The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.

So the short story is that all of the changes that we saw both psychologically and neurobiologically were seen with the 25 milligrams. It all happened with that big whopping dose. And what did we see? Well, we did see significant improvements in psychological well-being. We saw what I call the entropic brain effect, which is actually formerly quite accurate. We see an increase in the informational complexity of ongoing brain activity recorded with the EEG on the dose of psilocybin.
Psilocybin increased brain plasticity, desynchronized default networks, resulting in enhanced creativity, playfulness, and openness, with reduced mental rigidity.
Neuroplasticity Psilocybin increases brain entropy, breaks rigid patterns, and boosts long term cognition and flexibility.
A study with 28 healthy participants who had no prior psychedelic experience showed that a single high dose of psilocybin increased brain entropy after 1 and 2 hours. This entropic effect predicted long-term structural and functional brain changes, improved well-being, and enhanced cognitive flexibility at 1 month.
A recent preprint also demonstrated increased cortical entropy during the psilocybin trip 1-2 hours following a single 25 mg dose, in participants with no previous psychedelic experience (psychedelic-naive). This entropic effect also predicted long-term structural and functional brain changes measured by MRI at 1 month, improved well-being, and cognitive flexibility.
