I recommend that gifted leaders be encouraged to develop their natural tendency to
grasp, incite, forge, and transform.
Alternatively, we could just recognize this as the HR and marketing fluff that it is. Developing leadership skills with tried-and-true rules to follow has nothing to do with natural aptitude, nor is charisma intellectual giftedness.
If a gifted person has leadership ability, so much the better for them, of course. But it's obvious to me why the sometimes-repeated "leadership capacity" wording appears in the Marland Report and was subsequently adopted in some legislation, such as the Javits Act: it allows inclusion of some non-intellectually-gifted people, and also simply because it makes polticians, who are leaders themselves, feel good.
