Social Proof

Read online


Incredible marketing can be incredibly simple.

In 2007, two Chinese researchers ran an experiment at 13 Beijing restaurants¹.

Some diners were sat on tables with a plaque listing the most popular dishes.

Others were sat at tables with no plaque.

Did the plaque change what people choose?

Diners who saw the most popular dish plaques were 18% more likely to order one of those dishes, even at a higher price.



That's not all. Customers who ate a "most popular dish" rated it 8.3% tastier than those who ate the same dish but weren't told it was popular.

How it's applied

Ballantine's Ale didn't promote itself as "Fresh. Delicious. Beer".

Instead, they simply said "America's Largest Selling Ale" and probably saw a jump in sales (and satisfaction).

I like the Ballantine ad, but I don't love it.

It's uncreative and in your face. We don't like to be sold to, and we're more persuaded by less invasive attempts to showcase popularity.

Tunnocks, for example, don't call themselves the most popular Scottish-made bar.

Instead, they simply write the number of bars sold each week on the back of the packet.

An even better example comes from this 1964 full-page Kellogg ad.

The ad doesn't say that Pop-Tarts are best-selling.

It apologises for running out of supply.

"We had no idea our Pop-Tarts would become so popular—so soon."
"We haven't been able to keep up."
"If your store is temporarily out of Pop-Tarts, please forgive us. They'll have some more shortly."

It's achieving exactly what Ballantine and Pop-Tarts achieve, without making the reader feel sold to.

I think that's the best way to apply social proof.

Labour Looks Smarter Read online Last week I shared one of my unhinged theories with you Many of you rightly pointed out that one study from 2011 is hardly enough to draw lofty conclusions. Fair enough, I've gathered some more evidence. Starting with an imaginary story from my barbers. A good barber is a slow barber Imagine you go to your local barbershop. Your normal barber is on holiday, so you're assigned to someone new. Typically your barber spends 45 minutes cutting your hair. He's not...

Labour Illusion Read online I have a slightly unhinged theory that most websites lie to me. I know you're reaching for the unsubscribe button, wondering how many tin foil hats I can fit on my massive hat, but wait. I have some evidence. In 2025, most of the major LLM models made an almost identical update. Claude, ChatGPT, Gemini and many others started to show what they were thinking. What Claude told me when I asked it if websites were lying to me. According to Claude, Anthropic does this...

Ibrahimovic's kids join AC Milan and Swede, 40, could stay as a coach when  he FINALLY retires

Prove Your Dedication Read online Imagine your hometown football club booked Swedish legend Ibrahimovic to host a 2-hour training session with local children. That’s what 113 participants at the Stockholm School of Economics were asked to imagine in 2017¹. But there was a catch. Half were told the club spent almost no time persuading Ibrahimovic, with the manager saying: "It's fantastic that it was so easy to persuade you to come." The others were told booking Ibrahimovic took extreme...
