According to Leander et al. (2012):
“In three studies, we found that people literally feel colder in response to inappropriate amounts of behavioral mimicry”
“There exist implicit standards for how much nonverbal behavioral mimicry is appropriate in various types of social interactions”
So, how much is too much?
“Our results also highlight the importance of (implicitly) knowing when to mimic other people and when it is okay to be mimicked by them…”
In other words: it depends on the situation and you have to trust your instincts, but be aware that blanket mirroring of other people’s body language can come across as plain weird. People who mimic body language indiscriminately literally give us chills.
