Spiteful mutants

Social Epistasis Amplifies the Fitness Costs of Deleterious Mutations, Engendering Rapid Fitness Decline Among Modernized Populations

Deleterious mutations are typically understood exclusively in terms of their harmful effects on carrier organisms. But there are convincing reasons to think that such adverse effects are not confined to the individual level. We argue that in social species, interorganismal gene-gene interactions, which in previous literatures have been termed social epistasis, allow genomes carrying deleterious mutations to reduce via group-level pleiotropy the fitness of others, including noncarriers.

Personally I think that’s nature’s IQ test, but go on.

(If you can be talked out of your instincts, you don’t deserve to breed).

This fitness reduction occurs by way of degradation of group-level processes that optimize the reproductive ecology of a population for intergroup competition through, among other mechanisms, suppression of free-riding.

If you can be talked out of it by people who hate you…

Such damage to group regulatory processes suggests a hidden role for the accumulation of behavior-altering “spiteful” mutations in the dynamics of the demographic transition—these mutations may have contributed to the maladaptive outcomes of this process, such as widespread subreplacement fertility.

Hmm. Not really. Multi-factorial.

A structured population model is presented describing aspects of this social epistasis amplification model. This phenomenon is also considered as a potential explanation for the results of Calhoun’s mouse utopia experiments, which provide an opportunity to directly test a major prediction stemming from the model.

Discouraging breeding is spiteful mutant if the host does it themselves, particularly from their own inability (no mate) rather than true choice. Picture all the women running round babying tranny feels.
If not, could be eugenic if encouraging the unfit only to abstain OR environmental, as desire for a family drops for group survival temporarily based on crime level and as high trust society becomes low trust; although GDP is an important consideration, for men as provider, moreso than women.

There’s also a connection to solar cycles and crops/food availability. Nobody’s sure if white people can sense it. Needs a study. But birth rate is tracked quite well to solar cycle, if you look.
