Honest questions examining our intellectual sinfulness

Pär SegerdahlWhy should we hold our philosophical tradition in high esteem? Why should we admire Socrates and other great thinkers? Because they strengthened reason? Because they taught humanity to set emotions aside and instead purify facts and logic?

If that were true, we should admire the philosophers for armoring humanity. For turning us into clever neurotics without contact with our emotional life.

I believe the greatness of these philosophers is more simple, humble and human. They were embarrassingly aware of their own intellectual sinfulness. They had the courage to confess their sins and to examine them closely. They had the courage to know themselves.

That sincere humility, I believe, marks true thinkers from all parts of the world. Just as Socrates, in the middle of a discourse, could hear an inner voice stop him from speaking with intellectual authority on some topic, Lao Tzu saw it as a disease to speak as if we knew what we do not know.

These genuine thinkers hardly spoke with intellectual certainty. At least not in their most creative moments. They probably felt ashamed of the cocksure voice that marks many of our intellectual discussions about prestigious topics. They probably spoke tentatively and reasoned hesitantly.

We are all fallible. Philosophy is, at heart, intense awareness of this human fact. How does such awareness manifest in a thinker? Usually through questions that openly confess that, I know that I do not know. A philosophical inquiry is a long series of confessions. It is a series of sincere questions exposing a deep-rooted will to control intellectually the essence of various matters. The questions become clearer as we come to see more distinctly how this will to power operates in us. When we see how our desire to dictate intellectually what must be true, blinds us to what is true.

Do you and I, as academics, dare to admit our intellectual sinfulness? Do we dare to confess that we do not know? Do we have the courage to speak tentatively and to reason hesitantly?

I believe that we would do a great service to ourselves and to humanity if we more often dared to speak openly in such a voice. However, we are facing a difficulty of the will. For there is an expectation that researchers should master facts and logic. Surely, we are not paid to be ignorant and irrational. Therefore, must we not rather disseminate our knowledge and our expertise?

Of course! However, without awareness of our intellectual sinfulness, which could stop Socrates in the middle of a sentence, we run the risk of contributing to the disease that he treated in himself. We display not only what we happen to know, but also a shiny facade that gives the impression that we control the truth about important matters.

In short, we run the risk of behaving like intellectual Pharisees, exhibiting an always well-polished surface. Below that surface, we wither away, together with the society to which we want to contribute. We lose touch with what truly is alive in us. It succumbs under the pressure of our general doctrines about what must be true. Intellectualism is a devastating form of fact denialism. In its craving for generality, it denies what is closest to us.

Do not armor yourself with rationalism as if truth could be controlled. Instead, do what the greatest thinkers in the history of all of humanity did. Open yourself to what you do not know and explore it in earnest.

You are vaster than your imagined knowledge. Know yourself!

Who belongs to us?

Pär SegerdahlBioethics has a problem with human beings, the philosopher Roland Kipke writes. It must ask who belongs to our moral community. Who has rights? Who has human dignity? Who has the moral status usually attributed to healthy adult humans? Who has the right to life?

The question is: Who belongs to us? Are human embryos included in the community? Newborns? Those with advanced dementia? Intelligent animals?

A common response to the question is to propose a philosophical criterion. Two positions dominate in bioethics. One includes all biological human beings, thereby embryos, newborns and those with advanced dementia. Everyone who belongs to the species Homo sapiens belongs to the moral community.

The second position holds that species membership is irrelevant. Instead, the focus is on mental capacities that one holds characterize a “person.” For example, rationality and self-awareness. This excludes embryos, newborns and those with advanced dementia from the community. However, a rational chimpanzee may enter. All persons belong to the moral community, regardless of species affiliation.

Kipke shows how both criteria compel us to answer the question “Who belongs to us?” in ways that contradict most people’s moral intuitions. We might accept this if the positions could be justified by strong arguments, he says. However, such arguments are missing.

What should a poor philosophical gatekeeper do then? Who should be admitted into the community? Who should be kept out?

