What types do you find to be the most animated with their hands as they speak?

Um… every type hand talks, but I’m not sure I could say which does it the most.

I think there’s a lot of things at play, there, and I don’t think the main factors are mbti related.  For example:

Cultural element (are you an Italian hand-talker, or are you culturally more still/have more physical space boundaries).

Situational (are you excited or otherwise emotionally charged.  Note that some people hand-talk more when calm, others when nervous, and it changes again if you are nervous around friends or around strangers).

Upbringing/training (have you changed your gesturing because you have been taught to do so – politicians or actors for example, but generally just anyone having to be aware of how you are being perceived).

There are some hand related things that are mbti-oriented, though.  Extraverts are more likely to use both hands at once, while introverts are more likely to use one.  Js tend to beat a steady rhythm with their hands where Ps are more likely to flow with their thoughts. 

Most unconscious actions that tense muscles in a specific way will share some consistency across type.  When or how much they occur is a lot harder to pin to mbti type.
