Probability Size Matters: The Effect of Foreground‐Only versus Foreground+Background Graphs on Risk Aversion Diminishes with Larger Probabilities

Graphs are increasingly recommended for improving decision‐making and promoting risk‐avoidant behaviors. Graphs that depict only the number of people affected by a risk (“foreground‐only” displays) tend to increase perceived risk and risk aversion (e.g., willingness to get vaccinated), as compared to graphs that also depict the number of people at risk for harm (“foreground+background” displays). However, previous research examining these “foreground‐only effects” has focused on relatively low‐probability risks (
