by actual IQ experts. Let's start off with Langan:

>took the mega test multiple times under different pseudonyms
>never took a verified timed scientific IQ test
>is a fucking fraud
>his "theories" are complete gibberish

The Mega Test and all these supposed high IQ tests are absolute garbage. In fact so is MENSA's test, and it can be studied for. This is why MENSA is filled with pretentious idiots. The most accurate IQ test by far is the Wechsler, it is the gold standard of intelligence testing and caps out at 160 (because IQ tests are unreliable the higher you go). Not only are the Mega/Power/Mensa tests themselves fraudulent, not very g-loaded, and make careers out of idiots that have done nothing with their lives - they make normies repulsed by the actual rigorous science of IQ and REAL IQ tests that cannot like the Wechsler. "if IQ is so legit why do idiots like that Langan guy score so highly" - that's because they were not taking actual scientific IQ tests but dogshit fake tests for pseuds like the mega.

For that matter, childhood IQ tests are also garbage, because some kids develop faster than others and childhood IQ is far more fluid. IQ is <.4 heritability in childhood but .8 in adulthood. You need to test someone when they are an adult, with a real, scientific IQ test like WAIS.
