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.

Transparency Read online For his book Influence, Robert Cialdini went undercover as a waiter at a high-end restaurant. He spent his time shadowing Vincent, who consistently received the largest tips. Turns out, Vincent had a counterintuitive tactic. When it was time for the first person, normally a woman, to order, he went into his act. No matter what she picked, Vincent reacted identically: his brow furrowed, his hand hovered above his order pad, and after looking quickly over his shoulder...

Pratfall Effect Read online A few years back I received this review. It hurt me a bit and knocked my confidence. I was desperate for listeners to leave some positive reviews so others wouldn't see it. I tried to cover it up, but other brands do the opposite. Spa Diner promotes "the worst breakfast one man on Yelp ever had". Snowbird put their 1-star review in a double-page magazine ad. The Antelope pub share their negative reviews on Facebook. This sandwich shop printed out their 1-star...

The Issue With AI Read online There's a community on Reddit where users debate if an image is AI-generated. This image was subject to fierce debate. Turns out it is AI-generated. This is an AI pizza. In the comments, most users say they'd stop visiting a restaurant that used AI in its photos. Another user shared an example of their local pizza joints doing the same. Sarno forgot to erase the Papa John's logo from their AI pizza. Reddit users hate these AI images. One commenter said: "this...
