What term describes a fallacy that uses an example that is not representative of a broader category?

The term that refers to a fallacy using an example that is not representative of a broader category is "Selected Instances." This fallacy occurs when someone presents specific instances or examples as though they are representative of an entire group or category, despite lacking sufficient evidence to support such a claim. By focusing on isolated cases, the argument can mislead the audience and distort the overall picture, leading to conclusions that may not be accurate.

For example, if a speaker highlights a few extreme cases of poor performance in a particular profession and argues that all individuals in that profession are incompetent, they are relying on selected instances without considering the broader context. This tactic can create a skewed perception that does not reflect the true nature of the group in question.
