Well, the problem with this line of thinking is that we do have empirical evidence that depressed people DO get better by making a huge effort to get better.
Drag had anecdotal evidence, which is incredibly weak evidence.
Drag may have had baseless belief in something and it worked out, but my point is, the evidence WAS available to support that point.
Drag doesn’t have to explain depression to me.
If Drag understood the evidence, then it sounds like the conclusion Drag should come to is not to baselessly believe in things without evidence, but rather to make a better use of context to rid dragself of blindness caused by anecdotal evidence.
