Agnotology Lab — Structural Analysis of Informational Injustice and Counter-Design

What Is Silence-Structuring? — The Architecture of Pluralistic Ignorance

This essay refines the three-stage silence-structuring model proposed in Article #1 by mapping it onto pluralistic ignorance theory and adjacent constructs (conformity pressure, spiral of silence, groupthink). The aim is to clarify why the mechanism of structuring deserves to be distinguished from mere conformity.

The Reproduction of Authority and Ignorance — The Structure of 'No Need to Know'

Starting from Nadainada's 'Authority and Power,' this analysis examines the mechanisms by which authority instills the notion of 'no need to know' and structurally reproduces ignorance. Through case studies in education, healthcare, and judiciary, it reveals the structure of epistemic submission.

Motivated Ignorance — The Cognitive Structure of 'Not Wanting to Know'

Analyzing the mechanism by which individuals voluntarily choose to 'remain ignorant' rather than being forced into ignorance from external sources, from a cognitive science perspective. Examining how the 'illusion of knowledge' demonstrated by Sloman & Fernbach's 'The Knowledge Illusion' and motivated reasoning form the individual-level foundation of structural ignorance.

The Production Mechanism of Taboos — Who Decides What 'Must Not Be Said'

A structural analysis of the questions raised by Akira Tachibana's 'Things That Must Not Be Said'—examining the mechanisms by which discussing genetics, intelligence, and appearance becomes 'forbidden to speak of' through the lens of agnotology. Taboos do not emerge naturally but are produced and maintained under specific social conditions.

Literature Map of Agnotology in the Japanese-speaking World 2022–2026 — Tracing the Birth of a Discipline

From the 2022 special issue of Journal of History of Science (Vol. 61) to the 2025 publication of 'Invitation to Agnotology,' this article organizes the development of agnotology research in the Japanese-speaking world as a literature map. We track researcher networks, major publications, and academic presentations chronologically to visualize the current state of this emerging academic field.

Japan's Structural Reproduction of Climate Skepticism (How Doubt Circulates)

Despite an established scientific consensus, climate change skepticism continues to take root in Japan's media and public discourse. This phenomenon is not a product of individual ignorance but of structural mechanisms that circulate doubt. This article applies the agnotological framework to analyze the circuits through which skepticism is reproduced in Japan.

The Statistical Absence of Femicide (The Structure of Deaths That Cannot Be Counted)

The category 'femicide' does not exist in Japan's official statistics. The phenomenon of women being killed on the basis of gender-based discrimination is occurring, yet no framework exists to measure it. This article uses an agnotological perspective to analyze how the absence of statistics renders a social problem effectively nonexistent.

The Monthly Labour Statistics Scandal and the Reproduction of State Ignorance — When the Numbers 'Did Not Exist'

The systematic falsification of the Ministry of Health, Labour and Welfare's 'Monthly Labour Survey' revealed in 2018 was not a mere survey error. The core of the problem lies in the 'structure of ignorance' that allowed the misconduct to go undetected for nearly twenty years. This article analyzes the mechanisms through which strategic ignorance was produced around national statistics.

Selective Description in Educational Curricula and the Filtering of Knowledge

What is taught determines what remains unknown. The selection, exclusion, and reduction of content in Japan's educational curriculum is a product of political and social dynamics. This article analyzes the mechanisms through which ignorance is produced via schooling, using the framework of agnotology.

"I Have No Recollection" — The Institutionalization Mechanism of Political Memory Denial

In Japanese politics, the response 'I have no recollection of that' recurs across parliamentary testimony and records-disclosure proceedings. This is not a matter of individual memory loss; it is a practice of institutionalized ignorance deployed to evade accountability. This essay analyzes the denial of political memory through the framework of agnotology, revealing its mechanisms and functions.

Information Literacy as Counter-Design: Curriculum Principles Centered on Epistemic Justice

Conventional media literacy education is biased toward individual responsibility and does not address the production structure of ignorance. This essay proposes a counter-design theory built on three layers — analysis of the production structure, critical reading by recipients, and design of collective intervention — with epistemic justice at its core, and derives five curriculum design principles.

Counter-Design Practices in Japan — A Structural Analysis of Domestic Attempts to Implement Epistemic Justice

This essay examines Counter-Design theory through domestic Japanese cases. Using five criteria (implementation of epistemic justice, collective intervention, analyzability of structure, continuous operation, transferability), it selects five cases and analyzes their target structures of ignorance production, forms of counter-design intervention, and achievements and limits.

A Methodology for International Comparison of Counter-Design — A Framework for Comparing Four Lineages that Implement Epistemic Justice

This note presents a methodology for internationally comparing counter-design practices that implement epistemic justice. It sketches a comparative framework across five axes (thought, subject, method, evaluation, funding) for four lineages — Nordic co-design, U.S. Design Justice, U.K. civic tech, and Latin American popular education — and makes explicit ISVD's position and its chosen combination of lineages.

