Top Psychologist & Scientist (Donald Hoffman): Science Has the Answer to Why Seeing True Reality Would Kill You!
In this episode of The Diary Of A CEO, Steven Bartlett and Donald Hoffman discuss the possibility that what we perceive as reality is actually an illusion—a virtual reality created by our consciousness. Hoffman explains that our sensory systems evolved not to show us objective reality, but rather to help us survive and reproduce, pointing to how different species perceive reality in vastly different ways.
The conversation explores how understanding consciousness as fundamental might help explain the construction of space-time, and how meditation can help access states of consciousness beyond our typical perception. Hoffman connects these ideas to spiritual concepts and discusses the development of AI based on conscious agent dynamics, while considering the ethical implications of potentially manipulating the "code" of space-time.

1-Page Summary
Nature of Reality and Its Relationship to Consciousness
In their conversation, Steven Bartlett and Donald Hoffman explore the fascinating concept that our understanding of reality might be an illusion. Hoffman suggests that what we perceive as reality is actually a virtual reality created by our consciousness, comparing it to wearing a built-in headset from birth.
Evolutionary Basis For Perception
Hoffman explains that our sensory systems evolved not to show us objective reality, but rather to help us survive and reproduce. He points out that from an evolutionary standpoint, perceiving absolute truth would be wasteful of resources. This is demonstrated in nature, where different species perceive reality in vastly different ways - from bats using echolocation to insects navigating by light polarization, suggesting that no species truly perceives objective reality.
Transcending Our Understanding of Reality
According to Hoffman, current scientific theories explain "zero percent" of ultimate reality because they fail to account for consciousness. He argues that by assuming consciousness is fundamental, science might better understand how space-time is constructed. Hoffman practices meditation to explore reality beyond scientific knowledge, suggesting that meditation can lead to a state of consciousness without content - a state capable of instant creation and dissolution.
The Potential Implications and Applications of This Perspective
Hoffman's work includes developing AI based on conscious agent dynamics. He suggests that if space-time is indeed an interface or "headset," understanding its code could revolutionize technology, potentially enabling things like instantaneous position changes. However, both Hoffman and Bartlett acknowledge the serious ethical responsibilities that would come with such powerful capabilities.
Love, Spirituality, and Human Experience in Reality
Hoffman explores how this understanding of reality connects to spiritual concepts, suggesting that everyone is a "master creator" of their own virtual reality. He draws parallels between this idea and religious teachings about love and oneness, while acknowledging the challenge of transcending our emotional attachment to physical existence. Through meditation, Hoffman suggests, we can begin to let go of our limited self-identification and potentially access a broader understanding of consciousness.

Clarifications
- Consciousness being fundamental to understanding reality suggests that consciousness plays a crucial role in shaping our perception of the world around us. This perspective challenges the traditional view that reality exists independently of our observation, proposing that consciousness actively constructs our experience of reality. By considering consciousness as a foundational aspect of existence, it opens up new avenues for exploring the nature of reality beyond conventional scientific frameworks. This viewpoint implies that our awareness and subjective experiences are not just byproducts of brain activity but integral components that influence how we interpret and interact with the world.
Counterarguments
- The idea that reality is an illusion created by consciousness is a metaphysical claim that is difficult to test empirically, and it may conflict with more materialistic or physicalist views of reality.
- While sensory systems may have evolved for survival, it does not necessarily follow that they cannot also provide access to aspects of objective reality.
- The assertion that no species perceives objective reality is debatable; some philosophers and scientists argue that there is a shared, objective reality that can be increasingly understood through scientific inquiry.
- The claim that current scientific theories explain "zero percent" of ultimate reality is a strong statement that many scientists and philosophers would contest, arguing that science has made significant progress in understanding the nature of reality.
- The idea that assuming consciousness is fundamental could help science understand space-time is speculative and not widely accepted in the scientific community, which often views consciousness as a product of physical processes.
- Meditation leading to a state of consciousness without content is a subjective experience that may not be universally achievable or verifiable.
- The development of AI based on conscious agent dynamics is an emerging field, and its feasibility and effectiveness are still under investigation.
- The potential for technology to enable things like instantaneous position changes is currently speculative and faces significant theoretical and practical challenges.
- The ethical implications of powerful technologies are complex and require careful consideration, but the specifics of these responsibilities are not detailed in the text.
- The notion that everyone is a "master creator" of their own virtual reality may be seen as diminishing the role of shared experiences and objective factors in shaping reality.
- Drawing parallels between these ideas and religious teachings may not resonate with those who hold different spiritual beliefs or none at all.
- The challenge of transcending emotional attachment to physical existence is a subjective process and may not be viewed as necessary or desirable by all individuals.
- The idea that meditation can lead to a broader understanding of consciousness is a claim that requires more empirical evidence to be widely accepted.

