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.

In fact, studies suggest that smells too faint to consciously detect influence us.

Researchers at Northwestern University² asked students to sniff three scents at such low concentrations that the students were unaware of having smelled anything.

Next, the students were shown a picture of a face with a neutral expression and asked to judge its likability.

It turns out that the type of smell influences likability.

Two real-world examples

Nike shoe sales

Researchers purchased a brand new pair of Nike running shoes.

They were placed in one of two rooms:

  1. A room flooded with a light floral smell
  2. An identical room with no smell

Those in the flower-scented room said they were 84% more likely to buy.*

Casino slot machines

In another study cited in Consumerology, researchers pumped a similar scent into one part of a casino.

Those who gambled in that specific part of the casino gambled 45% more.

​

I no longer feel so ashamed about my Subway secret.

Smells affect all of us, even if we're not consciously aware.

*I strongly doubt a smell could have that big of an effect. And I doubt you could replicate it at your own company.

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

The Anchoring Effect Read online Let's start with an experiment. Consider the following two calculations and attempt to guess the answer. Don't use a calculator, take 10 seconds, and make your guess. 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 = ? 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = ? What did you guess? Were your guesses different? The average guess for the first sum is 512, for the second it's 2,250 (4x higher). Many of you will have figured out that the actual answer is exactly the same. It's 40,320 for...

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.

"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...
