What do the genetics of tail length and the genetics of semen quality have in common? Not much, except that our guest, Marnie Hodge, Sheep Genetics Senior Development Officer, has researched them both.Tail length is moderately to highly heritable, but in her research, Marnie found that measuring tail length in centimetres versus a scored system gives you far more accuracy and picks up significantly more genetic variation, which means faster rates of genetic gain if you're selecting for it.But what's actually changing when tails get shorter? Are we dropping vertebrae or just shortening bones? And what about correlations with body structure? Marnie explains what we know, what we don't, and why we don't have a tail length breeding value quite yet. On the opposite end of the scale, as with all reproduction traits, semen quality is lowly heritable. Marnie's research, "Heritability and Genetic Parameters for Semen Traits in Australian Sheep", showed that most of the variation in AI success wasn't down to motility, but more down to the variation in ewe management on each farm. So what does that mean for the establishment of a potential future breeding value? Marnie explains on the podcast. Plus Marnie gives us some updates on what's coming from Sheep Genetics and the combined analysis.Head Shepherd is brought to you by neXtgen Agri International Limited.

This episode was recorded in Reno, Nevada, during the 2025 Western Dairy Management Conference.Dr. Hutjens' presentation focused on herds producing seven pounds of milk fat and milk protein per cow per day, and the genetics, on-farm management and nutrition to make that happen. The panel discusses where components could top out, how added dietary fat has influenced components and the importance of high quality forage to de novo fat synthesis. (4:09)The panel explores how well nutritionists are keeping up with rapid genetic change in milk component production and how farmers respond to recommendations for things like rumen-protected fatty acids and supplemental fat. Dr. Nelson shares some of the unique challenges and opportunities faced by the California dairy producers he works with. (11:56)Dr. Hutjens gives some benchmark values for energy and protein efficiency. The panel debates the merit of energy-corrected milk per stall as an efficiency measure, with the consensus being it might lead to crowding, which would then probably decrease milk and component production due to decreasing cow comfort. The group also discusses selecting for feed efficiency and the heritability of feed efficiency. (16:33)The panel dives into the topic of feed ingredients. High-oleic soybeans and high quality forages are a focus in some parts of the country. Dr. Nelson discusses non-forage fiber sources available in the California market, such as citrus, plums, apples and carrots. The group talks more about how high-sugar byproducts influence rumen fermentation, which is different from starch, as well as benefits in palatability, digestibility and intake. (21:03)Dr. Hutjens talks about benchmarks for milk components and different strategies for increasing component production. Rumen-protected amino acids, purchased fats, roasted high-oleic soybeans and urea are discussed. The group also talks about what might happen if milk processors start asking for less milk fat, for example. Dr. Hutjens talks about how nutritionists can help balance rations to yield different results for different markets. (33:04)Panelists share their take-home thoughts.

The Story So Far The mid-20th century was the golden age of nurture. Psychoanalysis, behaviorism, and the spirit of the ‘60s convinced most experts that parents, peers, and propaganda were the most important causes of adult personality. Starting in the 1970s, the pendulum swung the other way. Twin studies shocked the world by demonstrating that most behavioral traits - especially socially relevant traits like IQ - were substantially genetic. Typical estimates for adult IQ found it was about 60% genetic, 40% unpredictable, and barely related at all to parenting or family environment. By the early 2000s, genetic science reached a point where scientists could start pinpointing the particular genes behind any given trait. Early candidate gene studies, which hoped to find single genes with substantial contributions to IQ, depression, or crime, mostly failed. They were replaced with genome wide association studies, which accepted that most interesting traits were polygenic - controlled by hundreds or thousands of genes - and trawled the whole genome searching for variants that might explain 0.1% or even 0.01% of the pie. The goal shifted toward polygenic scores - algorithms that accepted thousands of genes as input and spit out predictions of IQ, heart disease risk, or some other outcome of interest. The failed candidate gene studies had sample sizes in the three or four digits. The new genome-wide studies needed five or six digits to even get started. It was prohibitively difficult for individual studies to gather so many subjects, genotype them, and test them for the outcome of interest, so work shifted to big centralized genome repositories - most of all the UK Biobank - and easy-to-measure traits. Among the easiest of all was educational attainment (EA), ie how far someone had gotten in school. Were they a high school dropout? A PhD? Somewhere in between? This correlated with all the spicy outcomes of interest people wanted to debate - IQ, wealth, social class - while being objective and easy to ask about on a survey. Twin studies suggested that IQ was about 60% genetic, and EA about 40%. This seemed to make sense at the time - how far someone gets in school depends partly on their intelligence, but partly on fuzzier social factors like class / culture / parenting. The first genome-wide studies and polygenic scores found enough genes to explain 2%pp1 of this 40% pie. The remaining 38%, which twin studies deemed genetic but where researchers couldn't find the genes - became known as “the missing heritability” or “the heritability gap”. Scientists came up with two hypothesis for the gap, which have been dueling ever since: Maybe twin studies are wrong. Maybe there are genes we haven't found yet For most of the 2010s, hypothesis 2 looked pretty good. Researchers gradually gathered bigger and bigger sample sizes, and found more and more of the missing heritability. A big 2018 study increased the predictive power of known genes from 2% to 10%. An even bigger 2022 study increased it to 14%, and current state of the art is around 17%. Seems like it was sample size after all! Once the samples get big enough we'll reach 40% and finally close the gap, right? This post is the story of how that didn't happen, of the people trying to rehabilitate the twin-studies-are-wrong hypothesis, and of the current status of the debate. Its most important influence/foil is Sasha Gusev, whose blog The Infintesimal introduced me to the new anti-hereditarian movement and got me to research it further, but it's also inspired by Eric Turkheimer, Alex Young (not himself an anti-hereditarian, but his research helped ignite interest in this area), and Awais Aftab. (while I was working on this draft, the East Hunter Substack wrote a similar post. Theirs is good and I recommend it, but I think this one adds enough that I'm publishing anyway) https://www.astralcodexten.com/p/missing-heritability-much-more-than

