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 🧵

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. Regulate the platforms instead, for everybody.

If our theories have to do with people's daily experience then we really need to know how well we're measuring daily experience. So we need more of what Kevin's team is doing here! Just because your item has the right words in it doesn't mean you know what it measures, or how well.

Most of psychotherapy research is progress, not innovation. This review concludes that small, incremental benefits can arise from it: - Digital tools can increase access and engagement. - Personalization can improve response rates. - Simplified, scalable formats can reach more people.

The three "waves" of psychotherapy are often described as historical fact, which is astonishing when you consider that they represent the distorted and sometimes straight up incorrect view of a single individual (Hayes).
