I agree with most/all of this, it just seems like the question is, do they prefer those chill settings because of the increased intimacy OR the safety and relative lack of chaos. Increased positive experiences or decreased aversion? By aversion, I mean, are there sensory issues with crowds? feelings of overwhelm? more social anxiety at the uncertain? etc.

In other words, would introverts who had stronger social skills and newly managed social anxiety symptoms still make the same choices? I think the answer is a pretty solid "I/We don't know" but at least people are working on finding out!
