I heard an interview with Ariely about dentists. The results seemed surprising. I couldn't find a published study & then read follow-ups from the data source saying he didn't even have access to the data he claimed to have. The only thing that mildly shocks me is the lack of consequences for decades

Excellent opportunity for early stage clinician-scientists. You do some research at the NIH and leave with funding for 5 years after, like a K99/R00 for MD's but you get to do research at the largest research-only hospital in the world. IMO better if you love zebrafish 😘 www.nih.gov/research-tra...

Substantial improvements in research interpretability & reproducibility are often hard. Sometimes the improvements are easy. (The underlying idea is older & easy, but convincing people is sometimes the hard part) I'm happy to have contributed to this easy and now widely accessible improvement.

Psychological Science special issue call 📣 Ever had your research denigrated bc it's "only descriptive", "what's the mechanism though?" and "but what are the theoretical implications?" Now has come your time to shine. Send your best descriptive work! www.psychologicalscience.org/publications...
Psychological Science invites submissions that advance psychological science through careful description of psychological phenomena. Psychological research often focuses on explaining and predicting phenomena before we have a sufficiently detailed understanding of them. It can be difficult to build strong theories on incomplete empirical foundations of the phenomena themselves. Careful descriptive research helps establish shared empirical reference points developed around well-characterized phenomena. As such, descriptive research contributes to psychological science both by improving our understanding of the phenomena themselves and by providing a stronger foundation for future theory-building, explanation, and prediction.

We are interested in manuscripts that:

Deepen our understanding of psychological phenomena, including what they look like, how they vary, and how they unfold;
Draw on a variety of sources of evidence and methods, including qualitative, quantitative, and mixed-methods approaches; research conducted in naturalistic settings; intensive, longitudinal, or small-sample designs; and open or large-scale datasets; 
Provide necessary context for interpreting what is being described, including who is represented in the data, the settings and circumstances in which phenomena occur, and the broader social contexts in which they are situated; and/or
Make a substantive contribution to psychological science through the quality, depth, or significance of the description provided.
The deadline for submitting regular manuscripts is April 15, 2027. Registered Reports will also be considered. The deadline for submitting Stage 1 Registered Reports is November 15, 2026. Authors should indicate in the “Comments to Editor” box during submission that the manuscript is intended for the “Descriptive Research in Psychological Science” special issue.

I have been meaning to write a post about a preprint that I'm pretty excited about: www.biorxiv.org/content/10.6... In neuroscience we often assume that we can learn something general about “the brain” using different species. But is this true? Do monkeys even see the world the way we do?

I skew towards keeping mistakes in the scientific literature because identifying & correcting mistakes is part of healthy scientific discourse, but a core finding that rests on clearly wrong data (papers that had references, but were logged as not having references) feels retraction-worthy.

This gives a bunch of problems that boil down to AI is swamping peer review because people are fraudulently passing off AI text as their own scientific output. For all the weaknesses of peer review, a solution that pushes for more AI without addressing AI-facilitated fraud is fundamentally unserious

Just heard a term to complement p-hacking: RGB-hacking. p-hacking tweaks analyses to get results below a desired thresh & RBG-hacking tweaks the colormap & scale. + vals pop more with this colormap. Not calling out the source because I could easily find another & this can be done without ill intent.
A colorbar from -99.5 to +99.5 that goes from black->purple->green->yellow->orange->red but with uneven spacing between colors so that positive changes pop more and even positive changes close to zero pop more than negative changes close to zero.

How do we define "good" fMRI data? Especially with resting state, there are circularity risks if we evaluate data quality as showing the networks we expect to see. Javier Gonzalez-Castillo (& me & others) developed pBOLD, a new metric that uses multi-echo info. www.biorxiv.org/content/10.6... 1/8

Five years ago, I had a very sick child and referrals to several pediatric medical specialists and tests in a building a few blocks from the US Capitol. The kid got a diagnosis. Treatment worked. But for me, January 6, 2020 means memories of rescheduling medical appointments for a very sick child.

So I made a little simulation where there is no actual discordance, i.e. the underlying values from which the CBF, CBV, BOLD, and T2* are measured all move in lockstep. With zero noise this gives you zero discordant voxels (nice little diagonal line).
