A sweeping generalization is when someone applies an assumption where it does not apply. Don't get this confused with hasty generalization. Many generalizations are not universal; they have exceptions. To ignore this fact is to commit a logical fallacy.

For example: "Jogging is good for the heart. Joe has a heart problem, therefore he should go jogging more often." It is true that jogging is good for the heart, but not for everyone. Most people with a heart condition would only worsen their condition by jogging. Therefore there is an exception to jogging being good for your heart, it is bad when you have a heart condition, so this does not apply to Joe.


"Nothing is true just because someone says it is. Therefore, we shouldn't trust everything God has said." This is obviously fallacious. Although it is true that people do not generally speak the truth, God is an exception; He never lies and He knows everything, therefore, we should take Him at His Word.

Sorry I could not provide a picture, I'm working on it.
