Because you have been mentioning IQ scores too often for my comfortThe reason I mention IQ so much is because of any single characteristic measured about people, IQ is the single biggest predictor of success (defined as ability to achieve academically and in employment). This is true of individuals and of nations and ethnic/racial groups. Now does this mean IQ always predicts ones success in the working world? Of course not, other factors such as creativity, personality traits such as tenacity, and luck come into play. But higher IQ people as a group certainly do better than those groups who have lower IQ's. IQ (and things correlated with it) successfully explain a host of things, things not explained by any other theory of social development without a host of complicating fudge factors that are often nonsensical. Families were larger just a couple of generations ago and that they are now smaller isn't due to everyone becoming smarter over that time. Strictly speaking that is not true thanks to something known as the Flynn Effect. But even that aside, yes, it is true that birth rates are lower now than they were in the past, particularly during the Baby Boom, but just before that the US experienced a generational trough due to the Great Depression (people were having fewer children). Even though before the Depression, birth rates were higher during than during the boom, this can be explained by the appearance of birth control. And, in the States, as far as the CDC has been keeping records, the black birth rate has significantly exceeded that of whites (see here for recent lifetime birth rates – note how the white birth rate hovers around the replacement value of 2.1 children born per child-bearing woman, and is exceeded by most minorities -- in the case of Hispanics, greatly exceeded). So while it is fair to say that overall birthrate in any given era is not determined by IQ, the relative birthrate certainly is correlated to it. |
