For example, in the United States, the violent-crime rate has been on a downward trend since 1990. Just under 14.5 million crimes were reported in 1990. By 2016 that figure was well under 9.5 million. Each time something horrific or shocking happened, which was pretty much every year, a crisis was reported. The majority of people, the vast majority of the time, believe that violent crime is getting worse. No wonder we get an illusion of constant deterioration.
