^ OK, maybe you should read up a little more on Ni and Si, and just on functions in general, and see what fits and what doesn't...
PS: movies do kinda run on formulas

PS2: thought this might be sth to look into (Dichotomies):

EDIT: I find Positivist vs. Negativist *kinda* easy to pick up. ESTj is negativist, ENTj is positivist.
Positivists
- More inclined to optimize already functional systems of things and processes.
- "This glass is half-full", "We have already collected $438,000 for that project"
- Usually more complimenting than reprimanding.
- Socially and intellectually more trusting.
- Explains what things are (irrationals) or should be (rationals).
Negativists
- More inclined to solve problems in systems of things and processes.
- "This glass is half-empty", "We need $62,000 for that project"
- Usually more reprimanding than complimenting.
- Socially and intellectually more mistrusting.
- Explains what things are not (irrationals) or should not be (rationals).
EDIT2: forgot to mention it may not be a bad idea to read up on temperaments (EJ, EP, IJ, IP) in addition to above, in case you haven't done so already. cheers
