I got INTp, meaning I owuld be Ni-Te-Fi-Se (or are the tert and inferior reversed?) :s

I am quite sure that's not true, no way am I Ni-Te-Fi. Definitely Ti-Ne-Si-Fe.

It was a nice test though, I would enjoy seeing the percentages.

Perhaps if we take it in isolation from the socionics fucntion theory, it's better (as it was testing P/J behaviour nad not the functions, in which case it was correct).
