(4:18) Those are the extroverts.

(4:20) Let me deal in a bit more detail with extroversion, because it's  consequential and it's intriguing, and it helps us understand what I call our three natures. First, our biogenic nature -- our neurophysiology. Second, our  sociogenic or second nature, which has to do with the cultural and social aspects of our lives. And third, what makes you individually you -- idiosyncratic -- what I call your "idiogenic" nature. 

(4:52) Let me explain. One of the things that characterizes extroverts is they need stimulation. And that stimulation can be achieved by finding things that are exciting: loud noises, parties and social events here at TED -- you see the  extroverts forming a magnetic core. They all gather together. And I've seen you. The introverts are more likely to spend time in the quiet spaces up on the second floor, where they are able to reduce stimulation -- and may be misconstrued as being antisocial, but you're not necessarily antisocial. It may be that you simply realize that you do better when you have a chance to lower that level of stimulation.

(5:41) Sometimes it's an internal stimulant, from your body. Caffeine, for example, works much better with extroverts than it does introverts. When extroverts  come into the office at nine o'clock in the morning and say, "I really need a cup of coffee," they're not kidding -- they really do. Introverts do not do as well, particularly if the tasks they're engaged in -- and they've had some coffee -- if those tasks are speeded, and if they're quantitative, introverts may give the appearance of not being particularly quantitative. But it's a misconstrual.

(6:18) So here are the consequences that are really quite intriguing: we're not always what seem to be, and that takes me to my next point. I should say, before getting to this, something about sexual intercourse, although I may not have time. And so, if you would like me to -- yes, you would? OK.

(6:40) There are studies done on the frequency with which individuals engage in the conjugal act, as broken down by male, female; introvert, extrovert. So I ask you: How many times per minute -- oh, I'm sorry, that was a rat study –

(7:01) How many times per month do introverted men engage in the act? 3.0. Extroverted men? More or less? Yes, more. 5.5 -- almost twice as much. Introverted women: 3.1. Extroverted women? Frankly, speaking as an  introverted male, which I will explain later -- they are heroic. 7.5. They not only handle all the male extroverts, they pick up a few introverts as well.
