Introverts tend to internalize problems. In other words, we place the source of problems within and blame ourselves. Though introverts may also externalize and see others as the problem, it's more convenient to keep the problem "in house." Internalizers tend to be reliable and responsible, but we can also be very hard on ourselves.

Collectivistic societies, such as those in East Asia, value privacy and restraint, qualities more characteristic of introverts.
