Not going to say these are outright wrong or not helpful, but they're not necessarily accurate for establishing a strict type.
There's also an issues of self-reporting being less reliable than other factors (people might say they're logical, but are actually quite ethical even if they don't realise it).
I think they are helpful to narrow-down on quadra or club, though.
For example, someone might get results that indicate they're IEE, when in actuality they are an EIE and don't know it. However, from the results you can probably assume they are likely intuitive, ethical, and/or aristocratic, so that gives you a decent chunk of types to think about.
Also, determining introversion/extroversion in Socionics is really hard too, most especially when it comes to self-reported tests, because E/I information elements are not about whether you're shy or outgoing.
And rational/irrational is hard to really judge too, unless you happen to be a very close representation to stereotype.
That all being said, it's good that the results from both give other possibilities of what your type could be in the results.
