I don't think that there evidence that it's very useful. Knowing the label "appeal to authority" doesn't tell you anything about when you want to believe in an authority when when you don't.
The whole idea of teaching logical fallacies without providing the student any evidence that it's useful to teach logical fallacies also very ironic. In the real world scholarship is important for understanding a topic on a higher level.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
