There are myriad claims on social media that are justified by the author observing (or being a self-proclaimed expert in) “body language.” I have always thought this was ridiculous, sort of a faux psychological claim of expertise. Of course, the French have longed studied graphology (handwriting) to determine behavioral traits (hard in a world forsaking cursive), and scapulimancy, the study of old animal shoulder bones, has been used by various cultures to contact the gods.

“Body language” is a similar myth. You don't believe me, here's what Psychology Today has to say about it:

“Every day, we get queries from around the world about nonverbals and invariably about detecting deception through body language. The biggest takeaway from the hundreds of messages is that despite the undeniable importance of nonverbal communication, many myths and false beliefs undermine its importance, relevance, or utility. So, we decided to pool our resources and comment on ten myths about body language that are currently trending, and you may notice some have been trending for a long time.” (https://www.psychologytoday.com/us/blog/spycatcher/202207/debunking-body-language-myths)

But why trust me or science? After all, who knows what my body language looks like right now?
