Should humans try to selectively distinguish certain breeding stock so that more highly intelligent children can be raised in the future? Think about it a little, if someone with an IQ of 110 breeds with someone that has an IQ of 90, then the children are more likely to be in the middle due to the genetic basis of gray matter in the brain being strongly correlated to IQ (assuming they were raised in a standard environment). However if someone with an IQ of 110 chooses to breed with someone that has their IQ, it would effectively create a child similar to them. So let's that nearly everyone in the world chose option 1, it would round out both those in the higher and lower brackets to constitute an average that would be less diverse in the ranges of IQ, meaning that the averages of 68% being between 85 and 115 would be lowered down to 90-95 and continually drop from that point due to lower IQ populations breeding at a much higher rate than higher IQ populations. Where would the smart people be then? Instead of doing that, we could judiciously breed a population of elite so that human growth won't stagnate.
Thoughts on this?

no one has any thoughts on this huh?
Things don't average like that.
A couple with IQs of 110 and 105 can have a child with an IQ of 130. That doesn't mean all HIS kids will be smart. Look up "regression to the mean". Likely they'll be a disappointment to him.
It's true that if the stupid have more kids, the average IQ of the human race will drop. But regression to the mean works in the other direction as well. Two stupids can have a kid smarter than either parent. Because intelligence is the result of multiple genes, not a single one, it'll take a very long time before there'd be a noticeable change.
Cultural & technological factors operate much faster. Facebook and Twitter are making people dumb even without any change in the gene pool.
For a look at what the long term results of genetic "dumbing down" might be, read "The Marching Morons" by C, M. Kornbluth.
1. Human beings already selectively breed with those who they perceive to have superior genetics.
2. You are forgetting about genetic mutation. If your model was correct then evolution wouldn't exist.

lol
>parents have a dumb kid
Regression to the mean!
>parents have a smart kid
Regression to the mean!

Doesn't the success of the Ashkenazim indicate that it is possible to increase the IQ of a group by selecting for intelligence? I imagine that the first Jews to immigrate to Europe were, as a group, at least somewhat below the European mean. A thousand years of selective pressure later, and they're a SD above the mean. And this happened all under "natural" conditions. What if humanity conducted an intensive breeding program similar to the Balyayev Russian domesticated fox program? Considering that intelligence and fertility are inversely correlated, wouldn't it be a good idea to produce an elite population before the world becomes overrun with brainlets?
Myself, I do think that the Ashkenazis are a particularly interesting case because they have indeed
maintained their IQ successfully by carefully selecting for intelligence, but what is odd is that they
have very high rates of schizophrenia and an abnormal skull structure compared to just about every
other ethnic group in the world.
Perhaps, but that's beside the point.
don't most people do this on their own anyway? try to select a partner from good stock? at least in the absence of modern propaganda....
No. Women are attracted to status above all. Intellect may or may not help you to achieve status. Consider that Mick Jagger has 8 kids to 5 women and Terry Tao has 2 children to one woman.
