This Discourse was recorded at the Ri on 26 January 2024.

This innovative concept suggests that the brain operates as a dynamic prediction engine, continually shaping our perception of our bodies and the surrounding environment. Through a complex interplay of sensory data and expectations, the brain orchestrates every facet of human experience, from the everyday to the extraordinary.
In this thought-provoking Discourse, Andy will guide us through the inner workings of the predictive brain, exposing its profound implications for our well-being, mental health, and society. For instance, chronic pain and mental disorders often result from subtle disruptions in our unconscious predictions, offering promising avenues for more precise and effective treatments. As we scrutinise the boundaries between ourselves and the external world, we'll uncover the intricate connections between our environments, memories, thoughts, and emotions. This journey reveals perception as a carefully controlled form of 'controlled hallucination.'
Join us as we delve into the extraordinary explanatory power of the predictive brain. Discover how it revolutionizes our comprehension of perception and reality, all without resorting to hyperbolic language or clichés.

Andy Clark is a Professor of Cognitive Philosophy at the University of Sussex. His interests include artificial intelligence, embodied and extended cognition, robotics, and computational neuroscience. From 2017-2021 he was PI on a European Research Council Advanced Grant: Expecting Ourselves: Embodied Prediction and the Construction of Conscious Experience. He is PI on an ERC Synergy Grant, XScape and Material Minds: Exploring the Interactions between Predictive Brains, Cultural Artifacts, and Embodied Visual Search.

Discourses are one of the Ri’s oldest and most prestigious series of talks. Since 1825, audiences in the theatre have witnessed countless mind-expanding moments, including the first public liquefaction of air by James Dewar, the announcement of the electron by JJ Thomson and over 100 lectures by Michael Faraday. In more recent times, we have had Nobel laureates, Fields medal winners, scientists, authors and artists - all from the cutting-edge of their field. Discourses are an opportunity for the best and brightest to share their work with the world.
Steeped in nearly two centuries of tradition, a Discourse is more than just a lecture. The Discourse lasts exactly an hour, and a bell is rung to mark the beginning and end. To keep the focus on the topic, presenters begin sharply at 7:30pm without introduction and we lock the speaker into a room ten minutes ahead of the start (legend has it that a speaker once tried to escape!). Some of our guests and speakers dress smartly for our Discourse events to add to this sense of occasion. Read more about Discourses here: www.rigb.org/e...

Target tracking is a syntropic process! Making predictions is a syntropic process -- teleological. Syntropy (prediction) is dual to increasing entropy -- the 4th law of thermodynamics! Teleological physics (syntropy) is dual to non teleological physics (entropy). "Always two there are" -- Yoda. Concepts are dual to percepts -- the mind duality of Immanuel Kant.

Empiricism is a belief within epistemology... that is to say, it's part of a school of philosophy. Empiricism was created through philosophy. So for you to act like it's some novel feature for a philosopher to be empirically engaged is supremely ignorant. Locke, Berkeley, Hume - these were all philosophers, and they themselves laid the groundwork of empiricism. This is very much within the domain of philosophy, and always has been. Why, then, are you so impressed by this?

Some poorly understood chronic conditions really are somatically derived rather than model-driven.

What we believe is based upon our perceptions. What we perceive depends on what we look for. What we look for depends on what we think. What we think depends on what we perceive. What we perceive determines what we believe. What we believe determines what we take to be true. What we take to be true is our reality." - Bohm

It ismost useful for a neural system to retain consecutive inference of time. All nonchronnological reflection is useful for establishing salience, valence, and sensorimotor response to previously experienced sm responses. Do never forget that an energy-eater such as brain/neuron must primarily be useful. This is the constraint to which evolution responds. Organisms with motile young, when becoming sessile adults, absorb their no longer useful brains. All tissue is subject to this, muscle, vascular, even mitochondria within cells whose activity reduces. Think efficiency when questioning any variation.

My brother-in-law has been crippled by lower body pain for a few years now. He was an exercise addict and assumed he had injured his back so tried to get treatment, but the doctors -after extensive investigation- couldn't find any problem. He, naturally, insisted there was a problem and kept looking for answers. The doctors then went further and told him the pain was all in his head (not to say he was not actually in pain). Long story short, he rejected this idea and had a mental breakdown and was institutionalised by the family when he expressed suicidal intentions. He's since accepted he has a 'mental' illness but he is pretty much bed ridden, unless my wife wants to take him indoor climbing, where he suddenly can move almost normally, albeit slowly. The account presented in this lecture makes a lot of sense in his case. PRT sounds like a good option for him. Thanks Dr Clark!

