# Self-Assessment Without a Downward Mechanism Is a Ratchet
## Claim
A review step that lets the assessed party adjust their own score in either direction moves upward on average, because only one direction has an advocate.
<!-- atomicity: 1 idea ✓ -->
## Scope & conditions
- Symmetry in the rules does not produce symmetry in outcomes when only one party is in the room.
- The fix is a second party with standing to argue down, not a stricter instruction to be honest.
- Explains zombie OKRs and grade inflation with the same mechanism.
- Applies to my own audit scoring wherever the scored party supplies the evidence.
## Evidence
From the Measure What Matters "Audacious" newsletter on Q3 OKR grading rituals.
