Fear Is Unhealthy
The New York Times writes about a plausible connection between fear and heart disease:
Which is more of a threat to your health: Al Qaeda or the Department of Homeland Security?
An intriguing new study suggests the answer is not so clear-cut. Although it’s impossible to calculate the pain that terrorist attacks inflict on victims and society, when statisticians look at cold numbers, they have variously estimated the chances of the average person dying in America at the hands of international terrorists to be comparable to the risk of dying from eating peanuts, being struck by an asteroid or drowning in a toilet.
But worrying about terrorism could be taking a toll on the hearts of millions of Americans. The evidence, published last week in the Archives of General Psychiatry, comes from researchers who began tracking the health of a representative sample of more than 2,700 Americans before September 2001. After the attacks of Sept. 11, the scientists monitored people’s fears of terrorism over the next several years and found that the most fearful people were three to five times more likely than the rest to receive diagnoses of new cardiovascular ailments.
After controlling for various factors (age, obesity, smoking, other ailments and stressful life events), the researchers found that the people who were acutely stressed after the 9/11 attacks and continued to worry about terrorism—about 6 percent of the sample—were at least three times more likely than the others in the study to be given diagnoses of new heart problems.
If you extrapolate that percentage to the adult population of America, it works out to more than 10 million people. No one knows what fraction of them might consequently die of a stroke or heart attack—plenty of other factors affect heart disease—but if it were merely 0.0003 percent, that would be higher than the 9/11 death toll.
Of course, statistics of any sort, even when the numbers are rock solid, don’t mean much to people when they’re assessing threats. Risk researchers have found that even when people know the numbers, they’re less worried about death tolls than about how the deaths occur. They have good reasons—called “rival rationalities”?—for fearing catastrophes that kill large numbers at once because these events affect the whole community and damage the social fabric.
It doesn’t surprise me that fear of terrorism is more harmful than actual terrorism. That’s the whole point of terrorism: an amplification of fear through the mass media.
The point of terrorism is to cause terror, sometimes to further a political goal and sometimes out of sheer hatred. The people terrorists kill are not the targets; they are collateral damage. And blowing up planes, trains, markets or buses is not the goal; those are just tactics. The real targets of terrorism are the rest of us: the billions of us who are not killed but are terrorized because of the killing. The real point of terrorism is not the act itself, but our reaction to the act.
And we’re doing exactly what the terrorists want.
The surest defense against terrorism is to refuse to be terrorized. Our job is to recognize that terrorism is just one of the risks we face, and not a particularly common one at that. And our job is to fight those politicians who use fear as an excuse to take away our liberties and promote security theater that wastes money and doesn’t make us any safer.
