Epistemic vices are character traits that undermine knowledge and understanding.

The Epistemic Vice Scale is a ten-item survey to measure epistemic vice. The graph above shows that our research has demonstrated a strong relationship between your epistemic vice score and your ability to identify false conspiracy theories, misinformation about COVID-19, and fake news.

I have developed the Epistemic Vice Scale together with Boudewijn de Bruin and Mark Alfano. You find the articles developing and testing the Epistemic Vice Scale in the research section.
