A masterclass in persuasion (from two window cleaners) | Nudge Newsletter

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...

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...

The Mere Exposure Effect Read online Take a look at this image. What do you see? Taken from Robson's brilliant book The Expectation Effect¹ This is a real image, but it's bleached and poor quality. Chances are, you can't spot what this is. Have another look. Spotted anything? I imagine it's still a no. However, if I tell you to look for a cow, you might see the image differently. As Robson¹ writes: Something somehow “clicks,” and the image suddenly makes a lot more sense. Let's try another...

The Faith Effect Read online Watch an England football match and you'll see a lot of praying. Madueke, Toney, Guehi, Rashford and Saka from left to right. How many players are religious? Well, the evidence is thin. The Telegraph¹ confirms that at least four players are openly Christian. And Woman Alive² (a slightly less reputable source) claims as many as 50% of the team follow a god—higher than the UK average. Regardless of the true number, if you watch England, you'll see a lot of praying....

The Authority Bias Read online Here are some not-so-surprising stats. 20% of trades on the stock market are from brokers copying other profitable brokers¹. 60% of traders say they started trading by copying expert online². But do these financial experts really know more than the rest of us? That's what Richard Wiseman looked at in his great book, Quirkology. Investors vs Chimp Back in 1994, a Swedish newspaper ran a light-hearted experiment. The newspaper gave $1,250 each to five experienced...

Disrupt Then Reframe Read online In his fantastic book 59 Seconds, Richard Wiseman¹ explains the “disrupt, then reframe” approach. The tactic briefly jolts someone out of autopilot with something unexpected, then follows with a straightforward request. In several experiments, researchers went door to door selling notepads for charity. The salesman would either say: 1️⃣ “They sell for $3. It’s a bargain.” 2️⃣ Or, they would introduce a small disruption: “They sell for 300 pennies — that’s $3....

Sharing Weaknesses Read online In the 1970s, researchers Jones and Gordon¹ from Duke University played people a recording of a man (really a stooge) talking about his life. During the tape the man explained he had not completed a school semester because he had been caught cheating and had been expelled. The researchers edited the tape so that: 1️⃣ Half of the participants heard this bombshell toward the beginning 2️⃣ Half of the participants heard it toward the end. Did the timing of the...

Mystery Effect Read online I submit a gas and electricity reading every month. Not because I'm diligent or disciplined. But because my supplier (Octopus Energy) nudges me to do so. Every time I leave a gas reading, they let me spin a wheel to win a potential reward. Most suppliers just ask for a reading (left). Octopus offer a chance to win (right). I've shared this before, but I haven't shared much evidence as to why it works. So, take a look at these images from a 2022 study¹.Which would...

Long-Term Goals = Success? Read online You've probably heard of the “Yale Goal Study". Here's the study. In 1953, researchers interviewed Yale’s graduating class. They asked a simple question: “Have you written down your goals for life?” Twenty years later, they tracked the same students down. And discovered something dramatic. Just 3% had written specific goals. And that 3% had built more personal wealth than the other 97% combined. It’s a perfect self-help story, with a simple lesson. Make...

Commitment Devices Read online Often we plan to do something and don't. Donating blood, going on a run, watching that webinar. We want to, but forget. This drives marketers insane. People sign up for their events—but no one comes. Katy Milkman, a brilliant professor at the Wharton School at the University of Pennsylvania, found a solution¹. She used a commitment device. Milkman and her colleagues teamed up with a large American utility firm to see if they could prompt more of the company's...
