One key to holding on to our sanity is realizing that it is in the interest of so many others to keep us in a state of fear. Fearful people stay riveted to news programs, they buy lots of stuff they don't need, they indulge in expensive and unhealthful habits to dull the pain, they give up their vital freedoms and basic rights in the name of security, and their anxiety is all too easily turned to anger and hatred. Fearful people are sheep, easily manipulated and ready prey for the politician, the salesman, the agitator, the televangelist, the gang leader.
Another key is to understand that as horrific as are the events we hear about on the news, they are much more rare than we are led to believe by those who profit from our fears. From school shootings to vaccine reactions, from raw cookie dough illnesses to child kidnappings by strangers, we are given the impression that statistically infinitesimal risks are looming over us daily. They're not.
Generally, crime rates in America are much lower now than they were when my own children were young, but it's today's parents who are afraid to let their kids walk to school—or even play in the back yard without an adult present—and won't leave 11-year-olds alone at home for a few hours. (Twenty years ago, 11-year-olds were considered responsible babysitters.) When one is bombarded daily, and repeatedly, with stories of crime, and crimes against humanity, it's hard not to think that our world is worse than it is. More concerning still, studies show that fictitious violence (movies, television, video games) has the same effect on our gut as real news stories.
In any case, here's the very important paradox: No matter how bad we may think the world is, the way to raise healthy, well-adjusted children—the kind who will contribute to making the world better—is to avoid passing on our anxieties. Children need to know that the world is, generally, a safe place, beginning with their own families, and that where it is not, it can be faced with courage and hope. Growing up fearful is not conducive to good mental health.
How to resolve this? For one thing, we should help our children to become as competent as possible in basic life skills, so that they have—and know that they have—the tools to face the world as it comes to them. I also recommend the Fred Rogers quote about the importance of looking to the helpers in any bad situation. And stories. Lots of good stories, from biographies of heroes to heroic fairy tales, where evil is defeated by goodness and strength and courage. As C. S. Lewis said, "Since it is so likely that they will meet cruel enemies, let them at least have heard of brave knights and heroic courage."
Maybe that can work for adults as well. It's worth a try.
