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 both sums.

So, why were the estimates so dramatically different?

Well, it's due to anchoring.

Anchoring = we attach far greater significance to the first few numbers.

In his brilliant book Consumerology¹, Graves writes that the same principle applies to words.

One study asked participants to read one of these two sentences and quickly decide who they'd like more:

John is intelligent, industrious, impulsive, critical, stubborn, and jealous.

Mark is jealous, stubborn, critical, impulsive, industrious, and intelligent.

The words used to describe both are identical, yet perceptions changed.

Readers were heavily influenced by the first word and said they'd prefer John.

Richard Shotton, in his fantastic book², applied this finding to ads.

He showed one of the following ads to two separate groups.

Those who read the positives first ranked the ad 11% higher.

So, are you leading with your best benefit?

The Nature Effect Read online Are you happier outside? In one 2013 study¹ one million iPhone notifications were sent to 20,000 Brits at various times of day, over a six-month period. The app prompted participants to report their happiness. The app used in the study The phone's GPS determined if the participant was outside or inside. Turns out, those outdoors were much happier. Compared to those inside, participants outside were "significantly and substantially happier", according to the...

The Framing Effect Read online Many plant-based products are failing due to bad naming. In 2018¹, a study was conducted with 727 Brits who already ate meat. Renaming the “𝐦𝐞𝐚𝐭-𝐟𝐫𝐞𝐞 𝐛𝐫𝐞𝐚𝐤𝐟𝐚𝐬𝐭” to “𝐟𝐢𝐞𝐥𝐝-𝐠𝐫𝐨𝐰𝐧 𝐛𝐫𝐞𝐚𝐤𝐟𝐚𝐬𝐭” made diners 200% more likely to pick the plant-based option. Similarly, renaming “𝐦𝐞𝐚𝐭-𝐟𝐫𝐞𝐞 𝐬𝐚𝐮𝐬𝐚𝐠𝐞 𝐚𝐧𝐝 𝐦𝐚𝐬𝐡” as “𝐟𝐢𝐞𝐥𝐝-𝐠𝐫𝐨𝐰𝐧 𝐬𝐚𝐮𝐬𝐚𝐠𝐞 𝐚𝐧𝐝 𝐦𝐚𝐬𝐡” made it twice as popular. The paper went on to find that a Veggie Burger will be more popular if it’s called a “𝐋𝐨𝐚𝐝𝐞𝐝 𝐁𝐮𝐫𝐠𝐞𝐫”. And...

The Framing Effect Read online Here's a thought experiment. You've been told you have lung cancer. The doctor asks if you want treatment. She tells you: "68% survive one year after surgery" Hearing this, you'd probably opt for surgery, that's what the majority pick¹. But what if the doctor said: "32% die within one year after surgery" Now, if you're like those in this¹ study, you'd be less likely to choose surgery. It's the same odds of survival. But the wording changed behaviour. This is the...
