How to ThinkIn the Age of AI

Evaluate sources by searching about them, not by reading…

Apply lateral reading by immediately opening new tabs to search for independent information about a source rather than evaluating the source by reading the source itself, because external assessment outperforms internal coherence checking.

When This Fires

  • When evaluating any new information source you haven't used before
  • When a claim seems too good, too alarming, or too convenient to be true
  • Before sharing or acting on information from an unfamiliar source
  • During any source evaluation where credibility matters for your decision

Common Failure Mode

Spending 10 minutes carefully reading an article to assess credibility, then concluding "it seems well-researched" based on internal coherence. The 10 minutes would have been better spent on 2 minutes of lateral reading: searching the author's name, the publication's reputation, and the specific claim across independent sources.

The Protocol

When evaluating a new source: (1) Do NOT start by reading the source carefully. (2) Open new tabs and search: who is the author? What is the publication's reputation? What do independent fact-checkers or domain experts say about this claim? (3) Spend 2-3 minutes on lateral assessment before deciding whether the source merits vertical reading. (4) Only if lateral reading confirms credibility → invest time reading the source vertically for content. This sequence saves time (quickly filtering unreliable sources) and improves accuracy (evaluating by external signal rather than internal presentation).
