See my Personal Homepage for full details, including downloadable versions of all my journal papers.

I grew up in South Africa and taught at the University of Cape Town and Rhodes University before joining the University of Leicester in 1970 as a lecturer.

I was promoted to Reader in 1984 and Professor in 2000. My principal research interests are in judgment and decision making, game theory and experimental games, and psychometrics. I am currently the featured author for science and technology for Oxford University Press and the Oxford English Dictionary specialist subject consultant for psychology.

My books including the bestselling Oxford Dictionary of Psychology are shown on my Amazon Author Page, and my major journal articles are listed on my Google Scholar page.


I have been carrying out research into judgment and decision making since the foundation of the Judgment and Decision Making group in what was then the Department of Psychology in 1972/73. I have held six major research council grants, an NHS grant, and numerous research grants from charities including the British Academy, the Nuffield Foundation, the Royal Society of Edinburgh, BEM Research, and especially the Leicester JDM Endowment Fund.
