What logical fallacy involves making a generalization about a group based on the actions of one individual?

The logical fallacy that involves making a generalization about a group based on the actions or characteristics of a single individual is known as hasty generalization. This occurs when someone jumps to a conclusion about an entire group, community, or category based on insufficient or unrepresentative evidence, often drawing from just one instance or a few cases. For example, if someone observes one person from a particular city not being friendly and concludes that everyone from that city is unfriendly, that is a hasty generalization.

In contrast, the other options do not fit this definition. Faulty causation is concerned with incorrectly attributing a cause to an effect, inductive reasoning refers to a logical process where generalizations are formed based on specific observations, and the bandwagon effect involves adopting a belief or behavior simply because others are doing it, rather than based on evidence or reason.
