Spencer Greenberg speaks with Anil Seth about how our perception of reality and self is a brain-based construction, not a direct reflection of the world. They discuss perceptual diversity, the utility-driven nature of experience, and the deep connections between art and science as creative enterprises.
Actionable Insights

1. Meditate for Self-Awareness

Engage in meditation to gain distance from your mental processes, observe how thoughts and attention unfold, and recognize that selfhood is part of a continuous flow of experiences, not a fixed entity.

2. Challenge the ‘Essential Self’

Question the intuitive feeling that there is a single, unchanging essence of ‘you’ deep within, understanding instead that the self is a collection of perceptions and experiences that can be teased apart.

3. Perception as Controlled Hallucination

Adopt the mental model that perception is a ‘controlled hallucination,’ recognizing that your brain constructs your reality not for accuracy, but for utility and survival in the world.

4. Understand Perceptual Diversity

Cultivate humility about your own perceptual experience by realizing that what you experience is dependent on your unique mind and brain, leading to an understanding that others may see, experience, and believe different things.

5. Use Optical Illusions for Insight

Engage with optical illusions to observe how your brain actively constructs reality, reinforcing the understanding that all experience is a brain-based construction, not a direct reflection of external reality.

6. Reframe Perception’s Goal

Shift your understanding of perception’s purpose from accuracy to utility, recognizing that your brain constructs reality in ways that are useful for survival and effective behavior, even if systematically different from what’s objectively there.

7. Participate in Perception Census

Contribute to scientific research on perceptual diversity by participating in the online Perception Census (anilseth.com or search ‘perception census’) to help map how different our inner worlds are across various sensory experiences.

8. Normalize Hearing Voices

Recognize that hearing voices in one’s head is not uncommon and often not distressing, which can help normalize the experience and prevent quick diagnoses of difference as deficit, avoiding unnecessary fear or stigma.

9. Recognize Imagery Variation

Understand that people vary widely in their capacity for internal mental imagery (from vivid to aphantasia), and that these differences typically have little to no impact on functional capacity, only on the diverse ways problems are solved.

10. View Art & Science as Complementary

Appreciate art and science as deeply intertwined, creative enterprises that both seek to understand our place in nature, recognizing how artistic aptitude can inform scientific discovery and how art can reveal insights into perceptual systems.

11. Reflect on Social Media’s Impact

Consider how prolonged engagement with highly stimulating, short-form social media content (e.g., TikTok) might cultivate ADHD-like behaviors or mindsets, potentially influencing attention and information processing.

12. Utilize ThoughtSaver for Recall

Use the free tool ThoughtSaver.com to strengthen your recall of important ideas by receiving daily flashcard quizzes, either from ready-made decks or by creating your own to remember valuable information.

13. Seek Mind-Expanding Experiences

Engage in experiences (like the ‘dream machine’ described) that highlight the mind’s power to generate experience, fostering a profound appreciation for the complexity, wonder, and potential of your own brain and its unique processes.
