LESSON 2 · Build an Airtight Argument

Evaluating Source Quality

A blog post by an anonymous author and a peer-reviewed journal article both contain words and claims. But they occupy completely different levels of the credibility hierarchy. The anonymous blog has no accountability, no editorial process, and no verification.

This does not mean journals are always right or blogs are always wrong. It means the probability of reliability differs dramatically. Evaluating sources is about calibrating your trust based on the accountability structures behind the information.