The solution to the gatekeeper’s dilemma, Kipke suggests, is our ordinary concept of the human. When we talk about “humans,” we usually do not use the scientific concept of a biological species. Our everyday concept of a human already has moral dimensions, he points out. We cannot see a human being without seeing a living person belonging to our community. According to this third position, all humans belong to the moral community.

The only problem is that the gatekeeper needs a criterion to distinguish the human members of the community. It is true that we have everyday uses of the word “human.” It is also true that we normally have no difficulties in distinguishing a human being. However, do these uses really contain a criterion suitable for more philosophical gatekeeper tasks? They do, according to Kipke. He holds that there is a characteristic “living human gestalt or the form of the body,” especially the face, which easily allows recognition of a human being, even when she is seriously injured and deformed.

The “living human form” would thus be the criterion. This form makes us equals in the moral community.

Kipke’s article is philosophically exciting and his criticism of the two dominant positions is revealing. Personally, I nevertheless find the still dominant preoccupation with the question “Who belongs to us?” somewhat terrifying, and perhaps even inhuman. Bioethics treats human concerns about, for example, genetics and stem cell research. Admittedly, people often express their concerns in the form of boundary issues. People who worry about the destruction of embryos in stem cell research, for example, can talk about the embryo as a human individual or as a potential person. However, addressing their worries by suggesting that our common language contains a criterion that has the authority to separate the members of the moral community will probably not still the minds of such worried and perhaps even angry humans. They need a lot more attention. Perhaps it turns out that the intellectual boundary issue concealed the living source of their concerns and made it impossible to treat the problem at its source.

I believe we need a bioethics that responds to moral concerns more humanly and communicatively than only as philosophical boundary issues. Could we not use our ordinary language to think together about the issues that worry us? To refer to an ordinary concept of the human as an arbiter that supposedly dictates the answers to bioethical boundary issues seems characteristic of a smaller community: one that is professionally preoccupied with philosophical boundary issues.

Is that not placing bioethics before life? Is it not putting the cart before the horse?

Bioethics without doctrines

Pär SegerdahlEver since this blog started, I have regularly described how bioethical discussions often are driven by our own psychology. On the surface, the debates appear to be purely rational investigations of the truthfulness of certain claims. The claims may be about the risks of genetically modified organisms (GMOs), the private nature of genetic information, the moral status of the human embryo, or the exploitation of egg donors for stem cell research. The topics are, as you probably hear, sensitive. Behind the rational surface of the debates, one can sense deeply human emotions and reactions: fear, anger, anxiety.

Have you ever been afraid? Then you know how easily fear turns into anger towards what you think causes your fear. What happens to the anger? Anger, in turn, tends to express itself in the form of clever arguments against what you think is causing your fear. You want to prove how wrong what frightens you is. It must be condemned, it must cease, it must be prohibited. This is how debates often begin.

The debates hide the emotions that drive them. Fear hides behind anger, which hides behind clever arguments. This hiding in several steps creates the shiny rational surface. It sounds like we were discussing the truth of purely intellectual doctrines about reality. Doctrines that must be defended or criticized rationally.

As academics, we have a responsibility to contribute to debates, to contribute with our expertise and our ability to reason correctly. This is good. Debates need objectivity and clear logic. The only risk is that sometimes, when the debates are rooted in fear, we contribute to hiding the human emotions even more deeply below the rational surface. I think I can see this happening in at least some bioethical debates.

What we need to do in these cases, I think, is to recognize the emotions that drive the debates. We need to see them and handle them gently. Here, too, objectivity and clear logic are required. However, we do not direct our objectivity at pure doctrines. Rather, we direct it more thoughtfully at the emotions and their expressions. Much like we can talk compassionately with a worried child, without trying to disprove the child as if the child’s worries were deduced from false doctrines about reality.

If our objectivity does not acknowledge emotions, if it does not take them seriously, then the emotions will continue to drive endlessly polarizing debates. But if our objectivity is kindly directed to the emotions, to the psychological engine behind the polarization, then we can pause the sensitive mechanism and examine it in detail. At least we can make it react a little slower.

