Yea I know. I once went into MBTI in the vein of "it's not scientific but can I learn something useful out of it?" I tend to test close to ENFP/ENTP. I can notice tendencies of both in me. Then I went on the ENFP subreddit as I suspected many had ADHD and simply asked in a poll. A lot of them said that they did, as I suspected as I'm subclinical myself (and it becomes clinical real fast I even just sleep for 6 hours on one night).
So I learned that you can definitely glean some insights from it. One insight I have is: I'm a "talk out loud thinker". I don't really value that as an identity thing but it is definitely something I notice that I do. I also think a lot of things in my mind, but I tend to think out loud more than the average person.
So yea, that's how pseudo science can sometimes still lead to useful insights about one particular individual. Same thing with philosophy really, usually also not empirically tested (I do think it has a stronger academic grounding but to call philosophy a science is... a bit... tricky... in many cases. I think the common theme is that it's also usually not empirically grounded but still really useful).
LLMs make me think out loud way better.
Best rubber duck ever.
