A lot of the discussion about introversion and extraversion seems to collapse a whole bunch of things into a single binary. When people point out that they’re not well-described by either term, they tend to come up with patches like “ambivert,” but this is a missed opportunity to develop a more granular understanding of sociability. There are enough tensions in the underlying definitions that I want to blow up those terms and replace them with more precisely defined axes along which people vary:

I’m not clear about the difference to the sub-components of extroversion that is e.g. automatically identified by the PCA analysis behind Big Five.
