Associative Learning

​Read online​

I'm reading The Expectation Effect.

On page 52¹, there's a story that every marketer should read:

The surgeon John Noland Mackenzie was among the first to test a negative expectation effect in medicine.
​
Working at Baltimore's Eye, Ear and Throat Charity Hospital in the 1880s, he examined a 32-year-old woman with severe asthma and hay fever.
​
When exposed to pollen, her nose and eyes would run and her throat would itch so badly she felt she must "tear [it] out with her nails."
​
On the worst occasions she suffered hour-long sneezing fits, spent much of the summer in bed, and couldn't keep flowers in the house.
Something about the woman's descriptions led Mackenzie to question whether pollen was really the cause.
​
He acquired an artificial rose "of such exquisite workmanship that it presented a perfect counterfeit of the original," carefully wiped every leaf and petal, then revealed it from behind a screen mid-consultation.
​
Within a minute, her voice was hoarse, her nose blocked, and she had the irresistible urge to sneeze. Her nose and throat were visibly red and swollen.
Once Mackenzie revealed the rose was fake, she had to inspect it closely before she believed him. On her next visit, she buried her nose in a bunch of real roses without a single sneeze.

This story exposes associative learning.

We become conditioned to thinking a product, service (or rose) will deliver a certain output.

For example, we associate the following:

  • Expensive wine = higher quality.
  • Family-run business = more trustworthy.
  • Supermarket own-brand = lower quality.
  • A slow website = cheap.
  • A heavy product = better built.

But marketers can hack into this. Take this hot sauce from the states...

The General's Hot Sauce probably tastes hotter because it's served in a grenade.

People globally associate a grenade with explosives. Which is why hot sauce served in a grenade shell tastes spicier.

Charles Spence² writes about associative learning in Sensehacking. He explains how loud cars really do seem like they're driving faster.

One 2011 study found that participants thought a louder car was driving 10% faster than a quieter car travelling at the exact same speed.

We associate noise with speed. And grenades with power.

The General's Hot Sauce could spend thousands of pounds tracking down even hotter chillis, or they could simply put their sauce in a grenade. Both have the same effect.

Generation Effect Read online This ad outside my local opticians sticks in my mind. "Blink if you need an eye exam." At first glance, it's bizzare. It doesn't promote the business, showcase a promotion, or entice people in. And yet, I think it's weirdly effective due to the generation effect. In 1978, researchers¹ asked participants to either read work pairs or generate missing words from cues. For example: Read condition: hot → cold Generate condition: hot → c___ Those generating answers...

Isolation Effect Read online Noah Kagan tested his book cover design by photoshopping the book onto shelves to see what stood out. The green cover isn't different, but it is distinct. In 1933, German researcher Hedwig Von Restorff¹ published a paper on memory and distinctiveness. She gave participants long lists of letter combinations to remember (e.g. JTSW, UCSM, PLST), but among them was a single number sequence: 9125. When participants returned after a distraction task, Hedwig found that...

Social Proof Read online "Window cleaning in progress" I love this board because it remembers something most marketers forget. A real photo taken on a suburban street in Houston. Cialdini proved that we're persuaded by others. In an Arizonan hotel room, he placed two messages on hotel doors designed to convince guests to reuse their towels. “Help us save the environment” = 35% towel reuse. “Most guests reuse their towels” = 44% towel reuse. We're persuaded by others' actions. So, if a...
