I have a PhD in Industrial/Organizational Psychology, so does that count? One can meaningfully contribute to this discussion without having a degree in psychology... a good background in statistics and research design would be sufficient. What's really at question here is the approach used to analyze the data.A: I find it enormously delightful that a bunch of people on the internet who (presumably) have done no research whatsoever as trained and experienced social psychologists are working together to determine the validity of a study in social psychology about people who don't know what they're talking about.
B: I remember hearing an interview with David Dunning some time ago where the interviewer asked, "How confident are you in the results you produced?"
He answered, "Well... I might be completely wrong, but there's no way for me to know it."
Finally, it's very common for non-psychologists (e.g., statisticians) to contribute to the design, analysis and interpretation of psychological research.
