A 2002 study's data might be tampered with
TL;DR
A new paper challenges the validity of a 2002 Psychological Science study on task performance with deadlines. The authors found major red flags in the data, raising questions about the original findings.
A new replication study in Psychological Science challenges the validity of a 2002 paper by Dan Ariely and Klaus Wertenbroch, which found that people perform better on tasks with evenly spaced deadlines. The replication authors discovered four major red flags in the original data, including identical correction numbers for 18 out of 20 participants in the 'Last Day Deadline' condition. This raises serious questions about the original study's data integrity and its influence in economics and psychology courses. The original study has over 2,100 citations, making this replication a significant development.
