What are "looping effects", actually? Finally, @hsherl.bsky.social offers more clarity for understanding Ian Hacking's funny concept. Recommend: doi.org/10.1080/0951...

I am really happy this collab is out! It's trying to map out the space of possible positions people might have about responsibilities of economists under conditions of reflexive performativity. Looking forward to feedback on this.

One of the best things about academic workshops and conferences is the coffee breaks. Earlier this year, we tried to do only those. It worked unexpectedly well. I wrote up the details if you want to try a different kind of academic workshopping, too! www.jakobortmann.eu/blog/ditch-t...

Happy my manuscript accepted in Philosophy of Science (@philscijournal.bsky.social) is now available! It's carving out a space for speech-act-theory and STS to co-exist, laying out conceptual foundations for further work in philsci. Comments welcome! doi.org/10.1017/psa....

After reading @miguelohn.bsky.social's amazing piece I'm not sure I understand what "intervening in a debate" means!
Screenshot of a paper by Miguel Ohnesorge, with the text highlighted "My goal is not to intervene in these debates. Instead, I will argue that they share a basic but unsubstantiated premise"

Really glad this point has supporters. Frustration on specifically this is what initially drew me to philsci as a profession, and holds me there still. Lack of collective action is rarely inevitable, and the tragedy of the commons is just the wrong game. Dangerous game.

Super happy this paper got accepted for 'Philosophy of Science'! Its an attempt of reconciling speech act theory and STS in a way thats hopefully helpful to philosophers of science and controversies in values in science. #philsci #philsky #HPS @mapsproject.bsky.social philpapers.org/rec/ORTBWI

Incredibly stoked to welcome 12 talented young economists and philosophers this week for our phil-econ-model-lab.org. We're trying a different workshop format: online talks before meetup, then collaborative sessions in person. Will follow up with results, first day was extremely promising.

Our team member, PhD candidate Murat Bakeev, spoke today at an online session of the Phil-Econ-Model-Lab (PEM-L). This workshop, funded by INEM, aims to promote collaboration among early-career scholars, with a particular focus on analyzing the role of value judgments in economic modeling.

New paper "Endogenous Preferences, Environmental Economics, and Welfare" accepted at Politics, Philosophy & Economics. In it, I argue for how we should address endogenous preferences in the welfare assessment of large-scale policy interventions (e.g., a carbon tax). Penultimate version here👇

Here is a quick thought: The new NATO 5% spending goal may not sound like too much, but its actually much more than we would have needed to fix climate change (estimates from 2018) - see chart below.

⏳Deadline approaching! Know any early-career scholars working on philosophy of econ or values in science? Please consider forwarding them our call for proposals at phil-econ-model-lab.org. We are assembling a group of young scholars to collaborate at the cutting-edge of these topics #philsi #econ

My Performative Paternalism paper is out now - looking forward to hear your thoughts, concerns, and whatnot. Its an attempt of cashing out some of the ethical / political issues surrounding performativity of science that seem really important, yet underdeveloped in the current literature.

Delighted to share my first contribution to the @mapsproject.bsky.social project got accepted for publication in the EJPS! It revises epistemic & normative arguments reg. performativity of science (e.g. self-fulfilling prophecies), and reaches an uncomfortable conclusion: performative paternalism!

Today I learned that at some point our department wasn’t allowed to have any books bc books are a fire hazard. Funny enough to ban books at a uni, but I wish they said the same thing about all the paper forms they make us print, fill and sign (and then of course scan again).
