A neat article that gives clarity on the introversion/extroversion spectrum (not binary), and explores how we should use knowledge of these personality traits, rather than using these labels as crutches or stereotype-enhancers.
(Applies to other personality labelling models like MBTI too!)
Thanks for this btcprox.
If you get a chance, read Malcom Gladwell's examination of the nonsense of Myers-Briggs. The article is called "Personality Plus" and was originally published in The New Yorker.
