I was reading something that suggested that trauma "tries" to spread itself. ie that the reason why intergenerational trauma is a thing is that the traumatized part in a parent will take action to recreate that trauma in the child.
This model puts the emphasis on the the parent's side: the trauma is actively "trying" to spread.
This is in contrast to my previous (hypothetical) model for IGT, which puts the emphasis on the child's side: kids are sponges that are absorbing huge amounts of info, including via very subtle channels. So they learn the unconscious reactions of the people around them.
(I say "hypothetical", because all while this sort of thing is in my hypothesis space, I haven't seen clear enough evidence that intergenerational trauma is a meaningful category that I solidly believe it is real.
More like, "here's a story for how this could work.")
On first glance, I was skeptical of this "active trauma" story.
Why on earth would trauma be agenty, in that way? It sounds like too much to swallow.
