It’s not necessarily intelligence that makes someone a great leader. There are other factors, and you don’t have to be born with them.
Do smarter people make better leaders? Although the general answer is “yes,” it depends on what you mean by “smart.” Almost a century of research on basic intelligence (what is referred to as “academic” or “verbal” intelligence – better known as IQ) suggests that IQ is slightly to moderately related to attaining a leadership position and to leader success. But that doesn’t always fit with people’s experience.
