The Science of Focus & Productivity
Dive into the science of focus, fatigue, and flow. We connect foundational research and modern neuroscience to reveal how human productivity really works.
Part 1: The Foundational Science
Pioneering 19th and early 20th-century research that proved our bodies follow biological rhythms and revealed the true cost of mental fatigue.
