In line with the 'credibility revolution', we are thinking about research designs that allow us to get closer to causal effects. Those who use surveys have often turned to survey experiments. At the same time, survey response rates have dropped considerably. Below are the figures for the ESS.

🧵 1/ 🚨 New paper out in PLOS ONE! w/ @caropradier.bsky.social @benzpierre.bsky.social @natsush.bsky.social @ipoga.bsky.social @lariviev.bsky.social We studied 43k authors and 264k citation links in U.S. economics to ask: 👉 Why do some papers cite others? 🔗 journals.plos.org/plosone/arti...

Fake expert and pseudo-scientist labels are increasingly used in science and public debates to delegitimize actors or claims, often in the context of misinformation 📰 In our newest publication in Communication Theory we explore what such terms actually mean. 👇

📰 Quantitative research on science communication requires suitable data. When it comes to academic press releases, that data is scarce. In a new paper, we introduce a dataset of more than 500,000 press releases published on @eurekalert.bsky.social. doi.org/10.1038/s415...

@matthewfacciani.bsky.social, co-author of our latest study on science communication behavior in 68 countries, just published a blog post with a great summary of the main results. Check it out! ⬇️

How do people around the world encounter science, and what shapes those encounters? Our new global study found that social media now carries much of the world’s science content, but local culture, infrastructure, and curiosity still determine how people engage. #ScienceSky #scicomm

Can AI simulations of human research participants advance cognitive science? In @cp-trendscognsci.bsky.social, @lmesseri.bsky.social & I analyze this vision. We show how “AI Surrogates” entrench practices that limit the generalizability of cognitive science while aspiring to do the opposite. 1/

So happy to see this out! 🎉 We surveyed people from 68 countries about how they encounter and engage with information about science! See the thread below for a summary of the main findings 👇 Congratulations to the whole team, especially @nielsmede.bsky.social and @colognaviktoria.bsky.social 👏

Published today: One of the biggest #science #communication studies to date. We asked 71,922 people in 68 countries how they #engage with information about #science and combined the data with several country-level factors: journals.sagepub.com/doi/10.1177/... #OpenAccess

New publication alert🔓🚨 Toxic speech is widespread on social media – but do users mirror the toxic behavior of their ingroup or react defensively to outgroup toxicity? Our new paper in JCMC examines how ingroup and outgroup behavior shape the spread of toxicity on social media.

If you've been reading that fantastic new paper by @dasalgon.bsky.social & @tevoelker.bsky.social on how mainstream parties lose if they adopt far-right issues: We looked at a case study & found similar dynamics for media. This was partly based on data from Daniel & Teresa!❤️ bsky.app/profile/curd...

New paper out on trust in science in the International Journal of Public Opinion Research. 🙏 to @nielsmede.bsky.social and @colognaviktoria.bsky.social for initiating the TISP project and to @juliametag.bsky.social for her helpful input throughout the project. Free-access link: shorturl.at/4VBAJ

Is research performance related to academic freedom? A preprint co-authored with @lutzb.bsky.social conducts a large-scale empirical analysis on the national level to this question. osf.io/2mh8f #academicfreedom #AcademicFreedomIndex Short 🧵

Finally! 🤩 Our position piece: Against the Uncritical Adoption of 'AI' Technologies in Academia: doi.org/10.5281/zeno... We unpick the tech industry’s marketing, hype, & harm; and we argue for safeguarding higher education, critical thinking, expertise, academic freedom, & scientific integrity. 1/n

In this new Commentary in @natclimate.nature.com, I reflect on the recent focus on truth discernment in #misinfo research and argue that this outcome alone may not be beneficial to society if interventions do not improve behaviour and other outcomes because... 1/ www.nature.com/articles/s41...

“De wetenschap heeft een tweeledige rol: als locomotief van de vooruitgang, maar ook als rem om de trein van de geschiedenis op de rails te houden.” Robbert Dijkgraaf in @nrc.nl Trump en de tech-trawanten www.nrc.nl/nieuws/2025/... www.nrc.nl/nieuws/2025/...

How much do people really reject science? New paper out doi.org/10.1177/0963... In four studies, we asked Americans—including flat Earthers, climate change deniers and vaccine skeptics—whether they accepted basic scientific facts. The result? A surprisingly high level of agreement. 👇

🚀 We’re live! The Political Communication Division of @nefca.bsky.social is now on BlueSky. Follow us for updates on research, events, and conversations in the PolCom community.

