The Ringelmann Effect Read online In 1882, French engineer Maximilien Ringelmann studied effort.ยน He measured how much weight each man could pull. Individually, the men could pull 85 kg. But in groups of seven, they averaged just 65 kg, a 24% drop. This became known as the Ringelmann Effect. Put simply, it proved that as group size increases, individual effort decreases.

The Effort Illusion Read online In 2003, two researchersยน proved the illusion of effort. It means we value things more if we believe it took a lot of time to create. Chinander and Schweitzer had groups watch identical presentations. Groups were told one of two things: "This presentation took 8 hours and 34 minutes to prepare." "This presentation took 37 minutes to prepare." Those told the presentation took longer to prep rated it significantly higher. Can I prove this works? On Nudge, I like...

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 pickยน. But what if the doctor said: "32% die within one year after surgery" Now, if you're like those in thisยน study, you'd be less likely to choose surgery. It's the same odds of survival. But the wording changed behaviour. This is the...

AI + Psychology Read online Thereโs a 2023ยน study I think of whenever I read about AI. The scientists ran four experiments and found that social proof massively improved AI suggestions. For example, people were: 17.6% more likely to buy a pair of sneakers when the AI explained, โItโs the most purchased item.โ To me, it showed that to succeed, AI needs to understand human psychology. And if youโre working with AI, so do you. Adobe's London Summit Adobe was kind enough to invite me to their...

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...
