Interesting comments. I will say that I still think my point about our linguistic frame regarding belief (and our beliefs about our own beliefs) as opposed to an action-oriented frame is confusing to me.
Without pragmatic grounding what are we ever even talking about, our untested ideals? Action in the present moment is the important bottleneck to consider in my opinion.
Your comments reminds me how recently I sort of made a triadic taxonomy of "types of values" (value in general, like a replicating bias). I think it was (1) parasitic values, (2) self-sacrificial values, and (3) circular (stable) values.
But again using the principle of thinking of things not through any singularity sort the frame but allowing extension and similar concepts we can seem some interesting properties about this dynamic.
Let think of things as a stratified hierarchy of values having tendency that higher up strata mean a larger spatiotemporal perspective (I guess once space and time are completely abstracted then the hierarchy is more about scaling in semantic space in general.)
Parasitic values are biased toward limiting or even eliminating the replication of other lower level values. I guess this is analogous to a neuronal group acting as an inhibitory module.
In the example of antinatalism the specific value of antinatalism is oriented toward limited or stopping what we could call the self-preservation or Darwinian value (a biological value, aka instinct). Of course it depends if one wants humanity totally extinct or just down to a small number. I would agree that a degree of this inhibition is good (maybe "parasitic" is too negatively connoted a term to use)
This is interesting because the value is stratified on top of the self-preservation value and so if it succeeds in any large degree in becomes self-undermining. This is like human's killing off their ecosystem on which they are stratified.
This is really the extent of my thought on this (you probably can complete the analogy with (2) and (3)). Also it will be interesting to think through the implications of feedback from the higher strata to the lower.
