I recognize that my intrusive thoughts are my own, but this term existing is helpful because: 1) some people incorrectly believe that thoughts imply a desired outcome, and this term helps explain and describe that this isn’t always the case and 2) it’s a meaningful and useful way of categorizing these types of thoughts for the purposes of psychology, psychiatry, understanding ourselves better, etc.
In cases like severe OCD, classifying intrusive thoughts as such could help someone understand and cope with disturbing thoughts and develop subsequent coping mechanisms. Not everyone’s the same and some terms can be helpful.
Like most popular social media sites, you usually won’t see very valuable discussion in the comments, at least in my experience. It’s mostly for people to post news, research, and so on, and follow the big names or organizations in their field.
Most of the valuable information is diffused via posts but I do put a bit of time and effort into trying to filter out all the crap posts like memes, the faux inspirational stuff, self-aggrandizing nonsense, etc.
