The handshake is one of the most universal human gestures. You do it without thinking — at job interviews, business meetings, introductions, deals. But have you ever stopped to ask: why this particular gesture?
The Standard Story
Most people, if they think about it at all, assume it evolved as a way to show you were unarmed. Open hand, no weapon. A gesture of peace.
That explanation is neat. Perhaps too neat.
The Uncomfortable Questions
If it was about showing you had no weapon, why the right hand specifically? Left-handed warriors existed. Why the grip and the shake rather than just an open palm?
Some historians point to an older purpose: the shake itself was meant to dislodge any knife or dagger hidden up a sleeve. It wasn’t trust — it was verification.
Others suggest the handshake was a ritualised form of oath-taking. In ancient Greece, the dexiosis — a clasping of right hands — appears on funerary art and treaties. It was a binding gesture, not a casual one.
What Nobody Asks
Here’s the question worth sitting with: why do we still do it?
The practical reasons — weapons, oaths — are long obsolete. Yet the handshake persists across cultures that never shared these origins. It has been adopted, exported, and formalised into business protocol worldwide.
Who benefits from a ritualised gesture of equality between two parties? What does it signal when someone refuses to shake your hand — and why does that refusal feel so charged?
The handshake might tell us less about history and more about how humans manufacture trust through choreography. We perform trust before we feel it. The gesture creates the relationship it claims to merely represent.
Something to think about next time you extend your hand without thinking about why.
