FYI, my wife’s actual profile showed this; more precisely, IIRC it rated her as 44% Explorer, based on the traits given. It did not show what percentages the other 5 boxes broke down to, and I don’t know whether those factors were also taken into account in the analysis. (I also don’t know what precisely the percentage represents; i.e. is it a probability, a “percentage of your traits”...?)
Better, but still not good enough. If it is a mixture, what about the other 56%? Which 44% of the explorer traits? If it is a confidence level, the model doesn’t seem to rate itself very highly, so why should I be impressed with it?
From what I read in his book, he describes the types in terms of basic strategies for responding to the environment, where there are only a few good choices to make. IOW, the stereotypes are supposed to represent stable strategies for responding to infections, shortages, and other stressors. That is, there are not an unlimited number of ways to do things in those areas, so you end up with large clusters.
Suppose there are 2 stable strategies that each say how to deal with several specific problems, such that either of the 2 strategies work but a mixture somehow fails. These strategies, being complicated, are coded for by multiple genes. Suppose a man with one strategy and a women with the other strategy mate and have offspring. Those offspring are going to inherit some mixture of the two strategies, even discounting complications such as being heterzygous where the parents are homozygous, and therefore will employ an unfavorable mixture. You can not have multiple non mixable complicated traits in a sexually reproducing population, without tricks like having each member have the complete code for all possible traits, and a varying gene that switches on one of them, which we observe in sexual dimorphism at not much otherwise. Eliezer has written of this.

But we do observe epigenetic traits—variations in gene expression based on environmental conditions, such as genes that act differently depending on how much exercise you get, or the level of testosterone in the fetal environment, or various other things.. D’Adamo’s claim here is that his typing groups are a combination of gene inheritance and gene expression, and his notion of “strategies” isn’t really the same as say, having a completely different way of digesting foods.
It’s more like identifying which places to store fat in first—something that (IIUC) we already know is heritable. The fact that fat gets stored isn’t changed, just how much, where, and how quickly. Something like that can make a big difference on a practical level to a person’s life, without being a particularly complex adaptation in itself.
