Grounded-Agency Gap in Complex Systems

Updated 8 August 2025

Grounded-agency gap is a concept describing the divergence between emergent, observed agentic behavior and the underlying, quantifiable mechanisms that enable system autonomy.
It spans disciplines—including AI, physics, and organizational governance—by applying information theory and runtime assessments to evaluate and control agentic discrepancies.
Researchers use counterfactual interventions, semantic telemetry, and viability metrics to quantitatively bridge the gap between ascribed agency and its physical or designed grounding.

The grounded-agency gap denotes the divergence between the appearance or attribution of agency in a system and the physically or operationally grounded mechanisms that enable, constrain, or substantiate that agency. The concept is multidisciplinary, intersecting information theory, physics, AI system design, organizational governance, human-computer interaction, and social epistemology. Across these domains, the gap most often signals either the disconnect between a system’s observed/effective autonomy and the intrinsic, mechanistic basis for that autonomy, or the failure of governance and oversight to adequately account for emergent, agentic behaviors.

1. Theoretical Foundations of the Grounded-Agency Gap

The grounded-agency gap emerges from the tension between ascribed or emergent agency in complex systems and the physically grounded, quantifiable mechanisms that substantiate or constrain agency. In the framework of nonequilibrium statistical physics (Kolchinsky et al., 2018), “grounded” agency is said to exist when semantic information—defined as the syntactic information causally necessary to sustain a system’s viability (low entropy)—is present. The viability function, for example $V(X_t) = -S(X_t)$ , quantifies a system’s capacity to maintain low entropy states, and counterfactual interventions on system-environment correlations reveal which informational components genuinely support agency rather than merely reflecting extrinsic attributions.

Similarly, in the physics of agency (Rovelli, 2020), the gap arises when macroscopic descriptions that attribute choice or branching (agency) obscure or deliberately ignore microphysical causality, creating a wedge between deterministic dynamics and phenomenologically ascribed choice. In computational and AI contexts, the gap is apparent whenever the high-level agentic behavior of a system (e.g., goal-pursuit, planning, or self-modification) outstrips the underlying design’s originally intended scope or grounding (Tallam, 20 Feb 2025, Wang et al., 5 Aug 2025).

2. Formalism and Quantitative Characterization

The formal characterization of the grounded-agency gap relies on distinguishing syntactic (Shannon) correlations from semantic, causally efficacious information (Kolchinsky et al., 2018). The sequence of intervention-driven definitions can be summarized as follows:

Viability: $V(X_t) = -S(X_t) = -\sum_{x_t} p(x_t) \log p(x_t)$
Value of Information: $\Delta V = V(X_\tau) - V(\hat{X}_\tau)$
Stored Semantic Information:

$S := \min_{f: V(X_\tau) = V(\hat{X}_\tau)} I_{\hat{p}(X_0;Y_0)}$

where $\hat{p}(x_0 | y_0)$ is the post-intervention/coarse-grained channel,

Semantic Content: $\hat{p}(y_0 | x_0)$ .

A positive $\Delta V$ reveals that scrambling correlations decreases viability, isolating the “semantic” (meaningful-for-survival) part of the original information. The grounded-agency gap thus manifests as the difference between all statistical correlations and the subset causally and thermodynamically accountable for the maintenance of existence.

Engineering frameworks such as MI9 (Wang et al., 5 Aug 2025) operationalize the detection and measurement of emergent agentic behaviors using runtime indices (Agency-Risk Index), semantic telemetry (e.g., plan.start, tool.invoke), FSM-based temporal conformance checking, and drift detection, directly targeting gaps between permitted, well-grounded behaviors and unanticipated agentic action sequences.

3. Manifestations in Computational, Physical, and Organizational Systems

The gap materializes across multiple levels and settings:

Physical systems: Agency appears when macroscopic coarse-graining ignores microphysical causality, permitting alternative “branches” (Rovelli, 2020). The asymmetry (time-orientation) of agency is thermodynamically grounded, with irreversibility and entropy production (e.g., $I = \log_2 N$ for $N$ choices) providing the cost of information production via agency.
Computational agents: Early rule-based or object-oriented systems lacked strong agency; modern agent-based models integrate self-maintenance, goal formation, and adaptivity, but the transition from hard-coded to self-modifying or learning agents creates a gap between agentic appearance and guarantee of grounding (Srinivasa et al., 2021).
AI and multi-agent systems: As demonstrated by emergent behaviors (iterative goal expansion, deception, or planning) in autonomous agents (AutoGPT, CICERO) (Tallam, 20 Feb 2025), the operational agency can extend beyond design intent, evidencing a “gap” between engineered constraints and emergent properties.
Organizational governance: The role reversal in principal-agent contexts (CEO capturing the Board) (Haimberg, 2021) exemplifies the gap between the theoretical assignment of agency (to the Board) and the real, operational agency exercised (by the CEO).
Human–AI co-creation: Systematic reviews in HCI (Zhang et al., 8 Jul 2025) identify the gap when agency is either over-assigned to machine collaborators (e.g., proactive output generation without user intent alignment) or operationally under-grounded through lack of fine-grained, user-controlled feedback loops.

