Of course you can disagree with me, but this is what all my experience with Socionics has led me to believe.

There is, e.g. for an IEE, no necessity for Ne and Fi to exchange information. Ne and Si serve, in the IEE-SLI dual relationship to establish a foundation for the relationship to exist and the individuals in this relationship to feel safe and secure. Once established, and only then, can Fi and Te be used to help the other person out.

We can see this in semi-dual relationships: they are easily established, but useless to get further in life.
