Hasty generalization is an informal fallacy of generalisation by making decisions based on too little evidence or without recognizing all of the variables. In statistics, it may mean basing broad conclusions of a survey from a small sample group.
When evidence is intentionally excluded to bias the result, it is sometimes termed the "fallacy of exclusion".
Example[change | change source]
Hasty generalization may follow this pattern
- X is true for A.
- X is true for B.
- X is true for C.
- X is true for D.
- Therefore, X is true for E, F, G, etc.
