So, I've been wondering lately if flatness, deadpan, and monotone in voice and vocal inflection have any relationship to type, and specifically to NT's. It seems as though it is part of the NT stereotype, but I'm not sure if there's any truth to it.
So how about it? Do you know many NT's that speak that way? Do you know any that don't? What are the patterns that you've noticed with regards to these two categories?
