Leadership Traits: Intelligence
Leadership requires intelligence, yes, the plain old IQ kind. Ram Charam recently used the term “intellectual bandwidth.” Leadership, particularly during change, requires several components of intelligence: IQ, mental complexity and complex time span.
While it has been popular to talk types of intelligence, as yet, instruments that establish other “intelligences” as separate artifacts from IQ and personality are not sufficiently validated to use other than as feedback tools.
What we know is:
Think about this one from your own experience. How would you feel if it were clear that your boss didn't understand the complexities of the business. Suppose you had to constantly simplify and explain things to the boss. It would get old fast and you would probably think you'd make a better boss than the person with the job. And that might be true.
Employees with greater intelligence and/or a longer time horizon for mapping out consequences of actions are often frustrated working for a boss who can't keep up. These employees with either post within the organization for a different job, or just leave and take their intelligence with them.
