Scientific literature suggests humans have between 22 and 33+ physiological senses, including balance, proprioception, and awareness of internal states like bladder fullness. This reframes human potential, suggesting we are capable of perceiving far more than we commonly acknowledge.

Neuroscientist Rachel Herz argues the sense of smell is profoundly undervalued. Its loss warrants massive compensation because the brain regions for smell, emotion, and memory are intertwined. Losing smell can lead to severe depression and a disconnected sense of self, making it far more debilitating than commonly believed.
Our perception of sensing then reacting is an illusion. The brain constantly predicts the next moment based on past experiences, preparing actions before sensory information fully arrives. This predictive process is far more efficient than constantly reacting to the world from scratch, meaning we act first, then sense.
The ability to "smell" an illness, like an ear infection or Parkinson's, is not about detecting a universal "sick" odor. It is about recognizing a change from an individual's unique baseline body scent. This skill, once used by doctors, highlights the importance of familiarity in using scent for diagnostic purposes.
Contrary to popular belief, intuition isn't just a "gut feeling" or brain pattern. Research, particularly from trauma studies like "The Body Keeps the Score," shows that wisdom and life patterns are physically embedded in the body's fascia and musculature.
Vision, a product of 540 million years of evolution, is a highly complex process. However, because it's an innate, effortless ability for humans, we undervalue its difficulty compared to language, which requires conscious effort to learn. This bias impacts how we approach building AI systems.
Labels like 'imposter syndrome' or 'feeling like a failure' are purely mental stories, not physical realities. Your body doesn't know what 'failure' is; it only experiences sensations like a churning stomach or tightness in the chest. By focusing on the raw physical feeling, you disconnect from the mind's debilitating narrative.
The concept of a universal "attention span" is a myth. How long we focus depends on our motivation for a specific task, not a finite mental capacity that gets depleted. This reframes poor attention from an innate inability to a lack of interest or desire.
We don't perceive reality directly; our brain constructs a predictive model, filling in gaps and warping sensory input to help us act. Augmented reality isn't a tech fad but an intuitive evolution of this biological process, superimposing new data onto our brain's existing "controlled model" of the world.
The Fetus GPT experiment reveals that while its model struggles with just 15MB of text, a human child learns language and complex concepts from a similarly small dataset. This highlights the incredible data and energy efficiency of the human brain compared to large language models.
Kevin Rose describes discovering he has aphantasia, a condition where one cannot voluntarily visualize mental images. For these individuals, abstract concepts and memories are experienced through feelings and kinesthetics rather than vivid pictures, highlighting vast, often unknown, differences in human cognition.
