Giving dumb people cute robotic kids would not work. They would probably have sex anyway, which is the part we want to avoid here. It requires some intelligence to understand the relation between sex and reproduction, and even higher intelligence to remember it when the opportunity for sex becomes immediate.

Sex = pregnancy risk is pretty straightforward. You would have to be literally retarded to not appreciate it.

Pregnancy rates varying with IQ is more about culture and SES than "how girl get pragnant how is babby formed" - they get pregnant to hook their boyfriend, because the guy insisted on sex without protection, because unprotected sex is a sign of trust, because having a baby gives meaning to their life, because everyone else is, because they left contraception at home and the passion of the moment is too strong etc. (If these reasons are completely alien to you, well, that's an example of the culture thing. I found reading Promises I Can Keep: Why Poor Women Put Motherhood Before Marriage really interesting.)

None of those are because they don't understand the "baby comes 9 months after sex with a man" theory; it's worth noting that even indigenous tribes suffering from iodine deficiency and endless infectious diseases and all sorts of problems like that all understand that sex causes pregnancy.

Not everybody makes the link:

But the most fascinating and strange part about the islanders are their beliefs on the subject of pregnancy, also described in Malinowski’s classic article “Baloma: The Spirits of the Dead in the Trobriand Islands”. When people die, you see, their spirit takes a canoe to the island of Tuma, which works very much like the normal island except everybody is a spirit of the dead. When the spirit gets old and wrinkled it shrugs off its skin and turns back into an embryo, which a spirit then takes back to the island and inserts into a woman. This, you see, is how women get pregnant.

That’s right. The islanders do not believe that sex causes pregnancy. They don’t believe in physiological fatherhood. Malinowski was incredibly skeptical about this, so he tried all sorts of ways to see if this was simply a story they told, while they actually the real deal. But no, they assured him that it was really true, that all the white people who insisted otherwise were being silly, that the spirits caused pregnancy, not sex.

They argued the case quite logically. After all, they noted, one fellow went on an expedition for a year or two and when he came back, he had a new son. He obviously wasn’t having sex with her while he was away, so where did the kid come from? (Cough.) And, they note, there are some really hideous people on the island who nobody would dare have sex with, yet they manage to become pregnant. (Malinowski spies some kids looking sheepish when this subject is raised.)

They also argue the other way: people on the island are having sex all the time from a very early age and yet they very rarely get pregnant. (Naturally, the islanders don’t practice any form of contraception; the very idea doesn’t make sense when sex doesn’t cause pregnancy.) The white man’s argument just doesn’t make sense. Indeed, recent visitors report, the islanders still believe that sex doesn’t cause pregnancy, despite the best efforts of health workers.

You know, it's funny - before typing that I thought to myself 'didn't I read about one very obscure tribe in the whole world & history which had managed to not believe that men impregnate women?' but after thinking about it for a little while and doing some Google searches, all I could think of was that weird tribe in Patrick Rothfuss's Kvothe fantasy novels who don't believe in 'man-mothers'.

Like Randy, I'm always a little skeptical of these things lest there be another Mead/Samoa incident, and assurances like

Don't necessarily resolve the issue especially since the data was from so long ago. But looking in Wikipedia, I see nothing disagreeing and an interesting mechanism:

Although an understanding of reproduction and modern medicine is widespread in Trobriand Society, their traditional beliefs have been remarkably resilient. The real cause of pregnancy is always a baloma, who is inserted into or enters the body of a woman, and without whose existence a woman could not become pregnant; all babies are made or come into existence (ibubulisi) in Tuma. These tenets form the main stratum of what can be termed popular or universal belief. If you question any man, woman, or even an intelligent child, you will obtain from him or her this information. In the past, many held this traditional belief because the yam, a major food of the island, included chemicals (phytoestrogens and plant sterols) whose effects are contraceptive, so the practical link between sex and pregnancy was not very evident.[2]

So it sounds genuine. Still, one indigenous group out of the many thousands studied demonstrates the point: everyone understands the connection between sex & pregnancy.

I've heard similiar stories before that ended up being due to the westerner's credulity rather than the islander's ignorance.
