IQ tests are more tightly limited to simple logic puzzles. The types of things having a functional IQ are useful for, Chris can generally do without trouble. He can operate software, even more complicated software. He can get around. He can follow directions. He can infer things given existing premises, etc. He's most likely around 90.
But IQ is not very useful in the real world, especially when you don't have a real job. All the things Chris fucks up in life are a result of him having shitty soft skills, like talking to people without telling them about your insane pony fantasies, or understanding the concept of other people having different perspectives than he does.
