Is Political Science Research Underpowered?

Episode Summary

What if most political science studies are too weak to find the effects they’re looking for? In this episode, we dig into a new paper by Vincent Arel-Bundock and colleagues that reveals a striking truth: quantitative political science is greatly underpowered. With thousands of tests analyzed, the authors show that many studies have only a one-in-ten chance of detecting real effects — and that even experts vastly overestimate the field’s strength. Arel-Bundock is Professor of Political Science at the Université de Montréal. In his new paper, he concludes that methodologists greatly overestimate the statistical power of political science research.
