I never said it was unrelated to commuinties or species. If you want to engage in an intellectual discussion with me you, you're gonna need to step up your level of precision.
You said that non-reproductive members of a group larger than family cannot improve the fitness of reproductive members. If a man never has children, but invents an industrial process which greatly improves the efficiency of growing food, allowing larger populations to be sustainable, has he not by definition improved the fitness of all those that reap the benefits of the process?
I'm sure you're capable of following my reasoning, if you focus...
1. I claimed that Fit=reproducing offspring that also reproduce
2. You claimed that wasn't the case in societies where individuals could improve the sucess of their community/species.
I'm not denying claim 1 by also stating claim 2. I accept your definition of fitness. I'm saying that in addition to it, non-reproductive members can improve the fitness of others.
3. I generally (but not categorically) rejected this claim with regard to communities. Let me explain why. The smaller the community, the more plausible, or at least testable, your hypothesis is. If we're talking about a tribe of 200 people, it is at least possible to test if non-reproducing members can improve the spread of their gene-pool. However, even in that case, it would take a very massive and extensive level of observation to test, and even then it would be extremely diffuclt to limit other variables. If we're speaking of "community" as in modern nation-states (or even modern cities, or large neighborhoods), then the theory becomes so weak that it can be dismissed outright because a. the impact of the individual becomes virtually impossible to measure and therefore the hypothesis is untestable (and thus is a bad hypothesis) and b. depending on the behavior or action you have in mind, the impact on the gene pool is likely too broad (i.e. it won't just be benefiting those with a high gene-match).
The "species theory" is even more absurd, since obviously expanding to the entire human gene-pool exasperates the problems the "community theory" has exponentially.
I think you're fundamentally confusing testability and falsifiability. A hypothesis can be valid, albeit perhaps not too meaningful, even if the resources, mathematics, etc aren't yet available to test it. Gravitational waves had been postulated to exist for over 100 years, and prominent physicists tried for a long time to detect them to no avail. That would be a "bad hypothesis" according to you, yet they were detected just last year thanks to better technology.
However, a hypothesis cannot be valid if it is by design not testable, e.g. "Black metal has good riffs but they are impossible for human beings to observe".
If you have a specific reason to believe that inclusive fitness is by definition untestable, please provide it.
Of course. But nothing I said implied otherwise. No idea where this is coming from.
If biological traits (meaning heritable alleles) involved in forming and/or maintaining human society exist, and if human society generally improves the fitness of those that participate in it, then how is that not an example of individuals (the people possessing the traits) improving the fitness of all those within society?
Fitness applies regardless of scientific changes. Even if 100% of women chose their sperm from a sperm bank, the theory would still apply. Whichever attributes women selected would be the ones that would then qualify as fit. The universality to all life in all environmental conditions is much of the beauty Darwin's theory.
As for Social Darwinism, it is a pseudoscience, and if you doubt me just look up the history of its use for yourself. I find it boring debating verifiable facts with someone who has Google.
Applies to what? I'm not trying to change the definition of fitness or saying that it goes away just because social hierarchy and non-biological modes of inheritance exist. I'm saying that in a social and political context, there is a benefit to selecting for those that improve the viability of society at the expense of those technically more biologically fit.
And again, it's not a pseudoscience because it doesn't pretend to be a science. That's like calling religion a pseudoscience; Creationism when taught as if science, sure. "Thou shalt not kill", not pseudoscience. Social Darwinism is broadly just an argument that aspects of society, such as free market forces, should be used to reduce the fitness of those that cannot compete according to rules of said society.
