Technology doesn't change the brain's fundamental mechanism for memory. Instead, it acts as an external tool that allows us to strategically choose what to remember, freeing up limited attentional resources. We've simply offloaded rote memorization (like phone numbers) to focus our mental bandwidth elsewhere.

Reducing the number of clicks is a misguided metric. A process with eight trivially easy clicks is better than one with two fraught, confusing decisions. Each decision burns cognitive energy and risks making the user feel stupid. The ultimate design goal should be to prevent users from having to think.
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.
Memory doesn't work like a linear filing system. It's stored in associative patterns based on themes and emotions. When one memory is activated, it can trigger a cascade of thematically connected memories, regardless of when they occurred, explaining why a current event can surface multiple similar past experiences.
The true cost of social media isn't just the time spent posting; it's the constant mental energy dedicated to it—planning content, checking engagement, and comparing yourself to others. Stepping away frees up significant cognitive "white space," allowing for deeper, more strategic thinking.
To remain effective, it's crucial to manage information consumption. The goal is to be aware of world events without drowning in them to the point of paralysis. Tools that create friction, like app blockers, can help maintain this balance and preserve the mental capacity for meaningful action.
The same technologies accused of shortening attention spans are also creating highly obsessive micro-tribes and fandoms. This contradicts the narrative of a universal decline in focus, suggesting a shift in what we pay attention to, not an inability to focus.
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.
Engaging in a low-stakes, repetitive game (like tower defense or solitaire) while performing a primary auditory task (like listening to raw tape) can prevent mental drift. This secondary activity occupies just enough cognitive space to keep the mind from wandering, thereby enhancing focus on the main task.
Small, recurring questions like "What's the Netflix password?" create constant interruptions and decision fatigue. Centralizing this information into a shared document or "hub"—from logins to takeout orders—acts as a brain dump, streamlining daily life and preserving mental energy for important tasks.