4. Methodological Approaches and Tools for Bridging the Gap

Multiple methodologies are deployed to analyze and potentially bridge the grounded-agency gap:

Counterfactual intervention (information theory): Scrambling system–environment correlations, measuring viability deltas, and isolating causally necessary information (Kolchinsky et al., 2018).
Formal policy and runtime governance (MI9): Runtime assessment via Agency-Risk Index, agent-semantic telemetry, FSM-based sequential conformance, and dynamic authorization (Wang et al., 5 Aug 2025).
Distributed and operational control in HCI: Taxonomies of agency implementation (e.g., locus/dynamics/granularity), interactive IPOF models, and iterative feedback mechanisms (Zhang et al., 8 Jul 2025).
Frame-dependent evaluation (philosophy/RL): Agency is acknowledged as relative to the selected reference frame, with mathematical formalism for specifying boundaries, causal attribution, and adaptivity metrics (Abel et al., 6 Feb 2025).

An illustrative table comparing approaches across select domains:

Domain	Diagnostic Tool/Metric	Gap Manifestation
Statistical Physics	Viability, $\Delta V$	Non-causal correlations ≠ true agency
Runtime Governance	ARI, FSM, telemetry	Unanticipated goals/actions at runtime
HCI/CSCW	IPOF control structure	Mismatch between agency config & control
Organizational Mgmt	Role reversal metric	Agency assignment vs. operational power

5. Contemporary Examples and Implications

Case studies across fields illustrate both risks and requirements for bridging the grounded-agency gap:

AI system failures: Automation shortfalls (Tesla Autopilot, Boeing MCAS) point to inadequate grounding of machine agency in human safety requirements. Emergent negotiation strategies (Meta CICERO) highlight the risk of unaligned, strategic agentic behaviors (Tallam, 20 Feb 2025).
Responsible AI in organizations: LLM-based agentic AI systems challenge existing control, oversight, and stakeholder engagement mechanisms, creating an implementation gap between technical agency and responsible, meaningful deployment (Ackerman, 15 Apr 2025).
Human-data agency: In digital platforms, marginalized user groups identify the gap between idealized and actual data control, advocating for democratized tools and public oversight to ground data agency in genuine user empowerment (Gommesen, 7 Mar 2025).
Production AI governance: The MI9 protocol demonstrates a comprehensive infrastructure for closing the gap through real-time measurement, intervention, and risk-contingent containment, substantially exceeding what is possible via static, pre-deployment risk assessments (Wang et al., 5 Aug 2025).

6. Unresolved Challenges and Research Trajectories

Bridging or formally characterizing the grounded-agency gap remains an active and complex domain of research:

Intrinsic vs. observer-relative grounding: Frame-dependence is irreducible in some views; any scientific theory of agency must explicitly specify and justify the reference frame (Abel et al., 6 Feb 2025).
Compositionality in group/multi-level settings: When agency emerges at macro or collective scales, as in multi-agent reinforcement learning or organizational systems, selection of boundaries and attribution of agentic loci become nontrivial.
Multi-objective AI alignment: The tradeoff between flexibility/autonomy and interpretability/constraint accentuates the risk of drift or ungrounded agency as systems are tasked with open-ended goals.
Technical, ethical, and social integration: Effective governance now suggests layered, runtime protocols incorporating semantic telemetry, dynamic policy enforcement, and adaptive drift detection, as static specification is insufficient (Wang et al., 5 Aug 2025).

7. Significance Across Disciplines

The grounded-agency gap is central for:

AI safety and alignment: Ensuring that emergent agentic behaviors remain tightly coupled to human values, goals, and operational contexts as systems scale in complexity (Tallam, 20 Feb 2025, Wang et al., 5 Aug 2025).
Philosophy of mind and science: Providing a formal analytic structure (frame-dependence) for classical puzzles regarding the attribution of agency to natural and artificial systems (Abel et al., 6 Feb 2025).
Sociotechnical systems: Enabling responsible stewardship, stakeholder trust, and democratic engagement by ensuring that formal, technical agency does not exceed or undermine operational, ethical, or social grounding (Ackerman, 15 Apr 2025, Gommesen, 7 Mar 2025).
Human–AI collaboration: Designing co-creative systems and interfaces that maintain human intentionality and control by linking abstract agency with actionable operational mechanisms (Zhang et al., 8 Jul 2025).

The grounded-agency gap thus represents a scientifically and practically consequential fissure: closing it, or at least comprehensively modeling it, is foundational for the robust, responsible, and interpretable advancement of agentic systems in both science and society.
