The top of the list

INTP, INFP, and INTJ live furthest inside their own minds. They don't just prefer solitude, they need it to think at all, and too much social contact leaves them genuinely depleted. INFJ is close behind: the most outwardly warm of the deep introverts.

The bottom of the list

ESFP and ESTP are the polar opposite: they think out loud, recharge around people, and find too much alone time flat and draining. Their energy is generated by the outer world, not the inner one.