Dr. Richard Haier is an emeritus professor of Pediatric Neurology at UC Irvine, who spent his career studying the neuroscience of intelligence. Over the course of his career, Haier has come to believe in the existence of a “g-factor,” a measurable quantity of broad spectrum intelligence that is universally predictive of success in all cultures. He also believes that intelligence is a fixed characteristic, and that it's possible to predict someone's intelligence by watching how their brain works when trying to solve a puzzle. We sit down with him to figure out how far one can take this theory of intelligence before running headlong into a heartless social darwinism, why intelligence research feels so creepy, if IQ tests are actually measuring what we think they're measuring, if intelligence is really the thing that we should be optimizing for, and if it's possible for technology to make us dumber.

IQ is, to say the least, a fraught concept. Psychologists have studied IQ—or g for “general cognitive ability”—maybe more than any other psychological construct. And they've learned some interesting things about it. That it's remarkably stable over the lifespan. That it really is general: people who ace one test of intellectual ability tend to ace others. And that IQs have risen markedly over the last century. At the same time, IQ seems to be met with increasing squeamishness, if not outright disdain, in many circles. It's often seen as crude, misguided, reductive—maybe a whole lot worse. There's no question, after all, that IQ has been misused—that it still gets misused—for all kinds of racist, classist, colonialist purposes. As if this wasn't all thorny enough, the study of IQ is also intimately bound up with the study of genetics. It's right there in the roiling center of debates about how genes and environment make us who we are. So, yeah, what to make of all this? How should we be thinking about IQ? My guest today is Dr. Eric Turkheimer. Eric is Professor of Psychology at the University of Virginia. He has studied intelligence and many other complex human traits for decades, and he's a major figure in the field of “behavior genetics.” Eric also has a new book out this fall—which I highly recommend—titled Understanding the Nature-Nurture Debate. In a field that has sometimes been accused of rampant optimism, Eric is—as you'll hear—a bit more measured. In this conversation, Eric and I focus on intelligence and its putatively genetic basis. We talk about why Eric doubts that we are anywhere close to an account of the biology of IQ. We discuss what makes intelligence such a formidable construct in psychology and why essentialist understandings of it are so intuitive. We talk about Francis Galton and the long shadow he's cast on the study of human behavior. We discuss the classic era of Twin Studies—an era in which researchers started to derive quantitative estimates of the heritability of complex traits. We talk about how the main takeaway from that era was that genes are quite important indeed, and about how more genetic techniques suggest that takeaway may have been a bit simplistic. Along the way, Eric and I touch on spelling ability, child prodigies, the chemical composition of money, the shared quirks of twins reared apart, the Flynn Effect, the Reverse Flynn Effect, birth order, the genetics of height, the problem of missing heritability, whether we should still be using IQ scores, and the role of behavior genetics in the broader social sciences.  Alright folks, lots in here—let's just get to it. On to my conversation with Dr. Eric Turkheimer. Enjoy!   A transcript of this episode will be available soon.   Notes and links 3:30 – The 1994 book The Bell Curve, by Richard Herrnstein a Charles Murray, dealt largely with the putative social implications of IQ research. It was extremely controversial and widely discussed.

See here for an attempt to test the claims of the “multiple intelligences” framework using some of the methods of traditional IQ research. For work on EQ (or Emotional Intelligence) see here. 19:00 – Dr. Turkheimer has also laid out his spelling test analogy in a Substack post. 22:30 – Dr. Turkheimer's 1998 paper, “Heritability and Biological Explanation.” 24:30 – For an in-passing treatment of the processing efficiency idea, see p. 195 of Daniel Nettle's book Personality. See also Richard Haier's book, The Neuroscience of Intelligence. 26:00 – The original study on the relationship between pupil size and intelligence. A more recent study that fails to replicate those findings. 31:00 – For an argument that child prodigies constitute an argument for “nature,” see here. For a memorable narrative account of one child prodigy, see here. 32:00 – A meta-analysis of the Flynn effect. We have previously discussed the Flynn Effect in an episode with Michael Muthukrishna. 37:00 – James Flynn's book, What is Intelligence? On the reversal of the Flynn Effect, see here. 40:00 – The phrase “nature-nurture” originally comes from Shakespeare and was picked up by Francis Galton. In The Tempest, Prospero describes Caliban as “a born devil on whose nature/ Nurture can never stick.” 41:00 – For a biography of Galton, see here. For an article-length account of Galton's role in the birth of eugenics, see here. 50:00 – For an account of R.A. Fisher's 1918 paper and its continuing influence, see here. 55:00 – See Dr. Turkheimer's paper on the “nonshared environment”—E in the ACE model. 57:00 – A study coming out of the Minnesota Study of Twins reared apart. A New York Times article recounting some of the interesting anecdata in the Minnesota Study. 1:00:00 – See Dr. Turkheimer's 2000 paper on the “three laws of behavior genetics.” Note that this is not, in fact, Dr. Turkheimer's most cited paper (though it is very well cited). 1:03:00 – For another view of the state of behavior genetics in the postgenomic era, see here. 1:11:00 – For Dr. Turkheimer's work on poverty, heritability, and IQ, see here. 1:13:00 – A recent large-scale analysis of birth order effects on personality. 1:16:00 – For Dr. Turkheimer's take on the missing heritability problem, see here and here.    1:19:00 – A recent study on the missing heritability problem in the case of height. 1:30:00 – On the dark side of IQ, see Chapter 9 of Dr. Turkheimer's book.

