@Disturbed, I'm not a fan of Reinin dichotomies myself, and they're not common among socionists too, but in reality the differences are evident as the types can vary very much.

A LIE-NI doesn't become a ILI, but works following similar patterns, and his psychic stacking will be left unvaried in the order, so that both a LIE and a LIE-Ni will still aim at Fi, but a LIE more so, while a LIE-Ni will be more drawn to Se than a normal LIE would, and will be able to use Fi more too (contact functions are all boosted).
