"About one in ten people are me. The world was not designed for me. For centuries I was considered unlucky or even evil. But some of history's greatest minds were me. What am I?"

Answer: Left-handed. About 10% of the population is left-handed. Most tools, instruments, and layouts are designed for right-handers. In many historical cultures left-handedness was considered sinister (the word sinister means left in Latin). Yet many brilliant people including Leonardo da Vinci and Einstein were left-handed.
