Here are the women reproducing: Pretty much most women will reproduce, but the most trashy fat stupid women will reproduce the most.

Here are the men that will reproduce: tall men, lower IQ men and narcissistic/sociopathic men who do not care about social norms or the men who are so weak and lack self-respect that they finally get a woman at 38 with one kid.

So with modern dating, we've essentially made it so that humanity is merely defined by just being the most attractive to the opposite sex in the immediate, not any actual merit. We will create bigger, dumber, trashier people as time goes on, because those are the types that get sex the most.

The outcome will either be some form of Idiocracy, but worse with the trashiest, dumbest sociopathic people reproducing. With the pattern, the only places safe from the new trashy humans are highly rural places like Africa and upper class communities.

I've often times wondered if humanity is worse as it is now than in the past because we're all cowards. Maybe it's always been like this.
