According to Leta Hollingworth’s research, to be a leader of his contemporaries a child must be more intelligent but not too much more intelligent than them. A discrepancy of more than about 30 points of IQ does not allow for leadership, or even respect or effective communication. Hollingworth notes: A lesson which many gifted persons never learn as long as they live is that human beings in general are inherently very different from themselves in thought, in action, in general intention, and in interests. Many a reformer has died at the hands of a mob which he was trying to improve in the belief that other human beings can and should enjoy what he enjoys. This is one of the most painful and difficult lessons that each gifted child must learn, if personal development is to proceed successfully. It is more necessary that this be learned than that any school subject be mastered. Failure to learn how to tolerate in a reasonable fashion the foolishness of others leads to bitterness, disillusionment, and misanthropy [3, p. 259].
