I think sometimes bravado of knowledge can play into this. People as they become adults like to think they are very knowledgeable and don't want to come across as "stupid".

This means most adults will never ask the simple questions and pretend like they understand something complex quickly or already know. It's a dangerous mindset to develop but it's difficult not to.

As most on here are programmers how many times have you been in a meeting or technical discussion where you are judged for asking a "simple" question?

We need to stop the judgement of those that ask "simple" questions.
