The Idiocracy argument is as idiotic as the future it claims is likely. In reality, this has always been the case. IQ doesn't mean what you think it means, but let's avoid that for now. Several studies on the hereditary effect of IQ have been fairly inconclusive. There's pretty wild fluctuations and the closest to a predisposition tends to be normal IQ range parents having normal IQ range kids. In other words, stupid people having stupid kids doesn't really work that way. Adding to this, intelligence is a highly environmental factor and somewhat of a choice. If you're looking around and seeing morons that's probably because a lot of people around you choose to be stupid. Much like how your brain is clearly choosing to let in only the most ignorant thoughts it can. Alternatively, it's an indicator of a failing school system. While the nature v nurture debate is still out, we can clearly say that knowledge is not hereditary. And that's a far better indicator of a person's worth to society than any culturally biased quotient exam ever was. Oh, and by the way, IQ scores have been steadily rising for centuries and the trend has been continuing. People today are smarter than they were 200 years ago. Who'd a thunk it?
