Ha, good point, and for the record I'm happy to read your stuff here (though I've read quite a bit on Psych Central in the past).
I'm not someone who could tell you for $100 what impression the posture gives, but I think that makes me better at staring at her neck and guessing that she probably gets temporal headaches. (That she may well call "migraines" and would be caused by SCM insights.)
My impression is that this is the stereotype of what we consider good posture 😹 Thanks for the nice article! (For the record, you'll see people with good posture in the sports of CrossFit and gymnastics.)