Dr. Stephen Storage, a child psychiatrist, discusses the key stages of child psychological development and the impact of family dynamics and early childhood experiences on a child's mental health. He explains that there are four stages of development: infancy (0-2 years), early childhood (2-6 years), middle childhood (6-12 years), and adolescence (12-18 years). Each stage has a developmental task that the child must master, and if they don't, it can lead to issues later in life. Factors such as attachment, trauma, and adverse childhood experiences can shape a child's psyche and impact their relationships and mental health as adults. Trauma shapes the biology of the developing brain, leading to changes in brain activity and blood flow. The impact of trauma on the brain can be addressed through various therapies, supplements, and lifestyle changes. Genetics play a significant role in mental health conditions, with conditions like ADHD and autism having a high heritability. The three pillars of brain health are sleep, exercise, and nutrition. Social media can have negative effects on the developing brain, leading to higher rates of anxiety, depression, and ADHD. However, social media can also be a platform for connection and spreading awareness about mental health. It is important to set limits on social media use and ensure that the content is interactive and educational. Play is crucial for the psychological development of children, promoting problem-solving, creativity, social skills, emotional regulation, and confidence. Parents should be aware of the signs of mental health struggles in their children and foster open communication.Amen Clinic@drstevenstorage@therunningwinemom_

Listen to ASCO's Journal of Clinical Oncology essay, “The Heritability of Cancer” by Dr. Leeat Granek, Associate Professor at York University in Toronto, Canada. The essay is followed by an interview with Granek and host Dr. Lidia Schapira. Granek shares how her mother's diagnose with breast cancer continues to shape her own life and experiences. TRANSCRIPT Narrator: The Heritability of Cancer, by Leeat Granek  I was 9 years old when my mother was first diagnosed with breast cancer and 25 when she died. The boundary between before and after is so clear that it feels like I have lived two lives. I went from being a careless, cerebral, quirky child to a rough version of the responsible, reliable, and vigilant adult I would eventually became. With cancer came the fear of losing my mother, and with that fear came an unwelcome but necessary maturity. There were other important life events impacting our family around that time that contributed to this sense of split. We had just moved from Israel to Toronto and knew few people in our new environment. My mother had just given birth to my baby brother, and my parents had bought a new house for our growing family. At the time, I was starting third grade in a new school—the fifth new school since beginning kindergarten. All this in addition to the diagnosis. My mother was only 33 years old—the same age I am now. While I adapted to everything else—new house, new school, new brother, new country—cancer insisted on sticking around, and it claimed not only my mother's life but, in many ways, my own. Cancer enters the body of the caregivers in ways that move far beyond the domestic work involved in the running of the house or the management of medications and appointments. It can become part of caregiver DNA through inherited genes, but it often does so in more insidious ways. My mother lived with the disease for 17 years before she died in 2005. It is fair to say I grew up in the hospital. Over the years, there were multiple surgeries, along with episodes of weekly chemotherapy and daily radiation sessions. She suffered a host of complications that came with metastatic disease and its treatment, including four instances of strep A bacteremia. Many major events happened in the hospital. We ate Chinese food with our matzos on Passover in her room and lit Hanukkah candles in the waiting room where we accidentally set off the fire alarm on the seventh night, to the consternation of the nursing staff. My 11th, 15th, 18th, and 25th birthdays were celebrated in cramped hospital quarters, cutting the birthday cake with a dull plastic knife. Indeed, the last birthday we had together was my 25th, and we marked it in the hospital 2 days before she died. In her last lucid moment, she managed to miraculously lift out of the fog caused by brain metastases to give me a kiss and exclaim “Mazal tov, Leeatie!” I remember the sounds and the smells. Static codes being called out over the hospital loudspeakers. The haunting “clink, clink, clink” of the staples being removed from my mother's skin graft and landing with a loud clatter in a silver bowl. The pale green hallways and their antiseptic smell, which I grew to hate. The airless temperature that was neither hot nor cold—hospital weather, I used to call it. The hospital, with its sounds and smells, was my second home. It sounds awful. And it was a lot of the time, but there were many good moments as well. My mother was smart, intuitive, funny, and astonishingly optimistic. She was always laughing and incredibly giving with her love and affection. We were exceptionally close. Her eyes lit up and her arms stretched out to give me a hug every single time I walked into her room. She would say things like, “Leeatie, I love you so much. I wouldn't change a single thing about you! How did I get to be so lucky to have a daughter like you?” and “There's no one in the world I would rather spend time with than you.” I didn't have to do anything to earn her affection. I felt that I always came first, that I was always wanted and loved, and that my mother was always entirely there for me in every sense of the word. The hospital days that punctuated much of my childhood, adolescence, and young adulthood were both an annoyance and a blessing. There was nothing else to do but simply be together, which was fun and easy, thankfully. When I was older and no longer living at home, I would sometimes sleep over in her hospital room during her admissions. We would curl up in the twin bed and talk for hours until we both fell asleep, or we would sit together, each absorbed in her own book, comforted by the warmness of being together.  When I think about being a caregiver for my mom, and by extension a caregiver for our family, it was not the hours of care work—the babysitting, driving to appointments, spending time in the hospital—that consumed me. The impact was long-lasting and continues to this day. As a health psychologist and a researcher in the area of psychooncology, I know the permanent and long-term devastations cancer causes throughout the caregiver's—in my case, the daughter's—entire life span. To this day, I have no real sense of what normal physical development for a woman should feel and look like, and in some sense, I never will. I entered puberty around the same time my mother was having her breasts and ovaries removed, which made that phase frightening and emotionally difficult. And now, I have no mother to turn to and ask about my endlessly evolving female form, no mother to guide me through future pregnancies or talk me through gray hair and menopause.  Cancer shaped my young adulthood and my emotional development. At 20 years old, I was dealing with issues facing 60-year-olds who care for ill and aging parents. Because part of me recognized that time was running out—indeed, because I lived almost my entire life with a neon awareness of my mother's mortality—I was tethered to home and making decisions about school, life, and love that would keep me close to her. I don't regret these choices or a single moment that I chose to spend with her, and now I have an entire lifetime to come and go as I please. Being challenged with a cancer-driven perspective at 20, however, carries risks of having an entire lifetime being developmentally out of step with one's peers and unprepared for life events outside a hospital. For example, at 25, I could look death in the face without trembling and without abandoning my mother at her end, but I was unprepared to face the dating world that most young adults would have no trouble navigating. Although I was and remain a loved, nurtured, and supported daughter, cancer diverted the vast majority of the temporal, emotional, financial, and physical resources in our family toward fighting the disease. When she was alive, my mother was fully present in my life. But even her unconditional love could not repair the reality of my out-of-sync development as a child and young adult or today make up for her continued absence in my life. My absent mother is at the core of a black hole of grief that remains inside of me and that has been painfully pried open with subsequent losses to cancer—my grandmother and my aunt, a professor I admired and family friend that I loved. Each loss re-exposes a haunting grief I have learned to accept and live with. Grief is a shadow that looms large in my life. It is both the topic I chose to study and the affect I advocate fiercely for,1–4 because as I have learned through my own experiences and research, love and light come from the same place as grief and darkness.  