# Alignment target underspecification compounds across three layers: preferences, objectives, and measurement
The alignment problem faces irreducible underspecification at three distinct layers, each with its own mathematical or computational impossibility:
**Layer 1: Preference Aggregation**
Arrow's Impossibility Theorem shows we cannot aggregate diverse human preferences into a single coherent objective without violating at least one fairness condition (Pareto Efficiency, Independence of Irrelevant Alternatives, or Non-Dictatorship). This is not a limitation of current voting systems—it's a mathematical constraint on what preference aggregation functions can exist.
**Layer 2: Objective Specification**
Hidden complexity in human values makes encoding goals in code intractable. Our goals contain implicit structure comparable to visual perception—we cannot fully specify what we want because much of our value system is tacit, context-dependent, and discovered through interaction rather than introspection. This creates a specification gap that no amount of better language design can close.
**Layer 3: Intelligence Measurement**
Oswald, Ferguson, and Bringsjord (2025) prove that Arrow's Impossibility Theorem applies to machine intelligence measures themselves. No agent-environment-based MIM can simultaneously satisfy Pareto Efficiency, Independence of Irrelevant Alternatives, and Non-Oligarchy. This means we cannot even define what "intelligence" means in a way that satisfies basic fairness criteria.
## Why These Are Three Distinct Problems
These are not three descriptions of the same underlying issue—they are three independent impossibilities that compound:
- **Even if we could measure intelligence fairly** (we cannot), we still could not specify objectives precisely (we cannot)
- **Even if we could specify objectives precisely** (we cannot), we still could not aggregate preferences fairly (we cannot)
- **Even if we could aggregate preferences fairly** (we cannot), we still would not have solved the measurement problem
Each layer adds its own irreducible underspecification. The measurement impossibility means we cannot even define the capability we're trying to align, independent of the preference aggregation and specification problems.
## Implications for Alignment Strategy
This three-layer structure suggests that alignment cannot be solved by:
- **Better benchmarks** — The measurement layer is fundamentally constrained by Arrow's theorem
- **Better value learning** — The preference aggregation layer is fundamentally constrained by Arrow's theorem
- **Better specification languages** — The objective encoding layer is fundamentally constrained by hidden complexity
The convergence of impossibility results across four independent intellectual traditions (social choice theory, complexity theory, multi-objective optimization, intelligence measurement) points toward a structural reality: alignment as traditionally conceived—converging on a single coherent objective that satisfies fairness criteria—may be asking for something mathematics cannot provide.
## Alternative Framing: Alignment as Coordination
If alignment-as-convergence is impossible, the viable path may be alignment-as-coordination: building systems that navigate irreducible disagreement rather than eliminating it. This requires different infrastructure:
- Collective intelligence mechanisms that aggregate without requiring consensus
- Pluralistic governance structures that accommodate irreducibly diverse values
- Continuous value negotiation rather than fixed objective functions
- Mechanisms for handling persistent, principled disagreement
This shifts the problem from "how do we specify the right objective" to "how do we build systems that remain safe and beneficial while operating under irreducible value pluralism."

# Arrow's Impossibility Theorem applies to machine intelligence measurement, making fair benchmarks mathematically impossible
Arrow's Impossibility Theorem, traditionally applied to social choice and preference aggregation, has been formally proven to apply to machine intelligence measures (MIMs) in agent-environment frameworks. The proof demonstrates that no agent-environment-based MIM can simultaneously satisfy analogs of Arrow's three fairness conditions:
1. **Pareto Efficiency** — if all agents prefer one measure over another, the aggregated measure must reflect this
2. **Independence of Irrelevant Alternatives** — the ranking of two measures should not depend on the presence of a third
3. **Non-Oligarchy** — no subset of agents should have dictatorial power over the measure
**Affected measures include:**
- Legg-Hutter Intelligence
- Chollet's Intelligence Measure (ARC)
- A large class of agent-environment-based MIMs
The result was published at AGI 2025 (Conference on Artificial General Intelligence) in Springer LNCS vol. 16058, indicating peer-reviewed formal verification by established AI formalists (Bringsjord is a well-known AI formalist at RPI).
## Why this matters for alignment
This extends the impossibility problem from **alignment targets** (what values to optimize for) to **measurement infrastructure** (how to define what intelligence even means). The problem is not merely that we struggle to specify values—it's that the measurement framework itself inherits the impossibility.
If we cannot measure intelligence fairly across diverse agent-environment frameworks, then:
- The alignment target becomes even more underspecified than previously understood
- You cannot align to a benchmark if the benchmark itself violates fairness conditions
- Any choice of MIM necessarily privileges some agents' or environments' conception of intelligence over others
## Structural significance
This represents a fourth independent intellectual tradition confirming convergent impossibility:
1. Social choice theory (Arrow's original theorem on preference aggregation)
2. Complexity theory (computational intractability results)
3. Multi-objective optimization (Pareto frontier tradeoffs)
4. Intelligence measurement (this result)
The convergence across independent mathematical frameworks suggests structural rather than contingent barriers to universal intelligence measurement.
## Limitations and open questions
The full paper was not accessible during extraction (paywalled). Remaining unknowns include:
- The specific proof technique employed
- Whether constructive workarounds exist (analogous to those proposed for alignment impossibility)
- Whether the impossibility applies only to agent-environment frameworks or to broader MIM classes

