Extroversion

Extroversion here is a description of where a person gets energy and how well they receive it, which is closer to the folk understanding than to the psychometric one. An extrovert is someone very receptive to anima from other people, so an anima transfer in public gives them euphoria, and the enjoyment named in the definition is the experience of that transfer rather than a preference for company. The counterpart entry makes the framing clear. Introversion is fear of social interaction because of experienced deanimation, which places both terms on one axis running between good and bad prior experience of the same kind of transfer rather than between two temperaments. That is a strong claim and it is worth stating plainly, since it implies introversion is a learned response to depletion rather than a stable disposition. The mechanism belongs to the account of channelers and audiences. Anima transfer supplies the energy a star in a theatre can take from an audience and return magnified many times, leaving the whole audience euphoric, and it is the same energy that gives the performer their glow and attractive force in the first place. Receptivity is what determines who benefits from being in that room. The same anima may be obtained from contact with a channeler, accessed at live theatre, abstracted by watching a film or taken by stalking the channeler's private life, and only the first two are balanced.

Extraversion is one of the five factors in the dominant model of personality, measured by scales going back to Eysenck, treated as substantially heritable and stable across the lifespan and associated in the research with reward sensitivity and dopaminergic function. The popular understanding, that extroverts gain energy from company and introverts lose it, is not the psychometric definition and is often corrected by researchers. Marsh's account effectively endorses the popular version and supplies a mechanism for it. Where the trait literature treats introversion and extraversion as poles of an inherited disposition, she treats them as outcomes of what previous interactions delivered, which makes the position revisable in a way the personality model does not predict.
