A new Channel 4 documentary has taken a fresh look at Adolf Hitler, sequencing his genome and providing insights into his ancestry, biology, and mental health. The two-part series, Hitler's DNA: Blueprint of a Dictator, delves into the science behind the dictator's life and death, but also raises important questions about the ethics of such research.
The documentary's makers have successfully obtained a blood sample from a swatch of fabric cut by a US soldier from the sofa on which Hitler killed himself. This sample was matched to a DNA sample from a distant relative of Hitler's through a combination of luck and historical research. The findings suggest that Hitler had a rare genetic disorder, Kallmann syndrome, which can lead to undescended testicles, or cryptorchidism.
However, the programme also claims that Hitler had a "propensity" for psychiatric conditions such as ADHD and autism. While the documentary acknowledges these risks, it still presents speculative findings without fully addressing them. This is concerning, particularly in the case of autism, where attaching labels to historical figures can lead to stigma.
The use of polygenic risk scores, which estimate an individual's likelihood of developing certain traits or conditions based on their DNA, is also a contentious issue. These tests are often criticized for being inaccurate and overstating the role of genetics in shaping behavior.
Critics argue that the programme blurs the line between biology and behavior, potentially leading to genetic determinism. "Going from biology to behaviour is a big jump," says British psychologist Simon Baron-Cohen in the documentary. This warning seems lost on the programme's editors, who seem to have prioritized sensational storytelling over caution.
Turi King, the scientist behind Hitler's DNA analysis, has expressed surprise at the final cut of the documentary, stating that she was not consulted about the claims made for certain conditions and that they were only "moderately elevated." The decision to air the programme despite these concerns is still puzzling.
Ultimately, the debate surrounding Hitler's DNA reveals deeper issues with how we approach history, science, and ethics. By delving into the genetics of a notorious figure like Hitler, we risk losing sight of the complex human experiences that shaped his life and actions. As one expert notes, "The most troubling thing about this programme is that those involved in making it may have read these passages carefully then continued to make the programme in the way they did anyway."
