Why is perception so hard?

I recently read very interesting book, about neurosciences and thinking differently.

Basically, relates brain being energy efficient, meaning taking shortest path where possible. This means that if you look something, brains try to explain that based on your experiences what you see - the most natural reasoning. So you dont see what eyes see, but what brains explain them.
However, here comes interesting point, which is that every persons experiences are different, thus also the interpretation.

This can get interesting when seeing something new - brains try to explain it in a way they know.
The Fast Company has an excellent article describing this:

Explain the Internet for a 19th century street urchin

In order to break this there needs to be something knowingly unconventional to make brains break experiencr explaining and trying to learn what is whar you are looking for. This explains why also brainstorming at office does not work, and why you get ideas middle of night, or some place else than work.

This also means that having work requiring high tempo requires both skill and experience - on that specific area. And that misunderstandings on meetings are due that we are different, terms, background - sometimes even goals.

Thought originally writing longer article but this is sufficient now.
