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 🧵

I've been noticing that “cross-sectional” has become shorthand for “methodologically weak” in (network) research, and often data being cross-sectional is treated as a methodological objection in itself. I took some time to put my thoughts down in writing. Pre-print: osf.io/preprints/ps... 🧵⬇️

New preprint! Psychometric networks are often summarized with centrality indices that are sometimes useful and other times not. We show that the "most central" node's influence depends heavily on the configuration of edges in the network; its degree distribution. osf.io/preprints/ps...

🌟 NEW PRE-PRINT! 🌟 “It seems that everyone has got something”: A qualitative study of adolescents’ attitudes towards self-diagnosing with mental health problems from me and @nhigsonsweeney.bsky.social osf.io/preprints/ps...
AbstractBackground:There is growing concern about adolescents self-diagnosing with mental health problems, with potential links to increased mental health awareness efforts and social media. However, little is known about adolescents’ attitudes towards self-diagnosis, including why they think it happensand potential consequences.Methods:We conducted online semi-structured interviews with 24 UK school-aged adolescents (13-to 17-years-old)recruited from four schools. Data wasanalysed using reflexive thematic analysis.Results:Four themes were generated. Acceptable versus unacceptable motives for self-diagnosishighlights the different reasons adolescents perceived to driveself-diagnosis, which were given a value judgement. Self-diagnosis was more acceptable when carefully researched and used for self-understanding or help-seeking, andless acceptable when used superficially to seek attention or excuse bad behaviour. Rules for determining (in)authenticityexplores the implicit criteria adolescents set for judging the credibility of someone’s self-diagnosis, including openness, severity, and gender. Self-diagnosis is the only viable route to supportencompasses adolescents’ belief that self-diagnosis is understandable given the current inaccessibilityof healthcare systems, providingaccess to informal sources of emotional, practical, and social support. Finally, modern adolescence is fertile ground for self-diagnosisdiscusses how the current context of adolescence, including social media and the widespread use of diagnostic language, facilitates self-diagnosis. Conclusions:School-aged adolescents view self-diagnosis as an understandable yet potentially problematic practice. While it may be a pragmatic response to inaccessible services, adolescents are concerned about the impact of inaccuracy. Improving access to timely mental health support and promoting balanced information may reduce reliance on self-diagnosisNote: This version of the article is a pre-print and has not been peer-reviewed.

The distinction between grassroots activism and automated influence is collapsing. We typically worry about "bot farms" or "troll factories." But a distinct, more complex threat is emerging. We call it "Cyborg Propaganda."
The Matrix of Coordinated Influence. Traditional frameworks for analyzing online influence focus on the distinction between human and automated actors (Identity Axis) or between spontaneous and coordinated behavior (Articulation Axis). Bot Nets (top-left) rely on synthetic identities and automated scripts. Troll Farms (bottom-left) use human operators to manage fake personas. Grassroots Action (bottom-right) involves verified citizens sharing self-authored views. Cyborg Propaganda (top-right) represents a new paradigm: verified human users disseminating centrally generated, algorithmically generated narratives, effectively ‘hybridizing’ the authenticity of the grassroots with the scale of the botnet.
