This paper constitutes an attempt to derive the epistemological consequence
s of what is known in cognitive, developmental, and social psychology on th
e nature of naive theories. The process of cognitive development and knowle
dge acquisition is such that uncoordinated knowledge must result. There is
no process active in long-term memory to harmonize inconsistent parts. Coor
dination takes place in working memory (WM), and cognitive psychology has l
ong established its extreme exiguity. Units of explanation and domains of c
oherence are therefore small. This is, indeed, a limitation of our cognitio
n, but it is tenable pragmatically. Naive theories, on any one issue, do no
t form, psychologically, cognitively., a natural kind, These theses about h
ow our knowledge is acquired, organized, accessed, and used help to bring o
ut how one should think about naive theories. (C) 2001 Elsevier Science Ltd
