- Réception de la 3e édition de l'incontournable Analyse des Donnees : Approche par Comparaison de Modèles. Merci aux collègues 🙏 @vincentyzerbyt.bsky.social & @marinerougier.bsky.social pour cette réactualisation et l'opportunité d'entrainer doctorant-e-s dans ces approches structurantes !
- 📢 Post-doc position – Toulouse (France) 🇫🇷 A post-doctoral position (12 months) is open at CNRS in Toulouse to work with me on the relationship between signal detection theory, conspiracy beliefs, and perceptions of corruption... 🔗 emploi.cnrs.fr/Offres/CDD/U... Feel free to share!
- I'm not a big fan of rituals, but I truly wish us all a better world! Let's remember that people are not their governments. Several of the latter must be stopped now, while many of the former must be supported and empowered to change the game.

- Reposted by David C. Vaidis📢 Call for submissions for #SIPS2026!📢 The SIPS community will meet next year, and we look forward to seeing you at the conferences! Don't forget to send your submission for the conference before January 23 (for the in-person conference) or February 27 (for the online conference).
- What is the current position of @improvingpsych.org concerning the Washington meeting after the last Trump's administration proposal? Requiring 5 years of social media history, phone numbers, and email addresses is invasive and concerning for anyone who values privacy and freedom of thought.
- I didn't want to get into this discussion, but after seeing strong reactions to Kelly (2025), I think it's worth helping colleagues think more critically about what the paper actually shows—and doesn't show. Spoiler: not the bombshell some claim. #SocialPsychology #CognitiveDissonance
- Excited to be in Limerick for a few days, collaborating with @paulmaher.bsky.social, and presenting a talk today on cognitive dissonance and the replication crisis! @ulpsych.bsky.social
- 🎉👶 Welcome to the last new born in the Open Science effort! Replication Research is a diamond open access journal dedicated to robust, transparent and reproducible science. #OpenScience #ScientificPublication #Replication #OpenAccess
- Reposted by David C. VaidisWas looking into what Cognitive Scientists mean by ‘domain-general’ cognition, and then hit upon this. This is definitely NOT how we use that term. Tip: read the last sentence to understand what went wrong here. Sigh.
- Oups. 😄 It seems my close colleague forgot to cut my joke at the end of the sentence... And then not the editor, nor the people in charge of editing considered necessary to change it before publication! #SciencePublication #FunButSad #SadButTrue #FrenchAcademic
- 240,245 participants in a single study, not too bad. The effect size is modest, but ecological validity is high due to real-world implementation! #BehavioralScience #SocialPsychology #Megastudy #ClimateChange #ImplementationScience www.sciencedirect.com/science/arti...
- The 4th Big Team Science Conference (aka #BTSCON) will be held online October 6-8. A unique opportunity to discuss, join and anticipate the future of BTS. Registration is free/'what you can' but beware submission deadline is short! (31st July). bigteamscienceconference.github.io/submissions/ #psysci

- Shame on Wiley!
- NEW: Statement from the PCI RR Managing Board on the withdrawal of Infant and Child Development as a PCI RR-friendly journal, and the decision by Wiley to refuse preprints that have been peer-reviewed by @peercommunityin.bsky.social / @pci-regreports.bsky.social Read here ➡️ osf.io/tn8mh

- In France, only 3% of public spending goes to research — just €27B budgeted for 2025. Shockingly low for a country that prides itself on innovation. 🧪 Underfunded labs 🧠 Brain drain 🏫 Poor faculty conditions Investing in the future isn’t optional. #Research #Science #France #WhereGoesTaxes
- Great having @protzko.bsky.social at the (big) Lab these past two weeks! Inspiring discussions and exciting ideas in #metascience. Thanks for the engaging talk at the #AtelierMMS (Methodology, MetaScience & Stats Lab Meeting). #UniversitéDeToulouse #UT2J
- Our EIM model paper with Ben Aubert-Teillaud and Alex Bran "Expectation violation and cognitive dissonance theory" was among the top 10% most viewed in EJSP in 2023... Good for an 'august' paper ! 😏 📄 onlinelibrary.wiley.com/doi/full/10.... #CognitiveDissonance #FormalizedModel #SocialPsychology
- Comment aider les chercheurs disposant de moins de ressources ou des réseaux moins développés à faire de la recherche ? L'étude bit.ly/GrEenwIch cartographie cela et s'adresse à des C, EC et post-doc. 20GBP à la clé pour les participants (voucher ou don). #FrenchAcademic #recherche à diffuser

- Reposted by David C. VaidisHow accurately do citations reflect the original research? Do authors truly engage with what they cite? In a new study, we analyze millions of citation sentence pairs to measure citation fidelity and how it varies depending on authors’ engagement with prior literature. arxiv.org/abs/2502.20581 ⬇️
- Another time, other practices, other threats. Yet in this dark period, Merton's take on the norms of science remains strikingly contemporary, relevant and necessary! #ElonMusk #Science #Openscience #Metascience #academicsky law.unimelb.edu.au/__data/asset...
- A meta-epistemological problem... In short, this resolves the replication crisis with an upper class problem, as understanding knowledge itself IS the problem! Happy Friday.
- US is firing researchers? Bad news 😤 (stupid choice) but lucky opportunity for you! Liberty🗽 🇫🇷 France's application session is opening very soon! Transparent process, tenured positions and now a much easier portal in English. odyssee.enseignementsup-recherche.gouv.fr/accueil?lang... #sciencesky
- Got the same from France, with translation. Due to its allegiance and the power we grant it, Google threatens democracy by rewriting history. What a shame! #Google #democracy #MakeAmericaAdultAgainNotDangerousBullyingAsshole
- We talk a lot about predatory journals, but I just encountered my first PREDATORY PODCAST!🚨 www.scipod.global They reach out, set up a meeting, then—when you ask about their economic model—you realize they want £1000 for a 10-min recorded podcast. That’s here you run away. #PredatoryJournal #Scisky

- Hoooops too bad. I won't change my practice concerning RR but I will delve into their registered report! I also think that finally, RRR are RR but I bet they are much more cited than any regular paper!
- Reposted by David C. VaidisRoy Baumeister called ego depletion "one of the most replicable findings in social psychology." As someone who spent 20 years studying it—and ultimately had to admit it wasn't real—I have to respectfully disagree. Here's my perspective of what went so wrong.
- Reposted by David C. VaidisDoes the culture you grow up in shape the way you see the world? In a new Psych Review paper, @chazfirestone.bsky.social & I tackle this centuries-old question using the Müller-Lyer illusion as a case study. Come think through one of history's mysteries with us🧵(1/13):

- Is there a badge for Registered Reports? I couldn't find one on the COS initiative page (www.cos.io/initiatives/...), which is unfortunate. Last year, I created one for a talk I gave—perhaps it could be useful to others or inspire the creative ones? #AcademicSky #RegisteredReport #OSF