We habitually distinguish between reason and feeling. As soon as a conflict emerges, we hope that reason will pick out the right position for us. We do not consider the possibility that we can direct reason directly to the emotions and their expressions. It is as if we thought that feelings are so irrational that we must suppress them, should hide them. As parents, however, this is precisely how we reason wisely: We talk to the child’s feelings. Sometimes we need to handle our own feelings the same way. We need to acknowledge them and take good care of them.

In such a compassionate spirit, we can turn our objectivity and our wisdom towards ourselves. Not just in bioethics, but everywhere where human vulnerability turns into relentless argumentation.

By gently dissolving the doctrines that lock the positions and reinforce the hidden emotions, we can begin the process of undoing the mental deadlocks. Then we may talk more clearly and objectively about genetics and stem cell research.

Learning from the difficulties

Pär SegerdahlIn popular scientific literature, research can sometimes appear deceptively simple: “In the past, people believed that … But when researchers looked more closely, they found that …” It may seem as if researchers need not do much more than visit archives or laboratories. There, they take a closer look at things and discover amazing results.

There is nothing wrong with this popular scientific prose. It is exciting to read about new research results. However, the prose often hides the difficulties of the research work, the orientation towards questions and problems. As I said, there is nothing wrong with this. Readers of popular science rarely need to know how physicists or sociologists struggle daily to formulate their questions and delve into the problems. Readers are more interested in new findings about our fascinating world.

However, there are academic fields where the questions affect us all more directly, and where the questions are at the center of the research process from beginning to end. Two examples are philosophy and ethics. Here, identifying the difficult questions can be the important thing. Today, for example, genetics is developing rapidly. That means it affects more people; it affects us all. Genetic tests can now be purchased on the internet and more and more patients may be genetically tested in healthcare to individualize their treatment.

Identifying ethical issues around this development, delving into the problems, becoming aware of the difficulties, can be the main element of ethics research. Such difficulty-oriented work can make us better prepared, so that we can act more wisely.

In addition, ethical problems often arise in the meeting between living human beings and new technological opportunities. Identifying these human issues may require that the language that philosophy and ethics use is less specialized, that it speaks to all of us, whether we are experts or not. Therefore, many of the posts on the Ethics Blog attempt to speak directly to the human being in all of us.

It may seem strange that research that delves into questions can help us act wisely. Do we not rather become paralyzed by all the questions and problems? Do we not need clear ethical guidelines in order to act wisely?

Well, sometimes we need guidelines. But they must not be exaggerated. Think about how much better you function when you do something for the second time (when you become a parent for the second time, for example). Why do we function better the second time? Is it because the second time we are following clear guidelines?

We grow through being challenged by difficulties. Philosophy and ethics delve into the difficulties for this very reason. To help us to grow, mature, become wiser. Individually and together, as a society. I do not know anyone who matured as a human being through reading guidelines.

In-depth critique of dynamic consent

Pär SegerdahlBiobanks are getting bigger and the human biological samples that are stored in the freezers have increasingly long-term utility for research. The samples can be used not only in one study, but also in several different studies. Not only in today’s research, but also in future research. This creates research ethical tensions.

Ethics requires that research participants are informed about and consent to the specific purpose of the project they are asked to participate in. However, when a large-scale biobank is being constructed, such specific information cannot be provided. Future research purposes do not exist yet and cannot be specified. Not until researchers in the future design new studies. How then can biobank research be conducted ethically?

In recent years, a technical solution has been launched: Transform research participants into users of new information and communication technologies (ICT)! Through their computers, tablets or cell phones, they can continuously be informed about new research projects. Sitting in front of their screens, they can give specific consent, or refrain from it, as new projects take shape and researchers apply for access to the biobank’s collected samples. The solution is named dynamic consent.

Dynamic consent certainly seems like an ingenious technical solution to the ethical tensions surrounding today’s increasingly long-term and large-scale biobanks. Moreover, is it not also democratic and politically progressive? Does it not give research participants greater power over the research? Is it not as if all these hundreds of thousands of donors of biological material voted on the direction of future research? Simply by deciding on the use of their own samples.

