This book shows that Asian Americans, particularly Chinese and Japanese Americans, achieve far beyond what their mean IQ would lead us to expect.
For example, the post-war generation of Chinese Americans, those born from 1945 to 1949, had a mean IQ of 98.5 with Whites set at 100. But their achievements in terms of education, occupation, and income suggest an estimated IQ about 21 points higher than their actual IQ. This huge IQ/achievement gap partitions into a threshold factor and a capitalization factor. Chinese Americans have a lower IQ threshold for entry into higher education and high-status occupations, that is, they can gain entry with a minimum IQ 7 points lower than White Americans. Chinese Americans capitalize more effectively on their available pool of talent: 78% above the Chinese minimum actually enter high-status occupations, as opposed to only 60% of Whites, which accounts for the remaining 14 points of their IQ/achievement gap. Japanese Americans overachieve in terms of their mean IQ by about 10 points, with 3 points due to lower IQ thresholds and 7 points due to a higher capitalization rate than Whites. The preliminary data on Filipino Americans suggest a mean IQ well below Whites but achievements that have begun to approach those of Whites.
Our primary objective is to provide evidence that Asian Americans achieve far beyond the bounds of IQ. But the fact that Chinese and
