I teach at the college level. In the first day of class I inform my students that they cannot use Wikipedia as a reference source for term papers or essays that they are assigned.
I have this policy precisely because Wikipedia is so faulty and so full of false information. Sometimes I use this policy, by the way, as a “teachable moment,” to teach what it means to use reliable sources of information.
I agree that Wikipedia shouldn’t be used as a reference, but it is a very useful starting point, most of the time.
