Please accept my humble apologies in advace for this; it is not my intent to advocate an elitist agenda or justification for social policies that do not honor the sanctity of the human spirit first and foremost above all other measures.  I realize there is risk in discussing matters that might be viewed as politically incorrect.  Please know that my intent is not to cause harm or injury to anyone; I consider myself to be egalitarian by nature and if anything I'm opposed to intelligence tests in the first place.  There are many measures of intelligence in our species, only one type of which is the standardized IQ test, which reflect only one's penchant for things cultural anyway.  There is too much that is ineffable about our universe and the human condition to place much stock in measurements of native intelligence viz. the cultural hallucination we verbally share.  Having said that....

Goff's Law:  By any measure of intelligence, half of humanity is and will always be below median IQ.

Since this observation is definitional it is presumably obvious and not meant to impugn or elevate any group or individual.  It is simply true, based on statistical axiom.   So how is this germane?

If there is a correlation between relative wealth or earning capability and IQ, which may the case, especially in a knowledge driven economy, then we must recognize that the "fitness landscape" will favor those on the high end of the median.  Which is to say that unless we do something about it, the smart will inherit the earth.  "Have vs. have not" trends will continue.  At least that seems to be true on the surface.  But in the Network Age, no one thing stands alone without the mediating influence of other factors -- the unintended consequences, if you will.

According to the World Watch Institute, most of our planetary ecological malaise is due to the activities of the wealthiest 20% and the poorest 20% of the earth's occupants.  If we recognize the correlation between wealth and IQ, then we must also recognize the correlation between ecological malady and IQ.  And since ecologies bind us all (as in, we're all connected in the end anyway),  the effects of activities that perturb the environment will be generalized to the world in toto.  In other words, it doesn't matter how smart you are or how much wealth you have if you can't breath the air, drink the water, break contaminated bread with your highly contagious neighbor, or enjoy the abundance of a planet forsaken.  Nor does matter whose fault it is.  Clearly, the responsibility for remedy lies with each of us.

Most software developers are members of the other half.  In fact, I dare say all are member of the other half.
<humor>  Their management may not be.  </humor>  But it is highly probable that if you are a software developer you sport an IQ greater than the median by any measure.  That's why you're getting the big bucks.  With that mantle, however, comes responsibilities, not the least of which is the realization that the code we write must serve all, not just the wealthy and not just the smart.  All.  Half the adults on this blue bubble can't even read.  How can wealth propagate given these observations?  Answering that question is key to understanding the scope of any effective vision we might share.