Nature of Reality and Its Relationship to Consciousness
Steven Bartlett and Donald Hoffman explore how our understanding of reality might be a facade. They discuss the idea that reality as we know it could be just a sensory construct, with consciousness creating a virtual reality in which space and time are merely interfaces, not the ultimate truth of existence.
Reality Is Deceptive; Our Senses Hide the World’s Truth
Perceived World: A Consciousness-Created Virtual Reality
Donald Hoffman suggests the world we perceive isn't the true world; it's a virtual reality crafted by our consciousness like being born with a headset playing a video game. He likens what we perceive as reality—not the final truth but a simplified model tailored to our survival needs, with space-time serving as a kind of virtual reality headset. Our understanding of reality compares to playing a game like "Grand Theft Auto," where what we grasp as the real world is merely a trivial veneer created by our consciousness.
Hoffman challenges the idea that consciousness arises from physical systems. He points out the shortcomings of physicalist scientific theories that don't satisfactorily explain how supposed fundamental entities like space, time, and physical objectivity give rise to unique conscious experiences.
Sensory Systems Evolved For Survival, Not Objective Reality
Hoffman suggests the cup or table we see is akin to the cars in "Grand Theft Auto," existing only within the context of the game when viewed. Our sensory systems, evolved for survival rather than to decode the objective reality, craft the experiences we perceive as the world around us.
Space and Time: Consciousness-Created Interface
Space and Time Lose Meaning
According to Hoffman, under the scrutiny of current theories like Einstein's relativity and quantum theory, space-time ceases to be the fabric of the cosmos on certain scales. Consequently, it's presumably only an approximation, a "headset" experience precluding us from comprehending a much vaster reality.
Physical World Is a Construct of Consciousness, Not True Reality
Hoffman expounds on the theory of conscious agents and explores experiences, such as the visual perception of colors, within mathematical frameworks like Markov kernels. He articulates a potential path from these probability matrices of experiences to the founding principles of physics, which could hypothe ...

