Discovery in Mexican Cave May Drastically Change the Known Timeline of Humans' Arrival ...

24. right handed dominance is 'credited' to tool-making or language but sowb goes back to our earliest

ancestors, long before those factors.

reproduction is right up there with hunger and thirst. you saying it wouldn't effect our evolution?

and the divided brain goes back farther than that, including to birds, for instance. the idea the it wouldn't matter what hand we masturbated with wouldn't make a difference is ridiculous. back then life was shorter and reproduction started earlier.

our societies have formed around the increased irrational need for certainty - caused by associating impatient satisfaction-demanding reproductive impulses with brain functions that need patience and objectivity. logic is satisfied with finality, conclusion - certainty. authoritarianism is sometimes measured with the uncertainty avoidance index (UAI). authoritarians use order, simplification, absolutism to simplify the world/nature and help them judge the world in black and white, good and evil, etc. we invented religion to ease our fear of uncertainty and help us manufacture certainty.

the right brain is generally more engaged in emotion, sex, orgasm - why associate sex with the side of the brain that has more to do with detail, math, logic?

it was a slight advantage over millions of years that got much worse in the last few thousand years as humans necessarily began to delay the age of reproduction. at some point authoritarian leadership may have recognized the best way to create an army was with sexual repression - to keep young men frustrated and jacking off - by default with the wrong hand. the koran left the secret of authoritarian power in, mandating that "man can only have sex with his wife and that which the right hand possesses..."

populations in different environments selected for particular sowb symptoms which eventually manifested as inherited susceptibilities for particular sowb symptoms. so descendants from european "old world" civilizations may be more susceptible than those from the 'new world', and it looks like trump got bad genes for a modern democracy, but perhaps not for a monarchy.

is the disparity in sow a source of bigotry, racism, sexism?

authoritarian societies have a built in defense - as joycelyn elders found out, even mentioning the word 'masturbation' is out of bounds.
