I can resonate with this, and I see it in a lot of NFs (not all) and a lot of higher Fe types (not all).

I'm wondering if it's a combination of type, natural empathic abilities, and conditioning from childhood. Being raised in an abusive or emotionally unstable environment develops the ability to read micro-expressions and be hyper attuned to a caregiver's state as a survival mechanism, even more so in someone who is already naturally empathic or observant.
