Do these four moves (SIFT)

  1. Stop. What is this? Who’s behind it?
  2. Investigate the source. New tab → Google the site/author + about/Wikipedia.
  3. Find better coverage. Search the claim; see if quality outlets confirm/challenge it.
  4. Trace to the original. Follow quotes/links back to the study, dataset, or full context.

Fast checks

  • Author/Source: credentials, affiliation, contact?
  • Evidence: citations, data, methods; can you view the original?
  • Date: current enough for this topic (health/tech change fast)?
  • Purpose: inform vs. persuade/sell; watch loaded language & ads.

Power moves

  • Use site: searches (e.g., site:nih.gov) for reliable background.
  • Search the source + ownership, funding, or controversy.
  • Scan “About” pages and the source’s Wikipedia entry for context.
