Did you hear about George Clooney? They say he tips hotel staff a hundred euros for a good espresso.
And Elon Musk sleeps only two hours a night to “maximize productivity.”
We don’t know if that’s true — but somehow, we all care. Because gossip isn’t about information — it’s about connection.
It’s how humans say: You and I, we’re in the same tribe.
It all started long before Instagram — with monkeys picking fleas. They called it grooming. We call it gossip.
While chimpanzees build bonds through physical grooming, humans evolved a shortcut — language. As a famous anthropologist Robin Dunbar said, gossip is “vocal grooming.”
A monkey grooms one friend at a time — but I can “groom” all of you right now, through speech!
Yuval Noah Harari calls gossip part of the Cognitive Revolution. About 70,000 years ago, humans learned to talk about things that don’t physically exist — to share stories.
Lions can roar about danger, but only humans can discuss:
- someone’s reputation,
- or plans for next month.
This ability to talk about the unseen let us cooperate in an unprecedented way and build large societies.
Even today, over coffee, what do you talk about? Who got promoted. Who’s dating whom.
It’s not shallow — it’s human. Through gossip, we:
- learn social norms,
- spot trustworthy people,
- and strengthen belonging.
Our ancient campfires became digital ones. Every time we check social media or chat at work, we’re doing what helped our ancestors survive.
But there’s a catch. Evolution designed gossip for small tribes — about 150 people — the social brain limit.
Now we gossip about thousands we’ve never met. Our stone-age brains weren’t built for that much social noise.
And when our brains get overloaded, gossip stops bonding — and starts judging.
What once built trust can now spread harm.
Understanding gossip’s purpose doesn’t excuse harm. Ask yourself:
- Am I sharing this to help others?
- Or to lift myself by pulling someone else down?
The same instinct that built civilization can also destroy trust.
So, next time you share a story about an absent friend — remember — you’re practicing one of humanity’s oldest arts. And with this ancient power comes modern responsibility.
Now look right , look left : and select a partner for gossiping. Think: with whom would you rather talk, and with whom better not?
And: gossip wisely, gossip kindly, and remember: this simple act helped make us the most cooperative species on Earth. If you enjoyed this speech… feel free to gossip about it when I leave the room. And if you did not like this speech, you still can gossip about all my mistakes. I will still appreciate being your social glue.
