Research

My main research program concerns decision-making in real world situations. Current work focuses on decisions for which the outcome is uncertain, such as those based on weather forecasts. One of our main research questions is whether people can understand numeric uncertainty estimates. An example is a forecast for 30% chance of winds greater than 20 mph. We have shown that people can understand this and several other kinds of uncertainty information, when it is carefully presented. Moreover such information improves decisions compared to decisions based on conventional deterministic forecasts. We are currently exploring the limits of these effects as well as uncertainty visualizations.

We are also exploring the implications of this work for other domains in which decisions are made under uncertainty (e.g. medical treatment).
