These explain the difference entirely:
High and Low Context
Low context culture - Wikipedia, the free encyclopedia
High context culture - Wikipedia, the free encyclopedia
The many disputes we find on here, in my estimation, comes from an unreasonable expectation on the Fe/Ti side for the Fi/Te user to understand the context in which he or she is speaking, along with the inability of the Fi/Te user to understand that context without explicit description.
So, as far as type goes for fitting in to the spectrum, as far as I see it:
The more compatible your type is with the kind of culture you live in, the more likely you will be to engage in a leadership role. ENFJs are the natural leaders of highest context cultures, while ENTJs are the same of lowest context cultures. That shifts with the culture - so the US, a very low context culture, but not entirely so, values the leadership of ESTJs, while Iran, a much higher context culture, prefers the religious leadership of any of the xxFJ types.
Of course, your mileage may vary
