A survey of 314 professional philosophers found that personality traits and demographics do not predict philosophical views, but some psychological traits do. Higher numeracy predicted physicalism, naturalism, and consequentialism. Lower well-being and higher mental illness predicted hard determinism. Use of psychedelics and marijuana predicted non-realist and subjectivist views on morality and aesthetics. Transformative or self-transcendent experiences predicted theism and idealism. 68% of the philosophers surveyed indicated that such empirical findings have philosophical value.
A workshop on psychedelic ethics, the first Hopkins-Oxford Psychedelic Ethics (HOPE) meeting, was held in August 2023 at the University of Oxford to address ethical issues surrounding psychedelics. The organizers (BDE, DBY, EJ) aimed to foster interdisciplinary discussion on topics such as informed consent, therapeutic use, and societal implications. The report outlines the workshop's structure, key themes, and proposed guidelines for ethical research and practice in the field.
