Conscientiousness is the personality trait of being thorough, careful, or vigilant. Conscientiousness implies a desire to do a task well. Conscientious people are efficient and organized as opposed to easy-going and disorderly. They exhibit a tendency to show self-discipline, act dutifully, and aim for achievement; they display planned rather than spontaneous behavior; and they are generally organized and dependable. It is manifested in characteristic behaviors such as being neat and systematic; also including such elements as carefulness, thoroughness, and deliberation (the tendency to think carefully before acting.) Conscientiousness is one of the five traits of the Five Factor Model of personality and is an aspect of what has traditionally been referred to as having character. Conscientious individuals are generally hard-working and reliable. They are also likely to be conformists. When taken to an extreme, they may also be "workaholics", perfectionists, and compulsive in their behavior. People who score low on conscientiousness tend to be laid back, less goal-oriented, and less driven by success; they also are more likely to engage in antisocial and criminal behavior.
