> Heredity can be measured via twin studies - if twins are adopted into two different families or cultures: what commonalities can we still find, beyond random variability.

And how often does this happen? It is about as common as a sighting of the Higgs boson - and you need a large sample group. Of "identical" twins separated at birth (identical twins are not genetically identical) and sent to two culturally/class-based different families, with little contact.

The Pioneer Fund (you can read about them https://en.wikipedia.org/wiki/Pioneer_Fund ) funded studies like the Minnesota Twin Family Study, but it was found to have many deficiencies, such as what I noted. Often twins in the cohort were only raised apart for a few years and so forth.

On occasion I watch television, and see wealthy heirs like the Hilton heiresses or Kardashian heiresses, or watch documentaries like Born Rich with various heirs and heiresses, and it's quite obvious why such a class spends its money on endeavors that says nature rules over nurture. Like the heir Wickliffe Draper did with the Pioneer Fund. That they are born superior without having to work or do anything. For the past ten millennia they said the gods favored them, like Socrates noble lie ( https://en.wikipedia.org/wiki/Noble_lie#Plato's_Republic ). The popes crowned them king. In our post-enlightened age this does not work so now they say their superiority comes from chains of amino acids. Of course, history tends to depose of them any how, the God-ordained superior genetics of the Romanovs were not as well adapted as the Bolshevik soldiers who rid the earth of them (tangential note - their inbreeding caused hemophilia which brought in Rasputin and hastened their downfall). It's an argument for laziness and parasitism - to not look at people by their work, but by the genetic superiority which they were supposedly born with. It's pathetic and parasitic.
