Our New found Fear of Risk

We're afraid of risk. It's a normal part of life, but we're increasingly unwilling to accept it at any level. So we turn to technology to protect us. The problem is that technological security measures aren't free. They cost money, of course, but they cost other things as well. They often don't provide the security they advertise, and -- paradoxically -- they often increase risk somewhere else. This problem is particularly stark when the risk involves another person: crime, terrorism, and so on. While technology has made us much safer against natural risks like accidents and disease, it works less well against man-made risks.
Three examples:

  1. We have allowed the police to turn themselves into a paramilitary organization. They deploy SWAT teams multiple times a day, almost always in nondangerous situations. They tase people at minimal provocation, often when it's not warranted. Unprovoked shootings are on the rise. One result of these measures is that honest mistakes -- a wrong address on a warrant, a misunderstanding -- result in the terrorizing of innocent people, and more death in what were once nonviolent confrontations with police.
  2. We accept zero-tolerance policies in schools. This results in ridiculous situations, where young children are suspended for pointing gun-shaped fingers at other students or drawing pictures of guns with crayons, and high-school students are disciplined for giving each other over-the-counter pain relievers. The cost of these policies is enormous, both in dollars to implement and its long-lasting effects on students.

  3. We have spent over one trillion dollars and thousands of lives fighting terrorism in the past decade -- including the wars in Iraq and Afghanistan -- money that could have been better used in all sorts of ways. We now know that the NSA has turned into a massive domestic surveillance organization, and that its data is also used by other government organizations, which then lie about it. Our foreign policy has changed for the worse: we spy on everyone, we trample human rights abroad, our drones kill indiscriminately, and our diplomatic outposts have either closed down or become fortresses. In the months after 9/11, so many people chose to drive instead of fly that the resulting deaths dwarfed the deaths from the terrorist attack itself, because cars are much more dangerous than airplanes.
There are lots more examples, but the general point is that we tend to fixate on a particular risk and then do everything we can to mitigate it, including giving up our freedoms and liberties.
There's a subtle psychological explanation. Risk tolerance is both cultural and dependent on the environment around us. As we have advanced technologically as a society, we have reduced many of the risks that have been with us for millennia. Fatal childhood diseases are things of the past, many adult diseases are curable, accidents are rarer and more survivable, buildings collapse less often, death by violence has declined considerably, and so on. All over the world -- among the wealthier of us who live in peaceful Western countries -- our lives have become safer.
Our notions of risk are not absolute; they're based more on how far they are from whatever we think of as "normal." So as our perception of what is normal gets safer, the remaining risks stand out more. When your population is dying of the plague, protecting yourself from the occasional thief or murderer is a luxury. When everyone is healthy, it becomes a necessity.
Some of this fear results from imperfect risk perception. We're bad at accurately assessing risk; we tend to exaggerate spectacular, strange, and rare events, and downplay ordinary, familiar, and common ones. This leads us to believe that violence against police, school shootings, and terrorist attacks are more common and more deadly than they actually are -- and that the costs, dangers, and risks of a militarized police, a school system without flexibility, and a surveillance state without privacy are less than they really are.
Some of this fear stems from the fact that we put people in charge of just one aspect of the risk equation. No one wants to be the senior officer who didn't approve the SWAT team for the one subpoena delivery that resulted in an officer being shot. No one wants to be the school principal who didn't discipline -- no matter how benign the infraction -- the one student who became a shooter. No one wants to be the president who rolled back counterterrorism measures, just in time to have a plot succeed. Those in charge will be naturally risk averse, since they personally shoulder so much of the burden.
We also expect that science and technology should be able to mitigate these risks, as they mitigate so many others. There's a fundamental problem at the intersection of these security measures with science and technology; it has to do with the types of risk they're arrayed against. Most of the risks we face in life are against nature: disease, accident, weather, random chance. As our science has improved -- medicine is the big one, but other sciences as well -- we become better at mitigating and recovering from those sorts of risks.
Security measures combat a very different sort of risk: a risk stemming from another person. People are intelligent, and they can adapt to new security measures in ways nature cannot. An earthquake isn't able to figure out how to topple structures constructed under some new and safer building code, and an automobile won't invent a new form of accident that undermines medical advances that have made existing accidents more survivable. But a terrorist will change his tactics and targets in response to new security measures. An otherwise innocent person will change his behavior in response to a police force that compels compliance at the threat of a Taser. We will all change, living in a surveillance state.
When you implement measures to mitigate the effects of the random risks of the world, you're safer as a result. When you implement measures to reduce the risks from your fellow human beings, the human beings adapt and you get less risk reduction than you'd expect -- and you also get more side effects, because we all adapt.
We need to relearn how to recognize the trade-offs that come from risk management, especially risk from our fellow human beings. We need to relearn how to accept risk, and even embrace it, as essential to human progress and our free society. The more we expect technology to protect us from people in the same way it protects us from nature, the more we will sacrifice the very values of our society in futile attempts to achieve this security.
