I attribute instability of slavic women to their slavic soul.
I searched for the data that could indicate that there is some instability. I tried with the incidence of big psychiatric illnesses, specifically bipolar disorder and major depression. General stats show that prevalence of big ones is similar everywhere. Depression seems to be more the illness of the West (but there we have problem differentiating reactive from endogenous depression, their codes are the same, I think that that difference is caused by environmental factors and diagnostic practice).
Bipolar is slightly more often seen in Slavic world, which suggests that moodiness might have innate nature.
This is a very shaky and problematic hypothesis and has idiosyncratic purpose, I had to explain that to myself somehow.
But I also think it's just a problem of having that stupid soul I would gladly sell /give away if there would be some devil to buy it :))
General passivity as a feature is what you describe as lack of expressed will?Or the negation imperative?Nechatsiu.Nechci.
I think that problem with the will is both nurture and nature problem.
From what I have seen I can conclude that many the members of Slavic nations don't impose strict rules or harsh discipline on their kids like their counterparts.
Our kids behave like the rulers of the world.
I was watching the reaction of one Danish couple on the beach while they were observing ordinary Serbian kid routinely ruining his toy (some water gun).
The kid was yelling, singing while splashing the water surface with the toy until it fall completely apart. The couple was annoyed until that moment, noise he was producing was quite unpleasant. But when the mother of the kid started to comfort the boy who was screaming because the toy is finally broken, trying to calm him down employing half of the beach to search for the parts of the toy in the water he just destroyed , the faces of that Danish couple changed to shock.
In Germanic ! countries I didn't hear many sounds produced by kids.
I think that it could be the case with all Slavs, but for Serbs I heard that they have this reversed type of authoritarianism. While authoritarian Westerner obeys the rules even when they are ridiculous (or harmful) and nobody can see him braking it, Serbian authoritarian type of personality will brake the rule just to brake it.
What I meant to depict with those examples is that will as a word appears mostly in sentences that show lack of it.
I will end this novel disagreeing with everything written above.
