I am interested in a range of topics broadly construed under the banner of judgment and decision making.

One strand of research examines cognitive models of multi-attribute judgment and heuristic decision making. The special issue of Judgment and Decision Making co-edited with Arndt Bröder details some of this work and provides an overview of the field. One current focus (in work with Michael Lee and Don van Ravenzwaaij) is on the application of evidence-accumulation models to multi-attribute judgment (e.g., Newell & Lee, 2011), and the development of hierarchical Bayesian methods for examining heuristic judgment (e.g., Lee & Newell, 2011; van Ravenzwaaij et al., in press).

A second strand of research focusses on choice under risk and uncertainty. We have examined a variety of topics such as the differences between experience and description based choice (e.g., Camilleri & Newell, 2011; 2013 ; see also a guest-edited (with Tim Rakow) a special issue of the Journal of Behavioral Decision Making on this topic); reasons underlying people's tendency to probability match (e.g., Newell & Rakow, 2007; Newell et al., 2013) and how this tendency is affected by competition (with current PhD student Christin Schulze - see Schulze et al., 2013). I am also examining (with PhD student Sule Guney) factors underlying ambiguity aversion (e.g. Guney & Newell, 2011)

A third strand has begun to investigate applications of judgment and decision making research to pressing societal problems such as climate change and pension planning. The paper by Newell & Pitman (2010) and the News & Links page of this site has more information on the climate change research. The project currently involves PhD students Ash Luckman and Hui Chai, Post-Doc Rachel McDonald as well collaborations with Stephan Lewandowsky, Marilynn Brewer and Brett Hayes. The pension project involves Andreas Ortmann and other colleagues at the Australian School of Business and is jointly funded by the pension provider Unisuper.
