How To Stop Burning Witches...

 


I was hoping for a timely post for Halloween but just missed the deadline. Witches are considered an icon of the season, although I have not seen a lot of those costumes recently. I came across an important book that analyzed the witchmongering movement in 15th to 18th century.   Witchmongering was term was coined by Reginald Scott in 1584 in his book The Discoverie of WitchcraftHe used it to describe people promoting the ideas and superstitions about witchcraft – specifically those who profited from spreading these ideas.  His book discusses the idea that witches have connections to the devil and Scott’s position was that this was all imaginary.  He studied magic and concluded that the belief in witchcraft was rooted in illusions, imposters, or inaccurate conclusions due to mental disorders.  He sought to prevent marginalized individuals from being attacked as witches.

Despite Scott’s rational approach, witchmongering was actively debated for at least another century.  Thomas Ady wrote A Candle in the Dark in 1656 and took a similar position.  Popular opinion about the existence of witches and their presence began to wane around 1700, but witchcraft laws and executions persisted much longer. In Great Britain the Witchcraft Act was repealed in 1736.  By the late 18th century most witchcraft prosecutions and punishments were banned in Europe. The last witchcraft trial in the US was in 1878.  There is a detailed history of both witch hunts and executions of witches resulting in the deaths of tens of thousands of women.  Even though most people do not know the details of this dark practice – the concept witch hunt is used rhetorically these days to indicate an unfair investigation.  

There are various ways to analyze the history of witchmongering. Social scientists have looked at anthropological and sociopolitical analyses. Rhetoric seems like a powerful approach to me because humans seem to use the same patterns over time to make irrational decisions.  Rhetoric is a component of cultural inheritance.  In the case of witches – anxiety provoking events like crop failures, illnesses, economic and political instability, religious and sexist biases could lead to accusations of witchcraft.  But once the precedent was set behaviors, social factors, and personality factors could also be included as well as accusations of supernatural phenomenon like sorcery and causing people to disappear.  There is no doubt that some had mental illnesses but that is not currently considered to be a major factor in the women who were persecuted.

Ady describes a common scenario in his era. The poor and disabled went door to door in those days asking for relief. Many were elderly, malnourished, and disabled. If they were denied assistance by the landowner and his crops or cattle failed or one of his family fell ill – that person could be blamed for witchcraft as a source for these problems.  They could be subjected to false tests or torture and sentenced to death as a witch.  

Once these negative qualities were specified as evidence, the sequence of events proceeded in the same manner that can easily be observed in modern American politics.  If enough people are anxious about some matter, it is easy enough to incite them.  Just claim that you are the only person who can solve that problem and find a group that is the modern equivalent of witches to blame.  In recent months we have seen documented and undocumented immigrants, women, non-white minorities, university professors, public health officials, public sector employees, the disabled, the economically disadvantaged, the food insecure, members of the previous administration, and just about anyone who is a critic of the current administration. Scapegoating a small segment of the LGBTQ community may have been the deciding factor in that last Presidential election and it continues to be an issue.

Ady’s book is a tour de force against witchcraft.  He begins his three part treatise by directly confronting popular notions of witchcraft with the Biblical moral code of the day.  He lists 16 – “where is it written” or “it is written” clauses in his introductory “A Dilemma that Cannot bee answered By Witchmongers.”  In the subsequent text he elaborates on how references to witches have been misinterpreted to fuel witch misinformation.  An excerpt of the Dilemma is reproduced below.  Note that the original spellings are preserved:

 


 

At the end of this this volume he gives two excellent counterfactuals to falsify witch mongering. It is clear from these examples that any misfortune can be erroneously ascribed to witches and therefore witch mongering and everything that involves adds no explanatory power.  That is made much worse by the fact that this non-explanation resulted in the deaths of thousands.    

