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.
For example, extraversion is said to include such related qualities as gregariousness, assertiveness, excitement seeking, warmth, activity, and positive emotions. -- https://en.wikipedia.org/wiki/Big_Five_personality_traits
This is a new experimental weekly thread.
Guidelines: Top-level comments here should be links to things written by members of the rationalist community, preferably that would be interesting specifically to this community. Self-promotion is totally fine. Including a very brief summary or excerpt is great, but not required. Generally stick to one link per top-level comment. Recent links are preferred.
Rule: Do not link to anyone who does not want to be linked to. In particular, Scott Alexander has asked people not to link to specific posts on his tumblr. As far as I know he's never rescinded that. Do not link to posts on his tumblr.
