Join our Replicability Project: Health Behavior! We have 55 replication studies underway, our target is 65-70. We are only recruiting for secondary data replications--i.e., using existing data to test the original question. Here's a list of studies we think could be feasible. If interested...

Many common practices in US animal agriculture (cutting off chickens' beaks or castrating calves without pain relief) are seen as unacceptable by the US public. @faunalytics.bsky.social An earlier study in the UK found very similar results. faunalytics.org/public-accep...

A recent study purports to have found that multilingualism protects against accelerated ageing. I've taken a closer look at it, and it doesn't look good. New blog post: "Does multilingualism really protect against accelerated ageing? Some critical comments" janhove.github.io/posts/2025-1...

Did you know that from tomorrow, Qualtrics is offering synthetic panels (AI-generated participants)? Follow me down a rabbit hole I'm calling "doing science is tough and I'm so busy, can't we just make up participants?"

One myth about empathy not included is that people know how empathic they are. Bill Ickes has shown no significant correlation has been found between the scores on various empathy scales and the measurement of empathic accuracy.

Adversarial collaboration by @jordanaxt.bsky.social et al suggests implicit racial bias has a small (2.5%) additional effect on discriminatory behaviour, but explicit racial attitude predicts 45% of discrimination: buff.ly/0ws4BAL TL;DR:🧵https://buff.ly/Cr0jLml

What do children and adults in 33 communities think about animal minds?

Many psychologists are treating LLMs as if they are the mind of god. This study had chatGPT rate how central academic disciplines are to various constructs. Why would chatGPT know this? Where is the evidence its ratings are reliable or valid? compass.onlinelibrary.wiley.com/doi/full/10....

🚨STOP, replication time!🚨 Does Feeling “Right” Make the Good More Good (and the Bad More Bad)? Achar & Lee found that when people experience regulatory fit, moral predispositions get amplified—moral folks act more moral, less moral folks act less moral. Big, exciting claim!

Are people on the political right more rigid in their thinking? Or is it people on both extreme ends of the political spectrum? This adversarial collaboration found some evidence for both but differences were generally small. doi.org/10.1111/pops...

A diverse range of mammals once roamed the planet. This changed dramatically with the arrival of humans, who have become the dominant species through our own population, as well as the animals we breed and raise for food. What is the distribution of the global mammal kingdom today?

🚨 SynthNet is out 🚨 Researchers propose new constructs and measures faster than anyone can track. We (@anniria.bsky.social @ruben.the100.ci) built a search engine to check what already exists and help identify redundancies; indexing 74,000 scales from ~31,500 instruments in APA PsycTests. 🧵1/3

In light of record submission rates and a large volume of AI-generated slop, SocArXiv recently implemented a policy requiring ORCIDs linked in the OSF profile of submitting authors, and narrowing our focus to social science subjects. Today we are taking two more steps: /1

Few US consumers were confused by what plant-based meat and milk replacements contain when current labels were used (e.g., "veggie burger"). Changing the labels in line with policy proposals (e.g., to "veggie patties") did not increase understanding. link.springer.com/article/10.1...

Participants from the US donated more to a girl (vs. a boy) in need. Participants from China showed the opposite pattern. onlinelibrary.wiley.com/doi/pdf/10.1...

🚨 New working paper! How well do people predict the results of studies? @sdellavi.bsky.social and I leverage data from the first 100 studies to have been posted on the SSPP, containing 1,482 key questions, on which over 50,000 forecasts were placed. Some surprising results below.... 🧵👇

All of the teams did better than randomly selecting scores and none of the teams did better than selecting 0.5 as a constant score. Round 2 is getting started. If you think you can do better, join! Prizes: $15k for 1st, $12k for 2nd, $6,750 for 3rd. More info: www.cos.io/blog/predict...

Round 1 results of our predicting replicability challenge are released! The Challenge capitalizes on interest in using AI methods to do scientific tasks. Ten teams tried to predict replication outcomes from unreleased SCORE findings. Results? Not so hot! Post: www.cos.io/blog/predict...

@sjdm-tweets.bsky.social Why does "1-in-X" (e.g., 1 in 50 vs. 20 in 1000) feel riskier? The answer: It's the availability heuristic! We found that the 1-in-X ratio is easier to mentally visualize and recall examples for. Risk Communication Poster at #SJDM2025 in Denver, Colorado!

This is a very interesting paper but the empirical evidence presented for an increase in connectivity (in their Fig. 1E) is rather problematic. A little thread 👇(1/7):

So why hasn’t this happened yet? 🤷‍♀️ Because for-profit publishers have distorted Open Access so thoroughly that many authors now believe their only OA option is to pay astronomical APCs. And we ask researchers to publish OA… while rewarding prestige controlled by the same oligopoly. 5/n

Why? 🤑 In just the last 5 years, 4 publishers made $US 41 billion in revenue and $14.7B in profit - money that largely comes from taxpayer-funded research budgets. For context: the entire 2024 NSF budget was $9B USD. @elsevierconnect.bsky.social made $3.9B that year at a 38% profit margin. 2/n

Over the past months (and at least 11 versions!), I was lucky to work with 11 amazing colleagues on a call to action to reform academic publishing. Not another declaration, but an appeal to our powerful friends, research funders & institutions, to Stop the Drain of Scientific Publishing. 1/n

I hate demand characteristics, but many other pre-registered experiments *have* found the effect. We discuss in this meta: online.ucpress.edu/collabra/art...

Prediction: Social psychologists will still insist that the book's thesis is valid, thereby ironically validating its thesis

I’ve spent the last 8 years(!) working from the position that HiTOP relies too much on analyses of traditional diagnoses, baking in limitations of the DSM, and that we need to move to symptom-level analyses to fix it It turns out that rebuilding HiTOP from the ground up doesn’t change much 💀 1/
