Video games also have potential legal advantages over IQ tests for companies. You could argue that “we only hire people good at video games to get people who fit our corporate culture of liking video games” but that argument doesn’t work as well for IQ tests.
yet again an original post title that self-sneers
video games have value and IQ tests absolutely do not
IQ tests have proven to be a good predictor of job performance, health, and likelihood of being convicted for a crime
Predicting those does have value, because it can help companies making hiring decisions and help those struggling before they start having bigger problems.
