Sticking a label on something — even if it enables you to categorize it as being akin to a large batch of other ‘somethings’ to which you have given the same label — is not the same thing as understanding or explaining something.
Medical and para-medical professionals may be decently aware of that, but the average person, IMHO, is not. Person goes to the doctor with a complaint of a sore red throat. Doctor writes down “pharyngitis”. Person goes home and tells family “The doctor figured out what’s wrong with my throat! I’ve got pharyngitis, that’s what’s causing my throat to be sore! And I got these pills to fix it!” Doctor did nothing of the sort. Pharyngitis is just another way of saying “sore red throat”. Nothing has been explained. And the pills are not specific to some tightly defined bacterial or viral agent, you know, pharyngococcus Strain L-14, but rather generic remedies for sore throats and/or broad-spectrum “attack any infectious bacteria that might conceivably be causing this” pills that are not at all tailored to the specific problem at hand.
In no subcategory of medical practice is this more strongly manifest than in the mental health professions. People really really want to believe that there is a well-understood narrowly defined set of psychiatric ailments for which we know the etiology, the likely trajectory, and the perfectly tailored intervention.
In reality, most of the diagnoses are on the level of specificity of “pharyngitis” and the available remedies are broad clumsy things. If you replaced all psychiatric services with the following automatic one-size-fits-all approach, you’d scarcely be able to observe a difference:
• If person has not done anything dangerous or socially disruptive, has not threatened to do so, and you have no strong gut feeling they will despite lack of concrete evidence, require them to talk to you on a reg basis and keep them under observation but don’t do anything yet; otherwise proceed directly to steps below. If during talk or observation you perceive sufficient reason, also proceed to steps below.
• Drug person up to make it less likely that they will do dangerous or disruptive things.
• If drugged person is still dangerous or disruptive, increase dose and/or try short-term incarceration in an isolated environment.
• If that doesn’t work, just keep them incarcerated.
Lest I be misconstrued, I am not recommending this as an ideal approach. I’m saying this is the approach, shown here without the shiny spraypaint coating.
