"So what if it’s placebo? If it works then I'm fine with it."

# Initial exploration:

I recall somebody saying something to the effect of: "So what if it’s placebo? If it works then I'm fine with it."

The context was a discussion where somebody believed in god because he felt good because he believed in god. And he knew about the placebo effect. And I guess he wanted to defend against the question, "how do you know it's not placebo effect?" So instead of deciding that it's not placebo, he decided that even if it's placebo, that's fine. This means knowingly fooling yourself.
