Authority Bias

In one experiment, participants were stopped in the street by a civilian or a guard and asked to pick up a bag, give a dime to a stranger, or move away from the bus stop. 

The result?

While 83% obeyed the guardonly 46% obeyed the civilian. 

People are more likely to unconsciously follow the direction of those who are in a position of authority.
