Using the term over-simplified was my attempt at generosity. As presently stated, your claim is entirely wrong. Intelligence is the single best predictor of job performance for all but the most narrowly-focused manual tasks, see for example Ree & Earles, Current Directions in Psychological Science vol. 1, No. 3 (Jun., 1992), pp. 86-89.

The strong claim you made in your original comment was entirely false, and I get the impression you were just speculating wildly about something you don't actually know much about.

After intelligence, Conscientiousness is probably the single best predictor of job success since it predicts even after controlling for IQ, education level, etc. (Cribbing from my usual footnote, the best starting point is the meta-analysis http://people.tamu.edu/~mbarrick/Pubs/1991_Barrick_Mount.pdf )