I am neuro-divergent, ASD, and a higher sensitivity to light at a time of chronic stress began to cause me to experience chronic migraines over a period of about a decade. It was a trauma response following a period of extreme and prolonged stress. The high anxiety re-wired my brain for a while. Healing from the psychological trauma allowed my nervous system to calm down. I’m now experiencing fewer headaches and lowering of intensity. But it’s a process that has taken years and required help at the root cause, which was psychological and not physical.

So it erred on the side of a pain response until further evidence was obtained

I wonder how this could relate to the anecdotal recollections from people struggling with different psychiatric illnesses/afflictions, and their resulting radical shifts of perspective after taking (often accidentally) high dosages of hallucinogens. Not that the change is always good or bad, but just radical change in perspective in general. If the brain updates itself with this balance of "generative model" vs. "sensory input," it seems that radical perturbations to either really changes our "internal judge" that assigns weights to either. On the other side of the same coin would be when we receive extreme sensory input (which we are unable to immediately justify with our internal models), that would result in PTSD--where we now expect this input to occur again despite it being very unlikely. Could we perturb the system (either through modifying the internal model or by controlling sensory input) to recalibrate the judge?

They didn't say that the body damage isn't real, just that you can affect your perception of it. I have CFS, so I have first hand experience with this. Science has found physical and metabolic anomalies in the muscle tissues, so the disease is very much real and not "in your head". Similar anomalies were found in Long Covid patients. They have no clue about the how and why (yet), so there's nothing they can do to fix or alleviate the damage directly. However, having a positive or negative mental attitude and expectations towards the disease can make a lot of difference in how debilitating it is in daily life.

I hear you as someone who has gotten the "in your head" response from a doctor before but maybe it's more like "it's a lot more in our heads than we thought before but that doesn't mean it's at all easy to shift those processes". If anything, with the framework of the talk, processing difficulties have a stronger validation for their reality. They have to be taken just as seriously as a nail piercing a body because the brain makes sure that the pain is just as real. So instead of dismissal, psychiatrists have a duty to tackle so called "in our heads" problems with creativity and scientific soundness.

I think it should be stated CLEARLY that positive thinking and working to change brain patterns does NOT work on a lot of chronic pain people because there are MEDICAL reasons for the pain. I cannot tolerate pain medicine and, while I am able to manage my pain mentally on a daily basis, I am still in incredible pain. My pain levels have been tested and every single time they ask me how I'm even able to walk and function because I peg the machines out completely. My background includes years upon years of training and I was Even training for the Olympic Trials (swimming) before a truck ran into me and stopped my life. Swimming (any high level sport) is a lot of mental games to keep you going in high pain situations of grueling workouts. I'm lucky to have had that background, but my current walking pain level would put down the largest males. I've had 13 back surgeries of which 11 were performed WITHOUT anesthesia (I didn't tolerate it). I'm telling this because I have a great hold on mental control of my brain, but I'm still in horrible, horrible pain because the pain is medical. While some mental pain gymnastics can help some people, please do not insult any chronic pain suffering people by suggesting it's all in your head. We have been gaslighted enough and it never ends well.

Only a strong act of will could stop the jumping until help arrived. It turned out that someone had placed a large plank of wood on the basement floor with a nail sticking up through it.

What I've found is that when we go deeper into the mind, not the brain, there is a level of perception which is clear... for instance, seeing the future. The brain couldn't see the future unless it was considering such as probabilities. I'm talking seeing actual events which are beyond probability, beyond calculation. For instance, I foresaw an amusing event which was my brother dropping a £2 coin, on a certain street in Edinburgh. We don't live in Edinburgh, and I never knew he was going there that day. We just happened to bump into one another with our group of friends. Within minutes of meeting he was about to sneeze and pulled out a hanky, turning away from us, and out dropped a £2 coin. Yes, our everyday perception does work in a pretty deterministic manner, but that does not mean we are machines, nor limited to the factors of the past.

