This question about behavior is from Dan Ariely’s “Irrational Game.”
Scenario
A hotel was trying to figure out the best way to encourage guests toward one behavior – to reuse their towels.
They showed the first group of guests a message emphasizing the importance of caring for the environment.
They showed the second group a message emphasizing that 75% of their guests had already participated in this program. Therefore, they should join their fellow guests by helping them save the environment.
44.1% of the guests in the second group reused their towels.
Question
What percentage of the guests in the first group reused their towels?
- Only 10% as many as the second group.
- About 75% as many as the second group.
- The percentage was the same for both groups.
- About 50% more than the second group.