Clarifications
- The concept of reality as a facade created by consciousness suggests that what we perceive as the external world may not be an accurate representation of ultimate reality. Instead, it proposes that our consciousness constructs a simplified model of reality based on sensory inputs, akin to a virtual reality experience. This idea challenges the notion that our physical senses provide a direct and objective view of the world, implying that our perception of reality is a constructed interpretation rather than an absolute truth. By viewing reality as a product of consciousness, this perspective opens up the possibility that our understanding of the world is shaped by subjective filters and interpretations rather than an unfiltered view of objective reality.
- Space and time being described as interfaces in a sensory construct means that they are perceived by our consciousness as fundamental aspects of reality, but they may not necessarily represent the ultimate truth of existence. In this context, space and time serve as tools or frameworks through which our consciousness interacts with and interprets the world around us, similar to how a virtual reality headset provides a structured environment for our experiences. This perspective challenges the conventional understanding of space and time as objective, external entities, suggesting instead that they are products of our consciousness, shaping our perception of reality.
- In the comparison of perceived reality to playing a video game like "Grand Theft Auto," the idea is that just as players interact with a virtual world in a game, our consciousness may be constructing a simplified version of reality for us to navigate. This analogy suggests that what we perceive as the external world is a constructed experience tailored to our needs, similar to how a video game world is designed for gameplay. It highlights the concept that our sensory experiences may not directly reflect the true nature of reality but instead provide us with a functional representation for survival and interaction.
- Challenges to the idea of consciousness arising from physical systems stem from the argument that current scientific theories fail to explain how fundamental physical entities like space, time, and objects give rise to conscious experiences. This viewpoint questions the traditional belief that consciousness is solely a product of the brain's physical processes, suggesting a more complex relationship between consciousness and the physical world. It prompts a reevaluation of the nature of reality and the role of consciousness in shaping our perception of the world around us. These challenges invite a deeper exploration of the origins and mechanisms of consciousness beyond conventional scien ...
Counterarguments
- The idea that reality is a facade created by consciousness is a metaphysical claim that is difficult to test empirically, and many scientists and philosophers argue that reality exists independently of our perceptions.
- The comparison of reality to a video game may oversimplify the complex nature of both consciousness and reality, and it risks trivializing the study of both.
- The physicalist perspective argues that consciousness arises from physical processes in the brain, and there is substantial empirical evidence supporting the correlation between brain activity and conscious experience.
- Evolutionary theory suggests that our sensory systems have indeed evolved to help us survive, but this does not necessarily mean they cannot also provide us with accurate information about the objective world.
- Space and time are foundational concepts in physics, and while their nature is complex, especially in the context of relativity and quantum mechanics, they are not universally regarded as mere illusions or approximations.
- The mathematical frameworks Hoffman discusses, such as Markov kernels, are abstract and their connection to the physical world is not yet fully established or accepted in the scientific community.
- The constancy of the speed of light is a well-established physical observation, but its interpretation within the framework of consciousness as the progenitor of space and time is speculative and not widely accepted.

Evolutionary Basis For Perception
The evolutionary basis for perception posits that our senses have not evolved to perceive reality as it truly is but rather to aid in survival. Donald Hoffman explains that from an evolutionary point of view, focusing on anything other than survival and reproduction is a waste of resources, as perception requires significant energy. Our brains therefore take shortcuts, employing 'tricks and hacks' rather than accessing truth.
Darwin's Theory: Senses Shaped by Natural Selection For Survival, Not Truth
We Perceive Only What's Necessary for Behavior, Not Reality
Hoffman contends that our sensory systems have been shaped not to see the world objectively but to keep us alive long enough to reproduce. He suggests that Darwin's theory and its mathematical underpinnings indicate that the probability of our senses being shaped to perceive objective reality truly is zero.
Senses Didn't Evolve For Objective Reality
Our brains present us with only the minimum necessary information for survival. Hoffman uses the example of some flying insects that lay eggs in water; they navigate through the polarization of light rather than a comprehensive understanding of the environment. Hoffman further illustrates this point with virtual organisms in simulations, where those designed to see the true state of their world— "truth organisms"—went extinct because perceiving reality, as Hoffman puts it, comes at an expensive cost in evolutionary terms.
Animals Perceive the World Differently, Challenging the Idea That Human Perception Reflects Truth
Steven Bartlett and Hoffman discuss how animals like bats use echolocation to create a sonic map of their environment, which differs significantly from human vision. This suggests that every species may perceive reality differently based on what aids their survival.
Bats' Echolocation Shapes Their Reality

