How the brain fills gaps

The colors in this video aren’t real. Neither is most of what you see.

Your eyes don’t send your brain a picture. They send a little bit of data and your brain fills in the rest from everything you’ve already seen. Past experiences, your culture, whatever’s on your feed.

So what you see is really just your brain’s best guess at the world (they actually call it controlled hallucination).

Your expectations basically become your reality.

Kind of unsettling but powerful to understand.
