In logical arguments, making a broad claim based only on a single example is indicative of which fallacy?

The identification of making a broad claim based on a single example as a specific logical fallacy is known as hasty generalization. This fallacy occurs when a conclusion is drawn about an entire group or category based on insufficient or unrepresentative evidence. In other words, someone could encounter one instance that supports a conclusion about a larger population and prematurely generalizes that one example to the whole.

For example, if someone were to meet one rude person from a particular city and conclude that everyone from that city is rude, they’re making a hasty generalization. This reasoning is flawed because it relies on inadequate evidence—a single case—rather than a comprehensive analysis of the broader group.

Recognizing this fallacy is crucial in logical reasoning and argumentation. Ensuring claims are supported by a sufficient sample size or comprehensive data helps avoid erroneous conclusions and strengthens the validity of an argument.
