Turbulent types are higher in neuroticism and perceive dangers more often. This leads them to have higher levels of stress and anxiety which leads to self-doubt and uncertainty.
The Assertive subtype relates to lower neuroticism and higher emotional stability. As a result, they tend to be calm and collected even in stressful situations. They are more self-assured, confident, and assertive.

This logical approach helps them arrive at objective conclusions swiftly.
