A Thousand Brains: A New Theory of Intelligence by Jeff Hawkins

“In the architecture of the mind, every cortical column is writing its own story of the world.” — Jeff Hawkins

A Thousand Brains: A New Theory of Intelligence by Jeff Hawkins is a groundbreaking exploration of how the neocortex creates models of the world through thousands of parallel learning units called cortical columns. Building on decades of neuroscience and the author’s Hierarchical Temporal Memory framework, Hawkins proposes that intelligence arises not from a single unified model but from the collective voting of many independent models, each mapping features in reference frames. This theory reshapes our understanding of human cognition, offers a roadmap for more brain‑like AI, and illuminates how perception, memory, and planning emerge from the same underlying principles.

1️⃣ Intelligence as Prediction and Model‑Building  

Hawkins shows that the core function of the neocortex is to predict sensory input by building internal models. When predictions match reality, we experience understanding; mismatches drive learning. Actionable strategy: in daily tasks—like navigating a new route—pause to predict what you’ll encounter next, then compare your prediction to reality, sharpening your brain’s model‑building skills.

2️⃣ Cortical Columns as Independent Learners  

Each cortical column learns a complete model of objects or concepts within its sensory domain. Intelligence emerges from their collective consensus. Practical example: instead of relying on one source, gather multiple viewpoints when making decisions. Strategy: break complex problems into smaller components and seek independent solutions, then integrate them for a robust outcome.

3️⃣ Reference Frames Unify Sensory Inputs  

Columns use reference frames—location‑based coordinate systems—to link sensations (touch, vision, sound) into coherent object representations. Actionable tip: when learning new information, anchor it to multiple contexts (visual, spatial, emotional) to create richer mental reference frames that improve recall.

4️⃣ Sensorimotor Integration Drives Understanding  

Hawkins emphasizes that movement and sensation are inseparable: we learn objects by touching and moving around them. Strategy: adopt embodied learning techniques—use gestures, build physical models, or walk while brainstorming—to engage your sensorimotor system and deepen comprehension.

5️⃣ Sequence Memory Underlies Prediction  

Temporal sequences—like the steps in a process—are stored by columns as transitions between states. This sequence memory enables anticipation of what comes next. Actionable exercise: when mastering a new procedure, break it into small, repeatable steps and practice them in order, reinforcing your brain’s sequence‑learning mechanisms.

6️⃣ Attention as Selection of Reference Frames  

Attention focuses processing on particular columns and reference frames, enhancing prediction accuracy. Practical tip: use focused “attention sprints”—set a timer for 15 minutes of uninterrupted work on one task, minimizing distractions to strengthen your brain’s attentional networks.

7️⃣ Continuous Learning, Never Freezing the Network  

Unlike many AI systems, the brain never stops learning. Hawkins argues for architectures that learn continually without catastrophic forgetting. Strategy: incorporate spaced repetition into your study routines and review material at increasing intervals to mirror the brain’s continuous learning process.

8️⃣ Ensemble Decision‑Making from Model Consensus  

Columns vote on the most likely interpretation of sensory input, and the consensus becomes perception. Actionable strategy: when faced with a tough choice, solicit opinions from a diverse group—each person acting like a “column”—and make decisions based on the collective input rather than a single viewpoint.

9️⃣ Implications for AI: Toward Brain‑Like Architectures  

Hawkins critiques deep learning’s limitations and advocates for Hierarchical Temporal Memory (HTM) as a more biologically plausible alternative. Practical step: explore open‑source HTM frameworks (such as Numenta’s) to experiment with brain‑inspired AI models and stay abreast of emerging architectures.

🔟 The Promise of Understanding Consciousness  

By revealing how the neocortex builds multiple models and integrates them, Hawkins offers a path to demystify consciousness and develop machines that truly understand. Actionable idea: follow the latest research in neuroscience and cognitive science—subscribe to journals or attend webinars—to track progress toward mapping the brain’s unified theory of intelligence.

Simple Guide for Simple Happiness: 10 Ways to Be Happy

Happiness isn’t a destination but a daily practice, shaped by intentional choices and mindset shifts. In Simple Guide for Simple Happiness: 10 Ways to Be Happy (Most of the Time), Anna Brem Brigar offers a refreshing, no-frills roadmap to cultivating joy without chasing perfection. Unlike many self-help books that promise quick fixes or complex systems, Brigar’s approach is grounded in simplicity and authenticity, blending psychological insights with practical, everyday strategies.

 Her warm, conversational tone feels like advice from a wise friend, and her emphasis on sustainable habits over fleeting highs makes this guide both relatable and actionable. Brigar’s vulnerability, sharing her own struggles with stress and self-doubt adds depth, showing she’s not preaching from a pedestal but walking the path alongside readers. For anyone seeking to infuse more happiness into their routine without overwhelming changes, Simple Guide is a concise, uplifting companion that delivers.

Five Lessons from Simple Guide for Simple Happiness: 

    1. Happiness Thrives in Small, Intentional Moments:

Brigar teaches that joy doesn’t require grand gestures but can be found in small, deliberate acts like savoring a morning coffee or writing a gratitude note. She emphasizes creating “micro-moments” of happiness daily, such as taking a five-minute walk to reset, which cumulatively build a happier life. This approach makes happiness accessible, countering the myth that it depends on big achievements or perfect circumstances, and encourages readers to find joy in the ordinary.

    2. Reframe Challenges with a Growth Mindset:

Rather than letting setbacks derail happiness, Brigar advocates viewing them as opportunities for growth. Drawing on positive psychology, she suggests asking, “What can I learn from this?” when faced with difficulties. Her examples, like reframing a work mistake as a chance to improve, show how this mindset fosters resilience and maintains joy even during tough times, transforming obstacles into stepping stones for personal development.

    3. Prioritize Self-Care Without Guilt:

Brigar underscores that self-care whether through rest, exercise, or hobbies—is essential for sustained happiness, not a luxury. She addresses the guilt often tied to prioritizing oneself, offering practical tips like scheduling “me time” as non-negotiable. Her relatable stories of balancing family and personal needs highlight that self-care fuels energy and patience, enabling readers to show up better for others while nurturing their own joy.

    4. Build Connection for Deeper Joy:

Happiness is amplified through meaningful relationships, and Brigar encourages nurturing bonds with family, friends, or even strangers through small gestures like a heartfelt compliment or a shared laugh. She cites studies showing social connection boosts well-being, urging readers to initiate contact despite busy schedules. This lesson emphasizes that intentional, quality interactions, even brief ones, create a sense of belonging that sustains happiness.

    5. Practice Gratitude to Shift Perspective:

Brigar champions gratitude as a powerful tool to rewire the brain for happiness, referencing research that daily gratitude exercises increase optimism. She suggests simple practices, like listing three things you’re thankful for each night, to focus on what’s going well rather than what’s lacking. Her personal anecdotes of finding gratitude amidst stress illustrate how this habit can transform your outlook, making it a cornerstone of a joyful life.
