The emergent concept of the epigenetic inheritance of trauma across multiple generations has gained widespread attention in popular media, arguably at the cost of sufficient critical evaluation. This oversight risks distorting the complex and multifaceted nature of trauma transmission, with potential consequences for affected individuals and the broader society. Specifically, the prevalence of this oversimplified narrative in social work and healthcare settings underscores the need for a clearer and critical understanding of the science. To address this need, this work aims to support social workers and other healthcare workers that are interested in better understanding the biological basis of epigenetics as they integrate emerging research on trauma transmission into their daily practice. The paper first introduces fundamental concepts in epigenetics for a non-expert audience, clarifying key mechanisms that regulate gene activity. Building on this foundation, the authors examine sociocultural and biological models for trauma transmission, based on the current evidence, drawing on historic examples to highlight the strengths and limitations of each model. Ultimately, the authors encourage social workers to bridge both of these perspectives in trauma-informed care to enable social workers to challenge misconceptions about inherited trauma and foster patient empowerment through accurate education and advocacy, promoting more holistic and effective care.
