No, imbalance would presume things are out of balance.
Your presumtion is that balance = men and women have the exact same interests and should therefore be represented exactly identically in occupations of things & people.
That is an irrational posture, foisted upon you by your media overlords, and accepted by you wholeheartedly without critical analysis.
I do not believe men and women are equal-- if they were, we wouldn't have two names for two genders in a dimorphic species.
If apples equal oranges, we wouldn't have two names for them.
I don't know what sort of mentality you live within, but it isn't a rational nor informed one, in my estimation.
Given the psychological science (again, many studies over the course of decades), and given the biological science (hormonal and brain differences between sexes), I think it is very clear: Women prefer working with people, men prefer working with things -- On average.
I don't think you understand how statistical distributions work. There are two distributions here: One for men, one for women.
They don't both fit onto the same normal distribution-- if they did, it would be bimodal, not normal.
Good lord, I see you're trying to argue against biological differences between men and women-- You must not be aware of hormone differences, which in fetal development, yield either a male or female.
OK, I am done talking with such a brainwashed person. Your ignorance does not offend me, I just think it's pointless to discuss this with an irrational person who prefers to block out the daylight of reality falling upon their presuppositions, and media-informed (not science-informed) perspective.
