"shamanic practice. The latter, she maintains, is based on a complex, multi-tiered metaphysics whereby cause and effect relations beyond the visible material world are deliberately exploited by the shaman."

Yeah ok

I didn't bother reading this in details, but from what I've seen it seems like a same argument as "an homeopath makes people feel better because they talk to people nicely and makes them feel heard so it's not just placebo".

There's not really any point in trying to support religious magic healing at this point. People already believe in a gigantic amount of scam and have no critical thinking, and you start debating about the exact definition of what is a placebo effect even though it's one of the only few bits of "critical thinking" knowledge that people have?

Nah, that's absurd bullshit.
