Tired of seeing if (!x) in code? This author argues it's not just a style issue, but a sign of poor software design. The problem, called "boolean blindness," happens when we stuff complex domain states into a simple true/false flag, making our code obscure and brittle.
Instead of generic flags, the better approach is to model the actual state of your system. By using descriptive methods and patterns that clearly state your business rules, you create code that's far easier to read, maintain, and change without introducing a bunch of new bugs.
