Research on escalation of commitment has predominantly been studied in the context of a single decision without consideration for the psychological consequences of escalating. This study sought to examine a) the extent to which people escalate their commitment to a failing course of action in a sequential decision-making task, b) confidence and anger as psychological consequences of escalation of commitment, and c) the reciprocal relationship between escalation of commitment and confidence and anger. Participants were 110 undergraduate students who completed a (...) series of investment decisions regarding a failing endeavor. Results revealed that although a high proportion of individuals escalate through all decisions, the extent to which they escalated decreased with each decision as they were less willing to invest money in the project. Furthermore, as participants escalated, confidence in one’s decision decreased and anger increased. Lastly, the analyses revealed that the relationship between escalation and confidence is reciprocal. Escalation was negatively associated with confidence, and confidence predicted escalation in the subsequent decision. These results highlight the importance of considering both the determinants and psychological consequences of escalation of commitment. (shrink)

The learning of immediate causation within a dynamic environment was examined. Participants encountered seven decision points in which they needed to choose which of three possible candidates was the cause of explosions in the environment. Each candidate was firing a weapon at random every few seconds, but only one of them produced an immediate effect. Some participants showed little learning, but most demonstrated increases in accuracy across time. On average, men showed higher accuracy and shorter latencies that were not explained (...) by differences in self-reported prior video game experience. This result suggests that prior reports of sex differences in causal choice in the game are not specific to situations involving delayed or probabilistic causal relations. (shrink)

The experience of free will has causal consequences, albeit not immediate ones. Although Wegner recognizes this, his model failed to incorporate this causal link. Is this experience central to “what makes us human”? A broad acceptance of Wegner's claim that free will is illusory has significant societal and religious consequences, therefore the threshold of evidence needs to be correspondingly high.
