In one of my posts on the Age of Malthusian Industrialism, I pointed out that groups such as the Amish and the Mormons will be some of the first to become saturated with genotypic breeders:
This acceleration will be noticed first, and remain most pronounced – at least in relative terms – amongst already highly fertile tribes, such as the Amish, the Haredi Jews, and possibly the Mormons. They will become even more fertile and will see their numbers multiply fastest. However, their very low initial base precludes them from ever accounting for a substantial percentage of the world population, and this goes double for any of the marginal religious breeder sects.
Now, here is a map of how this may look like, courtesy of /pol/*:
Projecting forwards another century after 2100, and Mormonism may well have come to dominate the entire Western US, as opposed to just its Mountain heartlands.
The highest Amish range on this map is 8.1%-17.2% (dark green), versus 50%-66% (dark red) for the Mormons. So the Amish would not be dominating the Eastern US come 2120 like the Mormons would be in the Western US – or at least its non-metropolitan parts. By that time, the breeder transition should be in full swing even amongst the “normie” population, so the percentage of Amish should reach an asymptote well before they get anywhere near a majority in the Eastern US.
Despite their many strange beliefs and behaviors, I do not have a negative attitude towards Mormonism. It is in many respects the quintessential – and ultimate? – Anglo religion. As I pointed out on Robin Hanson’s blog, it is also highly compatible with transhumanism. Once the dysgenic dark ages of the third millennium are replaced by the reassertion of Malthusian selection for intelligence, conscientiousness, and frugality, we might expect this LDS civilization to be one of the first to reignite space technologies.
