You’ve landed in a new city with no internet connection and you’re craving an authentic Thai meal. You’ve heard there are great restaurants down by the wharf, so you wander there with your friends.
Turning the corner, the smell hits you first — spicy, fragrant, unmistakably Thai. Then you see them: two tiny hole-in-the-wall restaurants facing each other on a narrow street.
One is buzzing. Nearly every table is full. The other is quiet, with only a couple of diners inside.
Which one do you choose?
Most people pick the busy one. Not because they’ve tasted the food, but because their brain whispers, “If everyone else is here, it must be good.”
Robert Cialdini calls this social proof, our tendency to look to other people to decide what to do, especially when we’re unsure. If lots of people are doing something, we assume it’s the right choice.
How this helps with everyday persuasion
In hospitality and retail: Reviews matter. I recently bought a product online that I was genuinely sceptical about, but the sheer number of positive reviews tipped me over the line. It worked, but the only evidence I had was what other people said.
In workplace culture: If everyone is wearing the correct PPE – hi-vis, ear protection, goggles – that behaviour becomes the norm. Compliance feels natural because it’s visible, consistent, and socially reinforced.
But the opposite is also true.
If your organisation says it values safety, yet people routinely ignore those standards, then what employees see will outweigh what’s written in policy. Social proof cuts both ways.
The persuasive takeaway
Next time you want to influence behaviour, ask yourself:
“Can I show evidence of people already doing this?”
Because when people see the behaviour, they’re far more likely to follow it.
