Evolution of Signalling and Early Brains

In the noble quest to understand our minds, today we take a new angle. We track how grunts turned into gossip, myths, and the weird human habit of blushing when we screw up.

You’ll see why your brain is basically a compression algorithm: squeezing an entire inner universe through a tiny mouth-shaped funnel. We go from jellyfish nerve nets to gossip networks, and beyond. How shared stories make money, nations and even your job “real”.

Along the way, we poke at shame, status, and why your reputation now travels faster than any spear ever did. It’s part history, psychology, mindset lesson, and part mirror.

You’ll probably recognise more of yourself than you’d like:

• Use “compression” as a mental model to communicate ideas more clearly.

• Spot how gossip and reputation are driving your current career decisions.

• Rewrite one story you’ve inherited about status, success, or failure.

Listen in, and update the story your brain is running in the background.
