Hello friends and foes are you ready for some effect size standardisation discourse well too bad because you're getting it anyway! (unless you scroll away please don't) Quick thread on a new commentary-like preprint with @protzko.bsky.social, Lakens, @malte.the100.ci, & @ruben.the100.ci 1/6

Now accepted at AMPPS: It's not just p-values that get hacked. We present evidence that the distribution of published Cronbach’s alpha values is also distorted in some way due to hacking and/or bias. @malte.the100.ci @ruben.the100.ci @taymalsalti.bsky.social osf.io/preprints/ps...

This blog post is *excellent* for teaching -- it illustrates concerns about what we can learn from observational studies, but also the political dimension of evaluation in general, and it also discusses implausible effect size estimates. statmodeling.stat.columbia.edu/2024/06/13/a...

Ever wondered how people choose numbers on emotion scales in #ESM studies and whether they stay consistent? 🤩 We just finished data collection for our study aimed to uncover response processes in emotion assessment (i.e., how participants interpret & respond to questions) (1/8)

Sky people: I’m thinking about writing a non-technical introduction to the age/period/cohort problem. Does such a thing already exist? Would there be an audience? Do you have any existing favorite papers on the topic?

Neither sexual satisfaction or sexual frequency significantly predicted the probability to switch, questioning the idea that women discontinue hormonal contraceptive use because of hormonal side effects on sexuality.

Why do women switch their contraceptive method? We have a new preprint led by Chiara Draxler with a focus on sexuality-related predictors: osf.io/preprints/ps... Contraceptive satisfaction - but not sexual satisfaction or sexual frequency - predicts contraceptive switches.

Our failure to reproduce Anderson et al (2023), The Myth of Man the Hunter, is now published: 🧪 authors.elsevier.com/c/1j2qf3tz49...
In The Myth of Man the Hunter, Anderson et al 2023 claimed to discover that women hunt in 79% of hunter-gatherer societies. Did hunter-gatherer researchers get it wrong? In an effort lead by @vivek123.bsky.social, we attempted to reproduce their study. These are the fatal flaws we found🧪 (1/n)

So happy to see this. I don't think I'm the only postdoc that thinks this would be a dreamy full-time job? (Be paid to thoroughly read fascinating papers in detail, put your critical skills to good use, and contributing to the validity & trustworthiness of science?!)
Error checking is an important service to science, but it doesn't pay the bills. But what if it did? Introducing ERROR, a bug bounty program for science to systematically detect and report errors in academic publications error.reviews

One unintended consequence of the generalizability discussion is that it provides a justification for the most milquetoast limitations sections--"We looked at X & Y in Z1; we cannot make statements about Z2"--neither meaningfully engaging with generalizability, nor with major threats to validity.>
