The Expert Trap: When Success Makes You Stop Asking Questions

I came across this Henry Ford quote and couldn't stop thinking about it.

“None of our men are 'experts.' We have most unfortunately found it necessary to get rid of a man as soon as he thinks himself an expert because no one ever considers himself expert if he really knows his job.”
— Henry Ford, My Life and Work (1922)

Ford’s point was the second someone believes they've mastered something, they stop looking for what's still not working.

I love that perspective. So I was surprised, when I dug into it, that Ford actually failed to apply it to himself and his strategic thinking.

He wrote that line in 1922. Just a year later, Alfred Sloan took over at General Motors and began building separate cars for every income level, with Chevrolet at the entry level pricing and Cadillac at the luxury tier. Ford kept stubbornly selling one car in one color, which to be fair, had been a wildly successful strategy to date. But by 1931, GM had passed Ford in sales.

Ford kept applying his rule inside his factories all through the 1920s, pushing for better and more innovative manufacturing on the Model T year after year. But in 1926, with Model T sales falling, Ford's vice president Ernest Kanzler sent him a memo arguing for a replacement car. Ford's response was to say that Kanzler was "getting too big for his britches," and he fired him soon after.

Ford had been extremely successful with his original concept, so when Kanzler's memo threatened it, he protected his record and got rid of Kanzler instead.

Past proof replaced present curiosity.

That's what makes the expert trap so dangerous. The more success you've had, the more evidence you have that your judgment is good. Logical, right? Experience becomes expertise. Expertise becomes confidence. And eventually, that confidence can make contradictory information easier to dismiss.

You can see versions of this everywhere. There’s the company applying last decade's assumptions about how customers discover products to a world increasingly using AI. Or the leadership team still using the planning process that helped build the company when it was half its current size. And don’t forget the executive dismissing someone's challenge because “we’ve tried that before and it didn’t work.”

Sometimes it's much smaller than that. It's the meeting where someone challenges an assumption you've held for years and you immediately start explaining why they're wrong. (Ugh. I cringe thinking about the times I've done this.) But really, that's probably the moment to get curious.

It takes what I call confident humility. You have to balance being certain enough to lead while staying open enough to keep learning. I’m not suggesting you have to constantly second-guess yourself. You still have to make decisions and lead with conviction. But I am suggesting you have to commit strongly enough to execute your decisions while staying curious enough to recognize when the evidence changes..

Ford preached it, but he missed it in the mirror.

That mindset matters all the way through execution. You need it when you're writing the strategy, when people challenge it, when you're communicating it, and especially when the results start telling you something you didn't expect.

Where are you relying on a past win instead of re-examining it?

One simple question that can help is to ask yourself, “If I were looking at this situation for the first time today, knowing what I know now, would I still make the same decision?”

Pay particular attention to the ideas you're most certain about. That's where being right in the past can make new information feel like a threat.
