Hotel towel re-use

Noah Goldstein, UCLA assistant professor of HR and organised behaviour, headed up a 2010 study on how to encourage towel reuse among hotel guests. In one experiment, two different signs were tested in rooms.:

• 1st sign had an appeal saying that towel reuse is good for the environment; 35% of guest complied.
• 2nd sign added a social cue: "Almost 75% of guests who are asked to participate... do help by using their towel more than once." 44% compliance.
