You are interested in investing in land or shares
or anyother ? Reason to be careful.
You buy a risky investment impulsively. You beat yourself
up over an investment that's losing money, but you
can't bear to sell it. For most investors, these types
of irrational, shortsighted decisions are normal and
automatic But with the help of a new branch of science,
neuro-economics, investors can learn how to resist
their self-destructive tendencies.
Neuro-economics shows that our brains are wired with
two different systems, each struggling for control
of our financial decisions. The prefrontal cortex
brain (cortex) is highly evolved and rational. The
limbic system (limbic), is more primitive and reactive.
All too often limbic takes control, even when it's
not in our interest.
Experiments reveal that limbic can be striking. Researchers
at Stanford had students play a simple game in which
they could win or lose money depending on how quickly
they pushed a button. During the game, an MRI machine
scanned the students' brains. Scientists discovered
that the thought of making money pushed the reward
system of the students' brains into high gear. That
system releases dopamine, the pleasure chemical of
the brain. The bigger the perceived reward, the more
dopamine. The more dopamine, the more emotions control
your decisions.
Sexy but dangerous
Although the experiment didn't focus on investing
decisions, you can draw some conclusions. If you're
thinking of how sexy an investment is or how fast
its price is rising, but not thinking about how it
compares with other investments, means if you're acting
on the basis of excitement, you'll make bad decisions.
Moreover, when we see opportunities for big rewards,
we tend to downplay the potential risks. The part
of the brain that kicks in during the presence of
high-reward opportunities responds to how much you
think you can make, but not probability. It's like
you are drunk and are going after the hottest woman
at a party.
The two systems also come into force when you must
choose between long-term and short-term gratification.
Put simply, the emotional system is impulsive and
myopic. Brain scans show that the promise of an immediate
reward set off an emotional response, limbic wants
things now.
But when given a choice between rewards of varying
amounts at different times in the future cortex prevailed.
For example, offered a choice between a $5 gift certificate
in two weeks or a $40 one in six weeks, most participants
in the above mentioned experiment delayed gratification
for the larger reward down the road. Our emotional
brain wants fun now, our logical brain knows we should
save for retirement and go for health.
Our emotional brain – limbic - is incapable
of thinking about the future. Neuro scientific research
discovered that Vietnam veterans with injuries to
cortex struggled when making long-term financial decisions.
They had a difficult time articulating goals for the
future, especially far into it, such as planning for
retirement or saving for their children's education.
Another component of our neural wiring that hamstrings
financial decision-making is that we are programmed
to see patterns. At a very deep level, it's what our
brains do. This ability is useful in the natural world,
where there is often good reason to assume a pattern
is meaningful. In the days when humans were hunter-gatherers
a man who found three nests that contained eggs would
check a fourth nest.
Nowadays, though, that kind of assumption could cause
problems. For example, you see red come up three straight
times on a roulette wheel. What do you do? Bet next
month's mortgage payment on red?
In investing, the pattern we see is often a coincidence.
But the subconscious part of our brain urges us to
act on this pattern. It may override the rational
part, which may see, for instance, that your targeted
investment has become wildly overpriced.
The broken pattern
Now what do you do if you reach into that fourth nest
and a snake bites you? You'll almost certainly start
giving nests a wide berth. When a pattern is broken,
your brain generates feelings of fear and revulsion
-- which is a good thing because it lessens the likelihood
of future snake bites. But that is not necessarily
a desirable outcome for investors. If a company releases
a poor earnings report, you may sell the stock even
if it is still a sensible investment, or you may be
so disgusted that you do nothing when, in fact, you
should sell the stock.
Because our minds are wired to avoid the unpleasant.
Bad memories last much longer than good ones as positive
stimulations are short-lived. Those mechanisms turn
on and off quickly. But if you're scared by a saber-toothed
tiger, you'll be scanning the bushes for the next
three years.
Trusting patterns is one thing. But what about trusting
people? Science has something to say on that subject,
too. The trust game has become a staple of neuro-economic
research. Variations exist, but basically the game
involves a trustee and an investor. The investor sends
the trustee money and the rules of the game say that
that mere act automatically expands the amount of
cash. The trustee may then share the wealth with the
investor and return some of the money or -- and here's
the rub -- the trustee may burn the investor and send
back nothing.
You might think that behavior in such a game would
be based on a simple financial calculation: I'll send
more money if I get more back. But trust is an emotional
response. The hormone oxytocin fills different areas
of the brain in social situations, such as bonding
between spouses or between parents and children. We
are a social species, and it's a good thing that we
can learn how to trust. As a certain amount of cooperation
between parties benefits both of them. Just how powerful
is oxytocin? In a version of the trust game researchers
discovered that simply squirting a dose of oxytocin
up a test subject's nose prompted the person to give
the trustee more money.
What’s the solution?
Although neuro-economics identifies the reasons for
our actions, it's less helpful in prescribing corrective
measures. But that doesn't mean you have to wait a
few hundred thousand more years for your brain to
evolve to the point that you can approach your finances
more rationally.
The overarching rule is that investors must learn
to recognize situations that will set off emotional
decisions. Then you can place yourself in a circumstance
that doesn't require you to make snap decisions. When
it comes to trust, for example, you shouldn't act
on someone's financial advice just because you like
the person.
If you are presented with a high-reward opportunity
-- say, a broker calls with a hot tip on a penny stock
-- wait. Acting on impulse means you won't properly
weigh the risks involved. Let your rational brain
part spend some time researching the investment --
no sense in having a highly evolved brain if you don't
use it. And be aware of patterns. Sometimes they're
valid, sometimes they're not. Get the big picture
about your possible investment before investing.
Follow these other simple rules, and you stand a much
better chance of moving the investment decision-making
process into the rational part of your brain:
Don't fixate on the short term. A daily, or even hourly,
diet of news fires up your emotional brain part and
can trigger fear and greed, two emotions that often
trip up investors. In the same vein, don't check the
prices of your investments too often.
Set long-term goals for your investments. Research
has shown that as soon as you stop thinking short
term and start thinking about the long term, the emotional
part of your brain shuts off.
Diversify and examine the performance of your portfolio
as a whole. Big rewards and big losses set off emotional
responses. A diversified portfolio evens out these
ups and downs.
Set a timetable for when to sell stocks and other
investments. That sell discipline creates rational
goals and preempts emotional reactions.
That’s it for this one.
