The first answer is
almost never the right one.
Every engagement I've run has had a moment where the obvious diagnosis turned out to be the surface of a deeper problem. The client who thinks their ads aren't working. The agency that thinks they need better creative. The contractor who thinks they lost the bid on price. In almost every case — the real problem was something nobody had looked at yet.
This is the thing about stopping at one run: you get the answer that was easiest to find. You don't get the answer that's actually true. A restaurant I worked with had been told by two different agencies that the problem was their social media presence. More posts. Better photos. Stronger hashtags. So they paid for more posts, took better photos, used stronger hashtags. Nothing changed.
When I looked at it properly — not just the Instagram account, but the website, the review platforms, the search behavior, the competitive landscape — the real problem was that the brand name was being cannibalized by a sister location in another city. Anyone searching the restaurant's name was finding the other location first. It had nine years of SEO equity, 1,200+ reviews, and thousands of followers. The new location was invisible to anyone who didn't already know to search by city name. No amount of Instagram content was going to fix that.
"The prior agency had been optimizing the wrong thing for months. Not because they were incompetent — because they stopped at the first plausible answer."
The discipline I've built into every engagement is to keep asking after the first answer appears. What else is true? What haven't we looked at? What would break this diagnosis if it were wrong? The research doesn't stop when you find something — it stops when you've found everything worth finding. That's a different stopping point.
It's slower. It's more uncomfortable. It occasionally means telling a client that the thing they've been investing in isn't the problem. But the alternative is delivering a polished answer to the wrong question — which is the most expensive outcome of all.
