The 5th edition of Thinking and deciding is now available. Chinese translation in progress. (Course syllabus and lecture notes.)

Some papers of possible current interest


I think that deficient thinking is a major determinants of what is wrong in the world, especially when judgments and decisions are made by governments and the citizens who support them. Of particular interest are effects of the absence of actively open-minded thinking and effects of deontological (moral) rules that depart from utilitarianism as a standard.

In addition to studying these types of thinking empirically, I try to analyze the relevant standards from a more philosophical perspective. In the empirical realm, I am also interested in methodology and data analysis.
