These are good points and good techniques IMO, and to add on–
Humans have always been drowning in the unknown, hence our chronic set of coping mechanisms, but on top of that, in this high-tech information civilisation we currently live in, now we’re drowning in information, as well. Which leads to some big problems, of course.
As in-- it takes considerable effort, honesty and openness to form a decent perspective on most subjects these days, particularly significant ones, and because of that hurdle, I fear that most people (you, I, everyone) are inclined to ‘settle’ for flawed understandings of topics, even with best intentions. Or at worst, some of us form whatever ludicrous opinions simply because it makes us feel better / at peace / self-righteous.
Point is-- it seems like the world just has way too much information for people to handle these days, effectively worsening our collective mental health and communal behavior, one might say.