I recently read an in-depth critique of this belief in a technical solution to the ethical problem. The article is written by Alexandra Soulier at CRB, and focuses on ethical and political consequences of turning research participants into ICT users. Here are some comments that I want to highlight:

The public good that we associate with research is not the sum of isolated individuals’ private preferences in front of their computer screens. Dynamic consent is in tension with the collective and long-term nature of biobank research, and with the notion of the public good which research aims at.

If individual ICT users’ private decisions replace the joint discussions, considerations and functions of ethical committees, the governance of biobanks can be impaired. This, in turn, poses a risk to the participants themselves.

Dynamic consent might transform research participants into seducible audiences. Researchers may want to sell their projects to these audiences through clever communication strategies. Research participants are then treated as manipulable rather than as a rational public to be convinced.

Dynamic consent is not a referendum. Research participants do not vote on research policy issues. They only express their private preferences about their own research participation, project by project, without regard to any research policy implications for the long-term activities of the biobank.

Research participants who do not want to spend years in front of the screen in order to make decisions in real time about their participation in biobank research may feel forced to choose the option (through their technical device) to give exactly the open consent to future research that originally was considered problematic. How can what was considered to be the ethical problem be allowed to be included in the seemingly smart solution?

In summary, the proposed individual-centered technical solution to the ethical challenges of biobank research short-circuits the possibility of jointly taking political and ethical responsibility for these challenges.

I regret that I cannot do justice to Alexandra Soulier’s subtle discussion. I have not read such in-depth criticism in a long time. Read it!

Transhumanism purifies human misery

Pär SegerdahlThe human is a miserable being. Although we are pleased about the new and better-paid job, we soon acquire more costly habits, richer friends, and madder professional duties. We are back to square one, dissatisfied with life and uncomfortable with ourselves. Why can life never be perfect?

Discontent makes us want to escape to better futures. We want to run away from worries, from boredom, from disease, from aging, from all the limitations of life, preferably even from death. We always rush to what we imagine will be a better place. As often as we find ourselves back to square one.

The eternal return of discontent thus characterizes the human condition. We imagine that everything will be perfect, if only we could escape from the present situation, which we believe limits us and causes our discontent. The result is an endless stream of whims, which again make us feel imprisoned.

Always this square one.

Transhumanism is an intellectual revivalist movement that promises that AT LAST everything will be perfect. How? Through escaping from the human herself, from this deficient creature, trapped in a biological body that is limited by disease, aging and death.

How can we escape from all human limitations? By having new technology renew us, making us perfect, no longer suffering from any of the biological limitations of life. A brave new limitless cyborg.

Who buys the salvation doctrine? Literally some of the richest technology entrepreneurs in the world. They have already pushed the boundaries as far as possible. They have tried all the escape routes, but the feeling of limitation always returns. They see no other way out than escaping from EVERYTHING. They invest in space technology to escape the planet. They invest in artificial intelligence and in the deep-freezing of their bodies, to escape the body in the future, into supercomputers that AT LAST will save them from ALL life’s limitations, including disease, aging and death.

Do you recognize the pattern? Transhumanism is human misery. Transhumanism is the escapism that always leads back to square one. It is the dream of a high-tech quantum leap from dissatisfaction. What does paradise look like? Like a high-tech return to square one.

We need new technology to solve problems in the world. When coupled with human discontent, however, technology reinforces the pattern. Only you can free yourself from the pattern. By no longer escaping to an ideal future. It does not work. Running to the future is the pattern of your misery.

Transhumanism is the intellectual purification of human misery, not the way out of it.

People want to be able to influence the risk

Pär SegerdahlWe need to do research to know what people think is important in genetic risk information. What they prefer to know. But how do we find out? One way is to ask people to answer questionnaires.

