The 1939 Monster Study: A History of Unethical Research

The 1939 Monster Study remains a chilling example of unethical research, a dark stain on the history of psychology. Conducted by Wendell Johnson at the University of Iowa, this study inflicted lasting psychological harm on its young participants, highlighting the critical need for ethical guidelines in research. Understanding its methods and consequences is crucial for appreciating the evolution of ethical standards in scientific experimentation.

The Horrifying Experiment: A Deliberate Infliction of Harm

The Monster Study, officially titled "An Experimental Study of the Effects of Induced Stuttering," involved 22 orphan children as subjects. These children, already vulnerable due to their circumstances, were divided into two groups:

• Group 1 (The Experimental Group): These children received positive speech therapy, praising their fluency and reinforcing positive speech habits.
• Group 2 (The Control Group): This group, unfortunately, underwent a brutal process of negative speech therapy. They were subjected to harsh criticism, ridicule, and negative reinforcement for every speech imperfection, designed to instill feelings of inadequacy and self-doubt about their speech.

The aim was to determine whether stuttering could be induced through negative reinforcement. The horrifying reality is that the researchers succeeded, inflicting lasting psychological damage on several children in the control group. Some developed speech problems that persisted throughout their lives, a testament to the study's devastating impact.

The Lasting Scars: Psychological Trauma and Ethical Violations

The long-term consequences for the children involved in the Monster Study were severe. Many suffered from significant psychological trauma, including anxiety, depression, and lasting speech impediments. The study fundamentally violated the basic ethical principles of research, notably:

• Informed Consent: The children were orphans, unable to provide informed consent. Their guardians were not adequately informed about the nature and potential risks of the study.
• Minimizing Harm: The study deliberately inflicted psychological harm on its participants. The researchers prioritized the pursuit of knowledge over the well-being of vulnerable individuals.
• Beneficence: The study did not offer any potential benefit to the participants. The only outcome was the infliction of psychological distress.
• Justice: The selection of orphaned children as participants raises serious questions of justice and equity in research. These children were a particularly vulnerable population, exploited for the sake of scientific advancement.

The Aftermath: Lessons Learned and Ethical Reform

The Monster Study’s legacy extends far beyond the suffering of its participants. It serves as a stark reminder of the potential for scientific inquiry to be misused and the importance of rigorous ethical review processes. The study led to significant changes in research ethics, prompting the development and stricter enforcement of ethical guidelines for human subjects research. Institutional Review Boards (IRBs) were established to review research proposals to ensure they adhered to ethical standards, protecting vulnerable populations from exploitation.

The Importance of Ethical Research Today

The Monster Study is a cautionary tale, reminding us of the necessity of ethical considerations in all research involving human participants. Today, ethical research demands rigorous adherence to principles like informed consent, minimizing harm, beneficence, and justice. The legacy of the Monster Study compels researchers to prioritize the well-being of participants, ensuring that the pursuit of knowledge never comes at the expense of human dignity and ethical conduct.