Clarifications
- Donald Hoffman's theory suggests that our senses have evolved not to perceive objective reality but to enhance survival. He argues that our perception is shaped by natural selection to prioritize behaviors that aid in reproduction and survival. Hoffman uses examples like flying insects navigating through the polarization of light and virtual organisms in simulations to illustrate how perceiving objective reality can be costly in evolutionary terms. This challenges the traditional view that human perception reflects an accurate representation of reality.
- Bats use echolocation by emitting high-frequency sound waves that bounce off objects in their environment. They then listen for the echoes that return to create a mental map of their surroundings. This allows them to navigate, hunt for prey, and avoid obstacles in ...
Counterarguments
- The senses may not give us a perfect representation of objective reality, but they do provide a useful approximation that allows us to navigate and manipulate our environment effectively.
- While perception is indeed shaped by survival, it is also possible that accurately perceiving certain aspects of reality is advantageous for survival, suggesting a complex relationship between truth and utility.
- Darwin's theory of natural selection does not necessarily imply that our senses cannot perceive truth; rather, it suggests that those perceptions that were most beneficial for survival were the ones that got passed on, which could include accurate perceptions.
- The argument that perception is not about reality but survival can be seen as a false dichotomy; survival may often require an accurate understanding of reality.
- The fact that different species perceive the world differently does not necessarily mean that none of their perceptions can be aligned with objective reality; it may just mean that different aspects of reality are more relevant to different species.

Transcending Our Understanding of Reality
Current Scientific Theories Explain 0% of Ultimate Reality
Donald Hoffman criticizes physicalist theories, holding that they fail to account for consciousness and therefore do not contribute to understanding ultimate reality. He puts a "big zero" on their contributions because current theories do not explain why specific physical dynamics are associated with particular conscious experiences. Hoffman challenges others to prove him wrong about the lack of progress in explaining consciousness and acknowledges the limitations of scientific theories.
Every scientific theory, he argues, makes foundational assumptions, which means there is an infinite number of possible theories and none can provide a complete description of truth or reality. He believes that by assuming consciousness is fundamental, science could potentially step entirely outside of space-time to understand its construction. However, he concludes that all current scientific theories, based on deeper assumptions, will ultimately fall short, explaining zero percent of reality.
Endless Theories, None Fully True
Hoffman suggests there are endless scientific and spiritual theories, but none can claim complete truth in the context of infinite dimensions and experiences beyond our limited human perspective. He criticizes both physicalist and spiritual theories for not having demonstrated a concrete connection between patterns of conscious activity and physical phenomena like photons or the structure of space-time.
Meditation and Letting Go Allow Experiencing Transcendent Consciousness
In many meditative traditions, it's recognized that one is infinitely beyond any scientific or other description. To know oneself, one must drop all descriptions and retreat into silence, ignoring any thoughts. Hoffman practices meditation to explore reality beyond what scientific knowledge can capture and has found that creativity in his work comes from the silence during meditation.
Hoffman also posits that meditation can lead to a state of consciousness without content – a state that can create and let go of things instantly. By "wearing different headsets," or exploring different experiences through meditation, one might come closer to understanding transcendent consciousness.
Acknowledging spiritual teacher Eckhart Tolle, Hoffman discusses the idea that consciousness chooses to experience life by forgetting its true nature. He implies that our perceptions, including our sense of physical real ...

