Further explanation

What is happening underneath?

Changing the definition of a group to avoid counterexamples.

A counterexample appears, so the category definition gets quietly rewritten. The claim survives by excluding whatever disproves it.

01

What it sounds like

  • No real entrepreneur ever fails.
  • "No real leader asks for help." When shown strong leaders with coaches: "Well, no real real leader." Very scientific.
02

How to tell

  • The definition changes only after evidence threatens the claim.
03

Why people use it

  • It protects identity-based beliefs from messy reality.
04

How to combat it

  • Say: "What definition are we using, and did it change after the counterexample?"

Manipulation watch

How this gets used on people.

  • Groups use this to police belonging: no true member questions leadership, struggles, leaves, or asks for receipts.
