Survivor producer Mark Burnett paired with clinical psychologist Richard Levak to design a psychological screening program for "Survivor," and then most of the other reality TV shows too. That's where psychology got its toehold in reality TV. Through this, we get a really good sense for who they are. In my opinion, good 'Survivor' contestants have enough energy to be interesting and exciting on TVIt's not exciting to watch somebody who is fatigued and needs to lay down and rest the whole time. Being on any reality TV show is something you can't prepare for.
