Let’s get negative about scholarly publishing | Reciprocal Space

Thank you Stephen Curry for your leadership on this exciting blog post and collaborative publication in @PLOSBIOLOGY on ending #publicationbias written after a workshop hosted by The National Institutes of Health. occamstypewriter.org/scurry/2025/...

Ending publication bias: A values-based approach to surface null and negative results Sharing knowledge is a fundamental principle within the scientific community, yet null and negative results are still being underreported. This Consensus View discusses the problem of such publication...

Null & negative results ≠ failure. They’re essential—but still sidelined.

Proud to co-author this @plosbiology.org paper tackling systemic bias & calling for culture change.

ECRs pay the highest price for this biased culture!

#GRADE provides guidance for rating #CertaintyofEvidence regarding accuracy of diagnostic tests. This informative paper provides details on assessing #inconsistency, #imprecision, #PublicationBias and other domains and for creating #SummaryofFindings tables.

Z-curve plot is a new visual model fit diagnostic for #metaanalysis with an emphasis on #publicationbias. In contrast to funnel plots, z-curve plots
- visualize the distribution of z-statistics (where bias usually occurs)
- compare the fit of multiple models simultaneously

#PublicationBias means #FST studies showing positive antidepressant effects were more likely to be published, while those showing no or negative effect likely weren’t.

This skews the literature, leading to artificially "inflated" results.

Does anyone know of a journal of null results (eg. www.jasnh.com) that accepts short articles / research notes?
Ideally, a couple of pages would be enough.

Although evidence for small-study & decline effects is widespread in ecology & evolution (doi.org/10.1186/s129...)

➡️ We did NOT find clear evidence of #publicationbias in our dataset.

👉 Presumably thanks to our efforts to obtain nonreported results directly from authors.

Which Trendy Teaching Techniques Actually Work? How many common teaching techniques have actually been tested? Of those that have been tested, what were the results? The answers may surprise you. They surprised this educator!

Some of my favorite #teaching methods were ineffective when tested.

So I listed ineffective and effective techniques (based on meta-analyses, etc.) and explained how #publicationBias and #conflictsOfInterest can cause overrated teaching trends.

Parents, educators, and students may be surprised!

Just make it stop! When will we say that further research isn I have a lifelong interest in laterality, which is a passion that few people share. Accordingly, I am grateful to René Westerhausen who ...

A small rant about zombie ideas and the tendency to keep looking for modifications of study methods to avoid concluding that a null result is really null. deevybee.blogspot.com/2024/03/just...
