Definition

  • Terry's Law holds that openly acknowledging a mistake is the first step toward correcting it — admitting error, rather than hiding it, opens the door to fixing it.

Core Idea

  • Recognizing a mistake is the beginning of solving it.
  • Hiding errors prevents correction and compounds harm.
  • A culture that allows honest admission improves faster.

How It Works

  • Mistakes are inevitable in any organization.
  • Concealing them lets the underlying problem persist and grow.
  • Naming the mistake honestly makes it possible to analyze, fix, and learn.

Usage Example

  • A manager who admits approving a payment in error promptly corrects it and adjusts the process — whereas a cover-up would have let the same mistake recur.

Famous Example

  • Example: Often illustrated by an anecdote of a manager (Bruce Harvey of Albuquerque, New Mexico) who mistakenly approved full pay for an absent employee and dealt with it openly.
  • Why it fits this rule: It shows acknowledging the error as the route to correcting it.
  • Verification status: A management teaching anecdote; specific details and the "Terry" attribution are repeated in popular sources but not well documented.

Use Cases / Situations Where It Applies

  • Building accountability and learning cultures.
  • Error correction and process improvement.
  • Leadership and trust.

When Not to Use or Common Misuse

  • Do not stop at admitting; admission must lead to correction.
  • Do not punish honesty so harshly that people hide future mistakes.
  • Do not treat repeated, uncorrected errors as acceptable just because they were admitted.

Rule Invention / Origin

  • Invented by: Attributed to "Terry" in management literature; source unverified.
  • Year of invention: Modern; not firmly dated.
  • Country / context of origin: United States (popular management literature).

Evidence / Research Basis

  • Consistent with research on psychological safety, error management, and learning organizations.
