| Summary: | This authoritative book shows how the gap between a group's mean IQ and achievement can be precisely measured, and then partitioned between two factors -- an important methodology with potential application for all ethnic groups. In this case, the author shows that Chinese Americans' occupational achievements are generally far beyond their IQ -- as if they had a mean IQ 21 points higher than they actually do. This unique approach to explaining group achievement emphasizes non-IQ factors such as historical origins, family, work ethic, educational tradition, personality traits, and social institutions.<br>
