How much do you really know? The Knowledge Illusion by Philip Fernbach and Steven Sloman argues that you know less that you think you do.

We’re all ignorant.

Here's three takeaways that are worth thinking about, in a short thread:

1-We don’t know the details of how things work, because we don’t need to. We can rely on experts to know how our bike or toilet works (you think you do, but you don't).

But this is a problem when our opinions influence others or matter for other reasons (like elections).

2-Much of our thinking is done by our bodies.

This idea is called embodied intelligence and affects everything from catching a ball to our deepest fears.

We are not rational.

3-Humans are built to collaborate.

Dividing cognitive labor in well-functioning teams is the key factor in enabling progress.

Team function does not correlate with combined-intelligence of the group members.

If you enjoyed the thread, your followers probably will too. Retweet the lesson that resonated.