# Arrow's Impossibility Theorem applies to machine intelligence measurement, making fair universal intelligence metrics mathematically impossible
Oswald, Ferguson, and Bringsjord (2025) prove that Arrow's Impossibility Theorem—originally about aggregating preferences into a single social choice—applies equally to measuring machine intelligence in agent-environment frameworks. The proof demonstrates that no machine intelligence measure (MIM) can simultaneously satisfy analogs of Arrow's three fairness conditions:
1. **Pareto Efficiency** — If all environments prefer agent A over agent B, the measure must rank A higher
2. **Independence of Irrelevant Alternatives** — The ranking of A vs B cannot depend on the presence of a third agent C
3. **Non-Oligarchy** — No subset of environments can dictate the overall ranking
**Affected measures include:**
- Legg-Hutter Intelligence (the dominant formal definition in the literature)
- Chollet's Intelligence Measure (the theoretical basis for the ARC benchmark)
- "A large class of MIMs" in agent-environment frameworks (per abstract)
The impossibility is structural, not empirical—it's a mathematical constraint on what kinds of measurement functions can exist, not a limitation of current implementations or a gap that better engineering can close.
## Why This Matters for Alignment
This result creates a meta-level underspecification problem: if we cannot measure intelligence fairly, the alignment target becomes even more underspecified than previously understood. You cannot align an AI system to a benchmark if the benchmark itself violates basic fairness conditions. The problem is not just that we disagree about what intelligence means (preference aggregation problem), but that no measurement function can exist that satisfies fairness criteria simultaneously.
This extends the impossibility pattern from social choice theory (Arrow's original theorem) to the measurement layer itself—independent of preference aggregation or objective specification problems.

**Publication venue:** AGI 2025—the premier conference focused on general intelligence research. Bringsjord is a well-known AI formalist at Rensselaer Polytechnic Institute with extensive work on formal verification and AI safety.
**Scope:** The abstract confirms the result applies to "agent-environment-based MIMs" and explicitly names Legg-Hutter and Chollet measures as affected cases.
## Limitations and Open Questions
Full paper not accessed (paywalled). Cannot verify:
- Exact proof technique or whether it uses Arrow's original machinery directly or requires adaptation
- Whether constructive workarounds exist (analogous to how some alignment impossibilities have practical approximations or escape clauses)
- Precise scope conditions (what classes of MIMs, if any, escape the impossibility)
- Whether the impossibility is as severe for measurement as it is for preference aggregation, or whether measurement allows partial satisfactions

# Convergent impossibility across four independent traditions strengthens the structural argument against universal solutions
When multiple independent mathematical traditions converge on impossibility results for the same class of problems, this suggests structural rather than contingent barriers. Four distinct intellectual traditions have now produced formal impossibility theorems relevant to AI alignment and coordination:
1. **Social choice theory**: Arrow's Impossibility Theorem (1951) — no voting system can satisfy Pareto Efficiency, Independence of Irrelevant Alternatives, and Non-Oligarchy simultaneously when aggregating preferences
2. **Complexity theory**: computational intractability results (NP-completeness, undecidability) for certain optimization problems
3. **Multi-objective optimization**: fundamental Pareto frontier tradeoffs between competing objectives
4. **Intelligence measurement**: Oswald, Ferguson & Bringsjord (2025) — Arrow's conditions cannot be satisfied by agent-environment-based machine intelligence measures
## Why convergence matters
These traditions developed independently, using different mathematical frameworks and problem formulations, yet arrived at structurally similar impossibility results. This pattern suggests the barriers are fundamental to the problem structure rather than artifacts of particular formulations or limitations of current techniques.
The convergence is particularly significant because:
- Each tradition uses distinct mathematical machinery (voting theory, computational complexity, optimization theory, agent-environment frameworks)
- Each was developed to address different domains (social choice, computation, resource allocation, capability measurement)
- Yet all arrive at the same structural conclusion: certain classes of problems admit no universal solutions
## Implications for AI alignment
The convergence strengthens arguments that:
- **Universal alignment solutions may be mathematically impossible**, not merely difficult or currently unknown
- **Pluralistic approaches that accommodate irreducible diversity may be necessary rather than optional** — if you cannot aggregate preferences fairly, you cannot converge on a single aligned state
- **Measurement infrastructure itself inherits the impossibility**, not just preference aggregation — you cannot even define what success looks like in a universally fair way
- **The search for "the" aligned AI or "the" correct intelligence measure may be pursuing a mathematical impossibility** — the problem structure forbids it

