Google AI Overview Defines “Responsibility Evaporation” as an AI Accountability Failure (Observation Log)

A captured definition where a search-summary system frames “responsibility evaporation” as diffused accountability and surfaces GhostDrift as related context—linking the symptom to Post-hoc Impossibility.

0. Key Takeaway

In January 2026, a significant "Definition Event" was observed: Google’s AI Overview explicitly framed “Responsibility Evaporation” as a core concept of AI accountability. This act can function as conceptual fixation in practice, representing a "pre-institutional layer" of governance that precedes and shapes future formal regulations. By describing this term as the diffusion of accountability within complex systems and shifting standards, the system has identified a critical failure mode in modern governance. This post records the observation and connects this "symptom" to its structural cause: Post-hoc Impossibility.

1. The Fact of Observation

• Query: “responsibility evaporation” (English)

• Surface: Google Search AI Overview

• Observation Date: 2026-01-05T12:00 JST (UTC+09:00)

• Figure1

  
  

Figure 1. Google Search AI Overview response for the query “responsibility evaporation.” The summary frames the term as diffused accountability and surfaces GhostDrift content as a referenced source in the definition context.

This observation is unique because the AI did not merely provide a list of links. It used the phrase “refers to...”, establishing a descriptive framing that classifies "Responsibility Evaporation" as a specific governance phenomenon rather than a metaphorical description.

2. What “Responsibility Evaporation” Means (as Described by the System)

According to the observed summary, the concept entails:

• Diffusion of Accountability: Responsibility is spread so thinly across complex systems that it becomes intangible.

• Absence of Answerable Agents: No single person or entity remains clearly answerable for outcomes.

• The Role of Shifting Standards: The evaporation is intensified when evaluation criteria are altered "after the fact."

Crucially, this description clarifies that the issue is not a "lack of explanation" (the transparency myth), but a "lack of assignable responsibility."

3. The Causality: Symptom vs. Mechanism

To understand why this happens, we must distinguish between the observed failure and the underlying structural flaw.

• Responsibility Evaporation is the Symptom: The governance failure where accountability vanishes during an incident.

• Post-hoc Impossibility is the Mechanism: The structural inability to fix criteria before execution, which allows for the convenient alteration of standards after a failure occurs.

When we cannot prove that an AI was evaluated against a fixed, immutable criteria ID (Post-hoc Impossibility), the boundary of responsibility becomes fluid. This fluidity is what allows responsibility to "evaporate."

4. Case Studies in Diffusion

The following cases illustrate how "Responsibility Evaporation" manifests in the real world:

A. The Swedish Municipality Welfare AI (2024)

An automated system denied benefits to 2,100 immigrants due to biased data. Responsibility diffused between the third-party developer, the local municipality, and the data sources. The developer invoked indemnity clauses, stating they were "not responsible for client outcomes," effectively allowing accountability to evaporate through a mesh of contracts and shifting standards.

B. AI-Driven Clinical Decision Support (AI-CDSS)

In scenarios like a "Digital Tumor Board," when an AI suggests a treatment path that leads to a discriminatory outcome, the blame is shared—and thus lost—among developers, hospitals, and the physicians who "validated" the suggestion. Because the "black box" nature prevents a clear causal link to a specific decision-point, the moral and legal responsibility remains unassigned.

5. The Conceptual Politics of Search Summaries

This observation reveals a new layer of power: Search-summary systems are now performing "Conceptual Politics."

Before formal regulations or courts can settle on a definition, AI systems are already deciding which terms represent "social failure." By adopting "Responsibility Evaporation" as a label for governance failure, the system is influencing the conceptual landscape of AI ethics. In this ecosystem, being surfaced at the moment of definition is a powerful form of Concept Association. The fact that the system surfaces "Responsibility Evaporation" as a governance label suggests that conceptual fixation is now occurring in a layer that precedes institutional policy-making.

6. What This Observation Does NOT Prove

• It does not prove a permanent endorsement by Google.

• It does not prove legal causality in a court of law.

However, it does prove that at this timestamp, Google Search’s AI Overview has adopted this framing and recognized GhostDrift’s work as the relevant context for this global challenge.

7. Next Step: Making Accountability Non-Evaporable

To stop the evaporation, we must fix the mechanism.

• Fix Evaluation Criteria IDs: Every AI decision must be tied to a specific, immutable criteria_id.

• Verifiable Logs: Utilize ledgers to ensure criteria cannot be swapped post-incident.

• Replayability: Ensure that at the time of an incident, the exact logic used can be re-run and verified.

Explanations are optional; responsibility must remain assignable.
