Lessons learned from a lifetime of applied social psychology research

I started life as an experimental social psychologist but migrated to applied social psychology research. Each time I have been involved in a major applied project I have learned things that have helped in subsequent projects. Most of the time the lesson has been about research design (e.g., you must know how the study should be done before you deal with the reality of how it has to be done). Examples of other lessons include using appropriate research technology, and the importance of program planner awareness of psychological research. In this paper I describe some of the major studies in which I was the investigator and the lesson (s) I learned from each. I also touch on the relevance of the scientist/practitioner model for the applied researcher.
