A PhD wouldn't know anything about science, so its pretty accurate really :/
Edit: It's the internet so naturally im being downvoted for learning but after looking it up, I was wrong. The PhD does stand for philosophy doctorate, but no longer refers specifically to the feild of philosophy as it once did. Apologies to anyone offended.
The trick lies in philosophy coming from Greek philosophia which is love for/love of wisdom. It never referred to what we understand as philosophy, but rather affinity for studying.
