Elena conducted a field experiment to investigate obedience to authority. She wanted to see if passersby would pick up a dropped piece of litter when instructed to do so by a confederate. The confederate was dressed either in a security guard's uniform (high authority condition) or in everyday casual clothes (low authority condition).
