Myth-bust: "Only test one variable at a time"

Myth-bust: "Only test one variable at a time"

The lab-science rule cripples creative testing. Ads aren't molecules.

— The myth: isolate one change so you know what moved the needle
— The correction: single-variable testing burns budget chasing micro-lifts while whole new concepts go untested
— What to steal: test concepts against concepts, not hook-A vs hook-B of the same tired idea
— Why it works: the biggest wins come from a different angle entirely, never from a recolored button

🔥 Pick of the week: ship five genuinely different concepts, kill four fast, then iterate the survivor. Breadth first, depth second.
