Advertising and consumer choice — Economics, 7–10 years
Advertising gives information about products, but it also tries to influence what people notice, want and buy.
Messages that persuade
Advertising is a message paid for by someone who wants people to notice a product, service or idea. It may show what the product does, but it often uses colours, music, stories or famous people to make it memorable. It can inform us and persuade us at the same time.
Why advertise?
A seller may have a useful product, but people cannot buy it if they do not know it exists. Advertising helps sellers find customers and helps customers hear about choices. Because the seller pays for the message, it is wise to ask what information is missing as well as what is being shown.
Checking a cereal advert
An advert says a cereal box costs €3 and is “20% bigger”. First compare the amount: an ordinary box has 400 g, so 20% more is 80 g and the new box has 480 g. Then calculate the price per 100 g: €3 ÷ 4.8 = €0.625. The exciting claim is not the same as proof of good value.
The trap: believing every claim
It is reasonable to trust an advert because it looks polished and may show a real feature. The trap is treating a slogan such as “the best” as if it were a measured fact. Check the small print, compare quantities and prices, and remember that a picture can show an ideal result.
Where you see it
You meet advertising in videos, games, websites, shops, posters and the packaging of food. Some adverts are easy to spot; others look like advice from a creator or a game reward. Knowing this helps you pause, identify who wants your attention and choose using more than the message alone.
