...overly intelligent leaders tend to put off potential followers by
(a) presenting "more sophisticated solutions to problems [which] may be much more difficult to understand"
(b) using "complex forms of verbal communication [and] expressive sophistication [that] may also undermine influence"
(c) coming across as too "cerebral" making them more likely to be seen as an "outsider" and not "one of us."
