What matters is the amount of confusion developers feel when going through the code. Confusion costs time and money. Confusion is caused by high cognitive load. It's not some fancy abstract concept, but rather a fundamental human constraint.
Since we spend far more time reading and understanding code than writing it, we should constantly ask ourselves whether we are embedding excessive cognitive load into our code.
Cognitive load is how much a developer needs to think in order to complete a task.
