What would you think if you were walking or driving down the street and you saw a sign that said, “Honk Less, Love More” or “Follow Dreams, Not Crowds” or “Have a Great Day?” Would these signs make you happier, or at least more inclined to behave decently? Might they help lower crime? Would they boost morale? British artist Killy Kilford seems to think so, and he’s testing his theory in one of American’s most crime-ridden cities: Newark, New Jersey. According to an article in New York magazine, Kilford is planning on placing hundreds of signs like this throughout the city and has “zero doubt” that the signs will make a positive impact on city.

I thought about this idea on the way to work. I imagined seeing a sign on the side of the road telling me to follow my dreams or to smile or to have a great day. Initially, I was very cynical—I thought that signs like this would more likely than not simply annoy rather than inspire me. I have a very low platitude-tolerance threshold at the best of times, and the idea that some government department somewhere was trying to alter my behavior or dispositions with a bunch of formulaic roadside wellness exhortations could just be enough to send me over the edge.

But then I began to think about signs more metaphorically. Specifically, I began to think about the practice of holding up ideals before people as an attempt to influence and/or change their behavior or beliefs. And of course it didn’t take too much thinking along these lines to be reminded that this is pretty much exactly what I do for a living.
