The work of Daniel Kahneman and Amos Tversky has transformed the study of judgment and decision-making, and penetrated related disciplines such as economics, finance, marketing, law and medicine. In recognition of these achievements, Kahneman was awarded the Nobel Prize for Economics in 2003. This special issue presents ongoing research inspired by both Kahneman and Tversky. It covers many of the central themes � the heuristics and biases of judgment and prediction, framing effects, assessments and predictions of utility � that made their work so innovative. The specially written papers illustrate the range and depth of this work, and emphasise its continued relevance to current research.
