If the idea of throwing caution to the wind makes you break
out in a cold sweat, you’re not alone. Taking risks is hard
because we detest losses—so much so that we’ll go to irrational
lengths to avoid them.
Loss aversion is the idea that losses loom larger than
gains. We’re more upset by the loss of $100 than we are
happy to win that same amount. Princeton psychologist
Daniel Kahneman and Stanford psychologist Amos Tversky
determined that, when it comes to money, fear is actually
2.5 times stronger than greed or reward. Their study of
how people manage risk and uncertainty won Kahneman
the Nobel Prize in Economics in 2002, seven years after
Tversky’s death.
“Fear usually dominates greed,” says Dr. Richard
Peterson, a psychiatrist and Stanford trained neuroeconomics
expert. “It’s an adaptive trait. Our ancestors wouldn’t
have lived long if they saw the grass rustling and they didn’t
assume it was a lion and run away.” Loss aversion drives our
red light. It makes us hold onto loser stocks when we should
sell, it drives us to throw good money after bad, and it compels
us to continue paying for gym memberships that we
never use.
The part of the brain that is most responsible for loss
aversion appears to be the amygdala, which stores fearful
memories. The role of the amygdala can be seen in a research
study, in which people with a damaged amygdala, as well as
those with an intact brain, were asked to make a series of
bets. In each one, the subjects could choose to invest a dollar
or abstain.
Study participants with intact brains invested 60 percent
of the time. When they lost money in a round, they didn’t
invest in the next round. But people with damaged amygdalas
kept on investing after a loss. They realized that the best
way to recoup the loss was to stay in the game. They invested
83.7 percent of the time and had significantly better results
than those with intact brains.
