I find it hard to believe our group compromises only 2% of results.
I've read before that the "NT" combo is really rare (my dad, brother, and myself all often score it). Most people wired for logic over emotion (T) are also wired for the current reality vs. theoretically possible (S), which makes sense.
By the same token, most people who are really into theoretical possibility are probably more likely to be emotionally driven than logically.
