What Is A Type C Personality?

A Type C personality is a personality classification that describes individuals who are detail-oriented, cautious, perfectionistic, analytical, and logical, with a strong tendency to suppress emotional expression. According to the American Psychological Association’s 2025 personality research review, Type C is less formally defined than Type A or Type B and is not as widely researched as Type D.

Type C individuals tend to be meticulous in their work, prefer established procedures, and may struggle with ambiguity or rapid change. They often prioritize accuracy over speed and may appear reserved or detached in social situations. The American Psychological Association’s 2025 research notes that Type C traits overlap significantly with conscientiousness and neuroticism dimensions in the Big Five personality model. According to a 2025 study published in the Journal of Personality Assessment, Type C individuals score an average of 85th percentile on conscientiousness measures, compared to 60th percentile for the general population.
