Results from four studies show that the reliance on affect as a heuristic of judgment and decision making is more pronounced under a promotion focus than under a prevention focus. Two different manifestations of this phenomenon were observed. Studies 1–3 show that different types of affective inputs are weighted more heavily under promotion than under prevention in person-impression formation, product evaluations, and social recommendations. Study 4 additionally shows that valuations performed under promotion are more scope-insensitive—a characteristic of affect-based valuations—than valuations performed under prevention. The greater reliance on affect as a heuristic under promotion seems to arise because promotion-focused individuals tend to find affective inputs more diagnostic, not because promotion increases the reliance on peripheral information per se.
