People who tend to think and behave in the same way are said to have the same personality. When the personalities of lucky and unlucky people are compared on the five dimensions of personality – agreeableness, conscientiousness, extroversion, neuroticism and openness – lucky and unlucky people had only agreeableness (the degree to which someone is sympathetic toward others) and conscientiousness (the degree to which a person is self-disciplined, strong-willed and determined) in common.
