Tired of the centrality debate?
Of seeing one application where centrality is influential & others where it's more arbitrary?
We have the article for you:
osf.io/preprints/ps...
Turns out centrality can indeed matter; but when it does depends on underlying network structure & mechanism of spread 🧵

This...the fetishizing of unreplicable neuroscience in order to legitimize our work is self-defeating. We don't need to know that depression is in the brain (as opposed to what???) to know it is problematic. How much money have we wasted proving something like depression is "real"?
Hey psychologists, when you're explaining some psychological phenomenon that's perfectly well captured in psychological terms, maybe you don't need to refer to some shitty neuroimaging study with ten people to make it seem more "sciencey"...

New paper showing insufficient evidence for neuroimaging features to define reproducible, biologically valid, & clinically meaningful schizophrenia subtypes. The subtypes identified to date likely reflect continuous variation within the disorder rather than discrete, biologically distinct entities.
A review of 18 studies found no consistently reproducible subtypes of schizophrenia, suggesting that differences in brain structure across patients may reflect a spectrum rather than discrete biological categories.
Neuroimaging-Based Subgroups in Schizophrenia: A Critical Appraisal of Clustering Studies
Efforts to define biologically grounded subtypes of schizophrenia have increasingly leveraged neuroimaging data and clustering algorithms. Such approaches aim to capture patient-level heterogeneity…

If you truly believe that social media platforms are harmful places, the idea that the government now makes a list of vulnerable people and bans them from these platforms, e.g. based on age, is not a sensible or good faith solution.
