Subtype matching or not in duality and activity

[Kill4Me]

Yes. It's called Advanced Duality. Advanced duality is an exclusive find by Socionics New Wave. (Of course, the credit really begins with the pioneers of subtypes and dualization. My find is additive.)

Note that for each socionics type on my socionics type list one subtype has a positive charge and the other subtype has a negative charge. So as to avoid confusion with the positive/negative dichotomy in reinin, just call it a light/dark split (or +/-).

Let's take SLE and IEI, both duals. SLE-Ti is the negatively charged subtype and SLE-Se is the positively charged SLE subtype. IEI-Fe is the positively charged IEI subtype and IEI-Ni is the negatively charged IEI subtype. It's best to match up with your oppositely charged dual, though it may be much funner for a - (minus) subtype to hook up with another - (minus) subtype.

But for long term, SLE-Ti dualizes better with IEI-Fe, and SLE-Se dualizes better with IEI-Ni.
