• "My point was limited to correcting a misstatment of the meaning of the term heritability, nothing more."
• "Others, such as David Goldstein of Duke University, think that heritability is hiding in rare genetic variants, not common ones — in "private mutations," genetic peculiarities that are shared by just a few people each."
• "According to Gould (author of The Mismeasure of Man), the idea of heritability is confused by many: "If all environments were to become equal for everyone, heritability would rise to 100% because all remaining differences in IQ would necessarily be genetic in origin.""
