My paper on concerns about replicability, theorizing, relevance, generalizability, and methodology across 2 crises is now in press at the International Review of Social Psychology. After revisions it was 17500 words, so it is split in 2 parts: osf.io/dtvs7_v2 and osf.io/g6kja_v1
My colleague Krist Vaessen wrote a new book: “Neomania: How our obsession with innovation is failing science, and how to restore trust”. It's a great analysis how the drive for novelty hinders reliable scientific progress. Open Access, so read it here: books.openbookpublishers.com/10.11647/obp...

Indeed, it is perhaps surprising this has not been pointed out, but as far as I know, qualitative research is among the most replicable research areas in science. Or at least, all the replication studies I have seen are basically successful replications. It might not be 100%, but it is high!
Note that this in itself is a well-replicated finding. At least a dozen studies show that when researchers replicate qualitative research, or re-analyze it, they come to basically identical themes. There is nothing special about qualitative research with respect to replicability.
This is a great qualitative research paper. It sheds light on questionable research practices. But more importantly it demonstrates direct replications in qualitative research work as you would expect: independent teams reach basically the same conclusions royalsocietypublishing.org/rsos/article...

One way to fix the system is to stop submitting low quality work. If your papers are regularly rejected after full review (ignoring desk-rejections) they are of too low for where you are submitting. Work should rarely be rejected after review by peers. If it is, you are doing something wrong.
In the last ten days, I agreed to review 6 manuscripts and declined 5 other. As an editor, I tried not to review more than 2-3 manuscripts a month. Now that I’m on the other side, the enormous challenge in securing reviewers is top of mind. On both sides, it’s clear that the system is very broken.

There are so many folks who submit, submit, submit, and always decline reviews. Happy to use the resources for their own gain but unwilling to put in effort themselves. This seems like at least a partially solvable problem.

Dunnette, 1966, on our tendency to bury negative results to make our research look better than it is. In 2026, this is a violation of the code of conduct for research integrity in my country, yet it is still common practice. One can only wonder what is needed to finally change this.

Most researchers are unaware that the concerns about strength of theories, methodology, and lack of generalizability led to a crisis in the 60's and 70's as well. Nothing changed then, and history is a good teacher for why nothing is likely to change this time around doi.org/10.5334/irsp...

Hypothetically, the greatest test of an academic’s commitment to the freedom of knowledge is to ask them to sign a pirated pdf of their book.
This is a hypothetical test I have devised and never ever used.

Every now again it’s useful to repeat advice about accessing papers that are behind a paywall that excludes you. Email the author. My estimate is that 90% of academics are so thrilled that a living, breathing, possibly even reading, person shows interest that they will swiftly send you a copy.

It's a beautiful plot, but it's terribly misleading about the impact of pre-registration. More recent studies (with higher sample sizes) find very little impact of pre-registration on the publication of null results.

Awesome to see more journals promote replication studies. They are an essential but too rare part of scientific discovery. If an effect can't be intersubjectively established, we do not understand it well enough to consider it scientific knowledge.
New submission format at SBE:
“Replications as Registered Reports”
link.springer.com/journal/1118...
You can get "in-principle acceptance" before data collection even begins; final paper gets published regardless the results, if the study is conducted rigorously.