The ability to grieve our losses fully also allows us to love and appreciate the people in our lives when they are still with us. And then, of course, there is the worry: the biannual check-ups, magnetic resonance imaging scans, and mammograms; the surveillance and the false positives and the constant paradoxical tension that comes with the awareness of the nature of these tests provide a false sense of control over a disease that refuses to be harnessed.  The literature about the impact of parental cancer on children at the time of diagnosis, during treatment, after surgery, and even at the time of death is extensive,5–6 but few of these studies acknowledge how much this disease alters the life course of the child well after the parent has recovered or has died. Being a caregiver for a patient with cancer consumed much of my childhood, adolescence, and young adulthood when my mother was alive and charted the course for my future as a health psychologist working in the field of psychooncology. Although many years have passed and although I have a doctorate in hand, several years of postdoctoral training in the field of psychooncology, an academic career studying these issues, and dozens of publications from my research on the psychological and emotional effects of cancer on patients, caregivers, and their families,7–16 from time to time, I still feel like a scared 9-year-old child trying to gain control over this disease and get out of the shadow that cancer has cast on my life. Dr. Lidia Schapira: Hello, and welcome to JCO's Cancer Stories, the Art of Oncology, which features essays and personal reflections from authors exploring their experience in the field of oncology. I'm your host, Dr. Lidia Schapira. I'm a Professor of Medicine at Stanford University. Today we are joined by Dr. Leeat Granek, Associate Professor at York University in Toronto, Canada, in the School of Social Policy and Health Management. In this episode, we will be talking about her Art of Oncology article, "The Heritability of Cancer." At the time of this recording, our guest has no disclosures. Leeat, welcome to our podcast and thank you for joining us. Dr. Leeat Granek: Thank you so much for having me. It's a pleasure.  Dr. Lidia Schapira: Your essay is a classic, and I'm so glad that we were able to include it in the recent anthology of Art of Oncology. So let's start by talking a little bit about what led you to not only write, but decide to share this essay eight years after your mother passed of breast cancer. Bring us to that moment. Tell us what you were thinking.  Dr. Leeat Granek: Yeah, so that's a great question. And I recently, in preparation for this interview, reread it, and I was a little taken aback, even by how exposed and how vulnerable it was. But I really like that essay, and I'm really glad that it was published. It was kind of a culmination of a lot of thoughts that I was having as a person who has researched grief for many years, and as a person who was working in the field of psycho oncology, doing research in the area, and as a grieving daughter. And I think eight years is nothing in the grieving trajectory, right? We often think about grief as something acute that happens to you, and then you get over it and you move on with your life, and that certainly has not been my experience of grieving. I think it changes as you change, and it's just a constant presence in your life. And I was thinking about that in the context of being a caregiver for somebody who has cancer. So I think my experience is a little different than others, just because my mom was very young. She was 33 when she was diagnosed, and I was only nine. And she lived with this metastatic disease for nearly 20 years. So we had a very long journey with cancer. And I can kind of see now, as I reread it, the parallel thinking processes I had about grief and about cancer. And being a researcher in the field, I still feel that there are a lot of gaps in terms of the caregiver experience. But this idea of heritability, we often think about cancer as something you inherit genetically through our genetic makeup. But I think that it really, especially when you're young, changes your whole life trajectory. And I could not find anything in the literature that spoke about it in that very longitudinal kind of way and the way the impact of cancer changes you throughout your entire life. And so it just came from a very personal place, but also that intersection of being aware of the different literatures and how they came together.  Dr. Lidia Schapira: Let's unpack this a little bit. One of the things that you just said was that you shared your vulnerabilities, and I want to ask you a little bit more about that. Here you are. You're about the same age that when your mother was living with this as a young woman. I think you said that she was diagnosed roughly at the time that you were writing this. And you decide to explore this wearing a little bit of your research hat in a very deeply personal way. But then the question I wanted to ask you is your decision to share this with the community of oncologists, the people you knew very well because they had looked after your mother for all those years. Tell me a little bit about that. How did you make the decision not only to write it, but to share it? Dr. Leeat Granek: That's a great question. This also pertains to the research that I do, because a lot of the research I was doing at the time, as a result of my experiences with cancer teams as a child, looked at the emotional impact of being an oncologist. I did a series of studies looking at the way oncologists grieve and how they feel when patients die, some of the emotional burdens of the work. And they were very vulnerable in sharing their experiences. And so I thought, well, they're telling me about their experiences, I can also tell them about mine. And I think that there's kind of a mythology around oncologists. I'm doing studies now on surgeons as well, and I think there's the same mythology around surgeons is that they don't feel or everything is compartmentalized and everything's separate.  But from my research, I knew that that wasn't the case. And I felt that, although oncologists and oncology teams and nurses as well, witness patient suffering and family suffering, that there was nothing in the literature that kind of brought it home in this very visceral way. I don't think it would have been a surprise for any oncologist reading it, because when you follow families or when you follow parents, you see the children coming in. And so there was something about this intersection of their vulnerability and my vulnerability, enriching the experience of what it means to be a patient, and what does it mean to be a healthcare provider, which is not something that's often discussed in medicine at all. Dr. Lidia Schapira: So to your point, I think that telling the story was a beautiful sort of vehicle for opening up the topic. You were doing it through your research. But telling a story can often start a conversation in a very different way. That's what we try to do also in selecting these essays for Art of Oncology, to bring a story that's deeply personal, that reflects one's lived experience, but opens up a topic that is otherwise perhaps not talked about as much as we think it should. So let me go back and ask, what was the impact of telling the story on your research?  Dr. Leeat Granek: I just want to add something about what you just said about stories. The very first paper that I published on oncologist experiences of grief, I wrote an op-ed for the New York Times about that research. And it was very story-based. It was very much telling a story, and I was telling my own story as well as a story about the research. And the response to that op-ed was so profound and so much more powerful than any paper I had ever published. I got thousands of emails from people around the world, oncologists and healthcare providers around the world, just saying how touched and how moved they were by that op-ed. And that is the power of the story that you're talking about right now, that we're vying for these peer-reviewed articles all the time. But actually, the impact of just telling a story is so much more meaningful and visceral for the reader than just outlining the research findings. Dr. Lidia Schapira: And it sounds like just receiving all of those emails after your op-ed was probably very validating. We can get rejected when we apply for grants, but people were telling you what you're onto is really significant.   