5. Anchoring and adjustment bias—being influenced by an initial figure. It is sometimes seen in
real-estate sales. Before the crash in the real-estate markets, many homeowners might have been
inclined at first to list their houses at an extremely high (but perhaps randomly chosen) selling
price. These sellers were then unwilling later to come down substantially to match offers that
reflected what the marketplace thought the house was really worth.
The potential home buyers may make a reasonable offer for a house, but the owners may be
unwilling to negotiate because they became fixated on their initial figure (asking price), which was
too high.
6. The overconfidence bias—people’s subjective confidence in their decision making is greater
than their objective accuracy. For instance, with experienced investment advisors whose financial
outcomes simply depended on luck, “the illusion of skill is not only an individual aberration; it is
deeply ingrained in the culture of the industry.”
The young couple may believe that they should buy a house in a certain town because “the town is
on its way up, and we’ll be able to make a boatload of money by selling our house a few years from
now.”
7. The hindsight bias—the tendency of people to view events as being more predictable than they
really are, as when at the end of watching a game we decide the outcome was obvious and
predictable, even though in fact it was not.
After the home buyers purchase a house, they may look back and say, “From the first minute we
walked in the door, we knew that we’d be living here within a month.”
8. The framing bias—shaping how a problem is presented. The framing bias is the tendency of
decision-makers to be influenced by the way a situation or problem is presented to them. For
instance, customers have been found to prefer meat that is framed as “85% lean meat” instead of
“15% fat,” although, of course, they are the same thing.
The potential home buyers may be influenced by a realtor describing a house as “the ideal house
for people who have many friends and love to entertain.” If the potential home buyers see
themselves as popular, they may be more likely to buy the house because of the way the real-estate
agent framed it.
9. Escalation of commitment bias—increasing commitment to a project despite negative feedback
about it. A website called Swoopo.com capitalizes on this bias by offering a penny auction in
which, say, a $1,500 laptop is offered for bidding starting at a penny and going up one cent at a
time, but it costs bidders 60 cents to make a bid. “Once people are trapped into playing,” suggests
one account about this form of bias, “they have a hard time stopping.”
If the home buyers decide to buy a house, they may bring their parents to see it. The parents may
point out various defects in the house, which only makes the home buyers more insistent on buying
the house because their commitment to buying the house has escalated.
