Meeting DSM-IV diagnostic criteria

You might be interested in operationalization. Every measurement is also an operationalization - even things like temperature, speed, and weight.

Eliding or obscuring the act of operationalization leads to reification - treating concepts like real tangible things. I wish reification was taken as seriously as our taboo of anthropomorphization. It happens way more, and sneakily smuggles in human values into the sciences. In some ways it's unavoidable, but being opaque about it and doing it without knowing is a sin.