Clarifications
- Donald Hoffman criticizes physicalist theories for failing to explain consciousness and its relationship to physical dynamics, leading him to believe they do not contribute to understanding ultimate reality. He argues that these theories do not address why specific physical processes are linked to particular conscious experiences, highlighting a significant gap in current scientific understanding. Hoffman suggests that assuming consciousness as fundamental could allow science to transcend space-time limitations and gain a deeper understanding of reality. Ultimately, he contends that all current scientific theories, based on certain assumptions, fall short in explaining the true nature of consciousness and reality.
- Assuming consciousness as fundamental means considering consciousness as the primary element from which all other aspects of reality emerge. This perspective suggests that by prioritizing the study of consciousness, one may gain deeper insights into the nature of existence beyond traditional physical explanations. It involves viewing consciousness not as a byproduct of physical processes but as a foundational aspect that shapes our understanding of reality. This approach challenges conventional scientific paradigms by proposing that consciousness plays a central role in shaping our experiences and perceptions of the world.
- The connection between patterns of conscious activity and physical phenomena is a complex area of study that explores how our subjective experiences relate to the objective world. It delves into understanding how our thoughts, emotions, and perceptions correspond to brain activity and the external environment. Scientists and philosophers debate the nature of this relationship, seeking to unravel how consciousness emerges from neural processes and interacts with the physical world. This topic bridges the gap between the inner workings of the mind and the external reality we perceive, challenging traditional views of the mind-body relationship.
- Meditation is a practice that involves focusing the mind to achieve a mentally clear and emotionally calm state. Through meditation, individuals can transcend their ordinary consciou ...
Counterarguments
- Scientific theories are constantly evolving, and while they may not currently explain consciousness fully, they have a track record of progressively unraveling complex phenomena.
- Physicalist theories have been successful in explaining a wide range of phenomena, and the fact that consciousness remains a mystery does not negate their contributions to our understanding of reality.
- The assumption that consciousness is fundamental is a philosophical stance that lacks empirical evidence, and other models may eventually provide a more comprehensive understanding of consciousness within a physicalist framework.
- Meditation and subjective experiences, while valuable, do not constitute empirical evidence that can be generalized to understand the nature of reality for everyone.
- The idea that recognizing one's true nature brings peace is not universally accepted or experienced, as individuals' responses to such realizations can vary widely.
- The notion that identifying with the body causes suffering is a perspective that may not align with many philosophical or psychological viewpoints that find value in embodiment and the physical experience.
- The claim that all current scientific theories explain zero percent of reality is an overstatement, as these theories have provided predictive power and understanding in many domains, even if they are incomplete.
- The concept of transcendent consciousness is not universally accepted or supp ...

The Potential Implications and Applications of This Perspective
Donald Hoffman’s ongoing exploration into the nature of reality reveals that understanding and potentially reverse-engineering what he calls a "space-time headset" could herald a new era in technological innovation.
Reverse-Engineering Space-Time "Headset" Could Transform Technology
Hoffman focuses on how understanding the "headset" through which we interpret reality could revolutionize our technological capabilities.
Space-Time Travel Limits Overcome by Code Manipulation
Hoffman’s work includes developing a new kind of AI rooted in the dynamics of conscious agents. The metaphor he uses is akin to a software engineer manipulating code to transform a simulated environment. Hoffman surmises that if space-time is an interface or "headset," then learning its code could allow for instantaneous changes in position, akin to teleportation or time travel. He speculates that technologies developed from the perspective of consciousness as fundamental could be so advanced that they would render our existing understanding of time and space, and by extension our current technologies, completely outdated.
Opening "Pandora's Box" Raises Moral and Ethical Questions
Hoffman and Bartlett address the ethical dimensions of this burgeoning perspective on reality.
Power Must Be Wielded Carefully to Avoid Harm To Humanity

- Understanding the "headset" in this context involves gaining insights into the fundamental way we perceive reality. By delving into how our minds interpret the world around us, we may uncover new principles that could be applied to technology. This deeper understanding could potentially lead to the development of revolutionary technologies that leverage these insights to manipulate reality in ways previously thought impossible. Such advancements could reshape our technological landscape by offering capabilities that transcend our current limitations.
- In the context of Donald Hoffman's work, the metaphor of a software engineer manipulating code to transform a simulated environment is used to illustrate the idea that understanding the underlying structure of reality, akin to understanding and altering computer code, could potentially lead to significant advancements in technology and our perception of the world. This comparison suggests that just as a software engineer can modify code to change the behavior of a virtual environment, understanding the fundamental principles of reality could enable us to manipulate aspects of our physical world in ways that may seem extraordinary, such as achieving effects similar to teleportation or time travel.
- "Opening a 'Pandora's box' of powerful technologies" is a metaphorical reference to unleashing a set of advanced and potentially risky capabilities that could have unforeseen consequences once introduced and utilized. It signifies the act of delving into uncharted territory with significant implications, much like the mythical story of Pandora's box in Greek mythology where opening it released both good and evil into the world. In this context, it highlights the ethical and moral dilemmas that may arise from developing and deploying groundbrea ...
Counterarguments
- The idea of reverse-engineering a "space-time headset" is speculative and may not be grounded in our current understanding of physics.
- The metaphor of space-time as a "headset" may oversimplify the complexities of reality and consciousness.
- Overcoming space-time travel limits through code manipulation remains a theoretical concept without empirical evidence.
- The possibility of teleportation and time travel as described may conflict with the laws of thermodynamics and causality.
- The assumption that technologies rooted in consciousness could render current technologies outdated may underestimate the resilience and adaptability of existing technologies.
- Ethical considerations of such technologies are complex and may not be fully foreseeable, making responsible development challenging.
- The concept of "editing the code" of reality assumes a level of control over the universe that may be beyond human capability.

