   SubliminaI(隐性)advertising happens every day. Shoppers are regularly encouraged to buy by appeals to their senses or unconscious assumptions. I recently carried out a series of research experiments to uncover the ways advertisers use to confuse us to Pull out our wallets. Here are several techniques you should know about.

We fall for "tradition". Some people believe that squeezing a lime(酸橙) into a Corona beer is a time-honored Mexican custom to improve the beer's taste or destroy bacteria(细菌). The truth? It dates back only t0 1981, when a bartender (酒保) threw a lime into the neck of a Corona to see if he could start a trend. This simple act, which caught on like wildfire, helped Corona become the best -selling imported beer in the U.S. market.

Music makes us buy. Store owners know that playing music with a beat faster than the human heartbeat causes shoppers to shop quickly and therefore buy less. The slower the beat, the more time shoppers will take, and the greater the chances are that they'll buy something.

Shapes have a draw. A large food maker once tested two different containers holding exactly the same. The only difference?  Shapes .When asked which product they preferred, every one selected the first bottle that is narrow around the middle and thicker at the top and on the bottom.      

Places help decide. Let's say I offered you a choice of two new cars. They're of the same model, the same color, and they have the same parts. There's only one difference: One is made in  Turkey, and the other in Germany. My guess is that you'd pick the German model, since you associate Germany with superb techniques.
