Developed by psychology researchers. Tests different dimensions of personality, and has breakdowns for character types.
You can find the character type descriptions here:
Your S-score was below 20 (very low). This is consistent with a dominant character type.
The S-score is a measure of anxiety, depression or submissiveness in social relations on a scale of 0-100. If the score is >20-30, then it becomes likely that either trait N or A, or both, is only partially expressed. This test does not explore the many possible reasons for a high S-score. The most common reason is suppressed aggression (submissive types) or suppressed narcissism (narcissistic borderline types). In individuals having consulted a mental health professional common reasons might be depression or bipolar disorder. The T-score is a measure of temperament, also on a scale of 0-100. Low temperament individuals tend to be reserved or phlegmatic. High temperament individuals tend to be reactive or volatile. The F score is a measure of the degree of organization of an individual's personality, again on a scale of 0-100. Organized individuals with analytical tendencies will tend to score high on this scale, while less focused, expansive or practical individuals will tend to score low.
Your most probable character type is sanguine: NA (narcissistic-aggressive)
