Professor Joowon Klusowski studies how people make numeric judgments and decisions. Specifically, Professor Klusowski utilizes experimental and observational data to explore questions with both behavioral and quantitative elements. Examples include how people estimate their probability of success; decide the quantity of a particular good or service to acquire or consume; perceive numbers expressed as percentages and multipliers; or use data and statistics to make predictions. Additionally, Professor Klusowski is interested in various topics related to human behavior research, such as choice, behavior change, emotion, and methods. Professor Klusowski's research has appeared in journals such as Nature, Management Science, and Psychological Science.
People interpret large differences in percentage as bigger than the equivalent differences in multipliers and absolute numbers — an important insight for those who have to communicate numerical change.
