There's one last slice of pizza. Iz and Matteo both want it.
Dad proposes a rule: one of you cuts, the other picks first.
Discuss for 90 seconds: why does this rule work better than Dad splitting it himself?
The cutter can't cheat — so they cut fair
Picture it: you cut the slice. You make yours obviously bigger. You smirk.
Congratulations — you just handed Matteo the big piece. Because YOU pick last. That's the genius of cut-and-choose: cheating punishes the cheater.
It's why brothers splitting inheritance, pirates splitting treasure, and countries splitting fishing seas all landed on the same rule. Not because they were nice. Because nobody trusts anybody — and that's exactly why it works.
