summary
Argues that reading code is undervalued and uses cognitive science (fMRI evidence and Miller’s law about 5–9 items) and mental-model theory to explain why. Recommends concrete practices—regular code review and contributing to open source—and illustrates them by analyzing a real GitHub PR that touched 22 files, added Selenium, missed CI checks, contained dead helpers and tests without assertions, and exposed hidden design and pattern problems.
