Sometimes it seems like this world is built for extroverts. The most successful politicians, entertainers, and public figures are (or at least come off as) extroverts. One of the “Big 5” personality traits we use to judge and praise people is extraversion (Introversion, falsely assumed as simply the lack of extraversion, doesn’t merit mention.) Certain studies suggest that extroverts make more money than introverts, on average. Extroverts tend to be happier than introverts, regardless of the cultural context. Introverts are more likely to suffer from depression and asthma. (This Mark's Daily Apple article was written by Mark Sisson, and is narrated by Tina Leaman)
