Which reasoning error suggests a conclusion based on a single experience?

The reasoning error that suggests a conclusion based on a single experience is known as Hasty Generalization. This fallacy occurs when someone makes a broad generalization based on insufficient evidence, such as relying on one anecdotal incident to draw conclusions about a larger group or trend. For instance, if a person tries a new restaurant once and dislikes it, then claims that all restaurants of that type must be bad, they are committing a Hasty Generalization.

This type of reasoning is problematic because it overlooks the need for a more comprehensive examination of the evidence before forming a conclusion, which could lead to inaccurate stereotypes or misconceptions. Overall, Hasty Generalization highlights the importance of gathering adequate evidence and considering a wider range of experiences before making definitive claims.
