Before you ship that blog post or technical article, run it through this systematic gap finder. It separates blind spots (inherent limits of your approach) from blank spots (things you could add), and walks you through four frameworks including cognitive bias checks, Socratic questioning, and missing perspectives analysis. The anti-patterns section is especially useful, calling out "perfection paralysis" and "scope creep trap" as real hazards. What I like is it acknowledges you can't fix everything, you just need to know what you're leaving out. Best used on complete drafts, not works in progress.
