The Insider Advantage Is Really the Advantage of Being Known

In The Wall Street Journal, Matthew Bidwell challenges one of the most repeated pieces of career advice of the last two decades. In Maybe Job-Hopping Isn't the Smartest Career Move After All, he draws on more than 20 years of research to argue for what he calls the insider advantage: people who stay with an employer often do better on promotion, performance, pay and even happiness than people who keep moving.

The evidence he gathers is striking. In one study of nearly 60,000 workers in Finland, employees were almost six times as likely to earn a meaningful promotion by moving within their company as by changing companies. In another, 74% of top executives got their roles from inside the firm. And people who changed employers more often in their 20s and 30s were earning less by their mid-30s than those who moved less.

Bidwell is careful, and so am I. He isn't saying never leave. He says moving makes sense when you don't enjoy the work, feel underappreciated or can't see room to grow. But one sentence in his explanation deserves more attention than it gets.

What Stayers Really Have

Bidwell explains why outsiders struggle to move up: progression requires an employer to trust you with something harder than you have done before, and "new bosses know very little about you." That is the whole story in seven words.

The insider advantage isn't really about tenure. It is about being known. Your current employer has watched you handle a crisis, seen how you treat people and learned what you do better than anyone else. A new employer has a résumé and a few interviews. When Bidwell describes new hires taking two to three years to fully establish themselves, he is describing how long it takes for people to see who you are.

That reframing matters because it changes the advice. Staying put only pays off if the people around you actually know you. I explored this in Where You Work Matters Less Than Who Knows You There. Plenty of long-tenured professionals are known only for the job they were hired to do ten years ago. They have the tenure without the advantage, and they quietly wonder why the promotions go to someone else.

Being Known for the Right Things

Here is the trap on the other side. Some people stay and become typecast. Their colleagues know the version of them that showed up in year one, and every new opportunity is filtered through that old picture. They are visible, but not seen. It happens often to the most dependable people. They become the ones everyone relies on for the same thing, year after year, and no one thinks to ask what else they could do.

So the real question isn't whether to stay or go. It is whether the people who make decisions about your future know what you naturally solve for today, which may be quite different from what you solved for when you arrived. What you solve for evolves over a career. If no one around you has noticed the evolution, you are spending your insider advantage on an outdated version of yourself.

The same logic explains why insiders often make strong leaders. I wrote about a CEO who argued that an insider can be the better innovator in What Stays the Same and What Changes Is the First Question a Leader Should Answer. Insiders know what to protect and what to change because they have been known, and have known others, long enough to tell the difference.

What Professionals and Leaders Can Do Now

Internal promotion systems, with their clear criteria and consistent reviews, are a real asset. They give everyone a fair path. But a system can only promote what it can see, and seeing people is a leadership job.

For professionals who are staying: ask yourself whether your manager could describe what you do best today in one sentence. If not, tell them. Volunteer for the project that shows the newer version of you rather than the one everyone already knows.

For professionals who are moving: you can't skip the years it takes to be known, but you can shorten them. In your first 90 days, tell your new colleagues what problems you love to solve, then prove it in small ways. Don't wait for people to discover you.

For leaders: before your next promotion decision, ask whether you are choosing the person you know best or the person you have taken the time to know. Talent often leaves not because it was underpaid but because it was never truly seen. Bidwell's research is a reminder that the most valuable career asset doesn't show up on a résumé. It lives in the relationships where people understand who you are.

The advantage of staying belongs to people who are truly known, so make sure someone knows who you are becoming.
