I feel highly certain that outcomes are ~all derived from the effect of psychedelics on the default mode network of the brain, and the corresponding downstream effects of those changes on thinking, perception, emotions, etc.
Google: "microdose" "default mode network" and you will get tons of reading material - I would recommend reading a mixture of clinical studies and anecdotal narratives. Take everything with a grain of salt of course, but also keep an open mind. This is new territory, we know very little about it.
> For instance, is the effect only temporary, in the sense that it unlocks some region of not normally traversed mental state space? (E.g. allowing you to write paragraphs you wouldn't otherwise be able to.) Or is the effect more permanent, in the sense of teaching you something, providing you with a new muscle which can be used later even in a sober state of mind (teaching you to ride a type of brain bike, which then can't be unlearned), or by showing you connections between disparate ideas you hadn't previously had the ability to see next to each other?
I would say, speculatively: all of the above, potentially, depending on the person. The "correct" answer to such questions is currently not known, but this seems very difficult for many to realize, which is quite ironic.
