“The great enemy of communication…is the illusion of it.” –William H. Whyte
What if 9 out of every 10 Americans had trouble understanding and responding to ordinary traffic signs? It would be a national emergency, of course. Imagine the chaos, the crashes, and the loss of life that would occur if people didn’t know how to interpret stop signs, one way signs, do not enter signs, speed limits, and sharp curve ahead warnings. The public’s health and safety would be in grave danger and immediate action would be required.
