Logical
Hasty Generalization
What it is
Drawing broad conclusions from a small, unrepresentative sample — assuming what's true of a few cases is true in general.
How it works
Real-world examples
- •"I know two people who had bad experiences with that airline, so they must be terrible."
- •"My grandfather smoked his whole life and lived to 95, so smoking can't be that bad."
- •Forming opinions about an entire country based on one visit to one city.
Ethical guidelines
- ●Claims about groups or categories require representative evidence, not anecdotes.
- ●Vivid personal examples are not substitutes for systematic data.
- ●Generalizations about people based on small samples often reinforce harmful stereotypes.
How to defend against it
- ►Ask about sample size: how many cases does this conclusion rest on?
- ►Look for systematic data rather than relying on memorable stories.
- ►Consider whether the examples might be exceptional rather than representative.