The Archaeology of Silence — Five Methods for Excavating What Was Never Debated

A methodology for systematically excavating problems that were never debated. Connecting Foucault's archaeology, Trouillot's four-stage silencing, and Fricker's hermeneutical injustice, this essay organizes silence into four layers (Absence / Concealment / Distortion / Delegitimization) and matches them with five methods of retroactive detection (statistical absence / archival inversion / testimonial reconstitution / comparison / temporal shift).

Cross-Axis Analysis of 22 Notes / Structural Patterns in Ignorance Production

A cross-axis reading of the 22 research notes (coding: 7 axes) accumulated in the Agnotology Lab. Top mechanisms: attention-control / silence-structuring / doubt-manufacturing. Actors: institution dominates with 15 notes. powerDirection: top-down accounts for 18 notes. The next research agenda emerges from both the strong biases and the blank spots.

The New Ignorance Produced by Algorithms — Filter Bubbles and Echo Chambers

Recommendation algorithms, search engine optimization, and social media feed design automatically determine what users do not see. This structural ignorance, which arises not from intentional design but as a consequence of optimization, is analyzed as a compound mechanism of attention control and complexity weaponization.

Why Are the Voices of Persons with Disabilities Not Heard? — The Japanese Structure of Testimonial Injustice

This case study analyzes the mechanism by which the voices of persons with disabilities are systematically discounted as 'subjective' or 'emotional,' drawing on the intersection of Fricker's testimonial injustice theory and agnotology. Using Arai Yūki's Shōgaisha Sabetsu o Toinaosu as a primary reference, it illuminates the structure of epistemic exclusion within Japan's welfare system.

'Kūki' and Sontaku — The Japanese Form of Pluralistic Ignorance

This case study integrates the 'rule by atmosphere' (kūki) analyzed by Yamamoto Shichihei in A Study of 'Atmosphere' and the concept of 'sontaku' (anticipatory compliance), which gained political attention from 2017, within the theoretical framework of pluralistic ignorance. It illuminates the mechanism that structures the state of 'knowing but not speaking' by radically raising the cost of dissent.

Why Unreported Issues Are Treated as 'Nonexistent' — Media Agenda-Setting and Invisibilization in Japan

Why do 'unreported issues' disappear from social perception? This case study analyzes the 'non-reporting structure' built into Japanese media by the press club system, sponsor pressure, and audience metrics — through the lens of agnotology. It illuminates how agenda-setting theory and framing effects erase unreported problems by rendering them as 'nonexistent' in social cognition.

Okinawa and Structural Ignorance — The Politics of Mainland Japan's 'Not Knowing'

Starting from Nishiyama Hideshi's (2023) analysis of 'the structural ignorance of mainland Japanese toward Okinawa' in Gendai Shisō, this case study examines how 'not knowing' about the base issue functions politically. The compound mechanism of attention control and epistemic exclusion is theorized.

Poverty and Epistemic Exclusion — The Structure of 'Being Unable Even to Know'

The loss of 'three bonds' (san-en) depicted in Suzuki Daisuke's Saihinkon Joshi is inseparable from the severance of access to information. This case study analyzes the spiral in which poverty enforces ignorance and ignorance reproduces poverty as a compound mechanism of epistemic exclusion and complexity weaponization.

Why Predatory Business Endures — Structural Analysis of Converting Information Asymmetry into Profit

Real estate, insurance, telecommunications, financial products — this case study analyzes how predatory business models exploit the information-poor through the agnotological concept of 'complexity weaponization.' Why can businesses intentionally complicate information to convert consumers' 'not knowing' into profit? An anatomy of the cross-industry exploitation model that persists across sectors.

The Doubt Manufacturing Industry — The Sixty-Year War of Tobacco and Climate

This case study analyzes sixty years of history in which the tobacco and fossil fuel industries systematically 'manufactured doubt' against scientific consensus. From the fact that the same group of scientists and the same strategic patterns were repeatedly employed, 'doubt manufacturing' is theorized as a foundational mechanism of ignorance production.

From 'Merchants of Doubt' to 'Captors of Regulation' — Reading Big AI's Regulatory Capture through 27 Mechanisms

Birhane et al. (2026, FAccT'26) present a taxonomy of 5 categories and 27 mechanisms of Big AI's regulatory capture. This synthesis integrates that taxonomy into ISVD Agnotology Lab's 7-axis coding framework, tracing how the doubt-manufacturing tactics perfected by tobacco, oil, and pharmaceutical industries have transferred to the AI sector. Drawing on empirical data of 100 articles, 249 cases, and 11 dominant narratives, the article reads the contemporary form of the infrastructure of ignorance production.