@nielsmede.bsky.social is opening our workshop based on his TrygFonden * @ddc-sdu.bsky.social fellowship on countering science related online harrassment - very excited to discuss how to support science communicators with a stellar line-up of academics and stakeholders!

thrilled that our guides for #OpenScience in developing countries is now published in AMPPS of @psychscience.bsky.social: journals.sagepub.com/doi/10.1177/... Please see the thread for details

🧵 Can you predict whether behavioral interventions will work in new contexts? … probably not, right? In our new paper with @dggoldst.bsky.social @dilipsoman.bsky.social @susanmichie.bsky.social, we dive into how to better understand and improve generalizability. rdcu.be/ewD2z Summary👇

It’s not just social media algorithms that determine whether content goes viral. Research by @steverathje.bsky.social and @jayvanbavel.bsky.social finds how the psychology of spreaders and consumers interacts with the environment also significantly influences virality: buff.ly/q17VnXN

Which is why the way reporting is done is crucial... "We find: It’s not necessarily firsthand experience of extreme weather events. Instead, it’s whether people think that these events are linked to climate change."

What if science communication wasn’t just about facts—but about trust, humility & shared values? This new agenda from PNAS calls for participatory models to replace top-down fixes. In this ultra-polarized environment, it’s about co-creation, not just correction. What are your thoughts? 🧪🧬🔬

Excellent new study in @actapolitica.bsky.social: @roderikrekker.bsky.social uses 15 years of representative panel survey data (2007-2022, n = 19,084) to show how science skepticism is linked to political discontent in the Netherlands ⬇️

New paper: What increases people’s support for policy responses to #climate #change? ✊ We find: It’s not necessarily firsthand experience of extreme weather events. Instead, it’s whether people think that these events are linked to climate change. Here is the paper: www.nature.com/articles/s41... 🔎

🚨 How do exposure to extreme weather events and the subjective attribution of these events to climate change relate to climate policy support across the world? 🔥🌎 Find out more in our OA article published in Nature Climate Change 👇 1/7 🧵 www.nature.com/articles/s41...

Ade Zürich, hallo #Wageningen! This week I started my new position as Assistant Professor at @w-u-r.bsky.social ✨ Thanks a lot for the warm welcome – I'm very excited about what’s ahead! At the same time, I'm very grateful for the years I spent at @ikmz.bsky.social. Merci vielmal und uf widerluege 🫶

This was a remarkable milestone in our careers, and the next steps look very promising with our TISP leaders @colognaviktoria.bsky.social and @nielsmede.bsky.social. If you haven’t read our article yet, it’s fully open access. #PhilSky #AcademicSky

🤔 How much do politicians engage with academic researchers online? In my latest paper, I find that politicians from 12 countries rarely engage with researchers on social media, but this can change when expertise gains salience Preprint: osf.io/preprints/osf/wqbe4_v1 🧵👇

Young adults who overestimate their knowledge about climate change try to reach out to politicians and persuade others more often. This is what we find in our brand new OA paper. See @nielsmede.bsky.social amazing thread for more info 👇

Science communication meets poetry: I was invited to contribute an audio essay about our study on trust in scientists to “The Academic Minute” by @wamcradio.bsky.social, hosted by @aacu.org President Lynn Pasquerella. Thanks a lot for having me! 🎙️ 🔗 academicminute.org/niels-mede-u... #scicomm #TISP

The Guidelines for good Research Communication are now available in English. They provide orientation and support for research communicators. They specify the roles and responsibilities of the actors involved and include a checklist for practice. 📄 wissenschaft-im-dialog.de/documents/42... #SciComm

"On a weekly basis more than 90% of people use weather forecasts, job market reports, food safety warnings and other information that is based on federal science. But only 10% ... are concerned that cuts to federal support for science might impact their access to [it]." www.npr.org/2025/05/06/n...

Excited to present a workshop on misinfo at the “Listen, Engage, Connect: Explore the Science Communication Arena” Summer School at the University of Geneva. Runs from June 23-27. Ideal for students, early-career researchers, science communicators. Register before 31 May at bit.ly/scicomm25

I cowrote a column in @nature.com about the need for scientists to secure public trust in an age of polarization We discussed strategies that could restore trust in research and encouraged more research on the topic. You can read the full column here: www.nature.com/articles/d41...

New paper with #IsabelVillanueva and @kaipingchen.bsky.social ✨ We tested how online users discuss #plagiarism, data #fraud, #replication failure, and (unintentional) errors by scientists – based on 19,462 X posts by @retractionwatch.com and 22,936 user replies: journals.sagepub.com/doi/10.1177/...

Mis/disinformation research officially cancelled. Understanding the creation, content, distribution, and susceptibility is one of today’s key scientific and societal challenges. Researching this is not free speech infringement. Such a claim is intentionally misleading. www.nsf.gov/updates-on-p...

Just been reading this great blog post by @dingdingpeng.the100.ci on accessible technical writing. Lots of good advice (some of which I knew, some was new to me) clearly laid out in one handy place! www.the100.ci/2024/12/01/w...
