It is interesting for me to note -- as a purely anecdotal personal observation that is no way supported by any scientific or quantitative evidence from a credible source whatsoever:
The people that I consider the most intelligent and/or smart in various general and specific ways also seem to be the most given to not want children (and some go so far as to get operations that effect this biologically). Many others further down the distribution of "smart people" are inclined to have fewer children, and have them later.
In other words, in my personal life experience there is a very strong inverse correlation between the intelligence of people and the amount of children they have or will tend to have, and that's assuming they have children at all. The intelligent folks I have met seem to be the only group where a total rejection of childbearing exists to a statistically non-negligible degree, to put it mildly.
No, not politically correct at all, and, perhaps unsupported by bodies of evidence other than my own (mis?)perceptions.
But I don't think I'm the only one who has noticed this.
I've heard this argument before, and while there might be something to it, I think it's more specific to say that ambitious people tend to have fewer children. This makes sense purely in terms of time commitment: the more time is devoted to raising children, the less will be devoted to one's startup, research, political ambitions, etc.
This doesn't necessarily mean that more intelligent people will have fewer children, as it's more of a question of prioritization than of ability. It does probably imply a weak correlation (smarter people tend to like to use those smarts), but there are certainly many intelligent people out there who value their children more than they value their personal ambitions. (While this is certainly not a given... consider your parents!)

This is a wildly different situation than existed even 100-200 years ago. Gregory Clark has some historical data on the industrial revolution, if you're interested.
