Is racial trauma “real” trauma, or are we asking the wrong question?
Black women in the U.S. experience nearly double the rate of preterm birth compared to white women, and emerging research suggests this disparity may not be genetic but driven by chronic exposure to racial discrimination, activating the same inflammatory pathways seen in traditional trauma.
In this episode of The Science Chick Report, Dr. Kathleen Kendall Tackett takes on one of the most debated issues in the trauma field. Drawing from her role as editor of the APA journal Psychological Trauma, she challenges the limits of the DSM 5’s Criterion A and explores what happens when the definition of trauma does not match what the body is actually experiencing.
Blending neuroscience with real world data, she explains how the brain does not just respond to physical threats. It also reacts to social rejection, exclusion, and discrimination. At the center of this response is the anterior cingulate cortex, a region that processes both physical and social pain. When activated repeatedly, it can trigger the same stress cascades seen in classic PTSD.
The consequences are far from abstract. Elevated inflammation markers like C reactive protein, higher rates of substance use, increased risk of chronic disease, and even preterm birth begin to tell a consistent story. The body is responding as if it is under threat because in many ways, it is.
This episode does not dismiss the need for clinical precision, but it does push the conversation forward. Trauma, as Dr. Kendall Tackett argues, is not purely objective. It is shaped by perception, lived experience, and how the brain interprets danger.
If we are willing to follow biology, we may need to rethink not just the definition of trauma, but how we recognize, study, and respond to it. Tune in and decide for yourself whether racial trauma fits the definition, or whether it is time to redefine what trauma really means.
