I GREW UP terrified, my childhood catechized by the violence in Northern Ireland, each week a litany of murder. I grew used to the idea that killing was the story of our lives. This, of course, was not true—there was also beauty and friendship all around us, all the time, not to mention eventually a peace process that has delivered extraordinary cooperation between former sworn enemies.
But the way we learned to tell the story—from political and cultural leaders, religion, and the media—emphasized the darkness. It’s been a long and still ongoing journey for me to discern how to honor real suffering while overcoming the lie that things are getting worse.
Today, many of us are living with a fear that seems hard to shake. Horrifying, brutal videos, edited for maximum sinister impact, showing up in our newsfeeds are only the most recent example of how terror seems to blend into our everyday lives.
But things are not as bad as we think. What social scientists call the “availability heuristic” helps explain why we humans find it difficult to accurately predict probability. In short, we guess the likelihood of something happening based on how easily we can recall examples of something similar having happened before. Because of this, folk who get a lot of “information” from mainstream media may tend to overestimate the murder rate: Most of us have seen vastly more killing on TV than would ever compute to an accurate estimate of real-world rates of killing.
Globalization and cyberspace bring more images and stories than our brains can handle, blending them with our lives to the extent that we consciously have to work to create boundaries between our screens and our psyches. One consequence is that people are skeptical when told that violence has been declining over time, and we are living in what is probably the most peaceful era human beings have ever known. But it’s true.
