An argument is constructed in which a simplistic general rule is assumed to be more widely true, therefore an exception is ignored.
- Some X are Y.
- Therefore all X are Y. ]]
Some cats are orange. Therefore all cats are orange.
Some people who own guns are murderers, therefore all gun-owners are murderers.
Some people who drive pick-up trucks are rednecks, therefore all people who drive pick-up trucks are rednecks.
Some rich people are parasitic, swindler greed-heads. Therefore they all are thus.
This fallacy combines two mistakes:
Counterexamples are usually easy to find that disprove the simple rule.
One motivation for sweeping generalization may be a fear of more of the bad kind. So if some people of type X are bad, the arguer fears that more of the bad kind will take hold.
Sweeping generalizations are always and everywhere wrong: Including this one.
If it is already established that all X are Y, then a Sweeping Generalization is redundant. For instance, some men are taller than 3 inches, therefore all men are taller than 3 inches.
