Where the phrase comes from

For about four hundred years, devil's advocate was an actual job. When the Catholic Church considered declaring someone a saint, one official had to argue against it. His title was Promoter of the Faith, promotor fidei in Latin, and he put every objection to the candidate's life and miracles in writing, weak ones included. Everyone else argued for. He argued against, so people called him the devil's advocate.

The office became a formal part of the process in 1587, under Pope Sixtus V (Britannica has the short history). In 1983, Pope John Paul II rewrote the rules for naming saints. The Promoter of the Faith now chairs a panel of theologians and sits in on the final meeting without a vote (the 1983 rules). The title survived. Most of its power didn't.

Everywhere else, the phrase now means arguing for a side you don't necessarily hold, to see whether the other side survives the pushback. It's also a way to say something unpopular and keep your hands clean. "Just playing devil's advocate here" has started a lot of arguments nobody needed.

How to argue a side you don't believe

  1. Steelman it

    A straw man is the weakest version of a side, built to fall over. A steelman is the strongest version, the one its smartest fan would make. Start there. Someone who says decaf is a lie isn't confused about beans. Their point is that coffee exists to deliver caffeine, and decaf is the box with no gift in it. That's a position you can stand on.

  2. Find the one reason you can live with

    You don't need to believe the whole side, just one reason in it you'd nod at if someone else said it. Maybe reclining your airplane seat all the way is rude. But you paid for the seat, and the airline put the button there. Build on that and ignore the rest. One reason you half believe beats five you don't.

  3. Borrow a real story

    Real opinions come with stories, and a side without one sounds rented. It doesn't have to be your story. Borrow your sister's or your coworker's. "My roommate left a pan to soak for nine days" does more work than any general point about dishes, because now everyone is picturing the pan.

  4. Concede small to win big

    Give the other side a point it's right about. "Fine, a picnic is technically eating on the floor." People trust someone who admits a weak spot, and they stop waiting for you to crack. Then move to ground you can hold: sandwiches taste better outside, and there are no dishes.

  5. Don't oversell it

    The quickest way to sound fake is to care more than anyone else at the table. If the question is silly, treat it as silly. Give your reason, shrug, and let someone else get worked up. Keeping a straight face is its own skill, and we have bluffing tips for that.

When it helps, and when it's just annoying

Arguing the other side on purpose is useful when a group agrees too fast, because a plan nobody has pushed on hasn't been tested. It's useful for you, too. Arguing against your own opinion is the quickest way to find out whether you believe it or just like how it sounds.

It stops being useful when the topic is a person. Playing devil's advocate about whether your friend deserved to get dumped is a pile-on with a fancy name. So:

  • Say you're doing it. "I'll take the other side" tells everyone it's a game, and then you're free to be outrageous.
  • Keep the stakes low. Food and manners are perfect. Anything about who someone is isn't.
  • Stop when someone at the table is actually upset. The debate is over, and you lost.

The one place you skip the first rule is a game where nobody is supposed to know you're faking.

Devil's advocate debate topics

Good practice topics are low stakes and a little absurd, with one side that sounds obviously worse. Defending that side is the drill. All of these are from Fuzzy Logic, the free deck in The Lobbyist.

Make it a game

Playing devil's advocate out loud is easy. Doing it while nobody knows is a game called The Lobbyist. Everyone answers a question on their own phone, in secret, and one player, the Lobbyist, is told to argue the side they didn't pick. Everyone argues, votes on who didn't mean it, and the phones show who was lying.

Every step above is how you play the Lobbyist well. At real tables, the Lobbyist got away with it 54% of the time, and here's what else we found. Or read how to play and try it on your own friends.

Questions people ask

What does playing devil's advocate mean?
Arguing for a side you don't necessarily believe, to test an idea or see whether the other side holds up. The name comes from an old Catholic Church office whose job was to argue against making someone a saint.
Is playing devil's advocate rude?
It can be. On a silly question it's a game. On something that matters to someone in the room, it's an excuse. Say up front that you're doing it, and drop it if anyone is actually upset.
What are good devil's advocate topics?
Low-stakes questions where a reasonable person could hold either side, like food fights and small points of manners. Skip anything that's really about someone at the table.