Dr. Leeat Granek: Yeah. And I think that validating in the sense that what I felt was that as you, exactly the words you just used, that it was a conversation that was not being had to the detriment of all. And so it validated that feeling of, yeah, this is something that's really important for us to be talking about in oncology. And just in terms of the response to "The Heritability of Cancer," it was a long time ago. This is 2014, so 10 years ago. I don't remember entirely what are the specific things that people said, but I do remember getting a lot of emails about it, mostly from healthcare providers, so less from caregivers or patients who may not have subscriptions to JCO, but maybe through the podcast now will have more access. Just saying this really shed some light as to the experience of what does it mean for the extended family that I think is not often considered. Certainly, we don't think about kids very often when a parent is going through cancer. Dr. Lidia Schapira: If you were to write this today, what would you do differently? Dr. Leeat Granek: I think what's changed for me– I don't think I would do anything differently, but what I think has changed is that I've had a child since I written that. Having a seven-year-old and thinking about what it's like to be going through a cancer diagnosis or cancer treatment while you have children. That piece was very centered on me and my experiences, and now I have even another layer of empathy and compassion for my mom, who had a newborn at the time. And I can just not imagine anything more– it's going to make me cry just even now just by thinking about it - it's just scary to have such a life-threatening diagnosis when you're a parent. Just like grief, like I said earlier, being a victim of cancer or being part of your family, that impact is lifelong and it changes as your development changes. Now as a parent, my grief is different than it was before I became a parent. And now as a parent, my understanding of what my mother was going through is changed. That terror and fear is so overwhelming. Dr. Lidia Schapira: So, Leeat, I can't help myself, but I need to ask you some practical questions. You're a psycho-oncologist, an expert in grief, and you've talked to and interviewed hundreds of oncologists who have shared stories, you're now a parent, you've lived through it. What it makes me think is that when we think about grief counseling or support for grieving children or bereaved spouses or parents, you think about it as an acute intervention and what you're suggesting is this needs to be explored throughout the life cycle. What are your thoughts about that and what should we be thinking about? Dr. Leeat Granek: I've written a lot about this in my grief work. The evidence for psychological counseling for grief is not strong actually when we look at the literature. For acute grief experiences in the immediate aftermath, sometimes it's helpful having someone to talk to. But in actuality, the most helpful is having a community in which grief is an open, accepted, acknowledged, part of living life. And that does not change after the first month or the first six months or the year, five years or ten years.   Other people may have moved on very quickly, but you're left with the impact of that loss. And I think the impact of that loss is not only after, when the person has died, it's also that progressive loss of function. The kind of witnessing of your loved one deteriorating. It's not just meals that you need, you also need that emotional support. And that emotional support doesn't necessarily have to take the form of, “Tell me about your grieving right now.” Sometimes it's just being with. And I think that certainly in North America, we're not very good at integrating grief, loss, pain, suffering, and negative emotions into our day to day lives. So partly, 10 years, 20 years, or 25 years later, it's hard for people to remember that loss.  So I think the person is grieving that many years after may have to reach out and ask for the support. But I think it's done really well in certain religions. I am Jewish and in the Jewish background, you have so many layers of mourning that's lifelong. So you have the acute grieving experience where it's seven days or 30 days or one year. And then every year progressively after that four times a year, you say a blessing and remembrance and give charity in the name of the dead. And for religious people, I'm not religious, this idea of every single day for that first year having to go synagogue and having to have at least nine other people that could be there with you to say the prayer for the dead, whether you believe or not believe, whether you're religious or not, I think the brilliance in those kinds of rituals is that it simply brings you together with other people who see you everyday.  And decades later, still that four times a year that you're meeting with people and you're saying a prayer, or that yearly yahrzeit, that memorial allows people a very very defined space in which to support the mourner. And I think other religions have it too.    Dr. Lidia Schapira: Those are beautiful thoughts, and I think it speaks to connection and community as a way of supporting rather than pathologizing the grief and thinking what one needs is some sort of a professional intervention. I can't help but add that as a community of caring oncologists, we are constantly grieving. We are immersed in grief, and in part, there is no label for how we feel. There is a small literature that you probably know far better than I do on disenfranchised grief, which is the idea that we can't quite claim to grieve because we weren't a relative or best friend, but we deeply cared and we lost and we grieve. So I find that this conversation is so helpful because I think what we're doing is we're talking about what we ought to be talking about more: perhaps acknowledging more from a point of view, as you say, of a parent, researcher, caregiver, medical or healthcare professional who's involved. We are living in a society where perhaps we are afraid to think that grief is a part of our life, and we can be happy even if we grieve. Dr. Leeat Granek: Yeah.  Dr. Lidia Schapira: Happiness is not just the absence of sadness, I think, I don't know. You are the psycho-oncologist, tell me if I'm wrong. Dr. Leeat Granek: I so appreciate what you're saying and it makes me sad to hear that grief is still so stigmatized among oncologists. I think what my research has found and all my conversations with people over the decades now is, of course, oncologists feel a lot of things. Not just grief but pain and suffering, distress at seeing their patients and their families suffering and declining. Why wouldn't they? They are human beings. So I think this idea that people don't feel or don't have space to feel is part of what leads to burn out actually. I think there's a kind of fear that grief and the pain and suffering is the burn out but it's not. In fact, what's the burn out is the inability to talk about or to have a space to discuss it. And I also think that the thing that gives meaning to the work is that relationship with patients.  And by the way, I'm finding that with the surgeons as well. The surgeons are even more kind of disconnected in terms of emotions. We kind of assume that they feel nothing, that they are so disconnected. By the way, I just have to say, the surgeons say, “I can't believe the oncologists does that job.” They find it really hard to believe that oncologists can do that, that they can never do that job. And the oncologists say that about the surgeons, too. So I think it's very interesting how different medical groups look at each other.  But there's this kind of sense that's very unique about the grieving experience of how care providers is and they feel a lot of guilt and a lot of self doubt, and self criticism when patients die even though they know consciously that there's nothing that they could've done and that is just the disease that is taking over. That lack of control and that sense of having failed the patient is so strong. That is a very unique grieving experience for providers who feel responsible for the care of their patients. The fact that there is no training or no education or no space to talk about that is just appalling to me as a psychologist. Because I just think you learn how to do everything else. There's so much training on communicating bad news, on dealing with patient anger, on dealing with patient emotions and how to respond. But nothing on how to deal with your own emotions in response to this. For years, it's just about communications training.  One of the things we find in the literature is that even when you provide communication training to oncologists that have to discuss end of life, often those skills are not sufficient to be able to have that conversation. And what's missing is the notion that I found in my own research that they don't have this conversation because they feel so uncomfortable with it themselves. And so until they have some self reflective practice for healthcare providers, all the skills training in the world is not going to help because it's about your own emotional resistance.  Dr. Lidia Schapira: Well, this has been a phenomenal conversation, and I hope people will look at some of the beautiful research you've done in this field.

