Wow, the pattern seems to be, in decreasing order, NT, then NF, then ST, then SF. That by itself isn't surprising given the nature of HN, but what is surprising is that each of the 4 groups are grouped off perfectly. I wonder if it'll be the same this time around (my guess is no because it was probably a coincidence). Isn't there a name for the psychological bias where the results get screwed around if you know in advance what it should be?

not unexpected results for hn but the NT groups are supposed to be the least common in the general population less than 4% if I recall.