 


 Moral reasoning and rationalism was used to discredit witch mongering but they were not the sole factors.  Johann Weyer (1515-1588) was a Dutch physician who argued that witches were mentally ill suffering from melancholia.  He thought that any confessions of witchcraft were based on delusional thinking.  He published numerous works on witchcraft and magic. 

Medicine, science, and rational thought were not enough to immediately correct the practice of persecuting women as witches.  Pseudoscience and various “tests” were used to prove that a woman was a witch.  Many of these tests defy reason like the pseudoscience of the current era.  For example, one test of a witch was to bind them, throw them into a body of water and see if they float.  Certain marks on the skin were taken to be the marks of a witch.  That included puncture marks inflicted with needles by others – if the puncture wound did not bleed it was considered evidence of a witch. Ady provided counterarguments about why these were inadequate tests.  Needless to say there were no control groups. 

Despite Weyer’s direct observations there are competing theories that social and cultural factors were important.  It is likely that both played a part, with psychiatric etiologies as suggested by Weyer playing the minor part.  If you are identified as a physician who works with a particular problem – it is likely that selection bias is operating in the clinical population that you see and treat.  Cultural symbols are often incorporated into psychotic symptoms.  In 40 years of practice – I saw a handful of people who believed they were Christ-like and many more who believed they were the Antichrist. During the time of Satanic Ritualistic Abuse (SRA) I saw many people who were not delusional but believed that they had witnessed homicidal rituals by satanists.  Those are all modern examples of observations that were not accurate and could be scientifically disproven.

If we agree that witch accusations and persecutions were psychiatric, social, and cultural in origins are there some common factors that might account for these patterns?  Anti-intellectualism is a complex societal problem that has been examined by Hofstader, Pigliucci, and others (3-5).  Hofstader traced some of it back to right wing politics and religion in the 1950s where it still resides today.  Hofstader described 3 forms (antirationalism, anti-elitism, unreflective instrumentalism) to which Rigney added unreflective hedonism and Pigliucci added academic post modernism as a fifth (4).  Pigliucci also added a qualifier that post modernism may be an intellectual anti-science field.   

The refutation of witchmongering is an important lesson for people in modern times. Reasoning and moral reasoning based on Christian principles and local laws eventually carried the day – but it took a long time. Science through early observations of mental illness were a small part of the story.  The most significant aspects of this historical period is focused on cultural inheritance and rhetoric.  Neither of those dimensions is necessarily predicated on the truth.  The commonest ignored pattern is the use of a scapegoat to avoid the reality of the situation or in the worst case divert attention to an emotional topic that is really all part of the scapegoating.

We typically see these issues categorized as hot button issues or culture wars.  They are responsible for large scale irrational decision making about guns, abortion, welfare, religion in schools, banned books, restricted access to voting, racism, misogyny, the medically uninsured, and corporate welfare.  They are currently responsible for the dismantling of basic research, health care, food subsidies, public health, foreign aid, the Department of Justice, the Department of Defense, and the layoffs and firings of 200,000 federal employees.  There is an estimated large death and morbidity toll associated with those decisions.

While we are no longer naming witches and prosecuting them – a lot of the thinking behind that process has been passed along as cultural inheritance and the associated rhetoric.  A significant number of Americans react to it in expected ways.  Recognizing the pattern of scapegoating and the associated emotions is a critical first step.  The second is to figure out what science is and what it is not.  Science is definitely not doing your own research unless you have been trained in the scientific method or (ideally) are a scientist.  The ultimate ability is to be able to use reason, moral reason, and science to make the best possible decisions.

That is the best way to avoid more witchmongering.

