Always though ADHD was not about being able to have unbiased sense of a person. Instead much more about the inability to interact and be perceptive about the world and
persons around you.
I couldn’t read people in teens. In 20s I decided to change that. Would stare intently at a person face and watch every muscle movement, tone, etc. read some books on body language.
Was absurdly exhausting for me. But I got very good at reading people. Eventually it went from intense analytical analysis to just “normal” paying attention.
