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.

Business schools need to help students learn how to thrive under pressure. To understand themselves and their psychological vulnerability that might inhibit their ability to be effective in roles that involve ongoing complexity and duress. Preparation is essential.

Those who have high business acumen display specific, identifiable cognitive skills that permit them to perform better than their peers. Once we understand that street smarts is skill-based, we can measure it, compare it, and improve it in the general 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.

One of the capabilities, which seems to be the most difficult for aspiring leaders to maste is realistic optimism. It requires one to recognize that our experience of life is largely up to us, that our situations, good or bad, are largely due to our ability on a moment-to-moment basis to capitalize on opportunity. Those that approach life as if it is largely outside of their own control, or that others are largely to blame for their circumstances, generally find growth elusive.

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.

We never ask candidates to demonstrate their skill. We ask lots of questions about past experience, but simply looking at the results of their decisions does not let us understand the process that they used to make the choice in the first place. A good analogy is sports. If you wanted to know how well a person plays basketball, for example, you could look at statistics like shooting percentage or blocked shots. But, this is just an historical account of how well the individual played in the past - the numbers do not tell us much about how that individual plays basketball now.
