The research literature of psychology may be brought to bear on public
policy issues in three ways. First, psychology may be useful in estab
lishing procedures for determining public policy. Second, psychology m
ay be useful in formulating the structure for policy and its implement
ation. Third, the literature of psychology may be reflected in the act
ual content of public policy. There are many issues involved in making
inferences about public policy from the psychological literature. Amo
ng these issues are the generalizability of findings from basic scienc
e and problems of overadvocacy on the part of policy consultants. Rese
archers expect that inferences from the psychological literature would
lead to innovations in the policy, but the innovations themselves mus
t be evaluated.
