Veblen Goods 
Details
Veblen Goods are products people want more when they cost more. The high price doesn’t just signal quality, it creates desire by signaling status.
Think of a limited-edition luxury watch that becomes even more wanted after its price increases. The higher cost makes ownership rarer and more visible, so demand rises instead of falling.
In marketing, this effect appears in categories where status, visibility, and exclusivity matter more than utility. For these products, lowering the price would actually reduce their appeal.

Research
The research from 2018 shows when higher prices increase demand, and when they stop working. The author ran 8 controlled experiments using real luxury products (watches, trench coats, travel bags, champagne). Prices were raised by ~6% (low) and ~11% (high), which matches real luxury pricing (~3-10% per year, confirmed by experts). Results depend entirely on the motivation for why people buy.
Overall conclusion:
Price increases of ~6-11% raise demand only when price clearly signals status or exclusivity. Above this range, the effect often disappears and demand returns to normal (higher price >> lower demand). Price works only as a social signal, not as a cost, quality test, or pleasure tax.

Examples
1. Hermès Birkin
Birkin bags officially start around $10,000-$12,000, but rare versions resell for $50,000-$500,000+, which only increases demand and status signaling. The difficulty and price make the bag a status symbol. People want it because most people can’t afford it.
Supreme sells basic items (T-shirts, bricks, crowbars) at very high prices. The price itself signals cultural status and insider knowledge. Cheap Supreme would not be Supreme.
Prestige Pricing Details
Prestige Pricing means setting a clearly higher price than the rest of the market to signal quality, status, and exclusivity. The price is not just a number, it’s part of the positioning.
This strategy works when the gap is obvious. Think of supermarket chocolate bars priced around $2.99-3.99, while a small artisan brand sells a bar for $15.00, shown as a clean, rounded price. The chocolate may look similar at first glance, but the high price instantly signals rarity, craftsmanship, and premium ingredients. You understand it’s a different category before tasting it.
Prestige Pricing is usually displayed with clean, rounded numbers, not 1.99 or 2.49. Rounded prices feel confident and deliberate. Rounding alone doesn’t create prestige, but it protects the premium signal once the price is clearly higher.
In marketing this approach is used by luxury and artisan brands that avoid discounts and price tricks. The price itself communicates status and quality.

In a wine tasting study, researchers told people they were sampling two wines:
but it was actually the same wine.
Participants reported the “$45” wine tasted better, and their brain’s pleasure center showed more activity when drinking it. In essence, a higher price created an expectation of quality that literally enhanced the experienced quality.
Prestige Pricing Examples
1. Apple Watch Edition
Apple sold the Apple Watch Edition in solid gold for $15,000-$17,000, even though it worked almost the same as the regular Apple Watch. The high price was not about features, it was about status, exclusivity, and luxury signaling.

Rolex watches are expensive and hard to get. The price tells others you are successful and serious, even before they know the model. Lowering the price would actually damage the brand.
Evolutionary and Social NeedsDetails
Evolutionary and Social Needs means our behavior is still shaped by ancient drives: staying safe, fitting in, gaining status, and protecting our group. Modern choices often come from these old instincts.
This is where the 6 Human Needs (by Tony Robbins) help explain what people want to feel:
The biggest companies in the world help people satisfy these deep needs. Apple gives status and belonging. Nike taps into identity and achievement. Tinder taps into mate selection and social connection. These brands grow because they align with instincts that have guided humans for thousands of years.
When a product taps into these deep human needs, people respond faster and feel more emotionally pulled.
In other words, we still act like social animals, and there's nothing wrong about it.
Evolutionary and Social Needs Guide
Evolutionary and Social NeedsResearch
Every buying decision is driven by 6 psychological needs, not logic. Products, services, and brands are just vehicles people use to meet emotional needs. If one brand satisfies 3+ needs, people become highly loyal or even addicted.
Each person has the top 2 needs, and those needs shape their identity - why they buy, why they churn, and what messaging works.

