Mystical experience in the Bayesian brain
Mystical experiences are among the most extraordinary and meaningful experiences one can have. While such experiences have been studied for more than a century, it is still an open question how the brain can produce them. The present paper provides a possible answer by examining mystical experience from the lens of the REBUS hypothesis—a theory that explains the neurocognitive mechanisms of psychedelics in the Bayesian brain. Since psychedelics h…
Mental disorder and its treatment as a transformative experience
According to L.A. Paul, undergoing an experience is transformative if we learn something we cannot learn without having the experience and if it substantially changes our point of view. While the implications of transformative experiences have primarily been discussed in the context of rational choice, their underlying concept has also proven fruitful in the context of unchosen occurrences. The present paper examines mental disorder and its treat…
Breaking Up Rationally
The end of a long-term romantic relationship ranks among the most stressful and momentous events in life. Thus, the decision of whether to break up with someone whom one has been with for many years should generally be made very carefully. Unfortunately, decision theory is often thought to be unable to provide rational guidance in such high-stake life choices due to the outcomes’ presumed transformative character. The present paper shows how agen…
Psychedelics beyond medicine
The current revival of interest in classic psychedelics and other psychoactives such as ketamine and MDMA, coupled with changes to their regulatory status in many jurisdictions, necessitates rigorous ethical guidelines both within and beyond clinical and scientific contexts. This paper examines crucial ethical, philosophical, and policy considerations needed to ensure psychedelic use across various settings remains equitable, beneficial, consensu…
Stereotypes and self-fulfilling prophecies in the Bayesian brain
Stereotypes are often described as being generally inaccurate and irrational. However, for years, a minority of social psychologists has been proclaiming that stereotype accuracy is among the most robust findings in the field. This same minority also opposes the majority by questioning the power of self-fulfilling prophecies and thereby the construction of social reality. The present paper examines this long-standing debate from the perspective o…
Psychedelic Ethics
The reemergence of serotonergic psychedelics in clinical research and practice has sparked numerous debates within bioethics. This paper aims to provide an overview of the key issues discussed in the emerging field of psychedelic ethics. It organizes these issues into four (partly overlapping) categories: (1) the implementation and execution of psychedelic research and practice, (2) the ethics of belief as applied to PAT, (3) discrimination and i…
How to Make Psychedelic-Assisted Therapy Safer
Classic serotonergic psychedelics are experiencing a clinical revival, which has also revived ethical debates about psychedelic-assisted therapy. A particular issue here is how to prepare and protect patients from the vulnerability that the psychedelic state creates. This article first examines how this vulnerability manifests itself, revealing that it results from an impairment of autonomy: psychedelics diminish decision-making capacity, reduce …
The role of expectations in transformative experiences
According to L. A. Paul, the subjective value of an outcome is normally assessed by running a cognitive model of what it would be like if that outcome were to occur. However, cognitive models, along with the expectations in which they result, are unreliable for application to transformative experiences because we cannot know what it would be like for an outcome to occur if we have never experienced it before. This paper argues that despite their …
Transformative Experience
Since its publication in 2014, L. A. Paul's book Transformative Experience has sparked many discussions in philosophy and beyond. Her main argument is that experiences we have not had before can transform us epistemically (i.e., we learn something we could not learn without the experience) and personally (i.e., our point of view changes radically). This has implications for decision theory in particular, but also for other fields. The present pap…
With great power comes great vulnerability
Psychedelics are experiencing a renaissance in mental healthcare. In recent years, more and more early phase trials on psychedelic-assisted therapy have been conducted, with promising results overall. However, ethical analyses of this rediscovered form of treatment remain rare. The present paper contributes to the ethical inquiry of psychedelic-assisted therapy by analysing the ethical implications of its therapeutic mechanisms proposed by the re…
The Role of Certainty in a Two-Person Volunteer’s Dilemma
In the standard volunteer’s dilemma (VoD), a single prosocial act (i.e., volunteering) yields the optimal overall outcome. Whereas the volunteer’s outcome is certain, the defector’s outcome depends on what others do. This research addressed the confounding of prosocial responses with uncertainty avoidance in the standard VoD. In Experiment 1, participants ( N = 102) considered 18 hypothetical one-shot two-person VoD scenarios with certain, risky,…
Rational transformative decision-making
According to L. A. Paul (2014), transformative experiences pose a challenge for decision theory, as their subjective value is not epistemically accessible. However, several authors propose that the subjective values of options are often irrelevant to their ranking; in many cases, all we need for rational transformative decision-making are the known non-subjective values. This stance is in conflict with Paul’s argument that the subjective value ca…
Dissecting Discrimination
In this book discrimination gets descriptively examined via decision theory. It studies the facets and roots of taste-based and statistical discrimination This is an open access book.
How Psychedelic-Assisted Treatment Works in the Bayesian Brain
Psychedelics are experiencing a renaissance in clinical research. In recent years, an increasing number of studies on psychedelic-assisted treatment have been conducted. So far, the results are promising, suggesting that this new (or rather, rediscovered) form of therapy has great potential. One particular reason for that appears to be the synergistic combination of the pharmacological and psychotherapeutic interventions in psychedelic-assisted t…
A rational route to transformative decisions
According to Paul (Transformative experience, 1st edn, Oxford University Press, 2014), transformative experiences pose a challenge to decision theory since their value cannot be anticipated. Building on Pettigrew’s (in: Lambert, Schwenkler (eds) Becoming someone new: essays on transformative experience, choice, and change, Oxford University Press, pp 100–121, 2020) redescription, this paper presents a new approach to how and when transformative d…