It's Fair To Describe Schizophrenia As Probably Mostly Genetic

Slate Star Codex Podcast

Famous schizophrenia researcher E. Fuller Torrey recently wrote a paper trying to cast doubt on whether schizophrenia is really genetic. His exact argument is complicated, but I feel like it sort of equivocates between “the studies showing that schizophrenia are genetic are wrong” and “the studies are right, but in a philosophical sense we shouldn't describe it as ‘mostly genetic'”. Awais Aftab makes a clearer version of the philosophical argument. He's not especially interested in debating the studies. But he says that even if the studies are right and schizophrenia is 80% heritable, we shouldn't call it a genetic disease. He says: Heritability is “biologically vacuous” (Matthews & Turkheimer, 2022), and I think we would be better off if more of us hesitated to assert that schizophrenia is a “genetic disorder” based predominantly on heritability estimates. I think about questions like these through the lens of avoiding isolated demands for rigor. There are always complicated ways that any statement is false. So the question is never whether a statement is perfectly true in every sense. It's what happens when we treat it fairly, using the same normal criteria we use for everything else. https://www.astralcodexten.com/p/its-fair-to-describe-schizophrenia

Vidcast:  https://www.instagram.com/p/C3GaGppLUoW/ Two-thirds of your susceptibility to the CoVid virus is controlled by your genetic makeup while one-third is determined by environmental factors.   This the conclusion of a study by Columbia University biostatisticians following their study of 12, 764 patients with positive or negative CoVid PCR tests. Their data demonstrated that, at the onset of the CoVid pandemic in 2020, environmental factors appeared to correlate with both the incidence and the severity of CoVid infections in about 57% of cases.  Heritability only explained about 43% of cases. Such environmental factors include sick household members, community levels of disease, and measures taken to avoid disease spread including masking, social distancing, and quarantine.  By the end of 2021, heritability-genetic factors had become 1.5-times more important as environmental issues became less important with the advent of vaccine and infection-driven immunity. Having reported these relationships, the researchers do point out that little is known to date about the actual genetics of CoVid infectibility.  One gene link association that is documented is that of CoVid susceptibility and ABO blood groups.  Those having type 0 blood groups are nearly 30% less likely to develop infection while those having type A blood groups were more than 30% more likely to develop infections.   https://www.nature.com/articles/s41467-023-44250-7 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7834371/ #CoVid #genetics #environmental #vaccination #masking #distancing

Discussion of ADHD is EVERYWHERE in the news and social media. Often we hear patients, friends, and family members stating “I saw a post on FB/Instagram/Twitter/TikTok about ADHD that resonated with me, should I get tested?” While many people experience periods of inattention, unfocused motor activity, and impulsivity, those with ADHD experience these symptoms to a much greater degree, and these behaviors can often interfere with their social lives, working lives, and general mental health. Depending on your age and many other social factors, screening and evaluation for ADHD may have passed you over during your young, formative years.

