Does a good social psychology paper need a path diagram? A mathematical model? A well-understood measurement procedure? A coherent, unified theory?
Corinne Moss-Racusin and I recently co-edited a special issue of JASP, and it provided an opportunity for us to share some thoughts about the role of theory in psychological science. (I've been mulling over these ideas for many years, and I weave them into my research methods courses, so I really appreciated the excuse to write about them.)
