Domain-specific temporal discounting and temptation
Journal Title: Judgment and Decision Making - Year 2010, Vol 5, Issue 2
Abstract
In this investigation, we test whether temporal discounting is domain-specific (i.e., compared to other people, can an individual have a relatively high discount rate for one type of reward but a relatively low discount rate for another?), and we examine whether individual differences in the types of rewards one finds tempting explain domain-specificity in discount rates. Adults discounted delayed rewards they found particularly tempting (defined as the visceral attraction to and enjoyment of a reward) more steeply than did adults who did not find the rewards as tempting, contrary to what might be expected from the magnitude effect. Furthermore, we found significant group by domain interactions (e.g., chip lovers who do not like beer have relatively high discount rates for chips and relatively low discount rates for beer, whereas beer lovers who do not like chips showed the opposite pattern). These results suggest that domain-specificity in temptation partially accounts for corresponding domain-specificity in temporal discounting.

Who throws good money after bad? Action vs. state orientation moderates the sunk cost fallacy
The sunk cost fallacy is the tendency to continue an endeavour once an investment in money, effort, or time has been made. We studied how people’s chronic orientation to cope with failing projects (i.e., action vs. state...
Wronging past rights: The sunk cost bias distorts moral judgment
When people have invested resources into an endeavor, they typically persist in it, even when it becomes obvious that it will fail. Here we show this bias extends to people’s moral decision-making. Across two preregister...

Regret salience and accountability in the decoy effect
Two experiments examined the impact on the decoy effect of making salient the possibility of post-decision regret, a manipulation that has been shown in several earlier studies to stimulate critical examination and impro...
