Perception Problems

We think we experience the real world but we do not at all. Our perception of the world is deeply flawed

Look at colour constancy, where our brain decides what colour we should see. Or apophenia where we see patterns that aren't there. Or Chronostasis.

Our memories are flawed. Look at the Mandela effect.

We always focus on the negative. We are more sensitive to losses than gains. We overestimate the risks of that which is vivid and immediate.

We forget where we found information.

Still though, we might not know what we don't know.

The flip side of this is people are getting smarter all the time.
