Is it possible to change belief in free will with a quick manipulation?

Answer seems to be: There is only an effect if you measure free will belief *immediately* after the manipulation… no effect if you measure free will belief even a few minutes later

The journal Cognition – arguably the top journal in cognitive science – has published *ninety-nine* experimental philosophy papers

Clearly, experimental philosophy is now very well integrated into the broader field of cognitive science

[Experimental Philosophy Journal @xphijournal]

Very happy to invite you to the third online talk in our series. Next Thursday, 11th June, 4pm CET, Pascale Willemsen and Lucien Baumgartner. Everyone welcome!

Representing possible alternatives lies at the heart of moral judgment. As LLMs become embedded in our reasoning processes, they change the set of alternatives we bring to mind.

Our #CogSci2026 paper shows that AI might be making us judge people harsher⚖️

Latest papers: Mara Floris, Cristina Ganz & Annamaria Grisorio analyse how epistemic and affective injustices intersect in clinical encounters, showing how power asymmetries sustain delay in Endometriosis diagnosis https://t.co/tfi6jOJDfr

How do people decide whether it’s wrong to harm a pig? A chimp? A baby?

In the West, these judgments are based more on *experience* (being able to feel) than on *agency* (being able to think and act)

Study from @bxjaeger finds that same pattern across other cultures

[Experimental Philosophy @xphilosopher]

The *majority* of philosophy papers now cite at least some empirical data. Papers that do purely a priori philosophy are in a minority

What is the folk concept of FAKE NEWS? M. Kürthy & I ran some studies (N=1200), showing falsity and source deception (posturing as a reliable newspaper) increase fake-news classifications. Conservatism also plays a role. Preprint: https://t.co/6IqSw0bh4t

Beautiful experimental philosophy paper on what people ordinarily mean when they say that a statement is “true”

Turns out it’s not always about corresponding correctly to the facts. Sometimes it’s more closely related to a moral ideal of “truthfulness”

[Experimental Philosophy @xphilosopher]

In this new paper, we look at some different dimensions on which beliefs vary:

- Is the belief deeply important to your identity?
- Would you change your mind if you got evidence against it?
- Is it best described in terms of credences (“pretty sure”), or is it more yes/no?

There’s growing evidence that something was going very seriously wrong in the classic early work on cognitive dissonance

Latest revelation is that the story of When Prophecy Fails was fabricated in fundamental ways

We judge many behaviours as praise- vs blame-worthy based on the value of a continuous quantity (eg reaction time).

Research by @dhbostyn & @xphilosopher finds we do not judge this based on a statistical norm, but on the behaviour’s perceived frequency:

In philosophy of perception, we find different intuitions pulling people in opposing directions.

These new studies show something about that opposition

It is not: different people having different intuitions. It is: each individual person having *conflicting intuitions*

[Experimental Philosophy @xphilosopher]

People sometimes face a conflict between intuition (system 1) and reasoning (system 2)

In cases like these, which will be seen as the person’s true self?

[Nick Byrd, Ph.D. @byrd_nick]

Might the concept of "good judgment" vary by framing or social roles?

Five studies of four nations (🇺🇸🇨🇦🇬🇧🇨🇳) found some words and roles were more associated with "rational" than "reasonable" (and vice versa).

Here is a ‘blame-praise curve’ for helping a friend in need

People think the average friend would help for more than 4 hours, but they think you would be praiseworthy even if you help MUCH LESS than the average

Our new paper explores these puzzling blame/praise curves
