Self-esteem: we all have the same amount

Despite what you might think about how a person's personality type effects his or her self-confidence, recent research proves that everyone has the same self-esteem.

Psychologists used to think that outward expressions -- like a self-effacing person who can't seem to take a compliment -- were indicators of a person's self-worth, but now they try and measure "implicit self-esteem."

To do that, psychologists use an Implicit Association Test -- an exam in which researchers would give study participants a series of pleasant words, and as them to use those words in self-referential statements ("Good" would become "I am good," etc).

The tests showed that -- while there were superficial cultural differences, like Americans who were more likely to boast about themselves than, say, someone from China -- all participants had the same amount of implicit self-esteem.

It's just that with some people, their confidence is hiding beneath the surface.
