That's an interesting question. There are so many interesting meta-level details like that of how gender identity ideology has become pervasive in our culture and affected us. I think my "trans radar" has gotten better, too, although perhaps not as sharp as yours.

I think it's a natural consequence of finding out that people are trying to lie to you in a certain way, and then being more on the lookout in the future for that type of lie. Like having someone try to scam you, and then learning more about that type of scam afterwards, and being much quicker to catch on the next time it happens.
