What we know
Adolescent peer relations are transformed by quantifiability, publicness and permanence. Some self-harm communities show reinforcement of harmful norms alongside support.
Social reinforcement
A like is a social fact. It is not a diagnosis.
Platforms quantify response. That can reinforce posting. Whether it changes symptom interpretation, expression, or severity is a different, mostly unanswered, set of questions.
How we know it
Affordances theory; dual-effects internet/self-harm reviews. Direct tests of metric reinforcement of psychiatric identity are scarce.
What else could explain it
People post more because speech is now allowed, not because metrics trained them. Supportive comments improve coping.
What we don't know yet
Which outcome moves: posting behaviour, interpretation, expression, or severity.
The model under investigation
Symptom-related post → social response → reinforcement → future posting behaviour → community feedback.
Likes, comments, followers, shares, views, validation, community status, belonging, attention, and creator incentives are different reinforcers. A private Discord role is not a public view count. Research that collapses them will mislead.
Four outcomes that must not be merged
- Posting behaviour — more videos, more tags, more disclosure.
- Symptom interpretation — the same bodily or affective events recoded.
- Symptom expression — what is displayed or described to others.
- Symptom severity — the underlying difficulty, independently assessed.
It is easy to observe (1) and infer (4). That inference is the error this page exists to block. Self-harm research is the closest analogue that even tries to speak to (3) and (4), and even there designs are constrained and mixed (Marchant et al., 2017; Arendt et al., 2019).
Language
“Attention seeking,” as a casual description of patients or users, is not used here. Attention is a human need and a platform currency. Reinforcement can occur without a cynical motive. Where commentary uses “performative mental illness,” it is treated as a claim to test, not a finding to repeat.
