> For example, calling "how long do mice swim before giving up if you chuck them into a tank of water" is roughly equated to "amount of depression" (this is oversimplified a bit; you correlate a bunch of those measures etc. but still a lot of very weak signals).
Do I understand this? A purely reductionist view of my understanding: this is quantified as "the amount of will to live"? If my understanding is proper, how do you measure this without killing people? I grok that it is an extreme example, I am attempting to glean applicability of such an experiment to humans.
> And even the human black-box stuff in the DSM manuals admits a lot of different subtypes, lots of different and sometimes opposite symptom clusters, etc. It is entirely possible that mechanistically "depression" is a diverse group of mechanisms all boxed up into the most familiar mainstream concept/word.
Totally unrelated, but wife is an LCSW and I've glanced at the DSM. I've become convinced that book is near entirely for insurance purposes, similar to the ICD-10.
ICD-10: W220.2XD: Walked into lamppost, subsequent encounter.
