I agree. Placebos can help too.

Fact is, for it to work as a placebo, you need to believe it will work.

I've had a few coworkers who had stuff like crystals on their desk because their partner believed in it. I understand why that stuff happens, the believer who (supposedly) cares about your well-being, gets benefit from it, and wants you to have the same or similar benefits from the same. But since they're doing it to placate their partner and don't personally believe, it's just a rock on their desk.
