Studies on adopted children raised by parents in hostile marriages: show (obviously) that frustration and anger begets frustration and anger … irrespective of genes.
“Although there was no direct association between birth mother anger/frustration and toddler anger/frustration, as noted above, birth mother anger/frustration significantly moderated the relation between adoptive parent marital hostility and later toddler anger/frustration. This genetic moderation is consistent with the premise that children whose birth mothers report higher levels of anger/frustration inherit an emotional lability, making them more susceptible to the negative impact of marital hostility.”
But, for an unfortunate few … the doubly unfortunate experience of having an “inherited emotional lability” while being raised in an emotionally harsh environment, can mean a lifetime of emotional anguish, stress-related-physical suffering and falling through the cracks of society.