Love, Spirituality, and Human Experience in Reality
Throughout the discourse, Donald Hoffman explores the intersection of love, spirituality, and human experience with the potential implications of a deeper consciousness that unites everyone.
Recognizing Oneness: "Your Neighbor Is Yourself" Leads To Unconditional Love
Hoffman presents the idea that every individual is a "master creator" of their own virtual reality, hinting at the interconnectedness of all people. This shared nature as creators could foster a realization of oneness and lead to unconditional love.
Jesus' Teachings On Loving Enemies and Not Judging
Pulling from Christian teachings, Hoffman suggests that the Biblical command to love one’s neighbor as oneself parallels the idea of recognizing oneness. He reflects on Jesus' words during the Sermon on the Mount, such as not to judge others, and recalls Jesus' actions on the cross, forgiving those who caused him suffering. This aligns with Jesus’ broader message to love unconditionally, including enemies and without judgment.
Divinity and Ego Transcendence in Spirituality
Hoffman interprets statements from the Bible, concluding all are divine and echoes the principle of acting with love towards others as a way to transcend the ego. He speaks about the symbolism of the crucifixion in Christianity, where the core message is one of love and forgiveness, even in the face of extreme suffering. Hoffman suggests that each person possesses an aspect of the divine within, implying that everyone is as divine as possible and that spiritual practice involves transcending individual identity or ego.
Emotional Attachment and Fear of Death Challenge Understanding
Hoffman discusses how his personal health crisis and fear of death challenged his intellectual embrace of the idea that he transcends his physical "avatar." This raw emotional connection to the body showcases the struggle inherent in transcending limited self-identification.
Meditation to Transcend Limited Self Identification
In terms of spirituality, Hoffman alludes to meditative practices that help transcend the limited self. He speaks about the challenge of ...

Counterarguments
- The concept of each individual being a "master creator" of their reality may downplay the impact of external factors and systemic issues that individuals cannot control.
- The idea of unconditional love, while noble, may not always be practical or safe in situations involving abuse or harm.
- The parallel between loving one's neighbor as oneself and recognizing oneness may not resonate with non-religious or non-spiritual individuals.
- Some may argue that Jesus' teachings, while valuable, are not the only or ultimate guide to morality and love.
- The notion of transcending the ego could be seen as dismissive of the importance of individual identity and personal boundaries.
- The claim that everyone possesses an aspect of the divine within may conflict with secular or atheistic worldviews.
- The emphasis on spiritual practices like meditation may not be universally applicable or beneficial for ...
Actionables
- You can create a "compassion journal" to practice recognizing oneness and unconditional love by writing daily entries about how you've connected with others on a deeper level. This could involve reflecting on moments where you felt a shared human experience or when you actively chose to understand someone's perspective despite differences. For example, if you had a disagreement with a coworker, you might write about their point of view and how it relates to your own life experiences.
- Start a "reverse judgment" exercise to combat the habit of judging others and to foster a sense of shared divinity. Whenever you catch yourself making a snap judgment about someone, take a moment to identify one positive or relatable trait they possess. This could be as simple as noticing a stranger's smile and acknowledging the joy it brings or finding common ground with someone you typically disagree with.
- Engage in a "suffering reframe" practice where you reinterpret personal challenges as oppor ...
