Affective decision-making (ADM) is a refutable and predictive theory of individual choice under risk and uncertainty. It generalizes expected utility theory by positing the existence of two cognitive processes – the “rational” and the “emotional” process. Observed choice is the result of their simultaneous interaction. We present a model of affective choice in insurance markets, where risk perc...

A number of recent papers have studied the environmental and genetic sources of individual di¤erences in economic and …nancial decision-making. Here we contribute to this burgeoning literature by extending it to a number of key behavioral biases that are thought to be of importance for consumption, saving and portfolio selection decisions. Using survey-based evidence from more than 11,000 Swedi...

Situated public displays are intended to convey important information to a large and heterogeneous population. Because of the heterogeneity of the population, they may risk providing a lot of irrelevant information. Many such important information items presented on public displays are actionables, items that are intended to trigger specific actions. The expected utility that such actionables h...

This paper offers a simple but powerful model of wishful thinking, cognitive dissonance, and related biases. Choices maximize subjective expected utility, but beliefs depend on the decision maker's interests as well as on relevant information. Simplifying assumptions yield a representation in which the payoff in an event affects beliefs as if it were part of the evidence about its likelihood. A...

The thesis of embodied cognition has developed as an alternative to the view that cognition is mediated, at least in part, by symbolic representations. A useful testing ground for the embodied cognition hypothesis is the representation of concepts. An embodied view of concept representation argues that concepts are represented in a modality-specific format. I argue that questions about represen...

In recent years evolutionary psychologists have developed and defended the Massive Modularity Hypothesis, which maintains that our cognitive architecture—including the part that subserves 'central processing'—is largely or perhaps even entirely composed of innate, domain-specific computational mechanisms or 'modules'. In this paper I argue for two claims. First, I show that the two main argumen...
