Cost of Multitasking
Multitasking is really task-switching — and every switch has a cost. A cognitive enhancement researcher separates the solid science of switch costs from the shaky claims of permanent focus damage, and shows how to switch less.

You have a deadline, you feel the dread, and you still open a new tab — then call yourself lazy. The neuroscience tells a different story. Procrastination is an emotion-regulation problem, not a discipline failure, and once you see what your brain is really doing, you can stop fighting the wrong battle.
The Dopamine-Motivation Connection: Why Will Power Isn’t the Problem
You know what you should be doing, and you still can’t start — so you blame your willpower. The neuroscience says otherwise. Motivation is a dopamine signal, not a character trait, and once you see how that signal actually works, the problem becomes an engineering task rather than a moral one.
Morning Routine for Productivity
The first hour after waking sets your whole day. A morning routine built on the actual science — light, the cortisol awakening response, hydration and movement — plus the right order to do it in.
Digital distraction and the Brain
You’re not weak-willed — apps are engineered to capture your attention. How digital distraction exploits the brain’s reward-learning system, the real cost of a phone’s mere presence, and why environment beats willpower.
Deep Work: The Neuroscience of Distraction-Free Productivity
Deep work isn’t a willpower problem — it’s an attention-protection problem. The real science of sustained focus, why the “23 minutes” myth is wrong, and the exact protocol Peter uses.
