For most of my career my intuition was my edge. Twenty years across Microsoft, Adobe, Salesforce, and four startups gave me a gut that was right more often than the room, and people paid me for that gut. Then, in the last two years, I noticed it was confidently steering me wrong. The only way to stay good at the job was to stop trusting the thing that had made me good at it.
Strip the mystique off and product intuition is a big library of patterns, compressed from experience, that fires fast when a new situation rhymes with an old one. It feels like wisdom. It's statistics run on the dataset of your past. Which means it's only as good as the match between the world that trained it and the world you're in now. When the world moves slowly, your patterns stay valid. When it stops moving slowly, your library quietly goes stale. And the dangerous part is that it doesn't feel stale. Confidence doesn't decay just because the world it was built on did.
Updating a gut takes lived reps, and the world now moves faster than you can accumulate them. I caught myself doing exactly this. A founder showed me a product idea and my gut fired a confident no, I've seen this fail. I was pattern-matching to failures from a world where that thing was expensive to build and hard to distribute. In the current world it was cheap to build and trivial to test, and my expensive-world intuition was about to talk me out of something obviously worth trying. My experience was the liability, not the asset. That's the trap of seniority right now.
The obvious correction is replace intuition with data. Not quite right. Dashboards describe the past too, and they can be just as stale. The real upgrade is replacing trusted intuition with cheap experiments. Use the gut for what it's good at, generating a sharp hypothesis fast, then refuse to act until you've tested it against a real customer outcome. When a prototype took six months you had to ship on judgment. Now testing costs an afternoon, so shipping on gut alone isn't prudence. It's laziness with a senior title.
Here's the discipline I use. When I feel certain, I treat the certainty as information about my training data, not about reality. I ask what world this confidence was built in and whether that world is still here. Then I build the cheapest test that could prove me wrong and actually try to. This week, find one decision you're about to make on instinct. Write down what your gut says and how certain you are, ask what world trained that certainty, and run the cheapest test that could prove it wrong before you act.
