Conscientiousness is crucial in business for several reasons. First, it is linked to higher job performance. Employees who score high on conscientiousness are more likely to be productive, meet deadlines, and maintain a high level of quality in their work. Second, it contributes to employee reliability. Conscientious individuals are less likely to engage in counterproductive work behaviors, such as tardiness or absenteeism, and are more likely to adhere to company policies and ethical standards.
