 Neil Stewart


I study judgement and decision making and the application of this research to real-world choices.

I am currently using the eye movements people make while they make decisions to test models of risky, strategic, and multiattribute choice. I am continuing to develop a mathematical model of choice called decision by sampling, and am extending the model to multiattribute and risky choices. I am also using a mixture of laboratory and on-line experiments, which thus far indicate that concepts like risk aversion are not properties of the individual but are rather properties of the experiment or choice environment.

In my applied work I am continuing research to understand how defaults and anchors influence people's financial decisions using a mixture of laboratory experiments and big real-world data sets.
