so they gave a depressing scenario to people and the depressives were quicker to identify that it was, in fact, a depressing situation.
however, put depressives into a fun party where people are open and accepting and the depressives will often instead focus on a negative, antisocial view that is manufactured by their mood disorder and takes them out of this very welcoming and positive situation.
As a lifelong depressive I've struggled to see reality for what it is and not as what my depression is constantly misrepresenting. I of course also have the experience where I can see an actually depressing situation for what it is more readily than others, but I think the premise of the article is still generally absurd. The world seems like a very hostile and dangerous place to me, and while you can of course find limitless examples of this being completely true, it nonetheless it prevents me from doing things that other people do quite safely and successfully all the time and for which this dark perspective is completely exaggerative and distorting.