We discuss individual differences between people — focusing on differences in how people sense the world around them and the roles that chance, heredity, and life experiences (even in utero) play in determining our physical and cognitive traits. We discuss the bidirectional connection between the mind and body and how our thoughts and mental practices (e.g., meditation and breathwork) impact our health. We also discuss the link between inflammation and depression. We also discuss Dr. Linden's terminal illness diagnosis, his mindset during chemotherapy and what his diagnosis has taught him about the mind, gratitude, time perception and life. This episode also covers sensual touch, cerebellar function, and epigenetic inheritance and ought to be of interest to all interested in neuroscience, genetics, psychology and human development.  For the full show notes, including articles, books, and other resources, visit hubermanlab.com.

Gavin Douglas and colleagues published a paper assessing microbiome research and assertions that the human microbiome explains missing heritability in nature. He discusses this issue and explains What are classic ways of understanding genetic variation in humans and how recently microbiome research has entered this understanding, What the holobiont model is and how it involves claims regarding the microbiome and missing heritability in nature, and How their paper views the microbiome as more of potential element in genetic variation in humans and necessitates more consideration regarding how to integrate it outside of the strict, holobiont model. Gavin Douglas is a PhD Candidate in the Langille Lab in the Deptartment of Microbiology and Immunology at Dalhousie University. His background is in human genetics and he has just published an intriguing paper called “Re-evaluating the relationship between missing heritability and the microbiome” in the journal Microbiome. He helps listeners understand the basics regarding the issue by explaining heritability as the proportion of variation in a phenotype in a given population explained by genetic variance. He offers more background to this standard and then explains the “case of the missing heritability,” which basically indicates the variation that isn't explained.  Several hypotheses have emerged to explain this missing heritability, several of which are tied to the human microbiome. He describes how, for example, a holobiont model of a human organism puts forward a hologenome—a combined genome that includes the microbiome and might capture the missing heritability. The article discusses this theory and points out ways it doesn't quite fit. For example, the holobiont doesn't present a combined evolutionary unit that transmits over generations. But he does think the microbiome plays a role in this mystery. He explains how and why and different ways scientists use these ideas.  For more, follow him on twitter as @gavin_m_douglas and read the open-access paper here: Re-evaluating the relationship between missing heritability and the microbiome.

Welcome to The Nonlinear Library, where we use Text-to-Speech software to convert the best writing from the Rationalist and EA communities into audio. This is: Heritability, Behaviorism, and Within-Lifetime RL, published by Steven Byrnes on February 2, 2023 on LessWrong. I'm a firm subscriber to both: (A) The theory that people's personalities are significantly predictable from their genes, and mostly independent of how their parents raised them (at least within the typical distribution, i.e. leaving aside cases of flagrant abuse and neglect etc.). See e.g. popular expositions of this theory by Judith Harris or by Bryan Caplan for the fine print. (B) The theory that we should think of people's beliefs and goals and preferences developing via within-lifetime learning, and more specifically via within-lifetime Model-based Reinforcement Learning (details), with randomly-initialized (“learning-from-scratch”) world-model and value function. I feel like there's an idea in the air that these two beliefs are contradictory. For example, one time someone politely informed me that (A) is true and therefore obviously (B) must be false. Needless to say, I don't think they're contradictory. Indeed, I think that (B) naturally implies (A). But I admit that they sorta feel contradictory. Why do they feel that way? I think because: (A) is sorta vaguely affiliated with cognitive science, evolutionary psychology, etc. (B) is sorta vaguely affiliated with B.F. Skinner-style behaviorism, .and those two schools-of-thought are generally considered to be bitter enemies. In this short post I want to explain why we should put aside that baggage and see (A) & (B) as natural allies. Two dubious steps to get from (B) to Behaviorism Here's the fleshed-out argument as I see it: I'll go through the two dubious steps in the opposite order. Dubious step #1: “No more learning / unlearning after the kid grows up” Here are two stories: “RL with continuous learning” story: The person has an internal reward function in their head, and over time they'll settle into the patterns of thought & behavior that best tickle their internal reward function. If they spend a lot of time in the presence of their parents, they'll gradually learn patterns of thought & behavior that best tickle their innate internal reward function in the presence of their parents. If they spend a lot of time hanging out with friends, they'll gradually learn patterns of thought & behavior that best tickle their innate internal reward function when they're hanging out with friends. As adults in society, they'll gradually learn patterns of thought & behavior that best tickle their innate internal reward function as adults in society. “RL learn-then-get-stuck” story: The kid learns patterns of thoughts & behavior in childhood, and then sticks with those patterns for the rest of their lives no matter what. Claim: I think the “RL with continuous learning” story, not the “RL learn-then-get-stuck” story, is how we should generally be thinking about things. At least in humans. (Probably also in non-human animals, but that's off-topic.) I am not making a strong statement that the “RL learn-then-get-stuck” story is obviously and universally wrong and stupid nonsense. Indeed, I think there are edge cases where the “learn-then-get-stuck” story is true. For example, childhood phobias can sometimes persist into adulthood, and certainly childhood regional accents do. Some related discussion is at Scott Alexander's blog post “Trapped priors”. Instead, I think we should mainly believe the “RL with continuous learning” story for empirical reasons: Heritability studies: See top. More specifically, note that (IIRC) parenting style can have some effect on what a kid believes and how they behave while a child, but these effects fade out when the kid grows up. Culture shifts: Culture shifts are in fact possible, contrary to the “RL learn-then-get-stuck” story. For example, almost everybody in the USA opposed gay marria...

