House accurately deduces people's motives and histories from aspects of their personality, appearance, and behavior. His friend and colleague Wilson says that while some doctors have the "Messiah complex" (they need to "save the world"), House has the "Rubik's complex" (he needs to "solve the puzzle"). House typically waits as long as possible before meeting his patients. When he does, he shows an unorthodox bedside manner and uses unconventional treatments. However, he impresses them with rapid and accurate diagnoses after seemingly not paying attention.
