Myths about introverts

I've been quite enjoying Austin Kleon's tumblr thing, which is full of short bites about creativity and other stuff. Recently he posted on Myths about Introverts, because he is apparently married to one. So, I thought I'd share this link, just to annoy the extraverts ;) (and I'll be the first to admit that some of these characteristics need to be overcome, in the name of Christian 'brotherliness').

I did think this was an interesting little piece of biology from the introductory spiel:

A section of Laney’s book maps out the human brain and explains how neuro-transmitters follow different dominant paths in the nervous systems of Introverts and Extroverts. If the science behind the book is correct, it turns out that Introverts are people who are over-sensitive to Dopamine, so too much external stimulation overdoses and exhausts them. Conversely, Extroverts can’t get enough Dopamine, and they require Adrenaline for their brains to create it. Extroverts also have a shorter pathway and less blood-flow to the brain. The messages of an Extrovert’s nervous system mostly bypass the Broca’s area in the frontal lobe, which is where a large portion of contemplation takes place.

Oh, and I also liked this bit :) :

In fact, one study (Silverman, 1986) showed that the percentage of Introverts increases with IQ.
