📣 The difference between replicable and not replicable is not itself scientifically replicable. 📣 New work with Erkan Buzbas, showing that verdicts such as "X% of results replicated" are based on an inferential machinery that doesn't work. arxiv.org/abs/2604.26268
Screenshot of a paper's title page. Title: "The Difference Between 'Replicable' and 'Not replicable' is not Itself Scientifically Replicable". Authors: Berna Devezer and Erkan O. Buzbas, both at the University of Idaho — Devezer in the Department of Business and the Institute for Modeling Collaboration and Innovation, Buzbas in the Department of Mathematics and Statistical Science. Authors contributed equally. Corresponding author: bdevezer@uidaho.edu.
Abstract: Replication studies estimate the replicability rate of scientific results by aggregating binary verdicts of experiments. Exact replications are rarely attainable, so most replication sequences are non-exact. Experiments differ in ways that matter and do not share a single common data-generating process. We formalize two statistical interpretations of this non-exactness. In a shared latent rate model (benchmark), experiments are exchangeable and depend on a common random replicability rate. In a conditionally independent rates model (operational), each experiment has its own replicability rate drawn independently from a population distribution. Under the shared latent rate model, even small variability among replicability rates induces an irreducible variance floor on the estimated mean replicability rate that cannot be eliminated by adding more replications. Under the conditionally independent rates model, the degree of non-exactness is not identifiable from standard replication data, because one binary verdict per experiment contains no information about between-experiment heterogeneity. Researchers therefore cannot tell which precision regime they are operating in or whether high- and low-replicability sequences can be distinguished in principle. As a result, the usual data structure of one binary verdict per experiment cannot support reliable demarcation between "replicable" and "not replicable" results and systematically understates uncertainty, making high- and low-replicability sequences appear discrim…

Late to the conversation, but I'm kind of unbothered by this lack of replication. If the study is not internally valid to begin with, then being able to replicate it only means replicating systematic biases. And something tells me this is likely to be a bigger problem in the literature.

wow hard to squeeze this many falsehoods and speculations without evidence in a piece about other scientists tweaking their results. these people have written a book about science. this is pure rhetoric without engaging with theory or evidence. it's harmful and misleading. nautil.us/how-tiny-sho...
In the 21st century, the role and relevance of scientists have changed. Science is no longer triumphant: It is in the midst of a severe crisis. Public trust in scientific results and findings has dwindled, and science does not know how to regain credibility. This crisis has many facets. More than anything else, however, it is a credibility crisis. The public no longer believes that scientists merely make honest mistakes on the long and winding road to truth. Instead, scientists are increasingly seen as partial, ideological agents, activists in an armchair, or, worse still, simply fraudsters who fabricate or manipulate data and tweak the specifications of their empirical models to get their desired results.By itself, failure to replicate does not necessarily indicate, and certainly not prove, scientific fraud. Empirical results can vary for many reasons. However, replication analyses usually show that replicated effect sizes are, on average, systematically smaller and often statistically insignificant. If 90 percent of replications deviate from the original article in one direction that is less favorable to what the authors wanted to demonstrate, then these deviations are not innocent random errors or acts of nature. If the deviations were random, they would cancel each other out, and their mean would be close to zero.

Instead, these deviations indicate that many published results were likely tweaked, manipulated, or fabricated.Tweaking is potentially more damaging to science in the long run than data manipulation and fabrication. That might be hard to believe, since tweaked empirical results are likely to have smaller effects on the fabric of science than cases of data fabrication and manipulation. But the cumulative effect of tweaking can still be larger than that of data fabrication and manipulation because these strategies are rare, whereas tweaking is common.Make no mistake: Tweaking is not about changing the course of science. Nor is it, at least not primarily, about the misuse of public research funds (although it is a scandal that hard-working taxpayers fund the research of tweakers). Rather, tweaking is about scientists pursuing their own interests in a competitive, vulnerable system based on trust and on freedom from control by institutions that enforce rules.

Is the intentional manipulation of statistical quantities of interest always fraudulent? As with any categorization, there are gray areas.

This makes me think, the similar lack of resolution and desire to classify distinct issues and processes under broad and uninformative category labels prevalent in metascience may be inherited from psychology, given its central role in driving metascience agenda from the getgo.

For me this is a hard red line in psychological science. If you advocate the use of "silicon samples" you do not understand what it is we're supposed to be doing (and likely don't understand LLMs, or are a grifter). Luckily I haven't seen much of this among people I'd consider my peer group.
Except from Table 1 of Guest & van Rooij, 2025:

3) Displacement of Participants

“I can use AI instead of participants to perform tasks and generate data.”

The providence of the data used in these models indicates it is not ethically sourced, falling below standards for our discipline, involving sweatshop labour and no consent for private data used in experiments. The output can contain direct original input data (i.e. double dipping), but smoothed to remove outliers, conform to our pre-existing ideas of what it should look like (data fabrication), and all-round irreplicable. Psychology is meant to study humans, not patterns at the output of biased statistical models.

