Suckers in Law 
 Abstract 
The fear of being suckered is such a strong social and psychological 
phenomenon that political movements, and bodies of law, have been built 
around it. This review offers a framework for understanding how the 
psychology of feeling suckered affects legal decision-making. Feeling 
exploited or scammed is a core and widely shared aversion, and yet also a
 malleable construct, subject to framing effects and triggered (or 
untriggered) by subtle situational cues. The stakes for the sucker 
inference are high; people worried about being cheated predictably react
 by refusing to cooperate in prosocial activities, and by retaliating. 
The flight-or-fight response has deep implications for legal 
decision-making, undermining investment in cooperative enterprises, 
dispute settlement, and efficient social policy. Finally, the review 
considers the unique ambivalence toward suckers themselves—the competing
 feelings of sympathy and scorn—and how that ambivalence plays into 
underreporting of legal harms, misattributions of consent, and victim 
blaming. I conclude by suggesting that the ambivalence offers 
opportunities for productive legal interventions to reward trust.
