> IQ seems to be more predictive at the low end than the high end. More complex tasks actually become more g-loaded, i.e. among very sophisticated tasks, IQ and performance are more strongly correlated than at unsophisticated tasks. The reason is presumably because unsophisticated tasks have a quick satiation in what general thinking can help at all. Though, true, a person who cannot solve simple cognitive tasks at all can very confidently be classified as someone who won't achieve much in the economy.
