I'm sceptical about the natural/learned distinction. My observation is that any very socially adept adult has spent a great deal of time and effort learning these things, thinking about them, and deliberately applying their knowledge, however easily it may have come to them in childhood. In fact, the most pressing task of adulthood is to relearn properly all the stuff you learned in childhood and didn't realise you were learning.

Here's an analogy: making music. Some people take to it easily, but if they don't practice and study and practice and study for years, they'll never be anything special.
