Using the full siblings and their friends in the National Longitudinal Study of Adolescent Health (Add Health), we examined two possible processes of friends' similarity: selection/influence and social homogamy. For two phenotypes, delinquency and verbal intelligence (VIQ), self-reports of siblings and their friends were linked by a computer algorithm. Structural equation models were then applied to a 4 X 4 covariance matrix (siblings 1 and 2, friends of sibling 1, friends of sibling 2) for each phenotype separately. The best-fit model of delinquency included only a selection/influence process and no social homogamy process. In contrast, the best-fit model of VIQ supported a social homogamy process. Friends' resemblance in delinquency rates can be attributed to selection and/or influence. However, friends' intellectual resemblance may be due to friends' placements in ability tracks in schools and in other social contexts instead of being a result of a preference for a particular VIQ level
