What would you do in this case? Would you buy this barbecue grill or
drive to another store to look at others? Wait until you have an answer and
then read on.
If you’re like most people, scenario A looked pretty good. One hundred
dollars off a barbecue grill and it’s a model you like? Seems like a good
deal. You probably said you’d buy it rather than keep looking.
Scenario B, however, probably didn’t look so good. After all, it’s only
fifteen dollars off, nowhere near as good as the first deal. You probably said
you’d keep looking rather than buy that one.
I found similar results when I gave each scenario
to one hundred different
people. While 75 percent of the people who received scenario A said they’d
buy the grill rather than keep looking, only 22 percent of people who
received scenario B said they’d buy the grill.
This all makes perfect sense—until you think about the final price at each
store. Both stores were selling the same grill. So if anything, people should
have been more likely to say they would buy it at the store where the price
was lower (scenario B). But they weren’t. In fact, the opposite happened.
More people said they would purchase the grill in scenario A, even though
they would have had to pay a higher price ($250 rather than $240) to get it.
What gives?
THE
PSYCHOLOGY OF DEALS
On a cold, wintry day in December 2002, Daniel Kahneman walked onstage
to address a packed lecture hall at Sweden’s Stockholm University. The
audience was filled with Swedish diplomats, dignitaries, and some of the
world’s most prominent academics. Kahneman was there to give a talk on
bounded rationality, a new perspective on intuitive judgment and choice. He
had given related talks over the years, but this one was slightly different.
Kahneman was in Stockholm to accept the Nobel Prize in Economics.
The Nobel Prize is one of the world’s most prestigious awards and is
given to researchers who have contributed great insight to their disciplines.
Albert Einstein received a Nobel Prize for his work on theoretical physics.
Watson and Crick received a Nobel in medicine for their work on the
structure of DNA. In economics, the Nobel Prize is awarded to a person
whose research has had a large impact on advancing economic thinking.
But Kahneman isn’t an economist. He is a psychologist.
Kahneman received the Nobel for his work with Amos Tversky on what
they called “prospect theory.” The theory is amazingly rich, but at its core,
it’s based on a very basic idea. The way people actually make decisions
often violates standard economic assumptions about how they
should make
decisions. Judgments and decisions are not always rational or optimal.
Instead, they are based on psychological principles of how people perceive
and process information. Just as perceptual processes influence whether we
see a particular sweater as red or view an object on the horizon as far away,
they also influence whether a price seems high or a deal seems good. Along
with Richard Thaler’s work, Kahneman and Tversky’s research is some of
the earliest studying what we now think of as “behavioral economics.”
—————
One of the main tenets of prospect theory is that people don’t evaluate
things in absolute terms. They evaluate them relative to a comparison
standard, or “reference point.” Fifty cents for coffee isn’t just fifty cents for
coffee. Whether that seems like a fair price or not depends on your
expectations. If you live in New York City, paying fifty cents for a cup of
coffee seems pretty cheap. You’d chuckle at your good luck and buy coffee
from that place every day. You might even tell your friends.
If you live in rural India, though, fifty cents might seem hugely
expensive. It would be way more than you would dream of paying for
coffee and you’d never buy it. If you told your friends anything it would be
your outrage at the price gouging.
You see the same phenomenon at work if you go to the movies or the
store with people in their seventies or eighties. They often complain about
the prices. “What?” they exclaim. “No way am I paying eleven dollars for a
movie ticket. That’s such a rip-off!”
It might seem that old people are stingier than the rest of us. But there is
a more fundamental reason that they think the prices are unfair. They have
different reference points. They remember the days when a movie ticket
was forty cents and steak was ninety-five cents a pound, when toothpaste
was twenty-nine cents and paper towels cost a dime. Because of that, it’s
hard for them to see today’s prices as fair. The prices seem so much higher
than
what they remember, so they balk at paying them.
Reference points help explain the barbecue grill scenarios we discussed a
few pages ago. People use the price they expect to pay for something as
their reference point. So the grill seemed like a better deal when it was
marked down from $350 to $250 rather than when it was discounted from
$255 to $240, even though it was the same grill. Setting a higher reference
point made the first deal seem better even though the price was higher
overall.
Infomercials often use the same approach.
