But you’ve reduced population IGF. you share almost all genes with other humans; our variation between each other is relatively tiny. if you’re trying to maximize IGF of your difference with other humans, perhaps you’re right; but that’s an evolutionary defect strategy. if instead you want to maximize your cooperation group’s survival to deep time, you want to broaden your cooperation group and ensure redundancy of mutual aid.

Hamilton showed mathematically that, because other members of a population may share one’s genes, a gene can also increase its evolutionary success by indirectly promoting the reproduction and survival of other individuals who also carry that gene. This is variously called “kin theory”, “kin selection theory” or “inclusive fitness theory”. The most obvious category of such individuals is close genetic relatives, and where these are concerned, the application of inclusive fitness theory is often more straightforwardly treated via the narrower kin selection theory.
Hamilton’s theory, alongside reciprocal altruism, is considered one of the two primary mechanisms for the evolution of social behaviors in natural species and a major contribution to the field of sociobiology, which holds that some behaviors can be dictated by genes, and therefore can be passed to future generations and may be selected for as the organism evolves.
Although described in seemingly anthropomorphic terms, these ideas apply to all living things, and can describe the evolution of innate and learned behaviors over a wide range of species including insects, small mammals or humans.
As of 2015, the typical difference between an individual’s genome and the reference genome was estimated at 20 million base pairs (or 0.6% of the total of 3.2 billion base pairs[cite]
Evolution selects for genes that increase their frequency in their gene pool. That’s all it does. IGF, if it’s trying to impute values to evolution, would have to be precisified to refer to inclusive genetic relative fitness, i.e. inclusively (of kin) increasing one’s relative offspring count, i.e. the frequency of one’s genes in the gene pool. It’s reasonable to approximate this as increasing the number of one’s descendants, and descendants of family members weighted by relatedness; but that approximation breaks down to the extent that your actions can meaningfully affect the total population.
I mean, I’m totally with you on optimizing for the thing you’re talking about, rather than selfish-gene-inclusive-relative-fitness. But that’s a deviation from “what evolution is optimizing for, if anything”.
If only relative frequency of genes matters, then the overall size of the gene pool doesn’t matter. If the overall size of the gene pool doesn’t matter, then it doesn’t matter if that size is zero. If the size of the gene pool is zero, then whatever was included in that gene pool is extinct.
Yes, it’s true people make all kinds of incorrect inferences because they think genes that increase the size of the gene pool will be selected for or those that decrease it will be selected against. But it’s still also true that a gene that reduces the size of the pool it’s in to zero will no longer be found in any living organisms, regardless of what its relative frequency was in the process of the pool reaching a size of zero. If the term IGF doesn’t include that, that just means IGF isn’t a complete way of accounting for what organisms we observe to exist in what frequencies and how those change over time.

True, but it’s very nearly entirely the process that only cares about relative frequencies that constructs complex mechanisms such as brains.
