Salience Theory of Choice Under Risk

The Quarterly Journal of Economics / NBER · 2012

Abstract

Proposes that decision makers overweight the most salient payoffs of a lottery—those that stand out relative to the alternatives—producing context-dependent risk attitudes without any change in underlying preferences.

Methodology

A formal model in which the salience of payoff states distorts the decision weights attached to outcomes, tested against classic anomalies in decision under risk.

Findings

Salience-based weighting reproduces the Allais paradox, preference reversals, and framing effects, and predicts when people will be risk-seeking (salient upside) versus risk-averse (salient downside) as a function of the choice context.

Applied nudge

Context sets the reference point that makes an attribute salient—arrange the choice set so that the beneficial option's advantages, not its costs, are the standout feature.
