Marketers often exploit cognitive shortcuts, known as heuristics, to convince consumers to make purchases. One example of this is the anchoring bias, or the brain’s tendency to rely heavily on the first piece of information it learns. A savvy marketer may say, for instance, that a car costs $20,000, then quickly offer to take $1,000 off. Since the consumer “anchored” on to the initial $20,000 price tag, a $1,000 discount seems substantial and the consumer may leap at the offer. But if the car was truly worth $15,000, it would still be overpriced, even with the supposed discount factored in.
