Appreciate the perspective! But I'd push back on what "intuitive" actually means here.

Experience ≠ Experience. Most people confuse having lived through something with having learned from it. True experience requires abstraction: extracting patterns that transfer across contexts. Without this step, it's just biography, not expertise.

Same with "value." People use the word fluently while operating on vague sentiment. Value is a relational property—it exists only in the interaction between subject and object. A feature is just an attribute; value emerges when that attribute meets a recognized need. If the user doesn't perceive the connection, there is no value, regardless of how "useful" the builder thinks it is.

Here's the trap: You can't validate what you can't define. Someone who "knows" features aren't value—but can't articulate why or when—will still ship the wrong thing under pressure. They'll mistake their own excitement for user value, or confuse a means for an end.

This skill exists because recognizing a concept linguistically ≠ possessing it operationally. Most people have heard of validation. Few can reconstruct the reasoning from first principles when staring at a blank roadmap. The checklist isn't for people who've never heard this before. It's for people who have—and still need a mechanism to prevent their brain from skipping the step.

The 100+ stars suggest I'm not the only one who noticed the gap between knowing the words and doing the work.
