Authority
People tend to obey authority figures or those perceived as experts in their field.
Why it works
Based on Milgram's obedience studies (1963) and evolutionary psychology, humans evolved deference to authority as a survival mechanism. Authority reduces cognitive load by providing trusted decision shortcuts, while expertise signals competence that people want to associate with. This creates powerful influence even when authority is merely implied (Cialdini, 2007).
