For number 4 I was stumped. I hate it when questions on quizzes lump things together like that, because often I agree with half of one and half of the other. I would've loved to have put "difficult but interesting". I find small talk hard to do and understand but still interesting. I just marked one and adjusted my score at the end by splitting "4" in half.
So I came out 60% extrovert, 40% introvert but I'm adjusting to 55% extrovert, 45% introvert.
But I immediately noticed some of the questions don't have a real logical connection to extroversion/introversion.
For example, curl up with a good book versus watch a movie? It depends on how you are watching the movie. Some people like to sit alone by themselves and watch movies all day. I wouldn't call that extroverted. Similarly, some people like to read stories to each other. Not exactly introverted. I put movies, which I love even if I'm alone but I'll admit are more fun if there are other people around watching it.
7 makes no sense either. Think out loud versus think before you act? They're not even mutually exclusive and I tend to do both at once. I put "think out loud" because I do this a lot just to concentrate over the noise, but I am sometimes very impulsive so I don't always think before I act.
The first question confused me to. "Talking" is better for my personal happiness but I look like I'm "listening" more because I can't think of what to say. But then I'm often not really listening and my attention drifts during the conversation.
