What is fallacy of false generalization?

The fallacy of false generalization occurs when a conclusion is drawn about a whole group based on insufficient or unrepresentative evidence. This often involves making sweeping claims from a limited sample size or misinterpreting specific instances as universally applicable. For example, if one encounters a few rude individuals from a particular city and concludes that all people from that city are rude, it exemplifies this fallacy. Such generalizations can lead to stereotypes and misleading assumptions about groups.
