not really. it may be evolutionarily advantageous, and therefore rational, to go berserk if for instance someone touches, or perhaps even looks longingly, at your woman. this crazy, yet sensible, act sends an unambiguous signal to the other primates that if you try to touch my woman, I will get wild and crazy and try to eat your spleen. Also, the woman understands that if she attempts to procreate with another, you may lose it and kill her and all her kin.

I’m not saying this works nowadays, but, you know, it was probably golden during our cave roots days. Those kind of dudes probably got cuckolded less and got more offspring out there. the very same guys whose distant issue are now in domestic violence classes and whose women are hunkering down in shelters.

i’d say it’s more rational evolutionarily nowadays to get crazy over money than mates, since the money is in scarcer supply than sexually available females.

i’d say also in some bsuiness dealings it can be advantageous for the other side to know youa re not entirely rational and may in fact be nuts.
