⚖️ Design decisions need 5x more justification

Hey 👋

The dangerous moment in page sign-off is when your HTML breaks silently. The browser won't read it. You won't know until after ship, and by then the cost is credibility.

This week: a free test that catches it before sign-off, a name for the structural bias that makes design decisions take 5x longer to approve, and a two-line gate that stops underpowered tests from shipping.

Three things worth your attention this week:

Build: Test browser read-aloud before sign-off and treat silence as broken HTML.

Shape: Name what counts as good enough evidence before your next review.

Ship: Add "Practical threshold:" and "Act if:" before running any test.

Top 3 this week 👇

Build: Your Browser Can Already Speak a Page ↗

Treat browser silence at sign-off as a broken HTML report, not a quirk.

Why: A page that won't speak at sign-off has broken HTML structure and accessibility failures ready to ship.

Adopt: Run browser read-aloud before you sign off a page. If it won't speak, something in your markup needs fixing.

Shape: The Justification Tax ↗

Name your evidence threshold before design review starts, or lose the room.

Why: It costs you the ideas designers stop pitching because the approval bar is too high to clear.

Adopt: Before your next design review, add one row to your spec: "Evidence we'd accept." Fill it in before the session starts.

Ship: Statistical Significance Isn't the Same as Practical Significance ↗

Statistically significant doesn't mean practically important.

Why: Statistical significance means you ruled out luck, not that the effect is large enough to act on.

Adopt: Before running any test, add two lines to your task description: "Practical threshold: / Act if:"
