Anybody who has a whole buncha kids knows that the same set of genes from the same two parents can produce kids with wildly different personalities.
Any parents with "identical" twins knows they can have different personalities.
There are a few herds of genetically identical cloned cows, the cows in these herds exhibit the same ranges of temperament that would be found in a herd of cows made the old fashioned way.
I have 5 children
All different but similar physically and personality wise
And I can see physical and personality traits in them from their forebears distinctly as can their mom
Myself...I am basically my grandfather looks and personality
At my age I even notice mannerisms and walking styles and gestures in my kids which I saw in older relatives I knew
Nobody will convince me mental aspects are not inheritable
A warning for anyone...not you
Behavioralism.....think Skinner....is the cornerstone of humanism
I’m convinced just from observance that we are more nature than nurture baring extreme environmental variants
Of course.... let’s say the developed world agreed....then what to do about it
The bitter contradiction is that through soft bigotry and liberal paternalism
Our culture does but denies it.
