According to socioniko.narod.ru/en/articles/talanov-visual.html
rational types are described in the following way:

When he sits down, he keeps his back straight, rarely bends aside, even when he leans upon the chair back

Irrational types are described in the following way:

their whole appearance seems “fluid”, loose, their body is easily bending, takes the shape of the arm-chair, sofa etc…; when they sit down – they lean upon the chair elbow-rests or back, and their own back may bend a lot

I am an INTj (rational) but the irrational description describes me much better.

Do other INTj's on this forum have the same issue to me?