One problem with questionnaires is that they ask one thing at a time. Do you prefer a hotel room with a sea view when you are on vacation? You probably answer yes. But do you prefer the sea view even if the room is above the disco, or costs 500 EUR per night? If you only ask one thing at a time, then it is difficult to know how different factors interact, how important they are relative to each other.

One way to get past this limitation is to ask people to choose between two alternatives, where the alternatives have several different attributes.

  • Hotel room A: (1) View: sea (2) Price: 200 EUR per night (3) Distance to the center: 30 minutes walk (4) Sound level: high.
  • Hotel room B: (1) View: parking (2) Price: 100 EUR per night (3) Distance to the center: 40 minutes bus ride (4) Sound level: low.

Which room do you choose, A or B? The choice tasks are repeated while the attributes are varied systematically. In this way, one can learn more about what people prefer, than through a regular questionnaire. One can see how different attributes interact and which attributes are more important than others are. One can also calculate how much more important an attribute is over another.

The same kind of study can be done about genetic risk information instead of hotel rooms. Jennifer Viberg Johansson at CRB recently did such a study. Four attributes of the risk information were varied in the choice tasks:

  • (1) Type of disease (2) Probability of developing disease (3) Preventive opportunities (4) Effectiveness of the preventive measure.

Which of the attributes was most important to the people who participated in the study? How much more important was it?

It turned out that the most important attribute was the effectiveness of the preventive measure. If the information contained an effective preventive measure, the respondents clearly preferred that information. The effectiveness of the preventive measure was twice as important to know, compared to the probability of developing the disease.

Apparently, it is important for people to be able to influence the risk. One conclusion in the study is that when risk information says that there is an effective preventive measure, then risk communication can focus more on the preventive measure than on the probability of developing disease.

The method is called, “Discrete Choice Experiment.” If you want to look more closely at the method and get more results, read Jennifer Viberg Johansson’s article in Genetics in Medicine.

How about personally optimized treatment?

Pär SegerdahlIt is well known that patients who are asked to participate in cancer trials are tempted by the therapeutic misconception. They believe they are offered a newer and better treatment, when in fact it is about research into an untested treatment. When researchers use genetic tests to develop personalized oncology, even more misconceptions can arise. I will soon explain. But first, what is personalized cancer treatment? Here is an example.

Patients whose tumor is to be operated may undergo preparatory radiation or chemotherapy. Since the preparatory therapy has severe side effects, one wants to avoid giving it to patients whose tumors do not respond to it. The challenge is to distinguish patients who respond to treatment from patients who do not. This is to be accomplished through, among other things, genetic tests on the tumor cells. If this works, you can develop personalized cancer treatment. Patients with the “right” tumor cell genetics receive the preparatory therapy, while patients who, according to the genetic tests, only get the side effects, with no effect on tumor growth, do not receive the therapy.

What are the misconceptions that can arise in patients who are asked to participate in research on personalized cancer treatment? Here are some examples.

Patients who are told that the researchers will do genetic tests can feel a genetic responsibility to participate, considering their children and grandchildren. They believe the test results may be relevant to close relatives, who may have the same disease genes. However, the tests are done on mutated tumor cells and therefore say nothing about inherited cancer risk. A sense of genetic responsibility can thus be triggered by the word “genetics” and create a genetic misconception of research in personalized oncology.

Other misconceptions have to do with the positive language used to describe personalized medicine. One talks about personally “optimized” treatments, about “tailored” treatments, about treatments that are adapted “to the individual.” This language use is not intended to mislead, but it is easy to see how words such as “optimization” can cause patients to believe that research participation means special treatment benefit.

The biggest challenge is perhaps to explain the research purpose behind the positive language. The aim is to be able in the future to distinguish between patients, to “stratify” them, as it less positively is called. Personally optimized care actually means that some patients do not receive certain treatments. This is, of course, reasonable if genetic tests can show that they have no benefit from the treatments but only get the side effects. However, what do cancer patients themselves say about stratified cancer treatment, where some patients are identified as non-responders and therefore are not offered the same treatment as other patients? Finally, do participants understand that “tailored treatment” is a future goal of the study and not something they are offered to try?

