There’s nobody here yet. I may as well chat with myself a little.
The two men are:
the wise, competent, long lived, nurturing, money-making fatherly type
and
the not so wise, often unreliable and short lived, not so caring, wild child “bad boy” type
The second, of course, often describes a young man, as well. Boys will be boys, and the more wreckless ones seldom have the chance to become men. Not that they all kill themselves off with wreckless behaviour - some merely grow physically, and not mentally.
For an easy pop culture example, think “Job” in the series “Arrested Development”, although he’s a little more of a loser scumbag than a full fledged Fonz or Colin Farrell badboy. Not good enough to be a full fledged “ahole”. Probably the kid who dreamed of being a jock, but was never “good enough”.
Now back to science (or something more scientific, anyway)…
According to David Buss’ research, women historically settle down with the nurturer, and should she cheat… cheat with the “bad boy” when she’s most receptive, when she’s ovulating… and then have the nurturer raise the child as his own.
If you can really map this out in your head, it becomes apparent.
THAT’S why -none mostly gets women hot and bothered when they’re ovulating, then generally repulses them when they’re not (so they won’t break it off with the nurterer).
THAT’s why younger men have higher -none output, and older men generally have higher -rone output (so the 30 something child rearing women will cheat with the new generation of late teen/early 20s men - spreads the genes further)
If you can remove your emotions from the scenario for a moment, you can see that this isn’t all bad. It does keep a “wild card” in the genetic mix.
And it’s not to say that some of the offspring won’t be the nurturers.
Now as soon as you put your emotions back in, you’ll instantly feel the downside.
If you’re the “good guy” you get to raise, unbenknowst to you, some bastard child born of the seed of some guy who had a brief, torrid affair full of hot, torrid, rollicking, insanely delicious bad boy sex with your wife!
You feel the downside because … subjectively, it sucks!
