What you've articulated resonates strongly, but I suspect the distinction you're pointing to (evidentiary norms in science vs the preformal heuristics guiding scientific practice) only scratches the surface of a far deeper structural misalignment. The deeper problem, as I see it, is that we lack a coherent theory of pre-paradigmatic cognition (i.e., a formal account of how conceptual priors/aesthetic heuristics/anticipatory abstractions function PRIOR to stabilization within institutions.)

So the core tension is between epistemology as a theory of justification or as an architecture of generativity (the former governs what counts as knowledge; the latter shapes what becomes thinkable before it becomes provable). We're still quite epistemically illiterate about the second (and this ignorance begins to show especially in fields like AI where the frontier progressively consists of ontologically ambigious objects such as gradients/embeddings/emergent capabilities and architectures that have no firm referents in either nature or math.) What you're describing as scientists' reliance on "hunches" is a form of cognitive structure beyond a simple heuristic in that it functions more like a proto-taxonomy for world-model constructions in domains where empirical anchoring is delayed or fundamentally soft.

As for the borrowing from analogical fields such as evolution/cognition/language, it's useful because it serves as a generative constraint that allows high-dimensional exploration without epistemic collapse. The fact that such constraints don't cleanly fit publication standards I think is less a defect of the constraints themselves but more a recognition of impoverished formal infrastructure for representing proto-theoretical cognition, which is why I believe the invocation of philosophy of science is suggestive but arguably not sufficiently radical. I would take it a step further and suggest a re-engineering of the "cognitive contract" between our discoveries and their validation. Our present pipeline (where insights shall pass through empirical formalism before they can be recognized as epistemically legitimate) appears to amputate fertile forms of abstractions. In domains where feedback is sparse/referents are emergent and the ontological status of the research object is itself under construction I think we shouldn't conflate our methodological constraints with epistemic sufficiency. AI is a notable case here, but the same holds for climate modeling/synthetic biology /quantum foundations/consciousness studies, etc.

I therefore believe in this light that the role of philosophy shouldn't be to "adjudicate from the sidelines" but instead to operate as a meta-generative layer that co-evolves with the science it seeks to clarify. Until we take this project seriously we'll continue to be epistemically confused and treat perhaps the most important cognitive substrates of discovery as informal noise.

I find the anthropic reasoning to be structurally incoherent when evaluated with rigorous probabilistic reasoning. Conditioning on the fact of existence does not dissolve the explanatory asymmetries introduced by fine-tuning nor does it render hypotheses about design/multiverse/underlying law epistemically inert in any way. That's an illusion that arises from conflating necessity of explanation with inevitability of observation (yet these are not interchangeable categories).

I don't think it quite hits the target because the real question isn't how probable is it that we'd observe a universe compatible with our existence - as that is trivially true and obvious - of course we only observe such universes. That, however, was never the engine of the inference at issue.

The real inferential fulcrum is comparative, namely: how much more probable is a life-permitting universe under a design/multiverse hypothesis, versus under a null hypothesis of chance without structure?

Sober’s infamous formulation:

P(R | D, OSE) > P(R | ¬D, OSE)

is rejected by some on the grounds that both sides allegedly reduce to 1 due to anthropic inevitability. But this is a mischaracterization of what’s actually being conditioned on. It stems from a confusion between indexical necessity and probabilistic expectation. The fact that we observe fine-tuning is not the same as asserting that it is guaranteed under all hypotheses. Observation selection constraints are not symmetry erasers; they are filters applied over distributions. You still need a distribution to filter over.

When the only information you account for is “we observe that we exist,” you obliterate the probabilistic structure you’re trying to reason about. This is what I call "probability laundering" - i.e., you sneak structure into a tautology and pretend nothing remains to be explained.

The implicit claim that the existence of observers guarantees their post hoc astonishment is meaningless because wherever observers do arise, they'll naturally observe favorable conditions - but this collapses as it treats observer existence as a universal selection function rather than a hypothesis-sensitive outcome. Consider, arguendo, two hypotheses:

H1: A single-roll universe with no fine-tuning mechanisms.

H2: A structured universe or multiverse that probabilistically amplifies life-permitting conditions.

Under H1, the likelihood of observers conditional on the base parameters is vanishingly small. Under H2, it is orders of magnitude higher. When you discover you’re in a universe fine-tuned for life, Bayesian updating must favor the hypothesis under which such a discovery is less surprising. That’s not nullified by the fact that you could only have made the observation under favorable conditions. It’s precisely because such conditions are rare under H1 that the observation carries inferential weight.

It’s the same logic behind any conditional probability inference. Suppose I survive a rare disease after an experimental treatment: it’s no rebuttal to say “Well, you couldn’t have observed otherwise - you’re only alive because the treatment worked.” Sure - but that survival is still stronger evidence for treatment efficacy than against it.

And, finally, perhaps the deepest flaw here (and in much of the anthropic literature post-Carter) is the collapse of epistemic granularity. That is, if we treat observer selection effects as categorical absolutes (rather than filters over structured distributions) - then no observation could ever update our beliefs on the nature of physical reality - which is epistemically fatal. Worse - if anthropic reasoning is always sufficient, then ANY observed structure becomes vacuously necessary, which immediately erodes the boundary between explanation and observation. We might as well assert that "Of course the laws of physics look elegant - we wouldn't be here if they didn't" - but that is the ultimate Copernican anti-shift - it turns us back to epistemic geocentrists who imagine our observations are self-justifying.

If a theory predicts nothing but observers in observer-compatible worlds, it’s not making a prediction - it’s making a category statement, and that's unfalsifiable. Science dies under that standard.
