As children, I think we were all curious about our reality. In fact I'd say most of us actively tried to learn more about the mysteries of reality via the only we could at the time: asking questions. Asking questions about anything that didn't quite make sense. Children are known to ask question after question until they eventually questioned the framework of our knowledge, with questions like "Why does anything exist?" or "Why is this bad and why is this good?" In a way, most children are like mini philosophers. Unfortunately, a child's quest for knowledge is severely limited. Parents cannot answer or explain many of the questions kids have. And even if they could, a child's limited ability for complex and abstract thought hinders their ability to understand the answers to many of their questions.

You would think that as we grow older our curiosity and enthuasiasm for knowledge would increase. Our sources of information have vastly opened up and our more capable brains have equipped us to actually understand most of the information. It only makes sense that we would at least try to explore some of those questions we had as kids, rather than being satisfied with the "it just is" mentality. Unfortunately the complete opposite happens with most people. Even with increased access to knowledge and superior cognitive capacity, it seems age correlates negatively with curiosity. As we grow older we become more aware of some of the mysteries of reality, yet for some reason we become less inclined to seek answers. Ironic, isn't it?

Why do you think this happens? Some might say asking too many questions threatens the framework of our understanding of reality, which frightens some people. This could be true, and if so, I think it's very unfortunate that people are embracing ignorance for the sake of ignorance. Some people take it a step further than simply being apathetic towards learning more about reality; some people even discourage such thinking, claiming that it's acceptable to not want to explore the bigger, more mysterious questions of the universe. Essentially, such thinking is accepting ignorance.

So why do you think this happens? Obviously you can't read the minds of other people, but what about yourself? If you stopped being curious about the world as you aged, why? Did authority discourage you from asking questions enough until you eventually gave up? Also, when did this happen? When you were just a small child or an older teenager, or were you never curious about your reality? Were you scared that if you asked too many questions, it would threaten the very basis of your knowledge? Or did you never lose your sense of curiosity and you continue to ask questions today? I ask because I'm curious.

Some people seem to be content with what they know and they want to keep it that way. Still, no one just plain stops asking questions. Everyone asks questions throughout the years of their lives. It doesn't stop, we always will ask why or why not, etc.

Everyone asks because they are curious. Everyone is curious of something out there.

I think part of it is the fact that, as a child, you don't really know very much, and you look around and see all of these grown-ups around you and assume that they know everything. As you mature, you learn more, and you realise that the people around you aren't omniscient. Even the smartest people you know can be wrong, or have no idea what the answer to a question is. As a child, you kind of accept the half-answers that you can be given, but as an adult they frustrate you. The hardest questions (What is the meaning of life? Why are we here? What is love? What caused the creation of the universe? Do we have free will?) don't have answers, so some people just lose all enthusiasm for asking them.

Also what Basil said: why ask a feeble human when you can just type the question into Overlord Google?

Well I didn't mean just verbally asking questions. I meant generally looking for answers which it seems like most people don't do anymore. Maybe I should change the title.

I don`t think people stop making questions. The thing is people grow up and most of people`s lifes stops being about new things.
In essence it`s a bit like love: at first it`s a wonderful thing; something new. After, whilst being important, people are more focused and try to apreciate it.

People always make questions and search for an answer to this or that even if they are more silent or laidback about it.

I am studying physics.... So I have now decided to leave understanding to people more intelligent to myself, the full details are just far too confusing

It's simply biological. The brain is designed to be curious as young and stationary when mature.

I asked questions until I got to relativity and quantum mechanics, then shit got cray :D

While I agree with the general thesis of the OP, I maintain that I do not fall into that category myself. My life has been one long search for answers.

i stopped looking for answers after the PS4 was revealed
