A résumé sits on a recruiter's screen, eleven lines long, nine employers in twelve years. Handwritten in the margin, someone has penciled a single question mark. The résumé belongs to Obinna Farrell, thirty-one, who spent the previous decade doing stints in logistics coordination, secondary school tutoring, copywriting for a hardware startup, and something called "field operations" that he still struggles to explain at dinner parties. The question mark is not a verdict. It is, it turns out, a failure of the form.
The assumption baked into that question mark is that a career is a ladder and deviation is a fall. What the research on expertise actually shows is almost the opposite. In most fields — not surgery, not concert-level violin, but most fields — early specialization narrows the very range of analogical thinking that complex problem-solving requires. The person who has held five roles in ten years is not demonstrating instability. They are accumulating a kind of cross-domain fluency that a single deep track rarely produces. The cognitive tools from each role don't disappear when you leave the job. They migrate.
David Epstein documented this pattern at length in Range, drawing on researchers who studied experts across science, business, and creative fields. The finding that keeps reappearing is that late specializers. People who sampled broadly before committing. Outperformed early specializers over full careers in nearly every domain where the rules weren't fixed and predictable. Chess and golf rewarded early focus. Medicine, engineering, and entrepreneurship rewarded range. The distinction matters because most people assume their field is more like golf than it actually is.
So the moment to apply this is not a future choice. It's the review you're doing now, in the quiet after something has already been decided. The role you left after eighteen months, the sideways move that felt like defeat, the year you spent in a different industry before drifting back. Before you write it off, look for what crossed over. The logistics stint trained systematic thinking under deadline. The tutoring built the ability to diagnose where comprehension breaks down. Obinna Farrell's question mark deserves an answer, and the answer is in the margin of a different document. The one that lists what he can actually do.
A résumé is a record of where you were, not an account of what you absorbed. The question mark belongs on the assumption, not the path.
