Deliberately seek out sources that disagree with you

For any important belief, find and read the best-regarded opposing view.

Why it works

Information search is one of the primary channels through which confirmation bias operates: people selectively expose themselves to media, people, and sources that confirm their views. Intentionally seeking opposing sources does not passively correct for this — the opposing information is still often dismissed — but it increases the sheer probability of encountering strong disconfirming evidence that even motivated reasoning cannot easily set aside.

How to do it

1. Identify your strongest current belief on a contested topic.
2. Ask: "Who is the most credible, thoughtful person who disagrees with this, and what do they actually argue?"
3. Read their primary argument, not a summarized caricature of it.
4. Ask after: "Is there anything in this that I cannot immediately refute?" If yes, update.

Evidence

Selective exposure research (Stroud, others) documents that people choose information sources that confirm existing views. Forced exposure to opposing views in controlled studies produces mixed results: sometimes it reduces bias, sometimes it produces backfire effects. (observational)

Exposure to opposing views does not reliably reduce bias and can backfire by strengthening motivated rejection; quality of engagement (reading, not dismissing) matters more than mere exposure.

Common mistake

Reading opposing sources specifically to find their weaknesses, which produces a more sophisticated version of confirmation bias rather than genuine information updating.
