Preparation, with the support behind it

“Set and setting” — mindset going in, and the physical and social environment around the experience — is one of the older ideas in this field, and it holds up reasonably well against more recent research. Studies looking at what predicts how a psychedelic experience goes have found that factors present before anything starts, like expectation and readiness, correlate with people’s later reports of how manageable a psychedelic experience felt. That is consistent with a placebo-adjacent mechanism: context and expectation shape experience, which is a real effect, not a dismissal of the experience itself.

Separately, a psychological flexibility framework — being willing to have a difficult feeling rather than needing to control or avoid it — has been proposed as one lens for supporting people through psychedelic-assisted work. It is one model among several, not a settled consensus, but it maps onto something practical: acceptance-based coping tends to serve people better in the moment than the alternative of fighting what is happening.

None of this is about mindset controlling outcome. Research on implementation intentions — plans made ahead of time in a specific if-this-then-that structure — has found they help people carry through on decisions made in a calmer state precisely because deliberation is harder in the moment itself. That is a mechanism for why preparation done in advance, not improvised in the moment, is the more reliable kind. See Deciding things early and the Sheet for what that looks like in practice.