1. Trends by Sam Parr
Trends sold yearly membership with the most recent trends reports, but the real value became their private Facebook community, where entrepreneurs supported each other every single day.
This same insight powers Sam Parr’s new venture, Hampton, built entirely around curated tribe-based belonging for founders.
Strava is no longer just an app for tracking runs. It has become a quiet social hub where people join groups, share workouts, and support each other.
Scarcity Details
Scarcity means we value things more when they feel limited. When supply drops, desire rises, even if nothing else changes.
Think of seeing only a few items left on a shelf. Suddenly the product feels more important, even if you didn’t want it a minute ago. The fear of losing it boosts the urge to act.
In marketing scarcity turns hesitation into action. Limited spots, low stock, and short windows make people move faster because waiting feels risky.
Scarcity Guide
ScarcityResearch
A large meta-analysis of 131 studies and 416 effects found that not all scarcity works the same.
A group of 200 female students rated how attractive cookies were when there were many of them (abundant), when there were few (scarce), and when the amount changed. When cookies became scarce, the students were told it happened either because many people wanted them or because of an accident.
As a result, the cookies were rated more desirable when they were scarce than when they were abundant.
They were also rated more valuable when they changed from abundant to scarce compared to being scarce the whole time.
Scarcity caused by high demand got the highest ratings, while “accidental scarcity” scored lower. And cookies that stayed abundant the whole time were rated higher than cookies that started scarce and later became abundant.
Scarcity Examples
When Snap released Spectacles, you could only buy them from special vending machines called Snapbots. They appeared in random places without warning, so it felt like a surprise game of first come, first served.
This unpredictable availability created strong FOM and as a result, Spectacles became a cult gadget.
MSCHF releases strange products in small, surprise drops. You never know when the next drop comes, and they never restock, so people rush to buy. This makes every product feel rare, special, and worth grabbing fast.
TBH launched only in a few high schools and only in one state at the start, nobody else could download it. This created massive FOMO in nearby schools. Because of that (and many other brilliant aspects), the app was downloaded 5M times within 2 months.
Noble Edge Effect Details
Noble Edge Effect means a brand looks even better when it does something good and can show it wasn’t just for profit. When motives seem pure, the positive impression grows stronger.
Think of a company donating part of its revenue to a cause and being fully transparent about where the money goes. People rate the brand as more trustworthy and higher-quality, not because the product changed, but because the intention behind it feels honest.
In marketing this bias boosts brands that show real ethics, responsible sourcing, or community impact. When customers sense sincerity instead of PR polish, loyalty goes up.
Noble Edge Effect Guide
Noble Edge Effect Research
In the study, participants drank the same wine but rated it very differently depending on the label. When the label said the company gives part of its profits to charity, people said the wine tasted better and judged its quality higher, raising taste ratings by 19-25% and overall value and willingness-to-pay by 10-15%.
The effect stayed strong even when the product was objectively bad (like bitter chocolate), meaning charity created a halo that changed the actual sensory experience.
But this only worked when the charity action looked truly altruistic, not self-serving.
Noble Edge Effect Examples
1. Patagonia
Patagonia is famous for openly putting the environment above profit - repairing clothes, recycling materials, donating profits, and encouraging people to buy less. Because these actions look costly for a premium brand, customers trust them more and feel the high prices make sense.
Lordicon publicly promises to donate $1 out of every $10 profit to help people in need. This donation is costly for the company and not required, which makes customers trust the brand’s intentions more.
Reactance Bias Details
Reactance Bias means we push back when we feel our freedom is being limited. The moment something feels forced, restricted, or taken away, we want to do the opposite.
Think of someone telling you not to look at a message, and suddenly you feel an even stronger urge to check it. The resistance comes from the feeling of lost control, not from the message itself.
In marketing this bias shows up when brands overpressure people with hard sells, forced choices, or aggressive pop-ups. The more control customers feel they’re losing, the more they resist and leave.
Reactance Bias Guide
Reactance Bias Research
In 1976, Pennebaker and Sanders tested how people react when someone tells them what to do. They put two different signs in college bathrooms to stop graffiti.
After a few weeks, the bathrooms with the strict sign had way more graffiti. The harsh tone made people want to do the opposite.
Heavy, scary anti-smoking ads “smoking will kill you!” actually made some teens smoke more.
But the Truth campaign did the opposite. It showed how Big Tobacco lies and tricks people. The message was basically “don’t let them control you.”
Teens could still rebel, just against the tobacco companies, not the health message.
That approach worked. Youth smoking dropped by 22% in two years.
Reactance Bias Examples
1. Dumb Ways to Die
The Dumb Ways to Die campaign used reactance bias by making dangerous behaviour look stupid, not forbidden. People don’t like being told what to do, but they really don’t want to be seen as idiots. So instead of saying “don’t go near trains,” the campaign showed goofy characters dying in ridiculous, dumb ways.
Patagonia literally told customers not to buy their jacket in a famous ad. The reverse psychology triggered reactance in the opposite direction: when a brand says “don’t,” people suddenly feel more drawn to the product. Sales spiked because the message felt non-pushy and gave customers a sense of autonomy.
