Models at Work—Models in Decision Making

Models at work--models in decision making.

In recent years, research on modeling in both the philosophy of science and the social studies of science and technology has undergone an acute transformation. Philosophers and social scientists have begun to realize that science, in the words of Carrier and Nordmann, has increasingly shifted its focus from “epistemic or truthoriented” research to “application-dominated” research. “Science is v...

Shared Mental Models & Decision-Making

The Problem: Decision-making among members of a group entails aggregating the opinions of the constituents. If the opinions are unconstrained, then concensus typically fails when any vote is taken. In contrast, when opinions reflect a shared model of the domain, then concensus is likely, assuming members can communicate accurately the reasons for their individual choices. How, then, will concen...

Models of Deferred Decision Making

Deferred decision making (DDM) refers to when an individual collects evidence about two or more risky alternatives and decides when to stop and make a final choice. Real world examples include physicians running tests before diagnosing an illness, or commanders collecting intelligence before taking military action. We conducted a DDM study aimed at investigating how people know when to defer a ...

Models of Affective Decision Making

Intuitively, how you feel about potential outcomes will determine your decisions. Indeed, an implicit assumption in one of the most influential theories in psychology, prospect theory, is that feelings govern choice. Surprisingly, however, very little is known about the rules by which feelings are transformed into decisions. Here, we specified a computational model that used feelings to predict...
