No flashes of lightning illuminated my laboratory; nor was there a baying of the hounds on the moor. But this was still a good day for science. By the time I was through, I had the MIT equivalent of George Clooney in his prime (A) and the MIT equivalent of Brad Pitt in his prime (B), and also a George Clooney with a slightly drooping eye and thicker nose (−A, the decoy) and a less symmetrical version of Brad Pitt (−B, another decoy). I followed the same procedure for the less attractive pairs. I had the MIT equivalent of Woody Allen with his usual lopsided grin (A) and Woody Allen with an unnervingly misplaced eye (−A), as well as Danny DeVito (B) and a slightly disfigured version of Danny DeVito (−B).
For each of the 12 photographs, in fact, I now had a regular version as well as an inferior (−) decoy version. (See the illustration for an example of the two conditions used in the study.)
It was now time for the main part of the experiment. I took all the sets of pictures and made my way over to the student union. Approaching one student after another, I asked each to participate. When the students agreed, I handed them a sheet with three pictures (as in the illustration here). Some of them had the regular picture (A), the decoy of that picture (−A), and the other regular picture (B). Others had the regular picture (B), the decoy of that picture (−B), and the other regular picture (A).
For example, a set might include a regular Clooney (A), a decoy Clooney (−A), and a regular Pitt (B); or a regular Pitt (B), a decoy Pitt (−B), and a regular Clooney (A). After selecting a sheet with either male or female pictures, according to their preferences, I asked the students to circle the people they would pick to go on a date with, if they had a choice. All this took quite a while, and when I was done, I had distributed 600 sheets.
What was my motive in all this? Simply to determine if the existence of the distorted picture (−A or −B) would push my participants to choose the similar but undistorted picture. In other words, would a slightly less attractive George Clooney (−A) push the participants to choose the perfect George Clooney over the perfect Brad Pitt?
There were no pictures of Brad Pitt or George Clooney in my experiment, of course. Pictures (A) and (B) showed ordinary students. But do you remember how the existence of a colonial-style house needing a new roof might push you to choose a perfect colonial over a contemporary house—simply because the decoy colonial would give you something against which to compare the regular colonial? And in the Economist's ad, didn't the print-only option for $125 push people to take the print-and-Internet option for $125? Similarly, would the existence of a less perfect person (−A or −B) push people to choose the perfect one (A or B), simply because the decoy option served as a point of comparison?
Note: For this illustration, I used computerized faces, not those of the MIT students. And of course, the letters did not appear on the original sheets.
It did. Whenever I handed out a sheet that had a regular picture, its inferior version, and another regular picture, the participants said they would prefer to date the “regular” person—the one who was similar, but clearly superior, to the distorted version—over the other, undistorted person on the sheet. This was not just a close call—it happened 75 percent of the time.
To explain the decoy effect further, let me tell you something about bread-making machines. When Williams-Sonoma first introduced a home “bread bakery” machine (for $275), most consumers were not interested. What was a home bread-making machine, anyway? Was it good or bad? Did one really need home-baked bread? Why not just buy a fancy coffee-maker sitting nearby instead? Flustered by poor sales, the manufacturer of the bread machine brought in a marketing research firm, which suggested a fix: introduce an additional model of the bread maker, one that was not only larger but priced about 50 percent higher than the initial machine.
Now sales began to rise (along with many loaves of bread), though it was not the large bread maker that was being sold. Why? Simply because consumers now had two models of bread makers to choose from. Since one was clearly larger and much more expensive than the other, people didn't have to make their decision in a vacuum. They could say: “Well, I don't know much about bread makers, but I do know that if I were to buy one, I'd rather have the smaller one for less money.” And that's when bread makers began to fly off the shelves.2
OK for bread makers. But let's take a look at the decoy effect in a completely different situation. What if you are single, and hope to appeal to as many attractive potential dating partners as possible at an upcoming singles event? My advice would be to bring a friend who has your basic physical characteristics (similar coloring, body type, facial features), but is slightly less attractive (–you).
Why? Because the folks you want to attract will have a hard time evaluating you with no comparables around. However, if you are compared with a “–you,” the decoy friend will do a lot to make you look better, not just in comparison with the decoy but also in general, and in comparison with all the other people around. It may sound irrational (and I can't guarantee this), but the chances are good that you will get some extra attention. Of course, don't just stop at looks. If great conversation will win the day, be sure to pick a friend for the singles event who can't match your smooth delivery and rapier wit. By comparison, you'll sound great.
Now that you know this secret, be careful: when a similar but better-looking friend of the same sex asks you to accompany him or her for a night out, you might wonder whether you have been invited along for your company or merely as a decoy.
RELATIVITY HELPS US make decisions in life. But it can also make us downright miserable. Why? Because jealousy and envy spring from comparing our lot in life with that of others.
It was for good reason, after all, that the Ten Commandments admonished, “Neither shall you desire your neighbor's house nor field, or male or female slave, or donkey or anything that belongs to your neighbor.” This might just be the toughest commandment to follow, considering that by our very nature we are wired to compare.
Modern life makes this weakness even more pronounced. A few years ago, for instance, I met with one of the top executives of one of the big investment companies. Over the course of our conversation he mentioned that one of his employees had recently come to him to complain about his salary.
“How long have you been with the firm?” the executive asked the young man.
“Three years. I came straight from college,” was the answer.
“And when you joined us, how much did you expect to be making in three years?”
“I was hoping to be making about a hundred thousand.”
The executive eyed him curiously.
“And now you are making almost three hundred thousand, so how can you possibly complain?” he asked.
“Well,” the young man stammered, “it's just that a couple of the guys at the desks next to me, they're not any better than I am, and they are making three hundred ten.”
The executive shook his head.
An ironic aspect of this story is that in 1993, federal securities regulators forced companies, for the first time, to reveal details СКАЧАТЬ
