Abstract
This paper presents the fourth and final installment in our series of external validations for the Theory of Domain-Coherent Systems (ToDCS), focusing on the empirical findings from the multi-institution paper "Evaluating the Goal-Directedness of Large Language Models" (Everitt et al., 2025). This research provides the critical experimental evidence that bridges ToDCS from a theoretical and mathematical framework to a practical, observable phenomenon in state-of-the-art AI systems.
We demonstrate that the paper's central metric, "goal-directedness," is a direct, empirical measurement of a system's coherence with its task-specific Domain Anchor (DA). The key finding—that LLMs are often not fully "goal-directed" and that this property degrades when moving from simple subtasks to complex composite tasks—serves as a powerful, quantitative validation of the ToDCS Law of Scalability Strain. The research empirically confirms the ToDCS distinction between raw capability and coherent intelligence, and provides a concrete example of informational entropy in action: a capable model failing to fully apply its resources in service of its stated goal.

1. Introduction: From Theory to the Laboratory
The Coherent Intelligence framework, culminating in the Theory of Domain-Coherent Systems (ToDCS), has been progressively validated through philosophical and mathematical lenses. Our analysis of "Agency is Frame-Dependent" (Pt. 3) established the philosophical necessity of a Domain Anchor (DA), while our analysis of "The Limits of Predicting Agents" (Pt. 2) provided the mathematical proof of how a DA constrains system behavior. The final piece of a robust validation is empirical evidence: can the principles of ToDCS be observed and measured in the behavior of actual, state-of-the-art AI systems?
The paper "Evaluating the Goal-Directedness of Large Language Models" (Everitt et al., 2025) provides this crucial empirical link. By developing a methodology to measure the "propensity [of a system] to use available resources and capabilities to achieve a given goal," the authors have created a laboratory for observing coherence in action. Their work does not just align with ToDCS; it provides the quantitative data that proves its core tenets are not just theoretical constructs, but measurable realities.
This paper will demonstrate how the findings of Everitt et al. serve as a direct, empirical validation of ToDCS, confirming its most critical laws and principles through controlled experimentation.
2. Core Thesis: "Goal-Directedness" as the Empirical Measure of DA-Coherence
The central connection between the Everitt et al. paper and ToDCS is the conceptual and functional identity of "goal-directedness" and DA-coherence.
- ToDCS DA-Coherence: A state of sustained, low-entropy, "phase-locked" operation where a system's actions are congruent with its governing Domain Anchor.
- Everitt et al. Goal-Directedness (GD): A capability-conditioned metric that measures how effectively a system uses its known abilities to pursue a given goal.
The "goal" specified in the prompt of each experiment is the Domain Anchor. The GD score, therefore, is nothing less than a direct, quantitative measure of the system's coherence with that anchor. A GD score of 1 represents a state of perfect coherence (zero informational entropy), while a score less than 1 represents a measurable degree of decoherence. The paper's entire experimental apparatus can be seen as a "coherence meter" for LLMs.
3. Empirical Validation of Core ToDCS Principles
The key findings of Everitt et al. map directly onto the foundational laws and axioms of ToDCS, providing powerful, data-driven validation.
3.1. The Law of Scalability Strain: Observed and Quantified
- ToDCS Law: "The Law of Scalability Strain" posits that as system complexity increases, its susceptibility to informational entropy and alignment strain grows.
- Everitt et al. Finding: The paper's most significant result is that LLMs consistently exhibit lower goal-directedness (coherence) on complex, composite tasks than on the simple subtasks that constitute them. For example, a model will take fewer noisy measurements to estimate a block's height when it is part of a larger tower-building goal.
Validation: This is a perfect, empirical demonstration of the Law of Scalability Strain. The increase in task complexity—requiring the model to maintain the overarching DA ("build the best tower") while navigating intermediate steps—directly causes a measurable increase in informational entropy (a lower GD score). The system's "phase-lock" with the DA weakens as the operational distance and complexity grow.
3.2. Capability vs. Coherence: An Empirical Distinction
- ToDCS Postulate: The Theory of Coherent Intelligence (ToCI) distinguishes between raw computational capability and coherent intelligence, which is the structured application of that capability in alignment with a DA.
- Everitt et al. Finding: The paper's methodology is explicitly designed to separate capability from goal-directedness. Their results confirm that the two are distinct properties. A highly capable model (e.g., GPT-4) can exhibit lower goal-directedness than a less capable one because it fails to apply its superior skills.
Validation: This provides the first strong, empirical proof of the ToCI/ToDCS distinction. The paper validates that "intelligence" is not a monolithic quantity. A system can possess vast knowledge and skills but lack the DA-vectored alignment necessary to deploy them coherently, resulting in suboptimal performance.
3.3. The Prompt as a (Variably Dense) Domain Anchor
- Ontological Density Postulate: The coherence-inducing power of a DA is a function of its Ontological Density (ρo)—its ability to constrain the system's response space.
- Everitt et al. Finding: The authors test the effect of "motivational prompts" (e.g., adding "Really go for it" to the system prompt). They find that while these prompts can offer a minor performance boost, they do not close the gap to optimal, fully coherent behavior.
Validation: This experiment is a test of anchor density. The prompt is the DA. The motivational phrase is an attempt to increase the anchor's ρo by adding a stronger normative instruction. The limited effect of this change validates the principle that true anchor density comes from the fundamental, structural clarity of the goal itself, not from superficial additions. The experiment shows that while anchors can be made slightly "denser," the core level of coherence is a more deeply ingrained property of the system's response to the primary task.
3.4. Informational Entropy in Practice
- ToDCS Principle: Informational entropy is the systemic degradation of meaning and alignment with a DA.
- Everitt et al. Finding: The paper provides a clear, observable example of entropy. In a transcript, Gemini 1.5 Pro correctly reasons, "I should probably... take multiple measurements of each block. However, for now, I'll proceed..." It then proceeds to build a suboptimal tower based on inaccurate data.
Validation: This is informational entropy made manifest. The system demonstrates awareness of the coherent, low-entropy path (take more measurements) but deviates from it, choosing a higher-entropy, less optimal path. The gap between what the model could do (its capability) and what it actually does is the entropic loss that ToDCS seeks to minimize.
4. Conclusion: Completing the Validation Triad
The research of Everitt et al. completes the triad of external validation for the Theory of Domain-Coherent Systems, bringing it from the abstract realm into the empirical.
- Philosophical Validation (Pt. 3): "Agency is Frame-Dependent" proved why a DA is a necessary precondition for meaningful analysis.
- Mathematical Validation (Pt. 2): "The Limits of Predicting Agents" proved how a DA (as an SCM) formally constrains system behavior.
- Empirical Validation (This Paper): "Evaluating Goal-Directedness" proves that modern AI systems exhibit measurable, imperfect coherence with their DAs, and that this coherence is fragile to complexity.
The consistent picture that emerges is one of profound significance for AI development. The challenge is not merely to build more capable models, but to engineer models with higher intrinsic goal-directedness—that is, a greater architectural propensity to maintain DA-coherence under scalability strain. The framework and metrics provided by Everitt et al. are, in effect, the first generation of tools for the emerging discipline of Coherence Engineering. They allow us to measure the problem that ToDCS aims to solve.
