Some would posit that ones IQ is determined by their ability to remember things.
Some speculate I.Q. is ones ability to recite arbitrary facts (or our current understanding which we call "facts") on demand.
Still others believe that I.Q. is determined by ones race or genes more so than their culture.
But what is I.Q.?
I.Q. is the ability to adapt, to evolve to ones short term surroundings without doing harm to ones long term environment.
I.Q. is the ability to reconcile oneself with that which already exists.
I.Q. creates, consumes or builds what is necessary without overbuilding to ones detriment.
I.Q. is being without subjugating other beings.
