Black (extraverted) ethics
Perceives information about processes taking place in objects — first of all, emotional processes that are taking place in people, their excitation or subduedness, and their moods. This perceptual element implies the ability to know what excites people, and what suppresses them. It defines a person's ability or inability to control his emotional state, and also the emotional states of other people.
When this element is in the leading position, the individual has the innate ability to induce or convey his moods to others and energize people with his emotions. He is able to activate the psychological/spiritual lives of other people and their emotional readiness for action. You might say that such a person has the ability to infect others with his moods and tends to impose on others the emotional states that he considers beneficial for their life activities.
What people usually call emotions or a person's display of emotions is neither more nor less than a form of letting out this internal excitation directly, almost without expending it in muscle activity. A cheerful person who laughs releases an emotional charge and inner excitation through certain movements of the muscles of the face and body. This might be a means for reducing overexcitement, when inner exertion cannot be used for the activity it was intended for. But it can also be a conscious method of conveying one's excitement/agitation to others — inducing one's internal excitement/agitation in the psyches of other people. Anger, for example, is also a way of reducing overexcitement, but it is usually directed not at arousing others emotionally, but at emotionally suppressing and depleting them, at lowering their activity level, or at strictly channeling their activity.
