Twin Studies on Personality Traits - Dictionary of Arguments
Corr I 290
Personality traits/twin studies/Munafò: Heritability of personality traits: Data from a review of the literature (Loehlin 1992)(1), selected primary studies (Jang, Livesley and Vernon 1996(2); Riemann, Angleitner and Strelau 1997(3); Waller 1999(4)) and an analysis (Loehlin 1998(5)) of previously collected data (Loehlin and Nichols 1976(6)), all of which indicate relatively consistent and substantial heritability coefficients for all major personality traits.
It is striking that these findings appear to be relatively independent of the measurement instruments used, and hold for traits drawn from Eysenck’s tripartite theory of personality and those drawn from Costa and McCrae’s ‘Big Five’ model (Bouchard and Loehlin 2001)(7). In particular, there appears to be little or no effect of shared family environment; residual variance is typically labelled as non-shared environment, but it should be noted that this term also includes gene × environment effects and measurement error.