EA - The heritability of human values: A behavior genetic critique of Shard Theory by Geoffrey Miller

Welcome to The Nonlinear Library, where we use Text-to-Speech software to convert the best writing from the Rationalist and EA communities into audio. This is: The heritability of human values: A behavior genetic critique of Shard Theory, published by Geoffrey Miller on October 20, 2022 on The Effective Altruism Forum. Overview (TL;DR): Shard Theory is a new approach to understanding the formation of human values, which aims to help solve the problem of how to align advanced AI systems with human values (the ‘AI alignment problem'). Shard Theory has provoked a lot of interest and discussion on LessWrong, AI Alignment Forum, and EA Forum in recent months. However, Shard Theory incorporates a relatively Blank Slate view about the origins of human values that is empirically inconsistent with many studies in behavior genetics indicating that many human values show heritable genetic variation across individuals. I'll focus in this essay on the empirical claims of Shard Theory, the behavior genetic evidence that challenges those claims, and the implications for developing more accurate models of human values for AI alignment. Introduction: Shard Theory as an falsifiable theory of human values The goal of the ‘AI alignment' field is to help future Artificial Intelligence systems become better aligned with human values. Thus, to achieve AI alignment, we might need a good theory of human values. A new approach called “Shard Theory” aims to develop such a theory of how humans develop values. My goal in this essay is to assess whether Shard Theory offers an empirically accurate model of human value formation, given what we know from behavior genetics about the heritability of human values. The stakes here are high. If Shard Theory becomes influential in guiding further alignment research, but if its model of human values is not accurate, then Shard Theory may not help improve AI safety. These kinds of empirical problems are not limited to Shard Theory. Many proposals that I've seen for AI ‘alignment with human values' seem to ignore most of the research on human values in the behavioral and social sciences. I've tried to challenge this empirical neglect of value research in four previous essays for EA Forum, on the heterogeneity of value types in humans individuals, the diversity of values across individuals, the importance of body/corporeal values, and the importance of religious values. Note that this essay is a rough draft of some preliminary thoughts, and I welcome any feedback, comments, criticisms, and elaborations. In future essays I plan to critique Shard Theory from the perspectives of several other fields, such as evolutionary biology, animal behavior research, behaviorist learning theory, and evolutionary psychology. Background on Shard Theory Shard Theory has been developed mostly by Quintin Pope (a computer science Ph.D. student at Oregon State University) and Alex Turner (a post-doctoral researcher at the Center for Human-Compatible AI at UC Berkeley). Over the last few months, they posted a series of essays about Shard Theory on LessWrong.com, including this main essay here , ‘The shard theory of human values' (dated Sept 3, 2022), plus auxiliary essays such as: ‘Human values & biases are not accessible to the genome' (July 7, 2022), ‘Humans provide an untapped wealth of evidence about alignment' (July 13, 2022), ‘Reward is not the optimizer' (July 24, 2022), and ‘Evolution is a bad analogy for AGI: Inner alignment' (Aug 13, 2022). [This is not a complete list of their Shard Theory writings; it's just the set that seems most relevant to the critiques I'll make in this essay.] Also, David Udell published this useful summary: ‘Shard Theory: An overview' (Aug 10, 2022). There's a lot to like about Shard Theory. It takes seriously the potentially catastrophic risks from AI. It understands that ‘AI alignment with human values' requires some fairly well-developed notions about where human values come from, what they're for, a...

Huberman Lab Podcast Notes Key Takeaways Manic episodes are the defining criteria of bipolar disorder AKA bipolar depression – not all people with bipolar disorder experience deep depressionTypes of bipolar disorder: (1) Bipolar I – characterized by an extended period of mania (elevated mood, impulse, distractibility, etc.) – the mania is extreme and noticeable to people around; (2) Bipolar II – characterized by swings of hypomania (lessened intensity of mania or shorter duration of mania) and depressive episodesBipolar I presents itself more overtly because of bouts of mania; Bipolar II can duck under the radar because of the intense depressive state and hypomania which might look more normal compared to a depressive stateHeritability of bipolar disorder among the general population is 85% – if someone has bipolar disorder, it's likely they inherited a gene, set of genes, or susceptibility in genes to influences that can trigger bipolar disorderMajor neurological deficits in people with bipolar disorder: (1) lack of internal awareness (interoception); (2) top-down control on overall levels of energy (reduction in connectivity between parietal region and limbic system)Treatment approaches need to be comprehensive and in combination – for example, lithium + talk therapy“It's naïve and in fact, wrong, to say that lifestyle interventions alone are going to prevent especially extreme forms of mania and depression.” – Dr. Andrew HubermanRead the full notes @ podcastnotes.orgIn this episode, I explain the biology, symptoms, causes and types of bipolar disorder (sometimes called bipolar depression). I discuss neuroplasticity and how the brain normally regulates mood, energy, and perceptions; then, I contrast that with the biology of bipolar disorder, which is characterized by extremes of energy and mood, e.g., mania and depression. I outline the mechanisms through which bipolar disorder manifests in the brain, including deficits of interoception and reduced connections between the parietal and limbic systems. I also outline how treatment options (such as lithium) work in part through homeostatic plasticity.' I discuss not only lithium but also the treatment of bipolar with ketamine, different talk therapies, electroconvulsive therapy, transcranial magnetic stimulation, and nutraceuticals, including Omega-3 and Inositol supplementation. This episode should interest anyone who has or knows someone with bipolar disorder and, more broadly, those interested in how the brain works to create a balance between thoughts, energy levels, focus, and mood.

I discuss not only lithium but also the treatment of bipolar with ketamine, different talk therapies, electroconvulsive therapy, transcranial magnetic stimulation, and nutraceuticals, including Omega-3 and Inositol supplementation. This episode should interest anyone who has or knows someone with bipolar disorder and, more broadly, those interested in how the brain works to create a balance between thoughts, energy levels, focus, and mood.

Selam fularsızlar. Zeka ve kalıtım konularını konuşmak zor, ama bir deneyelim bakalım. Bugün, zeka kalıtsallığına olan entelektüel direnci, başarı için öne çıkan IQ-dışı bazı etmenleri, kalıtsallığın kalıtımdan farkın ve sadece çevrenin genleri değil, genlerin de çevreyi seçmesini konuşuyoruz.
