Facile
Definition: easy, shallow, or simplistic
It’s often used to mean “overly simplistic.” Someone who has a “facile solution” is not thinking about the problem hard enough.
Why I Looked It Up
I’ve been seeing this word forever. I think that I thought it mean flexible?
I can’t remember exactly where I found it, but I kept the quote, so it much have been an apologetic of some kind:
Faith is too easy, too facile.