Psychiatry - Science and Pseudoscience

I finished the first chapter in Philosophy of Pseudoscience: Reconsidering the Demarcation Problem by Pigliucci and Boudry.  I became aware of Massimo Pigliucci and his work back in 2002 when I read his book on Intelligent Design and since then have discovered his blog Rationally Speaking where he has recently posted his best papers from his careers as a scientist and a philosopher.  He writes very clearly on the philosophy of science and has such a command of the field that he can include a history lesson of relevant references.  He also does not shy away from controversy or the apparent lack of a clean solution to a problem.  One of the central concepts in his chapter is this chart of empirical knowledge versus theoretical understanding. (click to enlarge)



The purpose of this essay is to look at possible boundaries between science and pseudoscience as well as a couple of interesting observations as they apply to psychiatry.  One of his key concepts is that the lines of demarcation are not necessarily sharp and the variables are not necessarily linear.  He uses the above graph of empirical knowledge versus theoretical understanding as an example.   Starting in the upper right corner of the diagram we have hard sciences with particle physics given as the most clear cut hard science.  I like to think about my undergraduate chemistry experience as being hard science.  Even introductory chemistry exposes the student to an amazing array of facts, observations, and theories that are incredibly accurate.  From there, chemistry majors build on their ability to measure specific compounds, synthesize them and study the theory in Physical Chemistry.   I don't think that there is any doubt that chemistry as a field is not too far removed from particle physics in terms of empirical knowledge or theoretical understanding.  String physics has much theory but is low in terms of empirical support.  He refers to evolutionary psychology,  scientific history and Search for Extraterrestrial Intelligence (SETI) as a "proto-quasi science" cluster with decreased amounts of theory and empirical support.  Other fields like the so-called "soft sciences" of sociology, economics, and psychology have a fair amount of empirical knowledge but less theoretical understanding.  The true pseudosciences are in the zone with astrology, HIV denialism, and Intelligent Design.  From the history of psychiatry - Freudian psychoanalysis and Adlerian psychology would also be included here but there is also a list of theories from general medicine and surgery that would also qualify.

In psychology and psychiatry a central philosophical problem is the so-called hard problem or the explanatory gap between the neurobiology of conscious states and subjective experience.  This is exactly where psychiatry resides.  A lot of political criticism of psychiatry involves the ability to parse these states and accurately classify different conscious states.  Resolving the hard problem would move psychiatry and psychology firmly to the right in the demarcation diagram but probably not nearly as far as particle physics or maybe not even as far as molecular biology.

The relevant question for me of course is where psychiatry fits on the plane of empirical knowledge x theoretical understanding.  What about medicine in general?  Could we plot a plane of medical and surgical sub specialties on this plane instead of the hard and soft sciences?  Does medicine and surgery have theories or practices end up in the same zone as Freudian psychoanalysis.  Of course they do.  A great example from my days as a medicine intern was highlighted by Ghaemi as "The cult of the Swan-Ganz catheter."  In the places where I trained, anyone with moderately serious cardiopulmonary problems was at risk for placement of a Swan-Ganz catheter.  The actual person inserting the catheter could be a medicine resident, a cardiologist, or an anesthesiologist.  Since the intern is responsible for doing the initial history and physical exam, I witnessed the placement of a large number of these catheters.  Once placed they gave an impressive number of parameters on ICU monitors.  We were routinely grilled about the meaning of these parameters by attending physicians on rounds.  It all seemed very scientific.  The cult of the Swan-Ganz catheter was subsequently disproved by randomized clinical trials.  This standard of care from the 1980s and 1990s disappeared much faster than Freud.

The best way to plot medicine and psychiatry on Pigliucci's empirical knowledge versus theoretical understanding plane would be to consider the clinical basic sciences taught in the first two years of medical school.  In my experience that was anatomy, neuroanatomy, histology, microbiology, biochemistry/molecular biology, genetics, pathology, physiology, pharmacology, epidemiology, and statistics.  Practically all clinical specialties carry these basic sciences forward in one form or another.  The research literature in any particular specialty in full of theory and techniques from these basic sciences.  The psychiatric literature cuts across all of the basic sciences in the same way as other specialties.  At the minimum, some of psychiatry will be at the level of molecular biology on the diagram in some areas and at the level of psychology in others.  Hopefully the unscientific theories will be relegated to the lower left hand corner of the diagram as unscientific and not stand the test of time.

