Unreasonable, and inappropriate while not particularly useful:
Why are so many college students not critical consumers of information? How can instructors help students learn to vet what they read and incorporate into their own writing? Google, Wikipedia, and suspicious journals are not the root of the problem.
Primarily, this is a call to instructors and librarians to spend less time developing guard rails around (in)appropriate sources, and more time asking students to think through the material they cite.
