Research has shown that one's level of intelligence is the single most predictive component of professional success - better than any other ability, trait, or even job experience. Yet, too often, employees are selected because of their likeability, presence, or charisma.

Often people freeze under severe pressure, but that says nothing about their ultimate capability- only their level of preparation.

The development and/or revelation of a CEO's potential for great leadership requires slow escalations of experiences that involve pressure, each time given the tools to succeed. Successful experience breeds confidence, as well as an eventual restlessness to try more.

Only recently have we begun to understand the specific cognitive skills that contribute to business success and how to measure them. Hopefully, this insight will allow us to more keenly focus our attention on indentifying and cultivating decision-making abilities in the executive population.

In a business setting, one's intelligence is crucial. Many problems faced by today's executives are unique and ill-defined. So, one's ability to analyze information and render a decision based upon the probability of success is imperative. What it comes down to is that all the knowledge in the world is useless if one has no means of processing and applying it. Organizations run on the brainpower of their people.

CEOs must master three essential attributes, realistic optimism, subservience to purpose, and finding order in chaos. One's capacity in each determines their ability to cope with today's business environment.

We often say that someone has exceptional political or social savvy, but what specific cognitive skills allow these people to handle interpersonal situations so effectively? Typically, socially skilled people are exceptional at recognizing underlying agendas, anticipating the probable effects and likely unintended consequences of a chosen course of action. These specific capabilities determine one's "people smarts."
