It's just the way the male brain is wired.
I think culture influences how that brain is wired, though. The way you're raised, societal expectations; these have a big effect on behaviour—I don't believe that the entire phenomenon is tabula rasa at all, I think there are a lot of external causes that influence as well, too. The "nurture" component is a big big factor.
Understanding this can help us understand our
own emotions and courses of lives better. Our minds and behaviours are more than what we were born with: it's also
how we were born and raised.
Luckily, if we understand what specifically we have been taught and told and how and why, we gain opportunities to reconstruct the narrative in our heads, and get a chance to rewrite the social programming that we run constantly. That social programming influences us
so much that it even writes into our
own internal cognitive programming too, and it changes how we interact with ourselves. How it is inside our
heads. Our ears are open all our lives: What others tell us rings around inside our ear canal and eventually echoes inside our brain. And then we hear those echoes and our internal cognitive dialogue picks up on it, and soon it is a cognitive voice speaking in our heads; this is how we go from someone telling
us something (or merely even
implying) it, to us ending up believing a certain thing—and making it part of what we tell ourselves daily, and what we consider to know and regard as true. I do this too. Understanding how this happens helps us to be a bit less held back by what society imposes on us with certain beliefs: many of which are actively harmful to us, ourselves, and those we value and care about, and ultimately poisonous to the lives we want most, and the
things we want most; such as peace of mind and security.
Hope this helps. We listen to what we tell ourselves. Knowing this; we can understand more
why we think what we think; and hopefully feel less enslaved to what our minds tell us.
As the
old cliché goes:
The mind is an excellent servant but a terrible master.
