Why guys are bastards/jerks

Why is it so common to hear of a guy being a jerk/bastard/asshole/insert own derogatory term, and to hear of girls being...complicated?
It's not rocket science, rather it's simple and straightforward.

It is...genuinely wired in our brains, due to our primitive needs.

Personally, I adopt a Freudian approach to social needs because I truly believe Freud was spot-on when he said humans were motivated by needs, and the need for continuity of the generation gave way to the need for sex.

That was apparent during the primitive stages and still remains active today. How many billboards do you have to see to believe that sex DOES sell? Because it does. It's the one natural activity that we learn to enjoy (well, discounting eating, that is) and at the same time, it ensures that our species continues for at least a few more generations.

So I deviate. Back to why guys are bastards...
Due to our primitive needs, its only natural that guys are wired to want to spread their seed as much as possible while girls are wired to take care and protect the household. (Hold off the feminist insults for at least a few posts, that's a topic for another day.)

But of course, you don't see humans walking around like savages or with leopard skin leotards anymore (unless your a wrestler), so society has placed cages, proper habits and what-nots to bring us up prim and proper. Yes, we treat each other with respect and practise common courtesy but our natural wirings cannot be manipulated entirely by the way society works.

So our brain evolved, in a way to cope with the societal pressures of treating the opposite sex, that coupled with feminist movements in the 20th century, and for the least part, developed countries have more-or-less decided on a set of proper habits.

And all these, I'm afraid...have contributed to guys=bastards.



The graphs are pretty self-explanatory. (Some of you have prolly seen it)
Allow me to bring your attention to three main points.

At coordinate 0, it is apparent that males have high interest levels to start off with, while female have low interest levels.

That is why guys can like girls for whatever reason...we don't even need a reason to like someone..(Just like how girls don't need a reason to shop)

That is also why girls find it hard to like guys without first getting to know them, and are hence defensive at the start.

At point a, assuming that the relationship has followed a general path, the male's interest begins to dovetail while the female is slowly but surely beginning to love her opposite number.

It's easy and normal to hear guys saying they're getting bored being with their girlfriends and wondering what it'd be like being single.

Nearing the end, it's plain to see why so many relationships fail or ultimately end up in a dry and one-sided affair.

It's not the guy's fault. It's both of them.
I've had friends who remarked "I just don't know why I don't love her anymore...my feelings just faded like that..."
And that...is the real tragedy.

By acknowledging this behavioural trait in both sexes, a couple can learn to navigate the twists and turns of a relationship together.
