Predictably
Irrational The
Hidden Forces That Shape Our Decisions Dan

Ariely is a professor of behavioral economics at Duke University. On the basis of many behavioral experiments
and anecdotes (some amusing and some disgusting), Ariely
describes how our decisions are systematically and predictably different from
supposed rational judgments.
Expectations, emotions, social norms, and other seemingly illogical
forces influence our behaviors. Understanding
how we tend to operate can help us make better decisions. Chapter 1. The Truth about
Relativity Everything is relative – even when it shouldn’t
be. Marketers offer a “decoy” offer,
one they don’t expect us to buy, but which helps move us up to a higher level
purchase by making it look like a better deal. Here’s an example of a web subscription
offer to The Economist. On-Line - $59 Print - $125 Print & Web
- $125 Since the person is reading the ad on-line, he
would probably tend toward the cheaper on-line subscription. He notices the print edition, which he
doesn’t need or want to pay for, is $125.
But then he notices he can get the print plus the web for the same price.
Now, that sounds like a deal! Or the marketer will put in a bigger, higher
priced model that he doesn’t expect to sell, to get someone to move up from
the economy model to the intermediate model, which he is hoping to sell. Here’s an example: 36-inch
Panasonic for $690 42-inch Toshiba
for $850 50-inch Philips
for $1,480 The customer may have been originally looking for
a 36-inch TV. But the overpriced huge
model makes the intermediate Toshiba look like a pretty good deal. (1-3) 2. The Fallacy of Supply and Demand The market isn’t always controlled by supply and
demand. It is controlled by images in
our minds. How much something is worth
to us is often “anchored” by the first price we see. We are “imprinted” by what we see
first. Once this price is fixed,
future prices seem high or low to us, not because of supply but by comparison
with the “anchor” price. First
impressions are important. “Starbucks did everything in its power … to make
the experience feel different—so different that we would not use the prices
at Dunkin’ Donuts as an anchor, but instead would be open to the new anchor
that Starbucks was preparing for us.” (39)
The first time we did it for a special treat. The second time it was easier to
justify. After that it became a habit
and we no longer questioned it. And
that’s how we moved up from spending $1.50 to $4.50 for coffee. So pay attention to first time decisions
and question your habits. (37-44) 3. The Cost of Zero Cost We often pay too much when we pay nothing. We get something we don’t really need, or
more than we need, in order to get something else we
don’t need for free. 4. The Cost of Social Norms Attorneys may not be willing to help the poor for
a reduced fee and yet they might be willing to donate their time for
free. It’s the difference between
responding to the market value and responding to a social obligation. (71)
Social and market norms have different rules. When you mix the two you get in trouble. Try offering your mother-in-law payment for
an excellent Thanksgiving dinner or mentioning the price of the restaurant
selections to your dinner date. Or, as
a corporation, appeal to your workers as part of “the family” to give a huge
effort to complete an important project and then lay off a bunch of people or
cut their insurance benefits when finances are tight. “You can’t treat your customers like family one
moment and then treat them impersonally…a moment later when this becomes more
convenient or profitable. This is not
how social relationships work. If you
want a social relationship, go for it, but remember that you have to maintain
it under all circumstances.” (79) 6. The Problem of Procrastination and Self-Control We are emotionally ‘cool’ when we make our
resolutions. But when we’re emotionally ‘hot,’ (tempted) we tend to go for
the immediate gratification. Without precommitments, we keep falling for temptation. 7. The High Price of Ownership We overvalue what we already have. Why does the asker ask an unreasonably high
price and the purchaser seek a much lower price? Why don’t we both value it the same? When we own something we tend to value it
more than other people do. We fall in
love with what we already have. We
focus more on loss than gain. Loss is
a strong emotion and we have an aversion to it. Once we have the higher speed internet or
the gold package or the 30-day trial, it is very difficult to give it up. We are everywhere tempted to improve the
quality of our lives with a larger house, a new dishwasher, a riding lawn
mower. But each time we move up, we
have a very hard time moving back to the previous state. Even thinking about the purchase tends to
move us toward the ownership mindset.
So try to look at each transaction as a non-owner. This is also true of ideas or points of view.
Once we take ownership of an idea, whether it is sports, politics, or
religion, we prize it perhaps more than it’s worth. And we have trouble letting go of it
because we can’t stand the loss. “What
are we left with then? An
ideology—rigid and unyielding.” (138) 8. Keeping Doors Open We have an
irrational compulsion to keep all our options open. But there is a cost. We sometimes fail to spend enough time on
what is really important. In our
society people aren’t faced with a lack of opportunity but a dizzying
abundance of it. Choosing between two
similarly attractive possibilities is one of our most difficult
decisions. Congress is frequently
deadlocked over the details of legislation both parties essentially
support. 9. The Effect of Expectations The mind gets
what it expects. Impressions made in our
minds, even subconsciously, affect what we experience. When we believe in advance that a food will
be tasty, or a medicine will be effective, we tend to experience what we
expect. We tend to react toward people
according to stereotypes in our minds.
And people tend to respond according to their stereotype if they are
aware of it. 10. The Power of Price We cannot avoid
thinking that a more expensive drug will be more effective than a cheaper
one. Placebos often yield at least
short term improvements in patient.
Price can change the experience.
We are likely to think that a discounted product is not as good or
effective as one at a normal or higher price.
It is amazing how our minds control our bodies. 11. The Context of Our Character, Part I Honest people
tend to cheat a little. In experiments,
the majority of people cheated just a little bit. However, when in some indirect way, the Ten
Commandments were brought to their consciousness before the experiment, they
didn’t cheat. “In other words, when we
are removed from any benchmarks of ethical thought, we tend to stray into
dishonesty. But if we are reminded of
morality at the moment we are tempted, then we are much more likely to be
honest.” (213) 12. The Context of Our Character, Part II People tend to
steal a little if it’s not actually cash. Many people make an insurance claim
for the loss of a 32-inch television set when it was really only a 27-inch
set. There seems to be a conscience
threshold below which the conscience isn’t triggered. “Even good people are
not immune to being partially blinded by their own minds.” (227) “We can be dishonest without thinking of
ourselves as dishonest. We can steal
while our conscience is apparently fast asleep.” (229) Companies do it
too. Try to redeem your airline miles
and you may find all the dates you want are “blacked out.” But if you are willing to spend twice as
many miles, the dates will become available.
Credit card companies find “trick” ways to charge you. 13. Beer and Free Lunches “We are all far
less rational in our decision making than standard economic theory
assumes. Our irrational behaviors are
neither random nor senseless—they are systematic and predictable. We all make the same types of mistakes over
and over, because of the basic wiring of our brains.” (239) |
