Two-Choice Tasks Underestimate Tripartite Relationships
CSProfKGD · x · 2026-07-16
This post relays the core finding of a new preprint: **in standard experiments, the 2-choice task might systematically underestimate the natural relationship between accuracy, confidence, and reaction time**. The research question posed by the authors is why these three variables often show only moderate correlations in common experimental tasks. In their new preprint, they further test a hypothesis—that this relationship could be influenced by the **number of options available**. In other words, rather than simply reporting "weak correlations," this study asks: **does the task design itself distort our observation of cognitive metric relationships?**
