#ManyLanguagesChallengeOfTheMonth Citation practices suffer from systemic biases that can distort the academic record. Researchers often rely on a narrow canon of highly cited publications as cognitive shortcuts for identifying authoritative work, a phenomenon related to the Matthew Effect.

A two-dimensional scatterplot showing a three-cluster solution.

Caption: "Figure 2: A visualisation of a Latent Profile Analysis fit. Such visualisations may help readers appreciate that the clusters aren’t nicely separated and that the researchers’ notion of clusters may not correspond to their own."Table of contents:

Refresher: What is cluster analysis?
What are the clusters for?
What clusters, exactly?
Does the pipeline work?
What does the solution look like?
When running follow-up analyses, how is the uncertainty in the cluster assignments taken into account?
Was it worth it?

Big Team Science for language science: opportunities and challenges
Abstract: The present paper advocates for incorporating Big Team Science practices into the language sciences. Big Team Science is a promising mode of collaborative research in which top-down coordination directs efforts by a large number of researchers from different institutions towards a common scientific goal. The redistribution of resources and division of labor enabled by Big Team Science may enable researchers to increase methodological rigor, systematically explore claims across a wider sample of languages, and to diversify both the languages studied and the researchers engaged. However, implementing Big Team Science practices is not without challenges, some of which are unique to the language sciences. We suggest strategies and best practices for adapting to these challenges, including theoretical and methodological pluralism, variation in conditions among data collection sites, and navigating a trade-off between maximizing methodological rigor and ability to engage with the most inclusive, typologically broad language samples.

OSF is an example of how saving money by not dedicating more time for a UX designer nukes the product. I find it *unusable* (!) I would say, look into industry to learn a lesson, but alas, many start-ups put developers on a pedestal while utterly undervaluing UX design.

A thing that professionals in industry do, does not work well with academics in my experience: Using PM tools for task tracking. People seem so tool-fatigued that nobody uses the tool. I've heard from some that they had success with Trello, Miro and co, so I wonder what they did differently.

I'm sorry, what? In writing my first monograph, I spent six weeks trying to track down a citation in TWO languages I didn't know. And good thing too, because the citation was wrong. That's scholarship. That's research. You know, the thing we're trained to do?!?
The reactions of some researchers on Twitter finally being held responsible for not having read the very paper they submitted are... something. Mainly, they don't think they should have to check every citation or make sure the data is real and accurate. Because it's too hard, I guess.
