A paradigm shift brings a fresh way of looking at the world. Give an example from the field of medicine that shows how normal science has experienced a paradigm shift in the last 200 years. For example, at one time, physicians did not believe that germs lived on human hands. They operated with bare, unwashed hands. The entire framework for studying and preventing infections changed with the new knowledge about microorganisms.

One example of a paradigm shift in the field of medicine over the last 200 years can be seen in the understanding and treatment of mental illness. Prior to the 19th century, mental illnesses were often attributed to supernatural causes or moral failings and were treated through practices such as exorcisms or physical restraints.
However, with the advent of scientific inquiry and advancements in understanding human physiology and psychology, a paradigm shift occurred in the understanding and treatment of mental illness. This shift was spearheaded by the work of figures like Sigmund Freud, Carl Jung, and others.
Freud's psychoanalytic theory, introduced in the late 19th and early 20th centuries, revolutionized the way mental illnesses were conceptualized and treated. He proposed that unconscious conflicts and unresolved childhood experiences could lead to psychological disorders. This shifted the focus from supernatural causes to exploring the internal dynamics and unconscious processes of the mind.
Further advancements in the understanding of mental illness included the development of biological psychiatry, which emphasized the role of neurobiology and genetics on mental health. The discovery of psychotropic medications, such as antidepressants and antipsychotics, also had a significant impact on the treatment of mental illness.
These paradigm shifts in the understanding and treatment of mental illness transformed the field of medicine by replacing traditional beliefs and practices with evidence-based approaches. It brought about a movement towards a more comprehensive, scientific, and compassionate understanding of mental health conditions. This shift has had far-reaching implications for the diagnosis, treatment, and stigma associated with mental illness.