I think that Professor Pigliucci's conceptualization is a very useful one.  I expect that he will continue to refine these ideas.  I think that measurement precision and categorization may be important dimensions to add to these concepts.  As Merskey has pointed out both the phone book and the periodic table are much more accurate forms of categorization than any scheme of medical classification.  I think that probably says a lot about the underlying scientific dimensions and how measurement is done.

Two Undergrad Experiments to Illustrate - What Is Science?

I have always been somewhat of a science nerd and had what I consider to be a first rate science education at a liberal arts college.  I had gone to this school on a football scholarship with the intention of becoming a phy ed teacher and a football coach, but the science education there was too compelling to ignore.  I ended up being a biology and chemistry major and rapidly forgot about football.  Brook's essay of what is science, what is the most compelling science and how that  makes psychiatry as far from science as possible led me to think about memorable experiments from my undergrad days.

Experiment 1:  The Limnology experiment:   For a while in my undergrad career, I considered being a limnologist or fresh water biologist.  My undergrad college was one of the first to emphasize the environment and ecology.  A lot of the work involved doing population estimates of plankton and aquatic invertebrates.  We spent hours classifying and counting thousands of organisms  that are unknown to most people. We used various sampling techniques and statistics to determine populations of these organisms and whether they seemed to be influenced by any environmental variables.  At one point I had equations from an journal article to calculate the probability that a specific species would be in contact with another one - called the "probability of inter species interaction."  This is biological science.

Experiment 2:  The PChem experiment:  Physical Chemistry was the undergrad chemist's dream course when I was in college.  You dreamed that you would be able to pass it.  We had a text that was not very accessible, but a professor who was brilliant, very accessible and an excellent lecturer.  I liked it a lot after we finished thermodynamics and moved on to other topics.  Back in the 1970s we had very primitive computing power. Our lab had an old HP calculator that was as big as a current desktop with less computing power than a modern day scientific calculator.  One of our tasks was to estimate electron densities around carbon atoms in aromatic hydrocarbons.  In an afternoon in the lab we ran the numbers.  This was the science of physical chemistry.

I have intentionally left out all of the details of the experiments because for the purpose of comparison with Brooks thesis they are unnecessary.  From his essay we learn that biology and chemistry are real sciences with a "distinctive model of credibility".  The examples I have given are from those fields.   We learn that psychiatry is a "semi-science" because "the underlying reality they describe is just not as regularized as the underlying reality of say, a solar system".  I will stop at that point because Brooks further examples rapidly degenerate.  What do we have so far?

Looking at my experiments, #2 clearly has the regularity of a solar system.  What could be more regular than the electron density for a specific molecule?  It fits Brooks definition of science to a tee.  What about experiment #1, the biological experiment?  Here we have a number of organisms.  Some have nervous systems and the others (eg. phytoplankton) do not.  I did a series of calculations to look at the probability of one species encountering another.  There were certain assumptions to those calculations about randomness to make the calculation much easier to do.  But what if I wanted for a moment to be a "behavioral limnologist" and attempt to predict the behavior of a specific stoneflies in the sample?  What if I wanted to determine the 5%  of stoneflies that exhibited behavioral characteristics, that differentiated them from the other 95%?  Suddenly we have a problem.  The source of that problem is a nervous system.  The underlying reality of most even slightly complicated nervous systems is that they will never have the regularity of a physical system.  They have evolved not to.  Regularity in a nervous system locking it into a physically predictable system is not in any way adaptive for any animal that needs to forage and reproduce.  It is the kiss of death.

But is gets complicated at additional levels.  The human brain is highly evolved to have significant processing power.  At another level, there are theoretical concerns about whether it is possible to ever to map behaviors and psychiatric symptoms directly onto some neurobiological system.  Unlike my experiment 1 above we are rarely interested in looking at only life or death as the outcome variable.  The variables that will allow us to study different populations are going to be much more complex than grossly observed behaviors.  There is a complicated nervous system between those behaviors and the environment.

