Research Statement

Michal Kosinski’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.

Research Interests

  • Individual Differences
  • Personality
  • Consumer Preferences
  • Crowdsourcing
  • Psychological Assessment
  • Ideology


Professor Kosinski received his PhD in Psychology from the University of Cambridge (UK) in 2014. He also spent a year as a Postdoctoral Scholar at the Computer Science Department at Stanford University. Kosinski’s research has had a significant impact on both academia and the industry. His findings featured in The Economist’s special report on the future of insurance (2015), inspired two TED talks, and prompted a discussion in the EU Parliament. In 2013, Kosinski was listed among the 50 most influential people in Big Data by DataIQ and IBM, while three of his papers were listed among Altmetrics’ “Top 100 Papers That Most Caught the Public Imagination” (in 2013 and 2015). Prior to entering academia, he founded a successful ITC startup and served as a brand manager for a major digital brand.
