Quick, pick one: a 33% discount or 33% more for free …

July 17, 2012

According to a study at the University of Minnesota’s Carlson School of Management, report in The Economist

When offered two deals on loose coffee beans: 33% extra free or 33% off the price, most shoppers considered them equivalent though he discount is by far the better proposition … it would take a 50% increase in quantity to be equivalent.

More generally, the researchers found, that shoppers prefer getting something extra for free to getting something cheaper.

For example, the researchers sold 73% more hand lotion when it was offered in a bonus pack than when it carried an equivalent discount (even after all other effects, such as a desire to stockpile, were controlled for).

The main reason is  “consumer innumeracy” … e.g. people can’t do fractions or simple math in their head.

How can retailers compensate for (or exploit) consumers’ math blind spots?

One way is to befuddle them with double discounting.

People are more likely to think that a product that has been reduced by 20%, and then by an additional 25%, is a better deal than one which has been subject to an equivalent, one-off, 40% reduction.

Similarly, when evaluating a car’s fuel efficiency, consumers understand the number of extra miles per gallon it gets, more so than the equivalent percentage fall in fuel consumption.

We’re not talking calculus, we’re talking fractions … ouch.