Is psychiatry really not a science because it is complex and attempts to deal with the complicated phenomena associated with the human brain?   Should we ever be concerned about 1:1 mappings of psychiatric disorders onto a specific genetic or neurobiological defect?  Is it possible that a human nervous system is so complex that it is unrealistic to expect that this might happen?

Unlike Brook's theme nobody is a "Hero of Uncertainty".  Uncertainty is the expected condition and one that every psychiatrist should be comfortable with.  Psychiatry and the associated neurosciences will never be reduced to the predictable calculation of a physical system and that has nothing to do with one being a more prestigious science.  It has to do with evolution and complexity.  It has to do with what philosophers call the "demarcation problem" between what is and what is not science.  More to come on that in the near future.

On the Validity of Pseudopatients


Every now and again the detractors and critics of psychiatry like to march out the results of an old study as "proof" of the lack of validity of psychiatric diagnoses.  In that study,  8 pseudopatients feigned mental illness to gain admission to 12 different psychiatric hospitals.  The conclusion of the study author was widely seen as having significant impact on the profession, but that conclusion seems to have been largely retrospective.  I started my training about a decade later and there were no residuals at that time.  I learned about the study largely through the work of antipsychiatrists and psychiatric critics.

Several obvious questions are never asked or answered by the promoters of this test as an adequate paradigm.  The first and most obvious one is why this has not been done in other fields of medicine.  It would certainly be easy to do.  I could easily walk into any emergency department in the US and get admitted to a Medicine or Surgical service with a faked diagnosis.  I know this for a fact, because one of the roles of consulting psychiatrists to Medicine and Surgery services is to confront the people who have faked illness in order to be admitted.  Kety (9) uses a more blunt example in response to the original pseudopatient experiment (1):

"If I were to drink a quart of blood and, concealing what I had done, come to the emergency room of any hospital vomiting blood, the behavior of the staff would be quite predictable. If they labeled and treated me as having a bleeding peptic ulcer, I doubt that I could argue convincingly that medical science does not know how to diagnose that condition. "(9)

I also know that this happens because of the current epidemic of prescription opiate abuse and the problem of drug seeking and being successful at it.  An estimated 39% of diverted drugs (7) come from "doctor shopping."  By definition that involves presenting yourself to a physician in a way to get additional medications.  In the case of prescription opioids that usually means either faking a pain disorder or misrepresenting pain severity.  So it is well established that medical and surgical illness well outside of the purview of psychiatry can be faked.  And yet to my knowledge, there is hardly any research on this topic and nobody is suggesting that medical diagnoses don't exist because they can be faked.  Does that mean the researchers consider the time of these other doctors too valuable to waste?  More likely it did not fit a preset research agenda.

The second obvious question has to do with conflict of interest.  It is currently in vogue to suggest that psychiatrists are swayed in their prescribing practices by incentives ranging from a free pen to a free meal.  Compensation as a company employee or to give lectures is also thought of as a compromising incentive. The free pen/free meal incentive is pretty much historical at this time.  What about intentionally misrepresenting yourself?  What is the conflict of interest involved at that level and how neutral can you stay when you are trying to escape detection in order to prove a point?  A vague script like a mono-symptomatic presentation of schizophrenia should suggest that the intent is to escape detection.  How should a person with a vague script act when they are face to face with a real clinician?  The logical conclusion is that they would be as evasive as possible even if they were adhering to that protocol.

The bottom line is that the pseudopatient experiments were seriously flawed out of the box.  Continuing to promote them as meaningful reflects a serious lack of scholarship in reading the relevant literature and a need to suspend the reality that in fact mental illness does exist, that distinctions can be made among various types of mental illness, and that those distinctions are useful to psychiatrists trying to help people with those problems.
