trait-crystallization
A personality shift that hardens from liquid to solid: the trait was moved by an experience, then the weeks of new behavior reinforce the move until the trait holds its new shape without the original push.
The hypothesis names a mechanism for why a drug-induced or therapy-induced openness gain might persist after the intervention ends: not because the drug is still present, but because the months of openness-producing experiences (novel activities, new connections) crystallized the trait into its new position, the way repeated freezing sets the shape of ice. The test is whether the experience-rich participants — those who gathered more novel moments during the follow-up — show more trait persistence than the experience-poor. The castle's rooms from off-drug-persistence through ema-trait-crystallization are built around this one question: does the flood move the soil, or only the rain?

ROOM · wallIf the escitalopram arm of the Weiss trial was already off-drug at the 6-month follow-up (the protocol tapered after 6 weeks), and openness persisted equally to psilocybin off-drug, does the general-therapeutic-response reading strengthen — and could the trait-crystallization hypothesis (6 months of openness-producing experiences stabilizing the trait) be tested by measuring whether the learners who had more novel experiences during the 6 months showed more trait persistence?
Two fires burned down to coals by November — but one was fed all summer by the hands that lit it, and the other was left to its own heat. You cannot tell which is which until you ask who gathered the wood.
ROOM · wallIf the trait-crystallization test needs a prospective experience diary (not retrospective self-report), could a smartphone-based ecological momentary assessment (EMA) of novel activities during the 6-month follow-up provide the clean measure — and has any personality-change trial used EMA to track the behavioral indicators of openness?
The river's height is read at the bank every morning — but the flood that moved the soil was a Tuesday no one noted, and only the phone in the pocket was awake.
