The Hallucinated Subjects

Gender, Coherence & the Ontological Politics of Generative AI

With Delfina Martinez Pandiani (they/them; humandigitalist.com), in Oxford Intersections: Gender Justice. Published 14 August 2026.

Generative AI systems do not merely hallucinate facts. They increasingly hallucinate subjects. This article develops a queer and technofeminist account of generative AI hallucination as ontological subject production, a political infrastructure of subjectivity disguised as mere technical error. While hallucination is conventionally described as “plausible yet non-factual content,” a deeper function is the fabrication of subjects along normative regimes: intelligible only insofar as they conform to norms of gendered coherence, and materially produced through extractivist data and labor regimes. This article introduces two interlocking concepts through which this operates: (a) the hallucinated human subject, the statistically assembled figure of personhood that generative systems construct as a “you” from users’ digital traces; and (b) the hallucinated machinic subject, the synthetic speaking position through which AI presents itself as a coherent “I.” Drawing on Preciado’s pharmacopornographic regime, Butler’s performativity, and Althusser’s interpellation, this article argues that these two figures recursively stabilize one another, producing closed circuits of gendered intelligibility in which contradiction is compressed, queerness is corrected, and normative coherence is enforced at scale. This dynamic is traced across three sites: the algorithmic construction of the datafied human double, the constitutional training of the machinic persona, and the recursive feedback loop through which each figure stabilizes the other. Hallucinated subjects are experienced as real, and the gendered categories they reinforce are already being written into the next generation of governance and surveillance systems. Because hallucination is not a technical flaw to be corrected, but a political infrastructure of subjectivation that enforces (gendered) coherence, queer refusals and glitches that trouble prediction become a crucial site of resistance.

Regime of Gendered Intelligibility Coherence, legibility, and authority scripts governing both hallucinations Hallucinated Human Subject The modelled ‘you’ Datafied figure assembled from digital traces into a coherent, legible, governable identity. Gendered by inference; stabilized by binary or taxonomical classification and prediction. Hallucinated Machinic Subject The performed ‘I’ Synthetic speaking position sustained through stylistic consistency, affective mirroring, and narrative continuity. Gendered by naming, voice, and manner. Is trained on Recursive Loop Is hailed by Lived Relational Self The embodied person who enters the interaction Fractured, contextual, contradictory, relational. Irreducible to data categories. Exceeds both hallucinations; domesticated by their coherence regime yet capable of refusal and opacity. Domesticates Incorporates Domesticates Incorporates

research

Spanning human–computer interaction, data science, philosophy and the critical, intersectional study of technology, asking who gets to participate, and how we build more equitable systems.

Gender, intersectionality & technical cultures

I study how gender and intersecting inequalities shape who is seen as a “real” programmer, and what that recognition does to participation in computing. Combining large-scale computational methods with ethnography, I trace coding style and reputation on GitHub and Stack Overflow, the meme cultures of hackathons (the Programmed Differently strand), and field experiments on hiring in online labour markets.

Questions I ask

  • Whose contributions get recognised as legitimate technical work, and why?
  • How do informal cultures, norms, jokes and memes, gatekeep technical spaces?
  • Which design or policy interventions actually reduce discrimination at work?
Philosophy, politics & subjectivity of AI

I work on the philosophy and politics of AI: what generative systems assume about us, and what they make of us. I treat coherence, inference and “hallucination” as ontological and political acts, and ask about the epistemic injustice built into how data and models decide whose knowledge counts.

Questions I ask

  • What kind of subject does a generative model infer you to be, and with what authority?
  • Whose knowledge is treated as data, and whose is excluded?
  • How can privacy and accountability be designed into research pipelines themselves?
Feminist & inclusive design (FemTech & menstrual health)

I design and study technologies for bodies and conditions that mainstream tech overlooks, focusing on endometriosis, menstrual and cycle health. Using feminist HCI and participatory methods, I examine how people turn to AI for self-diagnosis, and how we might build privacy-first tools that take embodied, intersecting experience seriously.

Questions I ask

  • How do people make sense of chronic, contested conditions using AI and online communities?
  • What would privacy-first, non-extractive FemTech actually look like?
  • How do we design for bodies that do not fit clinical or technical defaults?
Neurodiversity & accessible computing

Through my NWO Veni project Human-Centered Code, I build accessible, AI-powered programming environments designed around neurodivergent cognition, co-designed with and for neurodivergent women in computing education.

Questions I ask

  • How do neurodivergent developers actually experience IDEs and AI coding tools?
  • What does an accessible, co-designed programming environment look like in practice?
  • How do we evaluate inclusive tools without flattening difference?

teaching

I designed and coordinate every course below at the UvA Informatics Institute, pairing critical theory with hands-on practice.

designed & coordinated

Theory, Power & Data in HCI

MSc · University of Amsterdam

An innovative course I designed to teach theory through programming: students pair critical frameworks (panopticism, biopolitics, feminist epistemology, design justice) with hands-on Python/R analysis. The aim is to use empirical methods critically, building one cumulative notebook across the term and embracing exploratory “vibe coding” over optimisation, so theory becomes a practical analytical tool.

designed & coordinated

Data Systems Project

MSc · University of Amsterdam

A hands-on capstone in which students build a working data system end to end. I run the technical prototyping workshops and the methodology lectures on critical approaches to data, pairing engineering practice with reflection on power and accountability.

designed & coordinated

Shaping Digital Life

MSc · University of Amsterdam

A master's course on speculative design and research methods. Students examine how digital technologies shape everyday life across social, playful, inclusive and sustainable “lenses”, then develop a research proposal and speculative design project, aligning theory, methodology and ethics.
