Evolving Psychiatry

Stories abound in evolutionary psychology and psychiatry. How do we test them? In this third and final episode in this special series, Adam Hunt presents a way to standardise evolutionary hypothesis testing to make it more rigorous, reliable and systematic.The article is available, open access, here: https://onlinelibrary.wiley.com/doi/epdf/10.1111/brv.70010A summary blog post can be found here: https://www.adamhunt.info/post/the-dcide-framework-published-in-biological-reviewsDr Adam Hunt is a researcher in the emerging field of evolutionary psychiatry at the Leverhulme Center for Human Evolutionary Studies at the University of Cambridge. Since 2019 he has served on the executive committee of the Evolutionary Psychiatry Special Interest Group of the Royal College of Psychiatrists.

Trying to explain disorders as functional is tempting, but often misses a critical point: sometimes it is not the disorder itself which is functional, but it is occurring as a by-product of a different adaptive system. In this second part of this special three part series, Adam Hunt explains this common confusion and the steps we can take to solve it.The article which this episode is based on is available, open access, here: https://onlinelibrary.wiley.com/doi/epdf/10.1111/brv.70010A summary blog post can be found here: https://www.adamhunt.info/post/the-dcide-framework-published-in-biological-reviewsDr Adam Hunt is a researcher in the emerging field of evolutionary psychiatry at the Leverhulme Center for Human Evolutionary Studies at the University of Cambridge.

Evolution has already happened, and we don't have a time machine: how can we test hypotheses about that process? This is a criticism raised since Darwin's time. In this special three part series, Adam Hunt presents his article which aims to make progress on this scientific methodology by providing an improved framework for evolutionary inference. This episode kicks off by giving the history of the problem.The article which this episode is based on is available, open access, here: https://onlinelibrary.wiley.com/doi/epdf/10.1111/brv.70010A summary blog post can be found here: https://www.adamhunt.info/post/the-dcide-framework-published-in-biological-reviewsDr Adam Hunt is a researcher in the emerging field of evolutionary psychiatry at the Leverhulme Center for Human Evolutionary Studies at the University of Cambridge.

Social media is bad for mental health right? Well... it's more complicated than that. In this episode, we discuss the ways in which novel digital technologies can also improve mental health, and how an evolutionary perspective on tech helps illuminate its dual effects of harming and healing.Tanay Katiyar is a PhD student, co-supervised by Amy Orben and Nikhil Chaudhary, at the MRC Cognition and Brain Sciences Unit (CBU) and the Leverhulme Centre for Human Evolutionary Studies at the University of Cambridge. Drawing on frameworks from cognitive science, evolutionary psychiatry and anthropology, he is currently investigating how our contemporary living conditions and digital environments both protect from and leave us vulnerable to mental health problems in novel ways. He studied economics as an undergraduate in India, and then did his masters in cognitive science at the ecole normale superieure in Paris. He is also a host of the Cognitations podcast, which is dedicated to cognitive science and interviews many renowned scholars across the psychological sciences.This podcast is financially supported by the Human Ecology Group of the Institute of Evolutionary Medicine at the University of Zurich.

Did mental disorders evolve to provide benefits to the community around us? Well, maybe, but these sorts of explanations could be criticised as naive 'group selection'. In this episode Adam goes into the nuance of understanding how evolution actually works in this common area of debate.Dr Adam Hunt is a researcher in the emerging field of evolutionary psychiatry at the Leverhulme Center for Human Evolutionary Studies at the University of Cambridge.

Why did the human species evolve autism? What about different forms of autism? How does an evolutionary perspective align with the neurodiversity movement?

Why do autism and schizophrenia exist? What are 'fast and slow' life history strategies? What are controversies and opportunities facing the field of evolutionary psychiatry? In this episode, we go deep with Marco Del Giudice... Dr. Marco Del Giudice is an Associate Professor in the Department of Life Sciences at the University of Trieste, Italy. His interdisciplinary research sits at the crossroads of human behavior, evolution, and development, and has led to integrative models such as the Adaptive Calibration Model (ACM) of stress responsivity, an evolutionary-developmental model of sex differences in attachment, and a unifying life history framework for evolutionary psychopathology. His work spans personality, motivation, attachment styles, developmental plasticity, and more recently, evolutionary immunology. Awarded the 2016 Early Career Award by the Human Behavior and Evolution Society, Dr. Del Giudice Is well known for pushing boundaries in understanding how evolution shapes our minds and behaviors, and his work in evolutionary psychiatry is well known, particularly for his book ‘Evolutionary Psychopathology’.

Humans rely on each other. Mothers, in particular, need help raising children. In this episode we discuss Professor Alessandra Cassar's work seeking to understand how maternal depression relates to gaining social support. We also touch on where evolutionary perspectives may be useful in structuring society more widely. Alessandra Cassar is a professor of economics at the University of San Francisco. Through laboratory and field experiments across the world, her studies focus on the contributions of evolutionary processes to shaping human behavior. Her current research concentrates on the under-studied areas of female competitiveness; the consequences of conflict and disaster victimization for altruism, trust, religiosity, risk, and time preferences; and the role of social networks for economic outcomes.

Why have humans evolved tendencies for substance addiction? In this episode, Adam and Tom discuss the evolutionary explanations for these vulnerabilities. The discussion is based on their paper "Evolutionary perspectives on substance and behavioural addictions: Distinct and shared pathways to understanding, prediction and prevention". Dr Tom Carpenter is a resident doctor in Psychiatry based in NHS Greater Glasgow & Clyde and an Honorary Clinical Lecturer at the University of Glasgow. He is also a member of the executive committee of the Evolutionary Psychiatry Special Interest Group of the Royal College of Psychiatrists. He studied medicine at the University of Edinburgh after initially studying Human Sciences at the University of Oxford, completing a Master’s degree in research in Animal Behaviour at Newcastle University, and having a brief career in marketing. He has worked in a specialist addictions service in Glasgow and currently works in an early intervention in psychosis service. He has current research and engagement projects around the usefulness and impact of evolutionary psychoeducation for mental health clinicians.

Social media, video games, gambling... why are some activities so rewarding that we become addicted? In this episode, we discuss the reason humans are susceptible to 'behavioural addictions', referencing our shared paper 'Evolutionary perspectives on substance and behavioural addictions: Distinct and shared pathways to understanding, prediction and prevention'. Dr. Giuseppe Pierpaolo Merola is an Italian psychiatrist and researcher currently practicing at San Donato Arezzo Hospital and serving as a Visiting Researcher at King's College London. His work focuses on genetics and evolutionary psychiatry. He is the author of the popular science book "Il paradosso della schizofrenia" and multiple scientific papers.
