What does it mean to play devil's advocate?
It means putting the opposing case on purpose, whether or not you believe it, so that an idea gets properly stress-tested. Saying so out loud matters: it signals you are probing the argument, not stating your own view.
What is the difference between a devil's advocate and a contrarian?
A devil's advocate argues against a position temporarily and deliberately, to test it, and would usually say so out loud. A contrarian genuinely and habitually takes the opposing view whatever the subject. One is a technique; the other is a disposition.
Is playing devil's advocate a bad thing?
Not in itself — it is a recognised way of exposing weak reasoning before a decision is made. It gets a poor reputation when someone uses the phrase to float a view they actually hold, or to keep debating a sensitive topic at someone else's expense.
Where does the apostrophe go?
After the l and before the s: devil's advocate. The advocate belongs to one devil, so it is a singular possessive.
Where does the phrase come from?
From the Latin advocatus diaboli, the role in Catholic canonisation proceedings whose job was to argue against declaring a person a saint by presenting every objection and doubt. The opposing role was known as God's advocate.
