摘要

Most theories of decision making are consequentialist. They presume that people evaluate prospects on the basis of potential outcomes. However, people may often conceptualize prospects in part nonconsequentially. Consider someone evaluating a new, focal prospect given an unresolved background position to which that person is already exposed. If the two are positively correlated, the individual may conceptualize the focal prospect as a bet with the individual's background position; if they are negatively correlated, the individual may conceptualize the focal prospect as a bet against the individual's background position. Because people like to be consistent, this nonconsequentialist conceptualization may induce a taste for betting with the background position. Such bets constitute risk-seeking doubling down, not risk-averse hedging. Indeed, we observe that relative to corresponding background-less choices, participants with unresolved background positions are relatively risk-seeking, favoring positively rather than negatively correlated focal prospects. They also sometimes show a simultaneous taste for both doubling down and hedging.
