While most researchers who use evolutionary theory to investigate human nat
ure especially human sexuality describe themselves as "interactionists'', t
here is no clear consensus on the meaning of this term in this context. By
interactionism most people in the field mean something like, both nature an
d nurture "count'' in the development of human psychology and behavior. Nev
ertheless, the multidisciplinary nature of evolutionary psychology results
in a wide variety of interpretations of this general claim. Today, most deb
ates within evolutionary psychology about the innateness of a given behavio
ral characteristic or over its development turn as much on which conception
of "innateness'' and "interactionism'' the researcher holds as on any empi
rical data they might derive.
