Facial Distortions and Prosopometamorphopsia | Brad Duchaine

We begin by imagining a world where children are separated by sex at birth and raised without exposure to traditional gender norms. We debate whether gender incongruence is a result of nature or social conditioning. We discuss gender affirming care for children, highlighting the complexity of diagnosing gender dysphoria amidst co-occurring psychiatric conditions and the potential influence of social contagion. Key insights include questioning the lack of robust evidence for the efficacy of puberty blockers and cross-sex hormones, and the need for comprehensive psychosocial care before considering medical transition. The Cass Review was released after we recorded our conversation, but we address similar concerns.   00:00 Introduction to the Thought Experiment 00:10 Exploring Gender Segregation and Its Impacts 02:22 Debating the Existence of Gender Incongruence 03:28 The Social Construction of Gender and Its Medical Implications 04:48 Sexual Orientation in a Segregated Society 13:37 Challenging the Medicalization of Gender Diversity 25:26 Transracialism and Personal Identity Choices 31:41 Medical Risks and Ethical Dilemmas in Gender Transition 41:38 Exploring the Regulation of Cross-Sex Hormones 42:11 The Uncertainty of Medical Interventions and Autonomy 44:49 The Complexities of Gender Dysphoria Treatment 45:43 Evaluating the Risks and Benefits of Paediatric Transition 48:39 The Debate on Consent and Medical Ethics 51:38 Addressing Comorbidities in Gender Dysphoria Treatment 58:45 The Role of Social Phenomena in Gender Dysphoria 01:11:17 Examining the Evidence and Ethics of Puberty Blockers --- Send in a voice message: https://podcasters.spotify.com/pod/show/braininavat/message

Peter Singer delves into difficult ethical questions regarding animal rights, the morality of factory farming, and difficult human-related ethical dilemmas. Singer discusses his views as a consequentialist, examining the impact of our choices on animal suffering, the ethical considerations around organ donation from anencephalic children, and the broader implications of such decisions. What are the moral implications of eating meat from factory farms versus ethically raised animals, and cannibalism under hypothetical scenarios with no harm to others? Singer emphasizes the need for considering the consequences of our actions, shedding light on the pressing need to reform our food production systems and make more ethical choices in our daily lives.   Peter Singer’s Substack: https://substack.com/profile/4270932-peter-singer Peter Singer’s YouTube channel: https://www.youtube.com/@peter_singer Peter Singer’s book, ‘Animal Liberation Now’: https://www.amazon.com/Animal-Liberation-Now-Definitive-Classic/dp/0063226707   00:00 A Philosophical Dive into Animal Rights with Peter Singer 00:12 Exploring the Ethical Dilemmas of Human and Animal Lives 01:59 The Complexities of Organ Donation from Anencephalic Children 03:57 Comparing Human and Animal Rights in Medical Contexts 06:08 Consequentialism and Individual Case Analysis in Ethics 07:42 The Ethical Quandaries of Parental Consent and Medical Decisions 15:54 Navigating the Slippery Slope of Euthanasia and Assisted Dying 25:41 The Ethical Considerations of Eating Meat and Factory Farming 33:29 The Harsh Realities of Factory Farming 34:45 Ethical Considerations and the Nature of Animal Suffering 36:50 Addressing Common Objections to Animal Rights 41:12 The Impact of Individual Choices on Animal Suffering 43:43 The Role of Vegetarianism and Veganism in Reducing Demand for Meat 01:00:46 Exploring the Ethical Implications of Consuming Expired or Discarded Meat 01:04:50 Concluding Thoughts and Reflections --- Send in a voice message: https://podcasters.spotify.com/pod/show/braininavat/message

In this special episode of Brain in a Vat, Brad Duchaine from the Psychological and Brain Sciences Department at Dartmouth discusses prosopometamorphopsia (PMO) – a condition where individuals see distorted faces. The episode explores various manifestations of PMO, including seeing demonic features, dragons, or entirely different faces, and distinguishes it from prosopagnosia (face blindness). It delves into the neurological basis of PMO, touching upon structural and functional differences in the brains of those affected. We discuss the significant impact PMO and prosopagnosia have on individuals' social interactions and quality of life, as well as potential management techniques such as using glasses or colored lights to reduce distortions.   00:00 Introduction and Guest Presentation 00:20 Exploring the Case of Face Distortion 03:19 Understanding the Nature of Distortions 05:49 Comparing Prosopagnosia and PMO 07:17 The Role of Visual System in Face Recognition 10:01 Impact of Face Recognition on Social Interactions 14:16 The Spectrum of Face Recognition Abilities 16:20 The Role of AI and Hallucinations in Face Recognition 23:48 Understanding the Diagnosis of Face Recognition Disorders 30:20 Understanding Prosopagnosia: Prevalence and Characteristics 31:59 The Mystery of PMO: Prevalence and Need for More Research 32:46 Exploring the Impact of Prosopagnosia and PMO on Social and Sexual Relationships 33:23 The Intersection of PMO and Other Psychiatric Conditions 37:03 The Struggles and Challenges of Living with Prosopagnosia and PMO 41:02 Potential Treatments and Coping Mechanisms for PMO 51:22 The Neurological Basis of PMO and Prosopagnosia 54:51 Testing and Characterizing PMO: A Deep Dive into Research Methods 59:54 Understanding the Perception and Processing of Faces in PMO --- Send in a voice message: https://podcasters.spotify.com/pod/show/braininavat/message

We welcome back Nadine Strossen for a comprehensive discussion about pornography and free speech. She highlights points from her re-released book 'Defending Pornography', explaining why she supports the freedom of sexual expression. Her thought experiment is about a respected academic who makes adult videos, raising questions about personal freedom, professional reputability, and potential harm to his university. She also explores the complex relationship between pornography, liberty, and equality, emphasizing that context matters when considering whether freedom of speech overrides other concerns. The conversation also touches on whether pornography subordinates women, Nadine underlines that she defends the right to pornography not because she is an aficionado, but because she believes in individual choices.
