Intuitive appraisal of options


For individual decision appraisal, there is a large literature within psychology and behavioural economics describing various informal decision making methods. Examples include methods for estimating and weighting probabilities (e.g. Tversky and Kahneman 1973; Kahneman and Tversky 1979; Weber and Hilton 1990), valuing the relative importance of outcomes (Fischhoff 1996; Viscusi, Magat, and Huber 1987; Samuelson and Zeckhauser 1988), and discounting future events (Laibson 1997; Karp 2003; Frederick, Loewenstein, and O'Donoghue 2002).
After finishing this step, you should return to the Adaptation Pathfinder's entry point.
