Quantified Self
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
The practice of using technology (such as wearables and apps) to collect various personal data (sleep, steps, heart rate, time expenditure) to understand oneself and improve life through quantification. It serves as a scaffold for digital self-management and a tool to counter perceptual bias. For example, you may think you slept well, but data reveals insufficient deep sleep; you may think you are working hard, but data shows you are actually slacking off.