The impossibility extends beyond preference aggregation to measurement infrastructure itself. Oswald, Ferguson & Bringsjord (2025) prove that no agent-environment-based machine intelligence measure can simultaneously satisfy Arrow's fairness conditions (Pareto Efficiency, Independence of Irrelevant Alternatives, Non-Oligarchy). This means even defining what intelligence means in a fair way is mathematically impossible, making the alignment target even more underspecified than previously understood. You cannot align to a benchmark if the benchmark itself violates fairness conditions. This strengthens the case for pluralistic approaches: if measurement itself cannot be universal, then alignment strategies must accommodate the irreducible diversity in how intelligence is defined and evaluated.

Anthropic's RSP rollback demonstrates the opposite pattern in practice: the company scaled capability while weakening its pre-commitment to adequate safety measures. The original RSP required guaranteeing safety measures were adequate *before* training new systems. The rollback removes this forcing function, allowing capability development to proceed with safety work repositioned as aspirational ('we hope to create a forcing function') rather than mandatory. This provides empirical evidence that even safety-focused organizations prioritize capability scaling over alignment-first development when competitive pressure intensifies, suggesting the claim may be normatively correct but descriptively violated by actual frontier labs under market conditions.

Oswald et al.'s proof that Arrow's Impossibility Theorem applies to machine intelligence measurement creates a deeper problem: if we cannot even measure intelligence fairly (satisfying Pareto Efficiency, Independence of Irrelevant Alternatives, and Non-Oligarchy simultaneously), then building alignment mechanisms requires solving an impossibility before we can even define the target. The measurement infrastructure itself is mathematically constrained, not just the alignment strategy. This affects foundational benchmarks like Legg-Hutter Intelligence and Chollet's ARC. The implication is that 'safe development' cannot be defined in a universally fair way—different stakeholders will necessarily disagree on what safety measurements mean, making the premise of the claim (that we can build mechanisms before scaling) more problematic than previously understood.
(extend) Oswald, Ferguson & Bringsjord (2025) prove Arrow's Impossibility Theorem applies not just to preference aggregation (the original alignment impossibility) but to intelligence measurement itself. No agent-environment-based machine intelligence measure can simultaneously satisfy Pareto Efficiency, Independence of Irrelevant Alternatives, and Non-Oligarchy. This affects Legg-Hutter Intelligence, Chollet's ARC measure, and 'a large class of MIMs.' The impossibility extends from 'we cannot aggregate preferences fairly' to 'we cannot even measure intelligence fairly'—a meta-level underspecification where the alignment target itself violates fairness conditions. This strengthens the case for pre-scaling alignment work: if the measurement layer is fundamentally constrained, alignment mechanisms must be built before we scale to systems where measurement failures become catastrophic.

Bostrom's proposed solution is indirect normativity -- rather than specifying a concrete value, specify a process for deriving a value and let the superintelligence carry out that process. The most developed version is Yudkowsky's coherent extrapolated volition (CEV): implement what humanity would wish "if we knew more, thought faster, were more the people we wished we were." This approach offloads the cognitive work of value specification to the superintelligence itself. The LivingIP approach of [[the alignment problem dissolves when human values are continuously woven into the system rather than specified in advance]] is structurally aligned with indirect normativity -- both recognize that static specification is doomed.

The intractability extends to measurement infrastructure itself. Oswald, Ferguson & Bringsjord (2025) prove that even defining what intelligence means in agent-environment frameworks cannot satisfy Arrow's fairness conditions simultaneously. This means the problem is not just specifying values (what to optimize for) but also specifying intelligence (what capability even means). Both the target and the measurement framework inherit fundamental impossibility constraints. If values are intractable to specify because they contain hidden complexity, and intelligence measures are mathematically impossible to define fairly, then the combined problem—aligning AI to human values while measuring whether alignment succeeded—faces compounded intractability.
