"The only part of the IQ test where jew exceed everyone else is verbal skills. In all other categories, they are equal to or lesser than Whites."

Back to the verbal acuity thing, that's probably the biggest thing that makes them overestimate their own intelligence, and how their outrageous arrogance manifests online. They're notorious for correcting typos in comments sections, which is a fuckwit's hobby btw, and then trashing your whole argument based on a "Gotcha!" that's basically just grade school insult misdirection. Most of them are practically imbecilic.
