Have you ever wondered how to define talent? In ancient times the word talent was referred to as a measure of silver that was paid in exchange of someone's work. Better output by the person resulted in more payment - hence more "talent".We get fooled because we believe since we spend a lot of time with human beings we must be good at evaluating their talent and potential. There is a science of human behavior and a science to talent, just like there is science to astrophysics.
