Mary Shelley’s 1818 novel Frankenstein served as a chilling prophecy of the ethical dilemmas that science could pose. From the Tuskegee Syphilis Study to the CIA’s MKUltra program and the recent controversy surrounding the world’s first CRISPR-edited babies, the line between science and fiction has been blurred, often with dire consequences.
The Tuskegee Syphilis Study: Withholding Treatment for Decades
In the early 20th century, the U.S. Public Health Service and Tuskegee Institute embarked on a study that would become one of the most infamous examples of unethical medical research. The Tuskegee Syphilis Study, conducted from 1932 to 1972, involved withholding penicillin from 399 African American men diagnosed with syphilis, even after the drug’s effectiveness was proven in 1947. The researchers, led by Dr. Taliaferro Clark, deceived the participants by presenting the study as a “bad blood” treatment program, providing placebos instead of actual therapy. The experiment was only terminated in 1972 following exposure by whistleblower Peter Buxtun.
MKUltra: CIA’s Mind Control Experiments
Another chilling example of science crossing ethical boundaries is the CIA’s MKUltra program. Conducted from 1953 to 1973, this program involved secret experiments on human behavior modification using LSD, hypnosis, and electroshock. The subjects, who were often unaware of their participation, included mental patients and prisoners across at least 80 institutions in the U.S. and Canada. The program involved dosing individuals without their consent, leading to long-term psychological damage and even death in some cases.
The Monster Study: Inducing Stuttering in Children
At the University of Iowa in 1939, speech pathologist Wendell Johnson and graduate student Mary Tudor conducted an experiment known as the “Monster Study”. This study involved 22 orphans who were divided into groups and subjected to either praise or criticism for their speech in an attempt to induce stuttering. The negative feedback given to some of the children led to self-consciousness and speech impediments, causing lasting trauma. The existence of the experiment remained hidden until 2001 when it was uncovered by a University of Iowa historian.
Nazi Medical Experiments: Atrocities in Concentration Camps
During World War II, Nazi doctors conducted a series of horrific medical experiments in concentration camps. These included twin studies by Dr. Josef Mengele at Auschwitz-Birkenau, where he injected chemicals into the eyes of twins to change their color and conducted surgical experiments without anesthesia. At Dachau concentration camp, Dr. Sigmund Rascher conducted high-altitude and hypothermia experiments on prisoners, resulting in numerous deaths. These atrocities led to the establishment of the Nuremberg Code, which set ethical standards for human experimentation.
He Jiankui’s CRISPR Babies: Gene Editing in Embryos
In 2018, Chinese scientist He Jiankui announced the birth of the world’s first CRISPR-edited babies. The twin girls, Lulu and Nana, were born with altered genes for HIV resistance. He recruited eight couples for the experiment, where the fathers had HIV and the mothers did not. The experiment led to a global outcry and He’s dismissal from his university, highlighting the ethical concerns surrounding gene editing in humans.
Sergio Canavero’s Head Transplant Vision
Italian neurosurgeon Sergio Canavero made headlines in 2013 when he proposed the HEAVEN/ GEMINI project for human head transplantation. Canavero planned to sever and reconnect the spinal cord using polyethylene glycol, a procedure inspired by earlier animal experiments. Despite announcing a volunteer for the procedure, it never occurred due to ethical condemnations and lack of approval. This case serves as a reminder of the ethical boundaries that must be respected in scientific research.
