Entropy–Curvature Dynamics,
Introduction: Why “Post-Hoc” Accusations Matter

In contemporary cosmology, accusations of “post-hoc” reasoning are increasingly used to dismiss frameworks that appear to align with newly emerging data. These accusations are not trivial. They directly concern the epistemic integrity of a theory—whether it predicts, constrains, or merely rationalises observations after the fact.

The arrival of high-resolution early-universe data, most notably from the James Webb Space Telescope (JWST), has intensified this scrutiny. As observational results challenge long-standing assumptions, theoretical responses are often judged not on their structure, but on their perceived motivation. In this climate, any framework that appears relevant after JWST risks being labelled retrofitted by default.

This paper addresses a narrower but essential point: what post-hoc reasoning actually is, and what it is not. Its purpose is not to claim empirical success, nor to argue that any framework has resolved current tensions. Rather, it clarifies the methodological distinction between theories whose defining structure depends on specific data, and those whose structure is defined independently of it.

Crowton’s Cosmogenic Field Theory (CCFT) is referenced here only as a concrete example of this distinction. The aim is precision, not advocacy.

2. What “Post-Hoc” Reasoning Actually Means in Physics

In scientific methodology, post-hoc reasoning refers to explanatory structures introduced or modified because a particular outcome has already been observed. In physics, this typically takes the form of parameter tuning, auxiliary hypotheses, or ad hoc extensions whose sole purpose is to preserve agreement with data.

Not all theoretical refinement is post-hoc. Physics progresses by responding to evidence. The critical distinction lies in dependence, not timing. A framework is post-hoc when its core mechanisms exist only to accommodate known results.

A theory is genuinely post-hoc if:

· its defining parameters are introduced in response to specific observations,

· its explanatory success relies on unconstrained adjustability,

· or its scope expands reactively without prior structural motivation.

By contrast, a framework is not post-hoc if:

· its governing principles are specified independently of particular datasets,

· its predictions are structural or qualitative rather than numerically tuned,

· and its alignment with data arises from pre-existing constraints.

This distinction is often blurred in public discourse, where relevance after a major observation is treated as evidence of retrofitting. Such imprecision risks discouraging foundational work precisely when it is most needed.

3. Why JWST Has Intensified the Post-Hoc Problem

JWST has not merely refined existing observations; it has exposed structural tensions within standard cosmological assumptions. Early, massive, and morphologically mature galaxies at high redshift strain conventional timelines of structure formation.

In response, many approaches have sought reconciliation through adjustments to star-formation efficiency, feedback strength, or dark-sector behaviour. While such efforts are not inherently illegitimate, they have heightened concern over post-hoc modification—particularly where changes appear narrowly tailored to JWST outcomes.

As a result, any framework that aligns with JWST data is now met with suspicion, regardless of how or when it was formulated. The issue is not JWST itself, but the pressure it places on single-model cosmology. When one model is expected to explain all regimes seamlessly, deviations become crises, and alternatives risk dismissal as opportunistic.

This environment makes it essential to distinguish retrofitting from structural preparedness.

4. The Structural Difference Between Models and Regimes

Much confusion arises from failing to distinguish between models and regime-based frameworks.

A model typically assumes a single governing structure intended to apply universally. When discrepancies arise, resolution often involves parameter adjustment or auxiliary mechanisms. While historically productive, this approach risks drift toward accommodation as flexibility increases.

Regime-based frameworks take a different approach. They partition phase space into qualitatively distinct domains, each governed by different dominant dynamics. Transitions between regimes are not tuning choices but structural features associated with thresholds or feedback dominance.

This methodology is well established across physics. Phase transitions in condensed matter, laminar–turbulent flow in fluids, and effective field theories in particle physics all rely on regime distinctions. Observing new behaviour does not invalidate such frameworks; it identifies the relevant regime.

In this context, regime-based cosmology is not radical. It reflects a conservative recognition that different physical conditions permit different behaviours.

5. How CCFT Was Defined Independently of Specific JWST Outcomes

CCFT is explicitly structured as a regime-based framework. Its defining feature is entropy–curvature coupling as a regulatory mechanism governing gravitational behaviour across conditions. This structure does not encode numerical targets or observational outcomes.

The core principles—entropy–curvature feedback, threshold-defined regimes, and non-singular gravitational evolution—were articulated as conceptual constraints, not as responses to specific datasets. CCFT does not predict individual galaxy properties; it specifies which classes of behaviour are dynamically allowed.

This distinction is decisive. A framework that defines permissible behaviours is not retrofitted when those behaviours are observed. Alignment arises because the theory already permits such outcomes within its regime space.

JWST observations therefore do not motivate CCFT’s structure; they provide a context in which that structure may be assessed.

6. Why Regime-Based Theories Naturally Align with New Data

Scientific prediction is often equated with numerical forecasting, but this is not the only legitimate form. Regime-based theories make structural predictions: they specify which behaviours are possible, which are forbidden, and where transitions should occur.

When new observations reveal behaviour unexpected within a single-model framework, a regime-based theory may appear prescient—not because it predicted specific values, but because it anticipated qualitative change.

This is why alignment with new data is not evidence of post-hoc reasoning. If a framework already encodes the conditions under which standard behaviour breaks down, observing such breakdowns confirms scope rather than retrofitting.

As cosmology probes increasingly extreme regimes, this distinction becomes unavoidable.

7. On Prediction, Constraint, and Falsifiability

Falsifiability does not require immediate numerical precision. In regime-based frameworks, falsifiability operates through structural exclusion.

CCFT constrains gravitational behaviour by:

· forbidding unregulated singular collapse,

· defining permissible regime transitions,

· and excluding behaviours inconsistent with entropy–curvature regulation.

Observations demonstrating sustained violations of these constraints would directly challenge the framework. This form of falsifiability is explicit and testable, even if initially qualitative.

As data improves, such constraints can be sharpened into quantitative tests. Structural clarity precedes numerical refinement.

8. Addressing Common Mischaracterisations

Several recurring mischaracterisations warrant brief clarification.

“It explains everything after the fact.”CCFT does not claim universal explanatory power. Its scope is explicitly constrained.

“It was invented because of JWST.”Its defining principles were articulated independently of JWST outcomes.

“It avoids making predictions.”It makes structural predictions regarding permitted and forbidden behaviour.

These clarifications are offered to ensure critique engages with the framework as it exists.

9. Why This Distinction Matters for Scientific Progress

Periods of rapid observational advance often require conceptual reorganisation. When models are stretched to accommodate diverse phenomena, the risk is not failure but fragmentation.

Dismissing frameworks based on perceived motivation rather than structural content risks slowing this process. The relevant question is not whether a theory aligns with new data, but why.

Regime-based approaches offer one path forward. They preserve continuity while allowing qualitative change, situating established models within a broader landscape rather than replacing them.

10. Conclusion: Structural Prediction vs Retrofitting

Alignment with new data does not, by itself, constitute post-hoc reasoning. The decisive factor is whether a framework’s defining structure depends on the data it later encounters.

CCFT has been presented here not as a solution to current tensions, but as an example of a regime-based framework whose principles are independent of specific observations. Its relevance to JWST-era findings arises from structural scope, not retroactive adjustment.

This paper makes no claim of empirical validation. Its purpose is methodological: to clarify a distinction that is increasingly important as cosmology enters regimes previously beyond observation.
