I remember reading about some research into the reading of facial expressions when people were wearing masks prior to COVID. Basically, it dulls down positive emotion recognition and amplifies negative emotion recognition. People who were smiling were perceived as angry for instance.
That article/ paper seems to have been buried in an avalanche of COVID mask propaganda.
I did find this recent one though: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0249792
