This is a perfectly acceptable question in a science course. Just because you don't have the experience, knowledge, or, barring those two, even just the imagination to understand how a question might apply doesn't make it strange or dumb. It does speak volumes about you, though.
Exactly. Citing a psychology paper from 1912 is risky business. Young people don't know precisely when each particular science caught up to the current paradigm.
Is it though? I definitely had teachers in middle/high school with oddball requirements like "only physical books more than 10 years old are valid sources". Total nonsense but it does happen. College is a place where you are meant to have these bad assumptions challenged and corrected. Presumably after a response they'll be better for it.
