What Is the Incomplete Definition Fallacy?
This fallacy uses a definition that is too narrow, too broad, or strategically biased to support a particular conclusion. By defining a term in a self-serving way, the argument rigs the outcome before the reasoning even starts.
Also known as Persuasive Definition, this is a informal fallacy — the error lies in the content or context of the argument rather than its formal structure.
How to Spot It
Example
"Success means making a lot of money." This narrow definition excludes fulfillment, relationships, health, impact, and other measures people value.
A Stronger Version
"Success means different things to different people — financial stability, meaningful work, strong relationships, personal growth, or community impact. The definition shapes the goals you pursue."
Warning Signs
- Definitions that are too narrow to capture the full concept
- Self-serving definitions designed to win an argument
- Redefining common terms to exclude counterexamples
- Strategic vagueness that shifts as needed
How to Fix It
When an argument hinges on a definition, ask: is this the standard meaning, or has it been modified to support the conclusion? Try using a more complete definition and see if the argument still works.
