- Reposted by Jan FeldYou can do this right now: Think of a person who wrote a paper you love, whose work influenced or helped you, or has made your professional life better. Search up their email address. Shoot them a quick email of thanks. It means so, so much. This is a rough time of year, share some joy.
- Reposted by Jan FeldI used to think that people use the “weasel word causal inference strategy” (“our analyses show that X is an important predictor of…” followed by conclusions that are clearly causal) for the sake of plausible deniability. But I’m revising that now, because often deniability *isn’t* plausible.>

- Reposted by Jan FeldReviewers are more likely to approve manuscripts if authors agree to cite their work than those who don't get cited. Thanks to @aidybarnett.bsky.social, @balazsaczel.bsky.social and @econfeld.bsky.social for chatting with me for this story! www.nature.com/articles/d41...
- Reposted by Jan FeldOnce upon a time, two science journalists had an idea for a blog about retractions. And on Aug. 3, 2010, Retraction Watch launched. And now, 15 years and 6,700 posts later, that work seems more important than ever. Happy 15th anniversary, Retraction Watch.
- Reposted by Jan FeldInteresting read, but worth considering (as the article does) the selection bias introduced by a) who is willing to initiate an adversarial collaboration and b) who manages to compete and publish it.
- Reposted by Jan FeldOur special issue seeks to foster novel theoretical and empirical papers that treat scaling as an object of study in its own right—exploring its methodological foundations, economic incentives, institutional challenges, and pathways to impact. Please spread the word! ideas.repec.org/p/feb/artefa...
- Reposted by Jan FeldToday, scaling has evolved far beyond its origins as a mere objective. It now represents a rich domain for scientific inquiry, demanding contributions from economics and allied disciplines. As such, I am excited to announce a special issue on scaling at the JPE-Micro!

- Reposted by Jan FeldOne single study is never enough. Check out this short piece by my friend and coauthor @econfeld.bsky.social on meta-science applied to Econ problems. I love the way he takes the reader by the hand and tell us his humble story.👇🏽👇🏽👇🏽 www.wgtn.ac.nz/business/res...
- "Other researchers began citing our work as evidence of a universal truth... This interpretation was flattering but misleading." See my discussion on why one study is not enough here: www.wgtn.ac.nz/business/res...
- "It’s a common story in the social sciences, where findings from specific studies are often generalised far beyond their original context. I realised that I, too, was guilty of this."
- Reposted by Jan FeldNew blog post! If you're a substantive researcher, you mainly do statistics to answer substantive questions. So let's stop putting the statistical model first. www.the100.ci/2024/08/27/l...
- Regression: it's not just for causality! Spirling & Stewart argue it’s the tool for uncovering the best explanations. Think of it as detective work—solving the mystery of social data, one regression at a time. github.com/ArthurSpirli...
- This can be done even with regressions that don't get past the identification police.
- Example from the article: The rise in violent civil conflicts began before the Cold War ended, suggesting the Cold War's conclusion wasn't the cause. Regression can provide insights into historical events, even without clear exogenous variation.

- Are teachers *generally* better at teaching students of their own sex? NO in primary education, YES in secondary education. A 🧵 generalizability and same-sex teacher effects www.zora.uzh.ch/id/eprint/23...
- We are looking for what philosophers of science call phenomena: stable and general features of the world. Are same-sex teacher effects a phenomenon? Are they general and stable like sex-differences in human height? Or are they context-dependent and fleeting, like trends on X?
- We usually find phenomena in the social sciences by: 1) accumulating evidence from many studies 2) reflecting on the evidence (e.g. with literature reviews or meta-analyses)

- We ran a 2-stage experiment to estimate the causal effect of writing quality. Stage 1: We language-edited 30 academic papers for clarity. All papers were written by PhD students in economics. 2/7
- Stage 2: We asked writing experts and senior economists to evaluate the original and language-edited version of the same papers. No evaluator saw both versions of the same paper.
