Rob Hamm is a psychologist specializing in judgment and decision making. In his work in the Clinical Decision Making Program, he studies both how medical decisions ought to be made and how they actually are made by physicians and by patients.


How decisions ought to be made:
  • Decision Analysis
  • Multiattribute Utility Analysis
  • Cost Effectiveness Analysis
  • Probabilistic Inference (Bayes' Theorem)
  • Utility-based Treatment Threshold
How decisions are made:
  • Interpretation of situations and framing of decisions
  • Judgments of probabilities
  • Judgments of value
  • Integration of multiple items of information
