From a scientific perspective, the thinker is less likely to reproduce.

It could be that the thinker has a much more sound idea of what reality is. It could be the thinkers intellect far surpasses the alpha males, but none of this matters if the thinker cannot function or procreate.

Uhm, the truth is I am not really so sure that that may be true. I have the hunch that thinkers don't need to develop abilities for fitness payoffs because nowadays through Mainstream or Social Media they procreate and they reproduce themselves by binary fission like bacteria most of the time. LoL

When I cared less, I benefited more, and not just financially. I genuinely lived a happier and more social life.

And that's The End Of The Story!! };)

This whole concept makes me think of the saying:
"Curiosity Killed The Cat."

Never forget cats have nine lives. :)
