Do shrooms really improve quality of life?

For context, I’ve never taken shrooms but almost every person I meet who’s taken them for therapeutic purposes say they helped somehow. But how can we be sure it’s true?

I’m not doubting their capability, but someone who’s taken them wouldn’t know any better if the “improvement” was just an illusion. For example, when you’re drunk you feel like the king of the world, but everyone else sees you acting like an asshat.

And how often do we see successful people who’ve taken shrooms? Or any psychedelics? I know Steve Jobs did for sure but I haven’t heard about any others.

Once again I’m not skeptical, just curious. I’m posting this because I’m considering trying them myself.
