Heading to a conference this fall at staying in a hotel? Will you have the towels replaced after every shower? An interesting 60 second podcast from Scientific America explains a study done on the marketing message left about replacing your towel. When “Join Your Fellow Guests in Helping to Save the Environment” card messages were left, rather than just “Help Save the Environment” more hotel guests choose NOT to have their towels replaced. Why? Though 3/4 of Americas say they are environmentalist, most are swayed more often by the majority. Think about this example when you are marketing for your library. Perhaps a message to your patrons “join your fellow patrons by….” would increase the likelihood of participation in a green initiative or program.
