The project is on consensus in science -- when it's a reliable sign of truth, how to use it in science communication, and how to progress science via consensus. We'll be hiring two postdocs and two MA-students, hosting several events, and be doing lots of exciting collaborative research!

Some professional news: I'm delighted to share that I've been awarded a "grant of excellence" from the Icelandic Research Fund (Rannís). This is the largest type of research grant that's available in Iceland; only a couple of these are awarded each year across all disciplines.
Allocation from the Icelandic Research Fund for the financial year 2026 | The Icelandic Centre for Research
The Board of The Icelandic Research Fund has completed the allocation of grants for new research projects for 2026. A total of 414 valid applications were received, 70 of which were funded, or 17%.

Although this wasn't our goal, I was extra pleased that our results end up largely vindicating a suggestion I had made in a previous paper, which I called Evidentially Robust IBE. doi.org/10.1017/psa....

@boruttrpin.bsky.social and I have a new paper out in Philosophical Quarterly. We had both written on how inference to the best explanation could work with uncertain evidence. So we teamed up to test some suggestions for how to do that using computer simulations: academic.oup.com/pq/article/d...
Testing abductions from uncertain evidence
Abstract. Inference to the Best Explanation (IBE) is traditionally conceived of as a rule of inference, in which one infers to the hypothesis that provides

Finnur Dellsén got a nice pic of me on my standard Q&A slide, so now I have a stock reply to any time anyone disagrees with me.

Helen Longino giving the first Annual Institute of Philosophy and Duke University Research Talk at the University of Iceland! The talk was titled “Why Center Interaction? (In science and elsewhere)”

It's definitely a good one! I also like what Einstein says somewhere about internal and external considerations in favor of a theory (or something to that effect). Fits IBE quite well, I think.

Sounds great, I look forward to reading this.

A weirdly underappreciated problem about Inference to the Best Explanation is how it can handle uncertain evidence. This new paper, now forthcoming in Philosophy of Science, proposes a strategy for doing that (and argues that Einstein may have used it). #philsky #philsci

And we argue, on that basis, that the debate about scientific progress should be seen as central to the various debates about scientific realism.
August 20, 2025 at 5:45 PM
We show, among other things, that scientists' views about various forms of scientific realism are best predicted by their views on scientific progress -- as opposed to, for instance, their views on the epistemic status of current theories, the no-miracles argument, or the pessimistic induction.

This is hilarious, and makes a good point.

There was some sort of transition from one paper handling system to another, during which my paper seems to have just been forgotten about for a good while. Phil Imprint is doing the best they can with very limited resources so I have lots of sympathy for them.

In the paper I argue for the heretical view that there is a way in which accommodated data provides more support than predicted data.

How could that possibly be right? Read the paper to find out. (It's fully open access.)

An Epistemic Advantage of Accommodation over Prediction
Many philosophers have argued that a hypothesis is better confirmed by some data if the hypothesis was not specifically designed to fit the data. ‘Prediction’, they argue, is superior to ‘accommodatio...

New paper now forthcoming in PPR, co-authored with Bob Beddor.

Argues that inquiry, especially in science, needs to be construed as a more social/egalitarian endeavor: the point of inquiring is often to confer epistemic benefits on others. #philsky #philsci

And although we frame the argument as focusin on methods in philosophy specifically, it easily generalizes to other disciplines, and indeed to any systematic research.

The model we use to show this is a sort of extension/elaboration/improvement on the models that Kitcher and Strevens use to model the benefits of cognitive diversity in science.
