The Definition of Insanity

Often, I hear some variation of a quote attributed to the late German-born theoretical physicist Albert Einstein that proposes, “The definition of insanity is doing the same thing over and over again and expecting a different result.”
Noteworthy, Einstein wasn’t a practitioner of mental, emotional, or behavioral health. He wasn’t a psychiatrist, psychologist, counselor, social worker, psychotherapist, or psychological therapist of any kind, to include functioning as either a theorist or academic in this field.
Furthermore, one source reports, “There is no substantive evidence that Einstein wrote or spoke the statement above,” as the resource proposes that the quote was actually found in a pamphlet printed by the Narcotics Anonymous organization in November 1981.
Moreover, physicists are practitioners of science. As such, it’s likely the case that Einstein was familiar with the scientific method. Regarding this procedural approach to interpreting truth about reality, one source states:
It involves careful observation, applying rigorous skepticism about what is observed, given that cognitive assumptions can distort how one interprets the observation. It involves formulating hypotheses, via induction, based on such observations; the testability of hypotheses, experimental and the measurement-based statistical testing of deductions drawn from the hypotheses; and refinement (or elimination) of the hypotheses based on the experimental findings.
Scientific experiments are intended to be reproduced. Otherwise, one may end up with a replication crisis—an ongoing methodological crisis in which the results of many scientific studies are difficult or impossible to reproduce.
As such, doing the same thing over and over again and expecting a different result is a component of the scientific process. Therefore, such behavioral and cognitive actions aren’t insane. Alternatively, in a blogpost entitled Insane in the Membrane, I stated:
[T]hat which is colloquially considered to be insane doesn’t indicate insanity which the American Psychological Association (APA) defines as “in law, a condition of the mind that renders a person incapable of being responsible for their criminal acts.”
Also, different regions within the United States (U.S.) maintain contrasting legal definitions and statutes regarding legal insanity. Interestingly, there’s no APA definition for “insane” or “crazy,” though the term “mental disorder” is thusly defined by the Association as:
[A]ny condition characterized by cognitive and emotional disturbances, abnormal behaviors, impaired functioning, or any combination of these. Such disorders cannot be accounted for solely by environmental circumstances and may involve physiological, genetic, chemical, social, and other factors.
The important takeaway point thus far is that “insanity” is a legal term, “mental disorder” is a medical term, and “insane” is merely a term commonly used to indicate irrationality—that which isn’t in accordance with both logic and reason.” This distinction is relevant.
Understanding the framework outlined herein, it’s not an insane act to brush one’s teeth daily while expecting whiter teeth than the previous day. That’s because the definition of insanity isn’t doing the same thing over and over again and expecting a different result.