Exciting new @unimelb PhD opportunity at the intersection of Metascience & Public Policy, funded by a Volkswagen Foundation ‘Researching Research’ grant. Best part is you’d get to work with the amazing Dr Kate Williams, expert in research evaluation and impact measurement
findanexpert.unimelb.edu.au
PhD Opportunity in Wider Societal Value of Research and Consequences of its Assessment: A multi-country and multi-method study (MultiSocVal) : Find an Expert : The University of Melbourne
<p> The overarching project is funded by a German Volkswagen Foundation Grant. It brings together international collaborators from four countries – University of Melbourne, Humboldt University, Stellenbosch University, SWPS University, and from a range of disciplines including public policy, sociology, data science, political science, applied linguistics, philosophy and science and technology studies. </p> <p> The PhD candidate will be supported by an overarching research team, including academics, postdocs, research associates and research assistants, spread across the four countries. </p> <p> The overall goals of the group are described below, although there is considerable scope for the PhD candidatee to focus their thesis on an aspect of this work that interests them. </p> <p> Many governments are showing a political commitment to research impact in their respective environments by investing in research evaluation initiatives at different scales. Often the initiatives are characterised by pragmatism, with little attention to underlying value judgements. This creates an urgent need for comparative work with a strong theoretical and empirical basis to study the effects of national evaluation initiatives around impact and societal value. The overall project will address this need through a multi-country and multi-method study of research evaluation initiatives in Germany, Australia, the United Kingdom, Poland and South Africa. Bringing together an international and interdisciplinary team, the project seeks to: </p> <p> (1) produce a comprehensive cross-national and cross-disciplinary overview of research systems with regard to scientific and societal value; </p> <p> (2) investigate what is considered worthwhile research within and between countries; </p> <p> (3) compare the effects of different research evaluation initiatives around impact on research practice in different countries; </p> <p> (4) develop an integrated conceptual framework of scientific and societal value to improve science policy and science practice; and </p> <p> (5) advance stakeholders’ understanding of the effects of research impact assessment for better future evaluation. </p> <p> <strong>About you</strong> </p> <p> We are looking for a candidate with a strong academic background in a relevant discipline such as public policy, sociology, political science, science and technology studies, or a related field. The candidate will be intellectually curious and motivated by critical questions about the role of research in society. Ideally, the candidate will bring an interest in the changing landscape of research governance, including how ideas of value, worth, and impact are shaped and operationalised across national science systems. </p> <p> We welcome applicants with experience in qualitative, quantitative, or mixed-methods research. An enthusiasm for learning new methods – including bibliometric or computational text analysis, survey design, or innovative qualitative analysis – will be an advantage. The candidate will thrive in interdisciplinary and collaborative environments and be keen to contribute to an international research team spanning multiple countries and disciplinary traditions. Strong written and verbal communication skills, along with the ability to work independently and manage a sustained research project, are essential. </p> <p> This project offers considerable scope for the PhD candidate to shape their own research focus within the broader program, and would suit someone interested in contributing to both theoretical and practical understandings of how research is evaluated and governed in contemporary societies. </p> <p> <strong>Eligibility</strong> </p> <p> Domestic and International applicants may apply. You must meet the entry requirements for the <a href="https://handbook.unimelb.edu.au/courses/dr-philart">Doctor of Philosophy – Arts at the University of Melbourne (link attached)</a> including English language requirements and demonstrate excellent capacity and potential for research. </p> <p> As the successful candidate, You will demonstrae: </p> <ul> <li>An academic background in the field of sociology (of culture/science or related area), STS, library and information science, or public policy/research governance </li> <li>A relevant undergraduate and/or postgraduate degree with an average that equivalent to a H1 (80%) at the University of Melbourne, including H1 results in the Honours or Master’s thesis component; and </li> <li>Experience with qualitative analysis or quantitative analysis in the above fields </li> <li>The ability to write research reports or other publications to a publishable standard (even if not published to date) </li> <li>capability to manage projects effectively, meet deadlines and achieve outcomes within a specified timeframes. </li> </ul> <p> <strong>How to submit an expression of interest</strong> </p> <p> Please submit your expression of interest (EOI) via the ‘Submit Expression of Interest’ button by 15 July 2025. </p> <p> Your EOI must include: </p> <ul> <li>A short description of how the project aligns with your interest and experience, an overview of how your might approach the project goals, and an outline of three relevant references from the literature with a description of how they relate to the project </li> <li>A CV that highlights your relevant academic achievements and any relevant professional experience including the names of two academic referees. </li> <li>Higher education academic transcripts that give detailed information of the individual marks received in your university-level qualifications to date </li> <li>An example of your written academic work (e.g. Honours or masters thesis or peer-reviewed journal article) </li> </ul> <p> For more information about our PhD program and application process, please visit <a href="https://arts.unimelb.edu.au/study/graduate-research"><strong>this website</strong></a>. </p>

🚨Preprint alert! 🚨 In this one, @mieronen.bsky.social and I argue that using network psychometrics, DAGs or BNs to study predictions of the network theory of psychopathology (NT) is conceptually incoherent. Why? NT either directly contradicts or cannot support causal sufficiency! 1/11

Allein gestern waren wieder 120.000 Menschen auf der Straße gegen den Rechtsruck. Bei den Demonstrationen 2024 waren es insgesamt über 4 MILLIONEN Menschen. Die größte Protestbewegung seit der Wiedervereinigung, aber oft nur Randnotizen in vielen Medien. Und wir wundern uns, warum die AfD zulegt.

Are psychometric networks sufficiently supported by data such that one can be confident when interpreting its results? We analysed 294 psychometric networks from 126 papers with the Bayesian approach to address this question @jmbh.bsky.social Sara Ruth van Holst @maartenmarsman.bsky.social 🧵
