Maybe it is a measurement of genetic goals.  Maybe people with high IQs are genetically driven towards a rational world, and people with lower IQ's are genetically driven by nature and spiritualism.                                                                                                                                ..The people with high IQ's keep pushing technology to the point where many people can't keep up.  The problem is they are destroying the planet with their high IQs.  We live in an unsustainable environment.  They can't, or won't, recognize the fact they are killing themselves, and taking the rest of us with them.  The earth cannot be pieced back together now.  It's too late for that.  The destruction does not stop.
