What is the term for humor that feels spontaneous, warm, and is considered "second nature" to a master educator?

The term that describes humor which feels spontaneous, warm, and is seen as "second nature" to a master educator is unconscious competence. This concept refers to a state in which a person has mastered a skill or behavior to such a degree that they can perform it effortlessly and without conscious thought. In this context, a master educator uses humor seamlessly in their teaching, enhancing the learning environment and engaging students without having to deliberate on the technique or strategy.

This level of competence comes after progressing through various stages of learning, wherein an individual moves from being unaware of their lack of skill (unconscious incompetence) to being aware but still working to develop the skill (conscious incompetence), and then to proficiency with awareness (conscious competence) before reaching unconscious competence. It embodies a natural ability that contributes to the teacher's effectiveness and connection with students.
