A man sat down and thought that his life was worthless and something needed to be changed. Naturally, he does not want to change anything, and indeed he has all the "norms", but he wants to satisfy the momentary need to satisfy the endorphins on the road. Here he will watch a 5-minute vidos with facts about which he is already aware, will smile, will not make any mental effort and will go on surfing the Internet.
You will be surprised, but everyone uses the head in different ways. Neither the ability to reason sensibly, nor the "moral law" is given to a person from birth, it is the result of socialization. And this not works in such a way that, for example, the child naturally develops empathy on his own, observing others and drawing parallels between himself and them, and draws from this how he should behave with people. In most cases, parents need to sit down and explain and inspire in plain text, or from early childhood, specifically develop the ability to think independently. But parents are all different - someone considers too much obvious, someone is not very good at pedagogy, someone just has no time. Influence of school, peers, etc. also all different. So it is natural that many only at a relatively mature age "think" about things that seem elementary to others.
I guess other people use their heads for the same things you do. It's just that people usually don't think about things that have nothing to do with them. However, when such things come into our field of vision, we think about them. Nabokov sarcastically over the expression "makes one think", adding in parentheses after him "whatever that means", nevertheless, there were things that Nabokov himself never thought about - and if he encountered something new for his thinking, he, too, most likely had to think about something for the first time. The whole point, of course, is in the word "compels" - but just this phrase itself has become a common expression, which is much easier to use than to independently choose words that are more accurate and successful.
We live in a world of information noise, and on the basis of such cases also procrastination. Most people don't sit down and think a little; weigh the pros and cons". It is easier to pay money for an undesirable training, to read a book on psychology in a lot of water than specifics, and in general, why bother yourself? Better to watch mamas.
If you really do not be so categorical, a person may not have yet reached through a thought, therefore feeds through a prism - gradually putting together the puzzle of "ideas / thoughts", etc.
