Source Evaluation

Finding Signal in Noise

We live in an unprecedented information environment. The same technology that gives us access to humanity's knowledge also enables:

  • Low-cost misinformation production
  • Viral amplification of false claims
  • Sophisticated impersonation and forgery
  • Algorithmic filter bubbles

Good epistemic hygiene starts with systematic source evaluation.

The SIFT Method

S - Stop before sharing or believing Don't let emotional reactions or urgency bypass evaluation

I - Investigate the Source

  • Who created this? What's their track record?
  • What's their incentive structure?
  • Are they an authority on this topic?

F - Find Better Coverage

  • What do other sources say?
  • Is this widely reported or isolated?
  • What's the original source?

T - Trace Claims

  • Where did this information originate?
  • Has it been altered in transmission?
  • What context might be missing?
