Nerds are often discriminated against and bullied. While some say it is due to their glasses or intelligence, the real reason is that nerdy behavior undermines social norms by being obsessive, socially inept, and lacking common sense. A nerd describes himself as someone who is smart, wears glasses, likes math, and plays in the school band. However, he questions why these interests make him uncool or cause him to be picked on. He wonders why intelligence is looked down upon. A nerd interviewed says the stereotypes about nerds being stupid, irritating or unattractive are false and ignorant. The only real commonality among nerds is their intelligence.
