Which Big Five trait is most strongly associated with overall job performance?

• A. Openness
• B. Conscientiousness
• C. Neuroticism
• D. Extraversion

Answer: (B)

Conscientiousness stands out because it captures reliability, organization, persistence, and a focus on goals—qualities that directly drive consistent, high-quality work. People high in this trait tend to plan effectively, meet deadlines, pay attention to detail, and stay persistent in the face of obstacles, which translates into superior overall job performance across a wide range of roles. Other Big Five traits can influence performance in specific contexts (for example, extraversion in social or sales tasks, openness in creative work), but they don’t predict general performance as reliably as conscientiousness. Neuroticism, in contrast, often undermines performance due to stress and emotional instability.
