I hate socionics

[Sol]

To do lesser of typing mistakes and to trust only to classical theory may help you to like it.

Socionics is for housewives and homosexuals and I'm not a housewive.

The main where it's useful is to make good pairs for long relations, as helps to take into account one of factors for friendship.
People without homosexuality have problems to make good pairs too - they often break and it's easy to find divorces %.
Housewives have much lesser of use, as they've made the choice of the pair already.

Also you may add points to have F type (more Fe).
