The ACE pyramid is a self-reinforcing intergenerational circuit, not a linear diagram.

Evidence

Felitti draws a second arrow. This one does not go upward through the pyramid. It points from the apex — from the outcomes — back down to the base. Not the base of the same pyramid. The base of a new one. The pyramid built by his patients’ children. … The circuit is closed. Adverse childhood experiences produce disrupted adults who produce households that generate adverse childhood experiences in the next generation. The pyramid is not a linear diagram. It is a circuit. And the 1998 paper — the paper Felitti is about to finish — will not say so. It will establish the dose-response relationship for the surveyed generation with epidemiological precision that has never been achieved before. What it will not do is trace the loop. — , The Rod and the Child, 7020

  • SEED: Could anchor an essay on why the most famous diagram in public-health trauma research was left incomplete — original authors saw the loop but declined to trace it.
