i was mulling over the elemental socionics constructs, specifically the dichotomies. as I gathered from this thread dichotomies were incorporated into socionics directly from jung, who based them on personal observations and speculation. so are socionics dichotomies completely arbitrary, imaginary constructs? or does the fact that jung has based them on some kind of observations mean that there is something of objective reality that necessitates their existence? what are your opinions on this?
