What is naive realism?
Bias that assumes our actions are correct 
False consensus: overestimate how many people share your opinion or how many people do the bad things you do

Who investigated naïve realism?
Ross et al (1977) 
P's asked to wear sandwich board and humiliating costume 
Asked what they thought of the others if they agreed and vice versa
People who agreed said the others were scared of embarrassment and weak 
People who refused said people who agreed were show-offs 
Whatever you choose is the right choice
