General competence requires three necessary conditions: a) High general intelligence or IQ, b) the ability to be objective, even in situations where the result of your conclusions may not be to your liking, and c) the ability to reach conclusions without being influenced by others (i.e. independent thinking). The latter two conditions are a direct result of how the human brain interacts with the environment. The mechanism behind it is too complicated to describe here, but in simplistic terms it can be said that humans range in their relationship with reality from the emotional-outward/subjective to the introspective/objective. This variable, like all evolutionary traits, including IQ, is normally distributed. This has rather disturbing implications which may be difficult for some people to understand.

Now let’s take a look at the other variables, i.e. objectivity and independent thinking. Those two are correlated and... are normally distributed, much like IQ, with most in the middle and fewer toward the extremes in both directions. On one side of the distribution are people who, to state it bluntly, are incapable of thinking objectively about any issues that may interact with their personal views about anything at all. They can be competent in a limited field which is “neutral” to them (such as databases), but not involving anything else...They can’t run a city, a country, a military campaign, an economy, or anything requiring general competence, except into the ground, regardless of their intelligence. These people are clearly not suitable for general/high-level competence jobs.

The importance of this cannot be overstated. This group, whether we define it as 1.5% of the population or 8% of the population, is extremely valuable. This is essentially the only group in society that can reliably evaluate complex situations and make subsequent rational decisions. Without it, modern technological society simply cannot be built or maintained – let alone advanced. Let me rephrase this – if we do not identify and utilize this group, we cannot run our complicated societies except into the ground.
