It has become increasingly evident that traditional positivistic expla
nations are not adequate for the explanation of human behavior. Altern
ative explanations have arisen in recent years in response to dissatis
faction with traditional models. Social constructionism is one promine
nt alternative. The appropriateness of constructionism as a model for
psychology has yet to be sufficiently evaluated. The objective of this
paper is to propose one criterion by which explanation models in psyc
hology might be meaningfully evaluated. This criterion is the pragmati
c standard, by which a model is evaluated in terms of its potential to
allow psychology to be useful to society at large. It is argued that
one component of usefulness may be entailed in the model's capacity fo
r generativity in psychology. The concept of generativity is explored
and social constructionism is evaluated according to this criterion.
