This expression is a derogatory descriptor used to cast doubt on the value of the speaker's information and views. Generalizations, as a class of statement, are usually subject to this form of criticism unless qualified by the speaker's idiom. Sweeping generalizations are also implied to be oversimplified and ignoring other facts. In conversation, the use of the expression is usually a flashpoint for debate on the quality of knowledge of the subject.
Examples of Sweeping Generalization:
|Sweeping generalizations are always wrong.|
Not wanting to make a sweeping generalization myself, but are they always wrong?
Not a sweeping generalization, more a mild brushing.
