THE RETENTION OF ANCESTRAL IDEAS AND BEHAVIOR
The concept of “Ancestral Memory” is pseudoscience. However, metaphysics is ineradicable from a language, the group strategy only adapts but is not replaced, values, traditions, habits persist, and myths survive especially as religions of the hearth and home, and ethnic groups do have certain cognitive biases that survive.
In that sense, yes, we repeat some subset of the memories of our ancestors, but there is nothing genetic, biological, magical, or supernatural about it.
So it is almost impossible to eradicate ancestral behavior from a population without genocide (which is why the jews in particular and muslims at scale commit genocide by reproductive hybridization, civilizationcide, religiocide, historicide, and languicide to defeat their universally superior peoples.
