A new app uses the power of your own positive thinking to create a placebo effect—which works even if you know it’s happening.
You start by setting a goal: say, more joy or love in your life. Then, you choose someone to give you the placebo (maybe a friend or family member), what you want it to be (a pill, say), and where you want to take it (maybe a forest where you go running with a friend). You then “take” the placebo whenever you want to, following a pre-set ritual built into the app.
The point is to replicate what’s important about the placebo effect, which isn’t the pill itself, but the experience.
