Nine marketing examples that tap into cognitive biases

Creative

1/ Alka-Seltzer and The Suggestibility Bias

Alka-Seltzer infamous jingle “plop, plop, fizz, fizz, oh, what a relief it is” reminded customers to take two tablets instead of one. Sales doubled.

2/ Nomad List and The Halo Effect

Nomad List started donating 5% of revenue to remove CO2 from the atmosphere. Conversions increased 200%. Yes. This is unbelievable.

3/ Uber and Our Bias Towards Certainty

Uber's map didn't reduce waiting time but it did make waiting less frustrating. The uncertainty of waiting bothers us more than the duration.

4/ Swedish Blood Banks and The Peak End Rule

When you donate blood in Sweden you get sent a follow up text when your blood’s been used. The happy ending makes us want to do it again.

5/ Rolls Royce and The Anchoring Bias

Rolls Royce favourite exhibition spot is yacht and aircraft shows.

“If you’ve been looking at jets all morning, a £300,000 car is an impulse buy. It's like putting sweets next to the counter” — Rory Sutherland

6/ Peloton and The Sunk Cost Fallacy (Money)

A peloton costs $2000. The subscription costs $39/mo. So, either, you're locked in, or you admit to your spouse you've thrown away $2000.

7/ Ikea and The Sunk Cost Fallacy (Time)

Ikea stores are deliberately placed on the outskirts of cities. The extra effort to get there incentivises customers to make the most of their trip.

8/ Lyft and The Left Digit Bias

Lyft cutting the price of a journey from $15 to $14.99 had the same increase on consumer demand as from $15.99 to $15.

9/ Starbucks and The Cocktail Party Effect

The sweetest sound in any language is our name. So Starbucks stopped calling out the drink and started using the customer's name instead.

These are not my own discoveries. Credit to Rory Sutherland, Richard Shotton, Trung Phan, Product Gems. Four fountains of knowledge.
