The Judgment, Decision, and Social Comparison Lab is directed by Professor Paul Windschitl and includes many graduate and undergraduate students from the Department of Psychological & Brain Sciences at the University of Iowa.  Our research topics are relevant to social psychology, cognitive psychology, and decision science. We are intrigued with issues of how people seek out, evaluate, and use information for making judgments about the future, choice options, themselves, and other people.  We seek to understand how such processes guide decisions and behavior, especially when uncertainty is involved.  Many of our studies focus on biases, their causes, and how they can be avoided.  This focus makes the research findings relevant across various domains, with a primary example being how our findings are relevant to heath-relevant issues (e.g., encouraging prevention behavior, minimizing risky behavior, making wise treatment selections).
