Yes, the test usually identifies a combination of 2–3 types. Accentuations are rarely found in a "pure" form. For instance, a combination of emotive and exalted types is common among creative individuals.
Each accentuation has its strengths. Demonstrative types succeed in public-facing roles, stuck (persistent) types in sciences and law, and hyperthymic types in business. The test helps find an environment where your traits become an advantage.
Yes, different types react to stress differently. The anxious type is more prone to sleep disorders, the excitable type to cardiovascular issues due to anger outbursts, and the emotive type to physical discomfort from deep empathy.
While character core is stable, answers are influenced by current stress, life crises, or therapy. Over time, individuals develop compensation mechanisms, and traits that were once sharp may become smoother.
Statistically, emotive and exalted types are more frequent in women, while excitable and stuck types are more common in men. However, these are general trends, and the test primarily evaluates individuality.
