Samuli Reijula

Samuli Reijula (né Pöyhönen)

I am currently (2020-2025) an Academy of Finland research fellow at the University of Helsinki. I work in the theoretical philosophy unit, and my research focuses on two main areas:

  • Institutional epistemology. What are epistemically well-designed social systems like? That is, what are the social, cognitive and institutional conditions of well-functioning scientific research?
  • Evidence-based policy. How are findings from the behavioral sciences used to inform policy design? How should that translation be done?

I am also interested in the epistemology of simulation modeling, computational social science, mathematical explanation, AI, as well as issues related to natural kinds and conceptual change.

As a university lecturer (currently on research leave), I am responsible for undergraduate teaching and supervising in the area of the philosophy of science. I’m also affiliated with TINT, the Centre for Philosophy of Social Science at the University of Helsinki.

Selected publications


  • Here’s a link to a paper I wrote with Petri Ylikoski, where we outline the idea of institutional epistemology. (in Finnish!) (11/2020)
  • I’m on research leave 2020-2025, working on my personal research project funded by the Academy of Finland. The project is called “Modeling the republic of science: Collaborative problem solving and collective rationality in scientific inquiry” (11/2020)
  • Our self-nudging article is getting some attention in media: Yliopisto-lehti, The Decision Lab, NBC Today
  • How can philosophers make use of (simulation) models? Together with Emrah Aydinonat and Petri Ylikoski (Synthese, forthcoming 2020), I argue that e.g. in social epistemology (of science), models should be understood as argumentative devices, and their epistemic status be evaluated accordingly.
  • “Self-nudging and the citizen choice architect” accepted for publication in Behavioural Public Policy. After more than three years on the drawing board, happy to share results from this collaboration with Prof. Ralph Hertwig. (1/2020)

  • Career news. As of August 2019, I will be a university lecturer in theoretical philosophy at the University of Helsinki (6/2019)
  • A new manuscript/preprint on models, simulations, and Robert Brandom’s inferentialism: Making it count. An inferentialist account of computer simulation, here: (6/2019)
  • New town, new university! In September 2018 I’m starting as a university researcher at the University of Tampere.
  • Check out our poster at Cogsci 2018, “Social information can undermine individual performance in exploration-exploitation tasks.” Presented by first author Kyanoush Seyed Yahosseini
  • Looking forward to attending the European Summer School for Scientometrics (ESSS) in Vienna (July 2018).
  • Great news, the Academy of Finland has granted funding for a four-year research project directed by Professor Kristina Rolin. Our project is entitled Social and Cognitive Diversity in Science: An Epistemic Assessment. Looking forward to joining the research team next year!
  • In June 2018, I’m visiting the Centre for Adaptive Rationality (ARC) at the Max Planck Institute for Human Development, Berlin. Great to be back!
  • In April 2018, I received a 12-month grant from the Emil Aaltonen Foundation for research on the social epistemology of science.
  • In May 2018, I will do a brief Midwestern tour in the US. I’ll visit the Knowledge Lab at the University of Chicago, and the Department of Philosophy at Washington University at St. Louis.
  • In Dec 2016, my last name changed from Pöyhönen to Reijula.
