We find there is much uncertainty in selecting talent. If superstars are found, they are usually identified early. However, more false positives exist than correct decisions with high draft picks. Our results suggest the dilemma of choosing talent is not so much a winner’s curse but more like a purchase of a lottery ticket. Most times you lose, but, if you are going to win, you must buy a ticket. I. Introduction movie studios pursue the next Titanic and music producers seek the next Beatles.
