Why do extroverts like action, and introverts like calm?
It has to do with two powerful chemicals — dopamine and acetylcholine, “jolt juices” that hugely impact our behavior, according to J. Allan Hobson, a professor of psychiatry at Harvard.
Dopamine gives immediate, intense zaps of happiness when its users act quickly, take risks, and seek novelty.
You’re not imagining it. That extrovert who seems so different from you? It’s because his brain is different.
