New @nature.com collection on #trust in #science! A little anecdote from my conference travels opens the editorial – and in @helenpearson.bsky.social’s feature story I share my thoughts on what surveys (don’t) tell us about a “crisis of trust in science” and implications for #science #communication💡

NEW: Is there a 'crisis' of public trust in science? It can feel that way — with attacks on research in the US and growing rejection of vaccines. I investigated for @nature.com - and found some surprises. My feature article is out today and a short🧵here www.nature.com/articles/d41...

"Drawing on a 20.3-million-query audit of ChatGPT, we map systematic biases in the model's representations of countries, states, cities, and neighbourhoods. From these empirics, we argue that bias is not a correctable anomaly but an intrinsic feature of generative AI”. ht: Dagmar Monett

The silicon gaze: A typology of biases and inequality in LLMs through the lens of place - Francisco W. Kerche, Matthew Zook, Mark Graham, 2026

This paper introduces the concept of the silicon gaze to explain how large language models (LLMs) reproduce and amplify long-standing spatial inequalities. Draw...

Looking forward to visiting @unileiden.bsky.social and speaking in the research seminar series of @cwtsnl.bsky.social this Friday. Come to CWTS or join online! 👇

CWTS | Leiden University@cwts.nl · 8mo ago

📣 In our next research seminar, @nielsmede.bsky.social from @w-u-r.bsky.social will talk about 'Public opinion and communication about science: Global evidence from a 68-country survey'. 📅 Friday, 23/1/2025 | 3:00-4:15 PM (CET) 📌 Online & at CWTS www.universiteitleiden.nl/en/events/20...

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.

This plot shows average response rates of the European Social Survey. Between 2002 and 2023 the have fallen from 61 to 41 per cent.This plot breaks down ESS response rates by country. In almost all countries, the rate has gone down over time - in some cases, like Sweden, quite dramatically so.

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...

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

How the World Talks About Science

Our new international study finds that science communication looks very different depending on culture, media systems, and access to technology.

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/

AI Surrogates and illusions of generalizability in cognitive science

Recent advances in artificial intelligence (AI) have generated enthusiasm for using AI simulations of human research participants to generate new know…
