Closing a 17-Year Gap: Algorithmic Detection and Empirical Prevalence of Rank Reversal in Multi-Criteria Decision Analysis
The episode discusses a paper that addresses 'rank reversal' in Multi-Criteria Decision Analysis (MCDA). Rank reversal occurs when a decision changes based on which alternatives are included. The hosts detail how the authors built tools to test this phenomenon, finding that while most methods are stable, nearly half fail the strictest consistency test (RRT3), providing a standardized way to audit MCDA methods.
