For a long time, UX teams treated A/B testing as the only legitimate way to make causal claims. If you could not randomize users, you reported trends, correlations, or anecdotes and hoped stakeholders understood the limits. That mental model no longer fits how products actually evolve. Most meaningful UX changes cannot be cleanly randomized. They are rolled out gradually, constrained by infrastructure, shaped by policy, or deployed universally before research even begins. Qua

Imagine you are listening to a crowded room where several conversations are happening at once. You are trying to follow just one voice. At first, everything blends together: laughter from one corner, music in the background, fragments of unrelated sentences drifting past. To make sense of anything, your brain starts doing something remarkable. You focus on the voice you care about, the words that matter to you, the rhythm and tone that stay consistent, and you mentally tune o

Trying to do serious UX research with the wrong statistical tools is like trying to eat a bowl of soup with a fork. You can work very hard, take dozens of careful scoops, and still walk away hungry. The problem is not that UX data is unusable or too noisy. The problem is that we often analyze it with methods that were never designed for how human behavior actually unfolds. UX studies can be surprisingly efficient and informative when the analysis respects the structure of the

Most of us have been there, we run usability tests and see where people struggle, but we still do not quite understand how users think  about the product. Surveys give us numbers, but the answers feel thin or oddly constrained. At some point, someone suggests talking to users together, letting them react to each other, and seeing what emerges. That moment is usually when focus group interviews enter the picture, and depending on how they are used, they either bring clarity to
