>>14303541Unironic actually serious answer:
It's a mix of my own research capabilities (I'm a PhD in Chemistry with a statistics background), expert opinions on some matters, intuition (sometimes even guesswork), talking to peers, etc. There is no one method that will work for everything because sometimes we have missing information. I also constantly try to check if I could be falling prey to common cognitive biases, and I study them in depth because I believe they are the root cause of a lot of issues at the personal and societal level.
Anyone that claims to have found the utmost solution to all problems, in my opinion, is trying to sell you some product for their benefit, not to your benefit. OP's picture is a prime example. They give you no guarantee that their "high T/autist (KEK at that conflation, autists are way over-represented in the transgender department) judgement is above groupthink, and ask you to just blindly believe it.
If you can verify something empirically for yourself with direct access to tools and resources, that's a completely different situation from just trying to vaguely conclude things from third hand accounts with data that is not accessible anymore to anyone. Don't be a retard, don't treat every situation like it's the same, and especially don't be as retarded as the OP pic (unless you like sucking cocks as much as he does).
