They just seem so...blunt, unrealistic.
There's a fine idea going on in the theory itself. Two people valuing similar functions help each other to prosper and grow. The weak function can count on their partner's strengths and and vice versa. The two don't devalue each other because they know they need wha the other partner have. But... looking at it more realistically.

How can for example an ILI ever meet an SEE. SEEs are stereotypically the adventurous, party loving extroverts. ILIs are analytical, deep and intelligent beings who enjoy their alone time to think and to recharge. I just don't see how this is supposed to work.
Another example IEIs and SLEs. they both value Se and Ti, Ni and Fe. SLE's Ni is weak, IEI's Se is weak. Now imagine a football player going to the quiet girl in the corner who just finishes her poem for the creative writing class when he suddenly starts to talk about how he scored zillion and one on the game and then talks about football rules and buddies from the team. What is the poor girl supposed to do, when she's interested in art and poetry and doesn't give a damn about his football game?
Those are just few examples, but looking at it realistically. I can hardly imagine an artistic senstive people grouping up with impulsive sportmen, or analytcal educated men hooking up with the "live of the party" girls.


So...how is this suppoused to work?...In real life?
