For this: lol.
This guy is clearly a dumbass. He might have natural intelligence, but he obviously hasn't trained a lick in research or basic critical thinking because the Koko data has been revealed to be a gigantic hoax. Dog shit zoologists virtually made up half the results, and to compare an IQ test across species like this is ridiculous since you need to alter the criteria and benchmarking to achieve a standardized result where the mean represents 100IQ (even picking the right age cohort to benchmark for this endeavour would be an impossibe and completely arbitrary task for an ape-to-human comparison).
Measuring the IQ of an untrained and uneducated immigrant from an entirely different cultural background, where he'll be standardized to the average performance of someone from a developped nation, is meaningless. IQ doesn't change but performance on an IQ test changes significantly based on your environment since it involves lingustics, math, memory tests, and spatial tests that are easy to learn.
It's the reason why IQ tests become virtually useless past a certain age and without insane controls. It's also the reason why weirdos obsessed with their own IQ can learn to kill at these tests with practice, and it's the reason why, "brain training" minigames are a hoax -- people think they're getting smarter, but they're just having short term increases in IQ performance that eventually plateaue and that are in line with the gains shown by anyone who practices the tests.
His tweet fails on every level and it's just a racist dumbass misinterpreting and fumbling with material he's too uneducated to understand; even better, he's too dumb to keep it to himself.
