Cognitive Load in Software Development: Understanding and Managing Developer Mental Effort
By

Kettled twice. Extra chewy, extra trustworthy.
Summary
This GitHub repository presents a comprehensive guide to cognitive load in software development, arguing that cognitive load is the fundamental factor affecting developer productivity and code quality. The document explains that confusion in codebases stems from high cognitive load, which is a real human constraint rather than an abstract concept. It covers different types of cognitive load (intrinsic, extraneous, germane), provides practical strategies for reducing cognitive load in codebases, and offers tools and techniques for measuring and managing cognitive load in development teams. The content emphasizes that understanding and optimizing for cognitive load is more important than following specific programming patterns or methodologies.
Key quotes
· 4 pulledConfusion is caused by high cognitive load. It's not some fancy abstract concept, but rather a fundamental human constraint.
Cognitive load is what matters. It's not some fancy abstract concept, but rather a fundamental human constraint.
We need something more fundamental, something that can't be wrong.
Sometimes we feel confusion going through the code. Confusion costs time and money.
