To protect your budget while shopping, be aware of the sneaky tricks that will trigger your urge to buy. Thinkstock By Anne Kates Smith, Executive Editor From Kiplinger's Personal Finance, December 2014 Something to think about while holiday shopping: When it comes to buying, your subconscious mind makes the decision several seconds before your conscious mind is aware of it. In other words, your emotional self does the buying. Your rational self, well, rationalizes. “The unconscious mind decides on the red convertible. The rational mind seeks to explain the decision in terms of good gas mileage,” says Roger Dooley, author of Brainfluence: 100 Ways to Persuade and Convince Consumers with Neuromarketing.

Tools of the trade include eye-tracking technology, electroencephalograms to measure electrical activity in the brain, and functional magnetic resonance imaging, tracking blood flow in the brain to detect areas of activity. But much of the science merely confirms what marketers, advertisers and retailers have known forever: Buyers aren’t convinced; they’re wooed. “You’re entering a zone of seduction as soon as you enter the department store, and the only purpose is to get you to buy more,” says branding guru Martin Lindstrom.

Mannequins never look straight out to the street; they look left or right, the better to make eye contact with you as you walk by. Without realizing it, you feel obliged to stop. Retailers know that your sense of smell is a powerful subconscious motivator. It can trigger cravings, memories or associations that make us linger in a store and influence us to buy. According to the Scent Marketing Institute, we’re likely to browse longer in stores with floral or citrus scents, to feel secure and nostalgic when we smell talcum powder, and to feel relaxed when the scent of lavender or vanilla is wafting. Each piece of department store clothing is tried on an average of nine times, says Lindstrom. So a fresh lemon or grassy scent in the dressing room is meant to distract you from the effects of all who came before you.

You’ll recall the feeling of the good old days without feeling stuck in the past. Lighting in clothing departments will be warm and soft, and the clothing may be “vanisized”—manufactured larger than the size on the tag or than the same size in a competing brand. Your perception of value can be skewed by the “contrast effect,” says marketing professor Dipayan Biswas, of the University of South Florida. A $20 shirt seems like a bargain when it’s placed next to $40 shirts. Even the color of the ink used on sale signs matters: Markdowns in red seem more drastic and therefore more compelling. Tricks of the Trade Are such retail tricks unethical? Not really, says neuroeconomist Paul Zak, of the Center for Neuroeconomic Studies at Claremont Graduate University. “We’re always trying to manipulate people—for example, when we’re dating someone or raising children. That people with a profit motive manipulate us is not surprising,” he says. And many of the practices are what make shopping enjoyable. But you can make sure you don’t sabotage your budget. When you shop, clear your schedule and bring a list. People with a plan tend to spend the least, says Stephen Sands, of neuromarketing firm Sands Research; time-pressured shoppers spend more, and more impulsively. Shop alone. Going with a partner increases spending up to 17%, says Lindstrom; with a friend, it goes up between 7% and 9%. Wait before you buy, whether you take a half-hour break or you go home to sleep on a major purchase decision. That allows the cognitive areas of your brain to engage. Remember, they’re a little slow.
