Bill Gates is obsessed with IQ (he also released software with bugs, so he could corner the market - which accounts for those endless updates - and also allegedly used to release bugs in his software that made other browsers crash). The military is obsessed with IQ. Schools are obsessed with it. Lots of people are.
There is a lot more to life than having a high IQ.
This quote is from the No Ma'm blog.
"It is an outrage that they should be commonly spoken of as Intellectuals. This gives them the chance to say that he who attacks them attacks Intelligence. It is not so. They are not distinguished from other men by any unusual skill in finding truth nor any virginal ardour to pursue her. Indeed it would be strange if they were: a persevering devotion to truth, a nice sense of intellectual honour, cannot be long maintained without the aid of a sentiment which Gaius and Titius could debunk as easily as any other. It is not excess of thought but defect of fertile and generous emotion that marks them out. Their heads are no bigger than the ordinary: it is the atrophy of the chest beneath that makes them seem so." ~C.S. Lewis, The Abolition of Man
This one I've know for years.
"But as the wise Solomon said, wisdom enters not into a malicious mind, and science without conscience is but the ruin of the soul, thus it behooves you to serve, to love, to fear God, and on him to repose all your thoughts and all your hope, and by faith formed in charity to adhere to him, so that you may never be separated from him by your sins." - François Rabelais
