Michal’s research focuses on individual differences in behavior, preferences, and performance. Specifically, he is interested in the mechanisms linking psychological traits (such as personality) with a broad range of organizational and social outcomes, including job performance, person-job fit, consumer preferences, and ideology, as well as the expression and recognition of psychological traits from behavioral residues, language, and facial features. Kosinski conducts his research using a range of computational methods, including machine learning, data mining, and observational studies involving millions of participants.
