If the MBTI statistics are to be believed (http://www.statisticbrain.com/myers-briggs-statistics/) (I think the typings for the socionics ones were skewered by the Russian-socialist-equitarian mindset they originated from, to sell a false dream that "there's a dual for everyone!") Ni types make up less than 10% of the population, and Si/Ne types dwarf Se/Ni types. I think a lot of Ni "cranks" or "seers" just get frustrated because a lot of people have Ni in their unconscious and don't really understand what they are saying. So they give up until some sexy Se type starts treating them like a court magician or something lol. I admit (ashamedly), I've probably done the "arguing with myself in front of other people" thing before.
