Lesson 11: Advertising and Impulse Buying
Every day you see hundreds of advertisements — on phones, on videos, on buses, in games and on clothing. Advertising is not a friendly suggestion; it is a multi-billion-unit industry whose job is to make you want things you had not planned to buy. It works because it is designed by people who understand human psychology very well. Knowing how it works does not make you immune, but it does make you harder to manipulate, and that is worth a great deal of money over a lifetime.
Advertisers use a small set of tricks, and once you can name them, you can spot them. Emotional appeal links a product to happiness, friendship, success or belonging — the drink is shown at a party with laughing friends, never alone on a dull afternoon. Social proof suggests that everyone else is already buying it: 'millions sold', influencers holding the product, or crowds rushing to buy. Scarcity creates urgency: 'only two left', 'offer ends tonight', a countdown timer. Repetition simply shows you the same message again and again until the product feels familiar and safe. None of these tricks says anything about whether the product is good value, whether you need it, or whether a cheaper alternative would do just as well.
Impulse Buying
Advertising leads to impulse buying: buying something on the spot, without planning, because a feeling in the moment overwhelms judgement. Shops are designed to encourage it — sweets at the checkout, 'buy one get one free' signs, apps that let you buy with a single tap. The purchase feels small and the pleasure is immediate, while the cost is quiet and delayed. The best defence is time. A simple rule helps enormously: for any unplanned purchase above a small amount, wait 24 hours before buying. If you still want it tomorrow, and you can afford it, buy it — but most impulse buys fail the 24-hour test, because the want was created by the moment, not by a real need. A shopping list also helps: decide what you need before you enter the shop, and buy only what is on the list.
Thinking Like a Sceptic
Before buying anything advertised, ask four questions. Do I need this, or did the advertisement create the want? What does it really cost, including the full price and any extras? Is there a cheaper way to get the same result? And would I still want it if I had not just seen the advertisement? You will still buy things you enjoy — that is fine. The aim is to buy because you chose to, not because a screen told you to. Advertisers spend enormous sums because their methods work; your scepticism is the only counterweight you have, and it is free.

Discussion Questions
- Think of an advertisement you remember well. Which trick did it use — emotion, social proof, scarcity or repetition?
- Why do you think shops put sweets and small items near the checkout? Who benefits?
- Would the 24-hour rule work for you? What kinds of purchases would it change?
Practice Questions
- Name three advertising tricks and explain how each one works.
- What is impulse buying, and why do shops try to encourage it?
- How does the 24-hour rule help against impulse buying?
- Why is a shopping list a useful defence against advertising?
- What four questions should you ask before buying something you saw advertised?
Show answers
- Any three of: emotional appeal (links the product to happy feelings), social proof (suggests everyone else buys it), scarcity (claims it will run out soon), repetition (shows the message until it feels familiar).
- Impulse buying is unplanned buying driven by a feeling in the moment. Shops encourage it — for example with items at the checkout — because unplanned purchases add sales.
- It lets the feeling fade. Most impulse wants are created by the moment; if the want is still there after 24 hours, it is more likely a real want.
- A shopping list fixes your decisions in advance. You buy what is on the list, so advertisements in the shop have less chance to add unplanned items.
- Do I need it or did the ad create the want? What does it really cost? Is there a cheaper way to get the same result? Would I still want it without the ad? Any four sensible questions count.
