Scaring Us Senseless
By NASSIM NICHOLAS TALEB
I WAS visiting London last Thursday when a second wave of attacks hit
the city, just two weeks after the traumatic events of July 7. It is
hard to avoid feeling vulnerable to this invisible enemy who does not
play by known or explicit rules. Of course, that is precisely the
anxiety that terrorists seek to produce. But its opposite -
complacency - is not an option.
The truth is that neither human beings nor modern societies are wired
to respond rationally to terrorism. Vigilance is easy to muster
immediately after an event, but it tends to wane quickly, as the
attack vanishes from public discourse. We err twice, first by
overreacting right after the disaster, while we are still in shock,
and later by under-reacting, when the memory fades and we become so
relaxed as to be vulnerable to further attacks.
Terrorism exploits three glitches in human nature, all related to the
management and perception of unusual events. The first and key among
these has been observed over the last two decades by neurobiologists
and behavioral scientists, who have debunked a great fallacy that has
marred Western thinking since Aristotle and most acutely since the
That is to say that as much as we think of ourselves as rational
animals, risk avoidance is not governed by reason, cognition or
intellect. Rather, it comes chiefly from our emotional system.
Patients with brain lesions that prevent them from registering
feelings even when their cognitive and analytical capacities are
intact are incapable of effectively getting out of harm's way. It is
largely our emotional toolkit, and not what is called "reason," that
governs our capacity for self-preservation.
Second, this emotional system can be an extremely naïve statistician,
because it was built for a primitive environment with simple dangers.
That might work for you the next time you run into a snake or a tiger.
But because the emotional system is impressionable and prefers
shallow, social and anecdotal information to abstract data, it hinders
our ability to cope with the more sophisticated risks that afflict
For example, the death of an acquaintance in a motorcycle accident
would be more likely to deter you from riding a motorcycle than would
a dispassionate, and undoubtedly far more representative, statistical
analysis of motorcycles' dangers. You might avoid Central Park on the
basis of a single comment at a cocktail party, rather than bothering
to read the freely available crime statistics that provide a more
realistic view of the odds that you will be victimized.
This primacy of the emotions can distort our decision-making.
Travelers at airports irrationally tend to agree to pay more for
terrorism insurance than they would for general insurance, which
includes terrorism coverage. No doubt the word "terrorism" can be
specific enough to evoke an emotional reaction, while the general
insurance offer wouldn't awaken the travelers' anxieties in the same
In the modern age, the news media have the power to amplify such
emotional distortions, particularly with their use of images that go
directly to the emotional brain.
Consider this: Osama bin Laden continued killing Americans and Western
Europeans in the aftermath of Sept. 11, though indirectly. How? A
large number of travelers chose to drive rather than fly, and this
caused a corresponding rise in casualties from automobile accidents
(any time we drive more than 20 miles, our risk of death exceeds that
Yet these automobile accidents were not news stories - they are a mere
number. We have pictures of those killed by bombs, not those killed on
the road. As Stalin supposedly said, "One death is a tragedy; a
million is a statistic."
Our emotional system responds to the concrete and proximate. Based on
anecdotal information, it reacts quickly to remote risks, then rapidly
forgets. And so the televised images from bombings in London cause the
people of Cleveland to be on heightened alert - but as soon as there
is a new tragedy, that vigilance is forgotten.
The third human flaw, related to the second, has to do with how we act
on our perceptions, and what sorts of behavior we choose to reward. We
are moved by sensational images of heroes who leap into action as
calamity unfolds before them. But the long, pedestrian slog of
prevention is thankless. That is because prevention is nameless and
abstract, while a hero's actions are grounded in an easy-to-understand
How can we act on our knowledge of these human flaws in order to make
our society safer?
The audiovisual media, with their ability to push the public's
emotional hot buttons, need to play a more responsible role. Of course
it is the news media's job to inform the public about the risk and the
incidence of terrorism, but they should try to do so without helping
terrorists achieve their objective, which is to terrify.
Television images, in all their vividness and specificity, have an
extraordinary power to do just that, and to persuade the viewer that a
distant risk is clear and present, while a pressing but underreported
one is nothing to worry about.
Like pharmaceutical companies, the news media should study the side
effects of their product, one of which is the distortion of the
viewer's mental risk map. Because of the way the brain is built,
images and striking narratives may well be necessary to get our
attention. But just as it takes a diamond to cut a diamond, the news
industry should find ways to use images and stories to bring us closer
to the statistical truth.
