Lego Science is research driven by modular convenience.

When researchers combine methods or concepts, more out of convenience than any deep curiosity in the resulting research question, to create publishable units.

This is good. Authors ask an LLM to write a systematic review. The LLM states ‘prospectively registered’ and includes a fake registration number. When queried, authors send a corrected reg number…which has been created after the query. You love to see it. Happy new year!

Tomorrow I’ll be speaking on a panel for the WHO webinar Social Health and Digital Play: A Conversation, Not a Conclusion. I’ll be sharing insights from a recent Delphi study focusing on priorities and future directions in video game research.

Too many significance tests!!

Made this little graphic for my #stats class, showing the various kinds of (N)HST and how interpreting confidence intervals can replace all of them.

Made with #rstats #ggplot (duh)

There’s nothing about those publications to brag about

Ian Hussey @ianhussey.mmmdata.io · 1d

Is it a bad time to tell you I had 12 publications upon graduation? That lab was trained in 🔪🥓

Ian Hussey @ianhussey.mmmdata.io · 1d

One thing to bear in mind is that people can postdoc here for a much longer time from what I know of the US, and this changes what the role is imo. There are even small numbers of tenured postdoc positions. There are many highly technical 7th+ year postdocs around.

Ian Hussey @ianhussey.mmmdata.io · 1d

Seconded for OS, and not even as a virtue: many PIs have OS expectations or requirements on them that they might not have the skills to fulfill alone, and rely on postdocs to drive forward.

Ian Hussey @ianhussey.mmmdata.io · 1d

I presume you mean that 5+ would raise eyebrows in a good way?

I think technical skills are in high demand, from what I see around Belgium/NL/German/Switzerland.

hey European hivemind, I need some help...PhD students here, especially foreign ones, are feeling a lot of concern related to evolving immigration restrictions here. Those students are increasingly looking to postdocs in EU. To help advise them better, what are expectations for postdocs?

How many suspicious patterns can you find in this table?

Hints in next post! 👇

Table 4 from Attar, Armin, et al. "Effect of once versus twice intracoronary injection of allogeneic-derived mesenchymal stromal cells after acute myocardial infarction: BOOSTER-TAHA7 randomized clinical trial." Stem Cell Research & Therapy 14.1 (2023): 264.

Standards are nowhere near as universal as the cohen ones. The {effectsize} R package collects and implements guidelines for interpretation, it’s a good go-to for a standard with references. I don’t know if my comment is in compliance with it. But the effect sizes are substantively very large.

Ian Hussey @ianhussey.mmmdata.io · 4d

More than 18 months have passed since I contacted the authors of this meta-analysis about serious flaws that substantially change the results.

More than 6 have passed since the published was involved.

No action taken.

One of the component studies has since been retracted.

There are discrepancies between Table 3 and Table 4.

If you recalculate from Table 3, the primary outcome is Cohen's d = 21 (!)

Ian Hussey @ianhussey.mmmdata.io · 5d

Seems like they have a mix of SDs and SEs

Ian Hussey @ianhussey.mmmdata.io · 5d

Perhaps there are other inconsistencies - I only looked at PSS at post.

Ian Hussey @ianhussey.mmmdata.io · 5d

My calculator takes rounding into account and lets you explore if SE has been confused for SE - I think that’s likely here. It still comes out as d = 3.7 if you assume they are SEs though.

Seems like there are inconsistencies in the summary stats repeated between Table 3 and Table 4. I think you’ve used those from table 4. When I use those from table 3 I get cohens d of about 21 (!)

“These findings provide clear evidence that data collected on MTurk simply cannot be trusted.”

Ian Hussey @ianhussey.mmmdata.io · 6d

You have huge signal boosting power, and I think that comes with the responsibility not to contribute to misunderstanding in this space. Every existing critique of this literature emphasises that causal claims are routinely made with weak or no causal evidence. Let’s learn from that.

Ian Hussey @ianhussey.mmmdata.io · 6d

I think you’re missing my point. We can’t squeeze causal claims out of longitudinal data, only inject causal assumptions. What we as readers can do is not repeat these causal statements as if they’re evidenced rather than assumed.

First MEP report.

Medical research often uses non-parametric tests. We looked, and noticed that small-sample rank-based tests (i.e. M-W, Wilcoxon) have significant granularity... like p-values!

So, here's GRIM for U values -- GRIM-U.

Enjoy.

Surely our job is to critically evaluate research, not merely repeat authors' talking points.

Your opening tweet is a clearly causal claim that you've repeated, which immediately doesn't stand up to scrutiny. This is a ubiquitous critique of this type of work.

This hasn't received much attention, but it looks like scammers also hacked into Francesca Gino's MTurk account, and asked MTurkers to buy her book Rebel Talent to boost the first-week sales of the book.

Poor lady cannot catch a break.

How long should it take to retract a paper with incontrovertible signs of data fabrication? Sleuths think 2 months is too long, particularly when clinical risks are involved. deevybee.blogspot.com/2026/01/an-o...

so maybe @mdpiopenaccess.bsky.social could make a resolution to remove all editors and reviewers who have accepted nonsensical papers. It would be quite a cull
