Conscientiousness is a personality trait that is associated with the Big Five personality model. It is characterized by exceptional organizational skills, cautiousness, neatness, rigidness, detail-orientedness, and scrupulosity. People who score high on conscientiousness tend to be neat, prudent, and organized in their daily lives and are less likely to engage in risky behaviors which may jeopardize their ultimate fruition and wellbeing. People who score higher on this trait are admittedly susceptible to developing OCD or OCPD. However, studies demonstrate the positive role that conscientiousness may play on maximizing happiness throughout one's life.
