My research interests are in the following areas: (1) ignorance, uncertainty, and risk assessment; (2) quantitative methods; (3) fuzzy sets and fuzzy logic; and (4) social dilemmas.

I've been working in the area of ignorance and uncertainty for a number of years. I have a background in mathematics, sociology, and psychology, so I take an inter-disciplinary approach to the study of ignorance and uncertainty. My major work is a book, Ignorance and Uncertainty: Emerging Paradigms (NY: Springer-Verlag, 1989), in which I've attempted to provide an overview of what seems to be the greatest creative ferment over uncertainty since the decade of 1650, when probability was invented. Recent works include a chapter in a book on "Agnotology," the study of the social production of ignorance, and a co-edited volume (with Gabriele Bammer) on multidisciplinary perspectives on uncertainty.

Why "ignorance"? Uncertainty is rather fashionable these days, but ignorance is a broader, more profound, and more challenging concern. My view is that we often are really dealing with ignorance even when we claim that it's uncertainty.

My interests in social psychology grew out of my background in sociology, and thereafter my work with psychologists. In the early 80's I conducted research on prosocial behaviour, and since then I have worked on topics in decision science, social dilemmas, and status characteristics theory.

My work on quantitative methods has included the development of techniques for modeling proportions (beta-regression, with Jay Verkuilen), software tools for noncentral confidence intervals, and applications of Bayesian techniques. Mine was one of the first introductory statistics textbooks in psychology to orient completely towards confidence intervals, and I wrote the Sage "little green book" on confidence intervals.

I wrote the first book published on fuzzy sets devoted to the human sciences (Fuzzy Set Analysis for the Behavioral and Social Sciences, New York: Springer-Verlag 1987), and recently I've co-authored (with Jay Verkuilen) a Sage monograph on fuzzy set theory applications in the social sciences.
