title: Distal-proximal approaches to aggression: a rejoinder to Campbell, Muncer & Bibel.
abstract: Both consistency and variability exist in behaviour. While those who focus on inter-individual differences accept that there is also intra-individual variation, the opposite appears to be less true. A time continuum of levels of explanation is offered, and a recent adoption study corroborates the heritability of aggression.
