Who's Having the Babies?

Continuing my ongoing investigation into fertility, I wanted to take another look at who's having children. This post will look at fertility from a different angle: the spread in fertility by sex, IQ, political orientation, and education. I was prompted to this by a recent article describing parenthood in Norway. It found that a fifth... Read More

ABC News ran a story two nights ago about men and women and sleep: The story cited that women are, on average, lighter sleepers than are men, being far more easily awakened. (Now I'm sure Heartiste and a few others will have a little bit of fun with this particular video.) It featured ABC's current... Read More

A Tale of Three Maps

To demonstrate a point that I have asserted at various points – a point that tends to be often indirectly hinted at in the blogosphere and only occasionally stately concretely, I again avail to maps to tell a tale. First, I'll start with a previously featured map of fertility rates across Europe: This is a... Read More

Following up on my previous post, a commenter over at Ellen Walker's Complete Without Kids responded to my comment there with this: I wanted to see if this was in fact true.

Over at Psychology Today, clinical psychologist Ellen Walker has a blog called Complete Without Kids, which is dedicated to the modern child-free (presumably professional) adult. There, she extols and rationalizes the conscious decision to not reproduce. Of course, it's not like Psychology Today isn't loaded with the typical cutting-edge suspect psychological wisdom, and it isn't... Read More

It's Not the Cads, It's the Tramps

JayMan • December 28, 2012

• 900 Words • 11 Comments • Reply

There has been a lot of discussion in the blogosphere as of late as to whether the "cads"—i.e., low paternal investment, promiscuous (and often low-IQ) men were siring more children than "dads"—high paternal investment, monogamous, high-IQ men. While I and others have produced some evidence (primarily from the GSS) that tenuously indicates that this is... Read More

Some Guys Get All the Babes - Not Exactly

JayMan • November 8, 2012

• 1,900 Words • 24 Comments • Reply

A common theme that circulates in the HBD/Game blogosphere is that, in the wake of the sexual revolution, an increasing number of men end up mateless, thanks to the fact that a minority of men ("alpha males") monopolize most of the women. A commentor over at Peter Frost's blog even attached his own made-up numbers... Read More

Commenter redzengenoist has brought to my attention that in his homeland of Denmark, policy seems to have accomplished two rather remarkable feats: Fertility among non-Western immigrant women (primarily Muslims) is down to 1.88 children/child-bearing woman, from a high of 3.4. And, more importantly, the fertility rate among educated Danish women has nearly caught up to... Read More

Following up on my three previous posts, I want to talk again about what to do with this HBD knowledge.

Ron Gunhame over at Inductivist has an interesting post looking at out-of-wedlock births had by Americans, by political orientation. By looking at the GSS data, he seems to have found that among the never married, conservatives were far more likely to have children. This is interesting, for one, because of its implications for my "pioneer... Read More
