People often imitate those around them. They dress in the same styles as their friends, pick entrées preferred by other diners, and reuse hotel towels more when they think others are doing the same. People are more likely to vote if their spouse votes, more likely to quit smoking if their friends quit, and more likely to get fat if their friends become obese. Whether making trivial choices like what brand of coffee to buy or important decisions like paying their taxes, people tend to conform to what others are doing.
