I took it myself using the book, but it seems to be this one, although there are many clones. But it seems to be the original.

This test, although accurate, is quite tedious, as it requires answering 70 questions. I would recommend this one:

However, it's best to answer consistently, choosing which of the two columns in the same color resonates more with you.

Небо – угроз не слышит
Небо – ведёт особый счёт
Небо – тебя найдёт

Here, it would be better not to place the options randomly, but to choose which of the two columns, with the same color, you find more appealing.
I, for example, am neither.

On the left, in the "sociability" column, opposite is "concentration." Again, fails! Why must a sociable person necessarily be absent-minded, and a concentrated person be unsociable?
I, for example, am neither.

I'll continue playing, and I'm sure I'll encounter questions that don't have the answers I need in the list.

Your sociotype: sensoric-ethical introvert - "Duma"
Sociotype of your dual: intuitive-logical extrovert - "Don Quixote"

Lizard correctly pointed out the middle ground.
Also, silence does not equal concentration.
I am absent-minded and inattentive.
But I know many people who are more focused, concentrated, and quite sociable.

1. S - sensory perceptionA person who enjoys familiar pleasures and simple everyday joys. They are very considerate of the habits and comfort of those around them.
The key to "wit" implies communicating based on the situation. For example, you're walking down the street with a girl and you see a bus with a sushi advertisement. You can ask if she likes sushi, and then, perhaps, the conversation will turn to Japan, from Japan to earthquakes, and so on. In other words, the conversation is structured like a tree grows – a trunk grows, branches grow from it, more branches grow from those branches, and so on, branching out to form a crown. Thus, your conversational path goes from the trunk to the thinnest twig, and the entire crown with thousands of twigs represents your conversational possibilities.
And, of course, in addition to using a logical chain, the emotional and personal aspect is important, as is non-verbal communication. In any mutual conversation, you always have to touch upon the personality of the conversational partner and their reaction. And based on their reaction, you should adjust your own.
Well, I wrote it a bit complicated. In reality, you just need to show wit and be cheerful. :)
