korien_jan29It’s hard to quantify a person’s personality scientifically, but one factor that is relatively easy to measure is introversion vs extroversion. We think of an extrovert as someone who enjoys being with other people and an introvert as someone who is shy and likes to be alone, often spending most of their time reading or studying. However, there are extroverts who enjoy reading and introverts who enjoy partying with friends or performing on stage. The difference is that extroverts receive energy from being around others, while introverts find it uses up energy and they need alone time to recharge.

人の性格を科学的に測ることは難しいですが、わりと簡単に測れるのが外向性と内向性です。外向的な人は他の人に囲まれていると幸せで、内向的な人はシャイで一人が好きなので勉強や読書に時間を費やすというイメージがありますが、読書が好きな外向的な人もいれは、パーティー好きで、舞台に出る内向的な人もいます。違いは、外向的な人は他人からエネルギーをもらいますが、内向的な人は人といることでエネルギーを費やし、一人の時間でエネルギーを充電する必要があります。
