A biological survey of a Cambridge suburb: assortative marriage for IQ and personality traits.
An account is given of a study, carried out in a Cambridge suburb, which measured the similarity in IQ and some personality traits between spouses. In both sexes mean IQ scores tended to diminish from social class I to V. Lower IQ scores were associated with higher levels of extraversion, neuroticism and inconsistency. Assortative marriage was found for IQ components, Total IQ, extraversion-introversion and inconsistency scores. Both geographical and social stratification were shown to affect the degree of assortative marriage.
