Slippery Slope

Fallacy Summary: Claim a small step will trigger extreme results.

Verification questions

  • Which premise is doing the critical work, and is it actually supported?
  • Does the conclusion logically follow, or does rhetoric bridge the gap?
  • What alternative explanation would still fit the observed facts?
