Yes, I deleted all my comments here (under another username), due to the ridiculous responses that it prompted. Sure, I have some personal experience of depression -- both myself and family members. However there is also a lot of evidence behind what I'm saying, namely:
- situational depression, which -- as it's title says -- is in fact in response to situations.
- situational depression (e.g. bereavement) has been shown to meet all the criteria of clinical/major depression in many cases.
My hypothesis simply involved making a small (in my opinion) logical jump to offer a possible explanation for why situational depression exists. Given that the article itself mentioned a number of theories for the evolutionary role of depression, I didn't think mentioning my own theory would start such a firestorm. I think it is logically tenable.
What is the reason for the hostility? Are we supposed to write peer-reviewed comments for HN? Is it just that many HN posters exhibit excessive negativity and mispaced arrogance? I've certainly seen a lot of negativity and mispaced arrogance in the past on HN, and a number of times it has made me reconsider whether or not I want to be part of this community. This time I'm getting closer to that decision.
It could also be depression itself. As others have noted, sometimes it isn't necessarily the situation that is the problem, but your reaction to events (this is what CBT aims to fix). Perhaps the excessive negativity in HN is what is causing/exacerbating some people's depression?
Anyway, I'm not really interested in interacting with idiots (and I'm not referring to you here, javert) who downvote and are overly hostile when people like me share their personal experiences and make general comments on science without posting a frickin peer reviewed paper. Feck that...
