乐观是遗传的吗？我们给了归因风格问卷（ASQ），乐观的措施，115个单卵双胞胎对（MZ）和27个双卵双胞胎对（DZ）。同卵双生子ASQ评分的组内相关系数为0.48（P< 0.0001），异卵双生子ASQ评分的组内相关系数为0。虽然双胞胎的样本量很小，但这些结果表明，乐观情绪可能存在很大的遗传影响。然而，我们推测，这一点以及其他复杂人格特征的传播机制可能是非常间接的。
Is optimism heritable? We gave the Attributional Style Questionnaire (ASQ), a measure of optimism, to 115 monozygotic twin pairs (MZ) and 27 dizygotic twin pairs (DZ). The intraclass correlations of the ASQ scores were 0.48 for MZ twins (P< 0.0001) and 0 for DZ twins. Though the sample size of DZ twins is small, these results suggest that there may be a substantial genetic effect on optimism. We speculate, however, that the mechanism for the transmission of this, and other complex personality traits, may be highly indirect.
