Earlier quoted context omitted.
That assumes people aren’t induced towards self harm due to an increased awareness? If you believe suicide or self harm are common (and valid/acceptable) solutions to your issue, would you not be more likely to do so?
Isn’t this just the argument that it’s a social contagion ? And indeed, if you can be convinced those are the solutions to your problems, surely you can be convinced you have problems in the first place as well?
Instead think of social contagion as an additive/multiplicative factor that we don't know the value of.
So imagine a world where we're not allowed to talk about or problems. In that world you'll have your base measured rate X. Then you add a new stressor and get your increase over X.
In a model with social contagion you still have X, you still have your increase in your stressors, then you have the confounding factor of the social contagion.
