Masked-Man Fallacy
- Filed under
- Not Enough Meaning
The charge
Masked-man fallacy is treating differences in what is known about something under one description versus another as proof they are different things.
How it operates
Human reasoning tracks labels and perspectives, not just objective identity, so knowledge about one description does not transfer cleanly to another.
Logged incidents
- Incident 01
Procurement trusts a vendor under its parent-company name but rejects the same firm after a rebrand.
- Incident 02
A hiring panel praises an anonymous portfolio and then discounts it once they learn it belongs to an internal candidate.
- Incident 03
A board assumes two customer accounts are unrelated because different teams know them by different product names.
What to watch for
Ask: Am I confusing a change in label or perspective with a change in identity?
Recommended action
Make an identity map and restate the reasoning after substituting the equivalent referent to see whether the conclusion still holds.
