What we know
There is a shared trunk: content enters ranking systems that can repeat related items. Downstream branches are not equally evidenced.
The core model
Five pathways from content to consequence
Mental-health content can be recommended, repeated, and taken up in more than one way. Click each arrow. Solid lines are empirically discussable. Dashed lines are hypothesized.
How we know it
Each arrow is tied to structured claims and papers. Hypothetical arrows are dashed by design.
What else could explain it
Selection can mimic a pathway: people already looking for answers get more of the same.
What we don't know yet
The causal status of Paths C, D and E at population level.
Shared trunk
Mental-health content
Videos, posts, infographics, creator narratives, and peer testimony about symptoms, diagnoses, and recovery.
Shared trunk
Algorithmic recommendation
Ranking systems that predict what will hold attention and therefore what is shown next.
Shared trunk
Repeated exposure
The same themes, labels, and symptom models returning across sessions, not a single encounter.
Path A
Recognition → care
Content helps people recognize genuine symptoms, improve literacy, seek assessment, and obtain support.

Symptom recognition
Mental-health literacy
Professional assessment
Treatment / support
end of path A
Path B
Self-diagnosis → support
Recognition leads to self-diagnosis, peer community, reduced stigma, and improved coping—even without, or before, clinical diagnosis.
Symptom recognition
Self-diagnosis
Community support
Reduced stigma
Improved coping
end of path B
Path C
Attention → identity
Repeated exposure heightens symptom attention, recodes ambiguous experience, and integrates a label into identity.
Repeated exposure
Heightened symptom attention
Reinterpretation
Self-labelling
Identity integration
end of path C
Path D
Reinforcement loop
Self-labelling leads to community membership, social reinforcement, and possible increases in symptom signalling, which may loop.
Self-labelling
Community membership
Social reinforcement
Symptom signalling / expression
Possible reinforcement loop
end of path D
Path E
Functional presentation
Exposure contributes, in susceptible people and particular conditions, to functional or socially mediated symptoms that then present clinically.
Repeated exposure
Functional / socially mediated symptoms
Clinical presentation
end of path E
