Psychological research on morality has been based on researchers' defi
nitions of morality or on philosophical theories. The present study ex
amined naturally occurring conceptions of morality by using a knowledg
e-structure methodology borrowed from cognitive psychology. Subjects g
enerated statements in response to a question designed to expose gener
ic knowledge about their concept of morality. Answer frequency and con
ceptual clustering results suggested that a variety of diverse concept
s undergirded subjects' moral thinking and revealed a person-based rat
her than a philosophy-based pattern for commonly held conceptions of m
orality. A three-dimensional scaling solution of the responses suggest
ed that conceptions of morality were characterized by individual-socia
l, general-specific, and absolute-relative distinctions. These finding
s raise questions about assumptions underlying previous theories of mo
rality. Moreover, the present methodology offers a basis for developin
g a more representative account of moral thought that depends less on
the beliefs of researchers.
