This is not to (as my post above suggests) prevent irrational thought during the trip itself, but rather to ensure that one is properly prepared, once sober, to reflect critically about their experiences, and avoid common epistemic mistakes people make post-psychedelics
This seems like the right place to intervene. Psychedelic trips are somewhat similar to mystical experiences, and there the problem tends to be taking what was experienced and trying to turn it into something like a universal truth. So, it quickly jumps from “I felt warm and connected” to “I was in the presence of God” or whatever else is ready at hand in the person’s mind. Stated otherwise, you mostly have to watch out for overfitting the data to a pattern you want to be true.
