I don’t know if I’m on the spectrum or not, but I always focus on the details (if not ignoring the ads completely), because my first question is always, “how are they trying to fuck me this time?” The more obvious the emotional appeals and other tricks, the more I think they’re trying to screw people. If they are too over the top I write them off completely without even looking any further into it. If if they have to use that much manipulation, the product probably sucks.
I had a lot of math problems in school that were all about ignoring all the superfluous information to pick out what was needed to answer the actual question. I’m sure stuff like that helped too.
