"I'm A Student Here Too"

Read online


In 1994¹, researchers asked 100s of college students for charitable donations.

All were told to interrupt the students and solicit a donation.

But there was a twist.

Half were told to make a straightforward request, with no extra commentary.

Half were told to emphasise a shared identity, saying "I'm a student here too".

The results were astonishing.

Only 9.8% of students in the control group made a donation.

While 47.1% donated in the variant group, a 3x increase.

The takeaway is clear.

To persuade, emphasise what you have in common.

Three real-world examples

1/ Charing Cross Broadband

Richard Shotton² discovered a simple way to make a billboard more memorable.

Make it location-specific.

In his studies, a nationwide billboard for broadband is largely forgotten.

Tailor it for the train station the reader is in (Charing Cross), and awareness increases by 14%².

2/ Costa Coffee

Costa, didn't say "most British people love our coffee".

They personalised it to "coffee lovers".

3/ Jiff

Mothers don't pick Jiff.

Choosy mothers do.

As a behavioural science practitioner, I believe in the peak-end rule.

The Psychology Of Smell Read online I've got a shameful secret. My mouth salivates when I walk past Subway. I know the food is dire, the lettuce is plastic, and the bread is like a sponge. Yet I can't help but feel an urge to go in. After reading Consumerology¹, I think I've learnt why. The Psychology of Smell You'll smell a Subway before you see it. The yeasty, sweet, toasty smell is pumped out onto the street. And I think it's on purpose. Just looking at this image reminds me of the smell....

Losses Feel Worse Than Gains Read online Kahneman proved that "𝘭𝘰𝘴𝘴𝘦𝘴 𝘧𝘦𝘦𝘭 𝘵𝘸𝘪𝘤𝘦 𝘢𝘴 𝘱𝘢𝘪𝘯𝘧𝘶𝘭 𝘢𝘴 𝘦𝘲𝘶𝘪𝘷𝘢𝘭𝘦𝘯𝘵 𝘨𝘢𝘪𝘯𝘴". So, Nationwide don't say:❌ "We've kept our Holloway store open. So you can keep banking in-person."They say:✅ "Santander is leaving Holloway. Maybe it's time you left Santander." It's the best ad I've seen in weeks because it concretely applies behavioural science. Highlighting what a customer will lose is often more persuasive¹ than highlighting what they'll gain.

Placebos And Marketing Read online From December 2007 to January 2012, 146 men participated in an eye-opening study¹. All men had persistent knee pain. All had visited public hospitals in Finland and asked for help. Here's where the study started. Half underwent arthroscopic partial meniscectomy (removal of damaged meniscus tissue). That's the appropriate treatment. The other half underwent sham surgery (anaesthesia and incisions but no tissue removed). It was a placebo surgery. The sham...
