使用加州心理量表（CPI）对所有报告的双胞胎样本进行人格问卷调查，以检验双胞胎数据的一致性。MZ[同卵]双胞胎的尺度相关性在不同的样本中是相当一致的，而DZ[异卵]双胞胎的相关性却没有显示出如此多的一致性。MZ和DZ相关性之间的差异无法跨样本复制。抽样误差和抽样偏差被认为是导致不一致的主要原因，当考虑这些因素时，所产生的遗传力表明，外倾-内倾因素负载的CPI量表是最具遗传性的。讨论了抽样误差和抽样偏差对从相关双胞胎数据中估计遗传参数、揭示人格特质的差异遗传力以及设计未来研究的意义。
The consistency of twin data with personality questionnaires is examined using all reported twin samples which were administered the California Psychological Inventory [CPI]. The scale correlations for the MZ [monozygotic] twins are fairly consistent across different samples, while the correlations for DZ [dizygotic] twins fail to show as much consistency. Differences between MZ and DZ correlations fail to replicate across samples. Sampling error and sampling bias are proposed as the major reasons for the inconsistency, and when these factors are taken into account the resulting heritabilities suggest that the CPI scales loading on the extraversion-introversion factor are the most heritable. The implications of sampling error and sampling bias for estimating genetic parameters from correlational twin data, for uncovering differential heritability of personality traits, and for designing future research are discussed.
