A Replication and Extension of Three Studies Investigating Escalation of Commitment and Regret Aversion.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This article presents preregistered replications of three influential studies in the field of escalation of commitment and regret aversion. In Study 1, we found partial support for Staw's (1976) article on the effects of personal responsibility and consequences on the escalation of commitment. Study 2 failed to replicate Zeelenberg et al. (1996) article examining the role of feedback on risk preferences. The extension of study 2 found a small correlation between the tendency to experience regret and risk preferences of participants in the Safe ONLY condition. In Study 3, we failed to replicate Wong and Kwong's (2007) results that showed a causal effect of personal responsibility and regret possibility on the escalation of commitment. Moreover, study 3's extension found no support for individual differences in neuroticism on the escalation of commitment. The impact of this replication on our understanding of decision-making processes and the factors that contribute to individuals' commitment to their choices will be discussed.
