Why can’t we talk about IQ?
That Richwine article generated plenty of heat. Truth is, everybody talks about or at least thinks about IQ all the time. At the least, every time we see somebody do something stupid, or express something without basis or thought. We also think about it when somebody says something that opens our eyes.
IQ is just one of the many personal traits across which individuals vary. It happens to be a valuable trait, but it is never determinative in life outcome. However, there is no measure for life outcome anyway. Life's outcome is death.
