Social Psychology: The Decisive Impact Of Being Given A Map

"Here is a famous finding from social psychology. If you want to encourage people to get vaccinated against some disease, it helps to educate them about the benefits of vaccination. But you'll have a much bigger impact if you give people a map, showing them exactly where to go to get a shot. Elementary though it is, this finding is important, because it demonstrates that when people don't respond to a suggestion, it may be because they need some help in identifying the specific steps they are being asked to take. People pay a lot more attention if they are given something like a map." Cass R. Sunstein in Bloomberg
