“One afternoon, Reeves and a colleague were having lunch in Central Park. On the way back to their Madison Avenue office, they encountered a man sitting in the park, begging for money. He had a cup for donations and beside it was a sign, handwritten on cardboard, that read: I AM BLIND. Unfortunately for the man, the cup contained only a few coins. His attempts to move others to donate money were coming up short. Reeves thought he knew why. He told his colleague something to the effect of: “I bet I can dramatically increase the amount of money that guy is raising simply by adding four words to his sign.” Reeves’s skeptical friend took him up on the wager. Reeves then introduced himself to the beleaguered man, explained that he knew something about advertising, and offered to change the sign ever so slightly to increase donations. The man agreed. Reeves took a marker and added his four words, and he and his friend stepped back to watch. Almost immediately, a few people dropped coins into the man’s cup. Other people soon stopped, talked to the man, and plucked dollar bills from their wallets. Before long, the cup was running over with cash, and the once sad-looking blind man, feeling his bounty, beamed. What four words did Reeves add? It is springtime and The sign now read: It is springtime and I am blind. Reeves won his bet. And we learned a lesson. Clarity depends on contrast.”
