Thus the data are consistent
with previous studies in lending support to
the counter-intuitive notion that genetic factors
account for some of the variation in social attitudes
in western, Caucasian culture.

The total contribution of genetic factors to differences
in personality and attitudes is significant and

The Virginia 30 000
data confirm the repeated findings of other twin
studies that genetic factors cannot be ignored in the
creation of social attitude differences. The consistent
difference between attitudes and personality may
point to different roles in human adaptation. The
absence of any assortment and vertical cultural
inheritance for personality may indicate that personality
is the manifestation of phylogenetically early
properties of the nervous system that predate the
evolution of the human brain. The fact that researchers
have proposed animal models for personality44 is
consistent with this view.
