来自芬兰双胞胎登记处的证据（例如，Rose et al., 1988）表明，如果同卵双胞胎目前同居或经常接触，那么成年同卵双胞胎（MZ）在个性上比很少接触的双胞胎更相似。Kaprio等人（1990）在后续研究中得出结论：“同卵双生子之间社会联系的变化先于（并导致）其配对内相似性的变化”（第9页）。如果是真的，这个结论具有重要的理论意义，例如，许多遗传率估计将不得不向下修正。我们引用的证据表明，相似导致接触，而不是相反。迄今为止所研究的所有性状中，双胞胎的接触频率与其绝对双内差之间的相关性较低，这表明，无论因果关系的方向如何，双内相似度与他们的接触频率之间的关系都很弱。
Evidence from the Finnish Twin Registry (e.g., Rose et al., 1988) shows that adult monozygotic (MZ) twins are more similar, within pairs, in personality if the cotwins are presently cohabiting or in frequent contact than if they are seldom in contact. Results of a follow-up study led Kaprio et al. (1990) to conclude that “changes in social contact between monozygotic cotwins precede (and causally contribute to) changes in their intrapair similarity” (p. 9). If true, this conclusion has important theoretical implications, e.g., many heritability estimates would have to be revised downward. We adduce evidence suggesting that similarity leads to contact, rather than the other way around. Low correlations between twins' frequency of contact and their absolute within-pair difference on all traits thus far studied indicates that, whichever the direction of causality, the relationship between MZ within-pair similarity and their frequency of contact is very weak.
