My work generally concerns how people make sense of their experiential world and justify inferences and generalizations, which I have studied and written about from the perspective of attitude and impression formation, the social psychology of rumor and gossip, interpersonal acumen and synthetic benevolence and malevolence, epistemology, ethics, and data analysis. I am also especially interested in focused data analysis in randomized experimental designs, with emphasis on k > 2 contrasts and the characteristics of different effect size indicators.
For many years, I have had the pleasure of coauthoring a writing manual for undergraduate psychology students with my wife, Mimi, and also collaborating on books, articles, and studies on research methods and data analytic procedures with my old friend, Bob Rosenthal. Since retiring from Temple University at the end of 2001, I have been mainly interested in reading, thinking, and writing about a range of issues related to research methods and data analysis, and the importance of methodological pluralism and theoretical ecumenism in behavioral and social research.
