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 orientation) influences the occurrence of this sunk cost effect. We found...

In the current paper we investigate how feedback over decision outcomes may affect future decisions. In an experimental study we demonstrate that if people receive feedback over the outcomes they obtained (``factual outcomes'') and the outcomes they would have obtained had they decided...

Research has identified loss aversion as a strong and robust phenomenon, but has also revealed some moderators affecting the magnitude of its effect on decision making. In the current article, we draw attention to the fact that even the measurement of loss aversion itself may affect its...

We present a motivational account of the impact of emotion on decision making, termed the feeling-is-for-doing approach. We first describe the psychology of emotion and argue for a need to be specific when studying emotion's impact on decision making. Next we describe what our approach entails...

Third-party punishment has recently received attention as an explanation for human altruism. Feelings of anger in response to norm violations are assumed to motivate third-party sanctions, yet there is only sparse and indirect support for this idea. We investigated the impact of both anger and...

In three studies, we examined factors that may temporarily attenuate information search. People are generally curious and dislike uncertainty, which typically encourages them to look for relevant information. Despite these strong forces that promote information search, people sometimes...

Investors, like any decision maker, feel regret when they compare the outcome of an investment with what the outcome would have been had they invested differently. We argue and show that this counterfactual comparison process is most likely to take place when the decision maker's expectations...

An insurance policy may not only affect the consequences for victims but also for perpetrators. In six experiments we find that people recommend milder punishments for perpetrators when the victim was insured, although people believe that a sentence should not depend on the victim's insurance...

In this paper we test two hypotheses regarding magical thinking about the perceived likelihood of future events. The first is that people believe that those who ``tempt fate'' by failing to take necessary precautions are more likely to suffer negative outcomes. The second is the ``protection...
