How to find out what people really think.
If you ask somewhat what they do, think or believe there's a very good chance you won't get the truth.
What you'll get is what they want you to believe about them, or what they want to believe about themselves.
For example, if you ask: "Are you always honest?" or "Are you a courteous driver?" they're probably going to tell you "yes" even if that isn't really true.
A better way to find out what people do, think or believe is to ask them what they think most other people do, think or believe, according to economist Tyler Cowen.
"I think most people are usually honest but will lie when it's convenient" or "most people are a**holes behind the wheel" probably reveals the truth about that person more than it demonstrates the ability of that person to gauge statistical probabilities about the general population.
The reason is that people both have inaccurate views about themselves and also believe their actions and thoughts and beliefs are representative of the majority of people. http://psychcentral.com/blog/archives/2013/05/24/want-to-know-what-someone-really-thinks/(The picture is unrelated: It shows part of a statue at Valencia's Las Fallas festival.)