Communication with patients recruited for studies in personalized oncology faces many challenges, as patients are tempted by even more misconceptions than just the well-known therapeutic misconception.

Genetic risk information: lines and stage directions

Pär SegerdahlOutside of their practical contexts, simple messages quickly lose their meaning. Recall what it is like to find an old Post-it Note: “Don’t forget the disk!” – What disk? The risk is great that we invent a context. Incomprehensible messages awaken our imagination.

Similarly, messages about genetic risk need practical contexts that make the information meaningful and prevent nightmarish imaginations. The information needs to become part of a larger drama. Otherwise, we begin to fantasize: “Greatly increased risk of breast cancer.” – What do they mean, “greatly increased”? What do they mean, “breast cancer”? What do they mean, “risk”?

The difficulty of understanding and benefitting from genetic risk information is probably partly due to lack of context. The potential for generating risk information is growing rapidly. All this information is waiting for its dramas: contexts where people can ask concrete questions and get practical advice. Educational methods for explaining percentages cannot replace the loss of context. People who get genetic risk information need to know more about the disease they are at risk of developing. They may want to know if they should notify the employer of the risk. They may want to know if something can be done to reduce the risk. They may want to know what it is like to live with the disease, or with the risk of getting it. How is the family affected? Can you work having the disease? Should one worry or is it reasonable to hope that one will not get the disease? And so on.

In short, well-functioning genetic risk information has two dimensions. First, an individual dimension: “You have a greatly increased risk of…” Secondly, a general dimension: Practical instructions on a wide variety of issues that people need to know more about, and about which they otherwise begin to fantasize.

To speak the language of the theater: The individual dimension (the simple risk message) is the lines. The general dimension is the stage directions. Genetic risk information consists of both lines and stage directions.

When we discuss whether genetic risk information empowers people to influence their future health or just worries them, when we discuss the difficulty of understanding risk information, we should be clearly aware of these two dimensions of the information. Are we discussing the lines or the stage directions? Or are we discussing the lines together with the stage directions?

Which dimension of genetic risk information is most relevant to the individual? Perhaps the lines are merely a reason for moving on to the stage directions. The dramatic risk lines may speak mainly to the healthcare staff, while the individual above all needs the stage directions.

One could not work at a theater without distinguishing between lines and stage directions. Perhaps something similar applies to genetic risk information.

Pragmatic trials without informed consent?

Pär SegerdahlRandomized controlled trials (RCTs) are considered to be the gold standard for determining a causal effect of medical interventions. To achieve this aim, possible confounding factors must be avoided. This implies excluding many patients from participating in the trial, for example, patients with concomitant conditions. A negative consequence of these exclusions, however, is limited generalizability. Studying the artificially uniform participant group, you will be able to determine a causal effect, but you will know much less about real-life treatment outcomes in the population where the intervention actually will be used.

Further artificiality is created by the written informed consent procedure, which excludes even further patients from participating in the trial. Moreover, because they know they participate in a clinical trial, participants may change their behavior.

All this points to the importance of so-called pragmatic randomized controlled trials. In such trials, the effectiveness of two approved and routinely prescribed medicines are compared in normal clinical practice. This avoids most of the artificiality of RCTs and significantly improves generalizability and practical clinical relevance. Randomization is still required for scientific purposes, however, and written informed consent is an ethical obligation.

The demand for written informed consent is an obstacle to pragmatic trials. By creating, once again, artificial selection of patients, results continue to be less generalizable, which detracts from the whole point of conducting pragmatic trials. In a recent paper in the BMJ, twelve authors, among them, Stefan Eriksson at CRB, therefore argue that “EU clinical trial regulations should be revised to allow the waiver or modification of informed consent in low risk pragmatic trials.”

Some would consider this suggestion to be controversial. We need to keep in mind, however, the extremely low risks of studies that compare standardly prescribed medicines in normal clinical practice. We need to balance that low risk against the enormous social value of generalizable findings in evidence-based medicine.
