New publication. Congrats to the whole team, and especially @paulbertin.bsky.social who led this effort. Thanks also to the editor (Nicolas Sommet) and reviewers, who desserve credit for improving our paper.

We found robust evidence that lower freedom of speech increases conspiracy beliefs.

This effect was consistent across contexts and held even when controlling for perceived levels of democracy, highlighting the specific nature of this relationship.

🚨 New paper out in the European Journal of Social Psychology!

Across one study using aggregated nation-level data and four preregistered experiments, we examined how freedom of speech within a society influences belief in conspiracy theories.

I am so excited to announce the publication of my first PhD paper, written in collaboration with Laurent Licata and amazing participants!

Merci de partager !

Exactement 😂

Merci à @adrienfillon.bsky.social et @nathlarigaldie.bsky.social pour ce super moment 😊

Version clickbait du titre : ils découvrent en live l'identité du pair qui a expertisé leur papier… leur réaction est incroyable !

If you work in psychology in a research area without Registered Reports, you will see that the main hypotheses in papers are almost always supported. If your peers publish Registered Reports, you will also have access to null results, which should be very common. doi.org/10.1177/2515...

Great talk by @rritabajraktari.bsky.social at @bapsciences.bsky.social 2025, with a proud supervisor @olivierklein.bsky.social!

I am super happy to back my most appreciated and trustworthy partner in crime in this great piece (in all objectivity of course)! #metascience #transparency #virtuesignaling

This trilemma may have detrimental consequences for open science practices, turning them into a form of virtue signalling that compensates for low transparency.

To learn more about the trilemma, its consequences, and potential solutions to alleviate its pressure, check out the open-access article:

New publication with my dearest friend, @kenzonera.bsky.social!

We propose that multi-study articles can hardly achieve conceptual novelty and statistical consistency while remaining transparent.

Fulfilling two of these criteria considerably reduces the probability of satisfying the third one.

Are there any fully online or hybrid conferences in social/political psychology?

Merci 😁

S/O to YouTubers (Wiloo, Les Outsiderz) and @lequipedusoir.bsky.social journalists (l'immense et regretté Didier Roustan, Guillaume Dufy, Philippe Sanfourche) who shared our survey.

Thanks also to @olivierklein.bsky.social for his help in designing nice figures!

Boycott behaviors may be hard for sports fans to maintain due to the lack of alternative products.

Ultimately, boycott may reflect low fandom rather than high political engagement.

In the end, lasting boycotters may be those uninterested in sports events, making the boycott poorly consequential.

Even more puzzling was the finding that this decrease occurred regardless of French fans' political concerns about minorities and environmental issues—the best predictors of boycott intentions.

In other words, politicized fans struggled to maintain the boycott.

Then, we compared fans' intentions before the WC with their actual boycott behavior after the tournament.

We observed a decrease in all countries, but it was only significant in France—likely due to limited statistical power in other countries and the strong performance of the French team.

We investigated boycott intentions in France, Belgium, Canada, and Switzerland (N = 1,635).

Boycott intentions were tied to concerns about environmental and minority issues.

Rejection of the boycott was best predicted by strong identification with the team and enjoying football’s aesthetic appeal.

New paper on sports fans and political behaviors now in press at bsky.app/profile/ispp...

In late 2022, @paulinegrippa.bsky.social and I conducted an intercultural, longitudinal study on fans' motives for (not) boycotting the 2022 World Cup.

How do different "Great Replacement" conspiracy narratives (blaming relatively powerful left-wing elites or relatively powerless Muslim communities) affect radical collective action intentions against different targets across the political spectrum?

Dans mon ancienne ED, c'était 3 publiés. J'ai fait du forcing pour pouvoir soutenir avec 2 publiés et 2 soumis.

Certaines disciplines ne voyaient pas les thèses articles d'un très bon œil et avaient imposé des critères inatteignables (j'étais la première thèse article soutenue sous ces critères).

Making materials openly available and easy to retrieve is crucial for facilitating this kind of replication effort and ensuring a healthy development of the field.
