Church attendance, educational level, and six conservatism scales were
the subject of a multivariate behavior-genetic analysis by Truett et
al. (Behav. Genet. 229 43-62, 1992), based on responses from a large s
ample of adult Australian twins. These data are here analyzed in a dif
ferent way to elicit general conservatism factors in the genetic, shar
ed environmental, and unshared environmental covariation. The general
genetic factor appears mainly to reflect intellectual sophistication;
the general environmental factors, religious affiliation. These factor
s are similar, although not identical, for men and women.
