Black (extroverted) intuition
Perceives information about objects' potential energy — for example, information about the physical and mental abilities and potential of a person. This perception grants the ability to understand the structure of objects and phenomena and grasp their inner content. This element determines a person's ability or inability to see the real potential energy of one's surroundings.
When this element is in the leading position, the individual has pronounced cognitive interests. This individual is constantly studying underlying phenomena, which he/she is able to communicate to others quite successfully by making complicated things simple. Such a person enjoys explaining his understanding of things to others. Under favorable conditions, he/she becomes a scientist or writer. He/she can find optimal ways of increasing the potential energy of objects. "Energizes" other people around him with his understanding of the possibilities and potential of the surrounding objects.
