Barnum Effect Read online Why does the ad on the ๐ซ๐ข๐ ๐ก๐ญ capture attention? Well, it might be down to the question.Rohini Ahluwalia and Robert Burnkrant's studyยน in 2004 tested two types of ads. Statement-based ads: "You haven't had a pear in a while."And... Question ads: "When was the last time you had a pear?" The researchers found that ads using questions are rated 14% ๐ฆ๐จ๐ซ๐ž ๐Ÿ๐š๐ฏ๐จ๐ฎ๐ซ๐š๐›๐ฅ๐ฒ than statement-based ads.

The Country-of-Origin Effect Read online Youโ€™re thinking of buying a new pair of running shoes. Usually, you go with Nike. But this time, youโ€™re considering Umbro (a lesser-known brand). Then you find out: Umbro makes their shoes in the UK. Nice. It's always good to find locally made brands. Youโ€™re willing to pay a decent price. But the next day, you hear Umbro are moving production to South Korea. Now, would you still pay the same? Probably not. Thatโ€™s exactly what these researchersยน found....

The Anchoring Effect Read online In the 1970s, Tversky and Kahnemanยน ran a simple experiment. They asked people: "What percentage of African countries are in the UN?" But before answering, participants had to spin a wheel with numbers from 0 to 100. The wheel was rigged to land on either 10 or 65. Then came the important question: "Is the actual percentage higher or lower than that number?" After that, participants gave their best estimate. Hereโ€™s what happened: People who saw 10 guessed 25%...

The Illusion of Choice Read online Give people $1 and two identical packs of gum. Same flavour. Same price. What happens? Most people aren't interested. Thatโ€™s what Kim, Novemsky, and Dharยน found in a South Korean experiment. They gave participants โ‚ฉ1,000 and two gum options, both priced at โ‚ฉ630. Only 46% bought anything. But then they did something clever. They made the prices slightly different: โ‚ฉ620 vs. โ‚ฉ640. Now 77% decided to buy. Same gum. Slight price difference. Big impact. Why? When...

Participants were shown round the same store, except half saw the shelves ๐ง๐ž๐š๐ญ๐ฅ๐ฒ ๐ฌ๐ญ๐š๐œ๐ค๐ž๐ ๐ฐ๐ข๐ญ๐ก ๐ก๐ข๐ ๐ก-๐ž๐Ÿ๐Ÿ๐จ๐ซ๐ญ ๐๐ข๐ฌ๐ฉ๐ฅ๐š๐ฒ๐ฌ.

Concrete Phrases Read online Which electric bus would stick in your mind? It's not even a competition. Copy that's easy to visualise is easy to memorise. In 2021, Richard Shottonยน showed participants a number of vague phrases, like 'innovative quality', and then some concrete phrases, e.g., 'money in your pocket'. Shottonโ€™s concrete phrases were 8.6x more likely to be remembered. Richard Shotton's Concrete Phrases Study Heโ€™d proved the concrete phrases' effect, a phenomenon first discovered...

Psychology of Pricing Read online 1) Charm Pricing for High-Quality Products Imagine youโ€™re buying a shatterproof iPhone case Does it matter if it is priced at ยฃ49.99 or ยฃ49.95? Well, yes. Apple uses charm pricing but usually ends prices with a 5. Gendall, Fox, and Wilton (1998)ยน ran an experiment with fast-moving consumer goods (fly spray, cheese) and durables (electric kettles). They found that prices with endings in 99 cents are more attractive for low-priced, fast-moving consumer goods...

Unit Asking Read online Which of these articles encouraged Brits to donate more? It's the one on the right. Research by Christopher Hseeยน found that donors gave nearly twice as much when first asked to consider the needs of a single person before being asked to donate to a larger cause. This โ€œunit askingโ€ strategy made contributions feel more reasonable and personal. And it explains thisยฒ rather bizarre study: The study looked at the success rate of donation requests on the...

Hyperbolic Discounting Read online One of these ads looks 108% better value. Can you guess which? In 2025, Shotton and Flickerยน tested ads like this in their book. 282 consumers were shown Sierra Nevada Pale Ale priced at $18.99 for 12 bottles. Half were told this equated to $1.58 per bottle. Among those shown the per-bottle price, 28.6% said it was good or very good value (more than double the 13.7% who only saw the total price). Framing the cost at the per-unit level made the purchase feel...

Specific Number Bias Read online Which coaster makes Guinness seem like the โ€˜๐˜ฑ๐˜ฆ๐˜ณ๐˜ง๐˜ฆ๐˜ค๐˜ต ๐˜ฑ๐˜ช๐˜ฏ๐˜ตโ€™? Thatโ€™s what Schindlerยน (Rutgers University) and Yalch (University of Washington) studied in 2006. They showed participants ads that used specific numbers, for example: โ€œIt takes 119.5 seconds to pour the perfect pint.โ€ Vs. rounded numbers: โ€œIt takes 2 minutes to pour the perfect pint.โ€ Turns out, claims made using ๐ฌ๐ฉ๐ž๐œ๐ข๐Ÿ๐ข๐œ ๐ง๐ฎ๐ฆ๐›๐ž๐ซ๐ฌ are perceived to be 10% ๐ฆ๐จ๐ซ๐ž ๐›๐ž๐ฅ๐ข๐ž๐ฏ๐š๐›๐ฅ๐ž.
