How strongly do IQ and math ability correlate?

IQ and mathematical performance correlate strongly (r=0.65-0.85), among the strongest cognitive correlations observed.

What IQ components predict math success?

Logical reasoning, working memory, and processing speed are the strongest IQ components predicting mathematical achievement.

Rare but possible. Exceptional spatial reasoning or pattern recognition can produce mathematical talent without elevated overall IQ.

Math training improves mathematical skills and working memory but shows minimal transfer to broader IQ improvement.

IQ correlates moderately-to-strongly with school grades and standardized test scores, explaining 25-50% of academic performance variance.

Reading strengthens verbal and crystallized intelligence. Early literacy exposure supports IQ development throughout childhood and adolescence.
