Sheila Sen Jasanoff (born 1944) is a foundational figure in Science and Technology Studies (STS), widely recognized as one of its most influential architects and theorists. She is the Pforzheimer Professor of Science, Technology, and Society at Harvard Kennedy School, where she founded and directs the Program on Science, Technology and Society. Her work bridges law, political science, sociology of knowledge, and STS, with a consistent focus on how scientific knowledge and social order are mutually constitutive.

Key Contributions and Concepts

• Co-production: Jasanoff’s most enduring theoretical contribution. It describes the simultaneous processes through which modern societies form their epistemic (knowledge-based) and normative (value-based) understandings of the world. Scientific knowledge and social institutions, identities, discourses, and power relations evolve together rather than one determining the other. This idiom, systematically elaborated in States of Knowledge: The Co-Production of Science and Social Order (2004), has become central to STS.
• Sociotechnical Imaginaries: Collectively held, institutionally stabilized visions of desirable futures animated by science and technology. These imaginaries shape how societies understand progress, risk, citizenship, and governance. Developed with Sang-Hyun Kim in Dreamscapes of Modernity (2015), the concept emphasizes the cultural and political embedding of technoscientific projects.
• Comparative and Institutional Analysis: Jasanoff is known for rigorous cross-national comparisons (especially US vs. Europe) on topics such as biotechnology regulation (Designs on Nature, 2005), risk governance, science advising (The Fifth Branch, 1990), and environmental decision-making. Her legal training informs analyses of how expertise operates in courts, policy, and regulation.

Career and Impact

Trained in law, linguistics, and with a background in the sciences, Jasanoff has played a decisive role in institutionalizing STS. She founded the STS Department at Cornell and later the Harvard program. She received the 2022 Holberg Prize for her pioneering contributions. Her scholarship is characterized by interpretive social science, constructivism, and a strong emphasis on democratic governance of science and technology.

Relevance to Socioplastics (Lloveras)

In the context of Anto Lloveras’s project, Jasanoff’s framework offers productive parallels and points of divergence:

• Field and Knowledge Infrastructure: Both engage deeply with how knowledge systems are built and sustained. While Bourdieu provides Lloveras with a relational sociology of fields and distinction, Jasanoff supplies a richer account of co-production between epistemic practices and social/institutional orders. Socioplastics can be read as a deliberate, large-scale experiment in co-producing a transdisciplinary epistemic field through its own infrastructure (numbered nodes, Scalar Grammar, Mesh Engine, Soft Ontology, bibliographic machine).
• Construction vs. Critique: Jasanoff’s work often analyzes existing sociotechnical orders. Lloveras radicalizes this into active field architecture — building an autonomous, self-elaborating epistemic morphology at massive scale (4000+ nodes). Concepts like sociotechnical imaginaries resonate with Lloveras’s vision of the numbered field as a public cognitive environment and “school.”
• Latency, Legibility, and Governance: Jasanoff’s attention to how knowledge becomes authoritative aligns with Lloveras’s ideas of epistemic latency, grammatical thresholds, synthetic legibility, and the Mesh Engine’s transition from archive to generative force.

Jasanoff represents a sophisticated, politically attuned strand of STS that emphasizes responsibility, democracy, and the entanglement of knowledge and power—resources that a project like Socioplastics can metabolize while pushing further into constructive, post-institutional field-building. Her oeuvre remains essential for anyone thinking seriously about the architecture of knowledge systems in contemporary conditions.