I think this subject is very interesting for many reasons. One of those is how it has direct bearing upon American politics. In America, politics is split between two camps. The right side generally claims authority due to reason. Their form of reason may be religion based, but it is thought derived from a previous lesson or understanding rather than thought derived from experience. The left takes more from experience, and downgrades the right's understanding. When there is no direct way to get feedback, because feedback is only being gathered in expected places native to a particular side, then reality falls too far outside of expectation and people don't know what to do with it. They become more easily afraid. They fall back on tried ways, even if they can see they don't work. When that happens in the brain, we see it because we have a sense of an observer. There isn't so much of that if the reasoning side can't prove itself and has to resort to legal and political tricks to get what it wants. In other words, it can't change any, so it makes up conspiracy theories to explain why it appears wrong. It's Plato and Aristotle played out all over again. It's Galileo and the church, sometimes. Other times, the right can save the state a lot of money. We still need to spend more on basic research, but we have come a long way with what we are doing.

I was commercial fishing and I stepped on the gaff hook. It went right through my boot and through my big toe. The fleshy part. I just taped it up with some Ichthammol and electrical tape and kept fishing. Never thought once about it and it healed up fine.

Really interesting info, especially in the current AI research climate. Would be enrichtacular to see cases of genetic abnormalities affecting perception of nature. Sure, autism, but what about people with malformed receptors and such? Are there people who don't get all the different brain waves? So many questions.

Making predictions is a syntropic process -- teleological. Syntropy (prediction) is dual to increasing entropy -- the 4th law of thermodynamics! Teleological physics (syntropy) is dual to non teleological physics (entropy). "Always two there are" -- Yoda. Concepts are dual to percepts -- the mind duality of Immanuel Kant.

Brains being a predictive self-preservation system, self awareness grows from self-preservation, and thus sentience, and so too sapience. I'd like to talk with this man sometime.

It’s almost like the brain or even maybe the entire nervous system, including the nerves and the spinal cord, would “examine” the set of receptor responses by comparing it (pairing it up) with the combined achieve of all the RELEVANT previously stored impression set accumulated from previous life experiences from the moment of conception. No wonder that this will appear to us as a prediction from that particular perspective but I would rather call this “the procedure of removing redundancies before storing (or normalizing) the new incoming stimuli for archival.” In order to recognise the similarity and subsequently remove the redundancy before storing, the nervous system runs the stimuli (thinking) until the brain flashes the previously stored case: if the overwhelming majority shows agreement, the system will take that similar memory segment as an increasingly precise and firm template and the result will be both the level of similarity and the set of differences. The system, at this point, somewhat modifies the memory and/or(?) starts a new one depending on the extent of both the similarity and difference. If a stimuli does not ring any bell, or contradicts with some, then we are surprised:) Are you?

If, autism leans toward an overload of sensory input and, I believe, conditions of psychopathy have an insensitivity to sensory input and a dominance of internal models, is it perhaps that the two condition are the reversals of each other, and normality a mid- point balanced between the two ?

I still ride motor cycle and do some physical work, Have worsened my condition over time and not sure my change in approach to its only pain not disfunction has been worth it sure it still hurts like a shin kicked into towbar and sometimes only hurts like a stubbed toe, (for reference broke distal carpal in right hand on motorcycle,( right hand does throttle and brake) then fixed it and rode it 160km to hospital for a 5 hour wait treated as sprain, the surprise at 3am on the radiographers face was expected, Ive done this pain thing a few times second time was only 60km Love the talk but doesnt really address the flip side of chronic pain and how taxing it is. lol my causes ( l5-S1, l4-l5, l3,l4 t5-t6 t6-t7....c2-c3 c5-c6 c6-c7 ) Be well and happy people

4:26 this prediction is super easy to understand when happening on vision or sound or such primary perception. However, the samething happens in higher cognition as well. Thats how villains in your life are created usually. Some situation might have made someone behave in certainway which made us unhappy and we just remember them like "convex face", as if it is a given attribute of the person. From then on, even if we see a concave face (good behaviour), our brain will tell us "it must be convex " (bad somehow). Thus we cookup a story to justify it and behave accordingly to that person. Meanwhile the same thing is happening to the other as well due to your behaviour to them. From there on, its all downhill. Both become bad people to each other. So dont see this just as a curious experiment. Learn to see how it bites you in daily life!

this explains very well why people who have dmt breakthroughs have these crazy experiences. Drugs literally "drug" the brain to make it slow in it's perception of reality. That's why no matter how many things are seen on this "episodes" they are always similar things to what we have seen in our lives.
