There are people who regularly complain of being unlucky; more rare are the individuals who assert that they are lucky. This conviction about good luck and bad luck occurs in people who are not otherwise superstitious. Feldman concludes that this belief in luck, good or bad, is a compromise achieved by the ego in its attempt to reconcile demands from the id for gratification of aggressive and sexual drives opposed by prohibitions and restrictions from the superego. The chronic complainer in effect is denying the excessive infantile demands he makes upon the world.
