I’ve been thinking a lot lately about a book called Range by David Epstein.
It starts with a story most of us in martial arts have heard told as inspiration: the Polgar sisters. A Hungarian psychologist named Laszlo Polgar homeschooled three daughters in chess from age four. Drilled them. Specialized them early. Two became grandmasters. One — Judit — became the greatest female chess player who ever lived.
The martial arts world loves this story. We love any story that validates early commitment, deliberate practice, and the long grind. We tell it to parents who ask whether their six-year-old is “too young to start.”
Here’s what Epstein found when he actually looked at the data across sports, science, creative careers, and business: the Polgar approach works in chess. In most everything else, it produces burnout, rigidity, and a ceiling the specialist can’t break through.
That should stop every martial arts school owner in their tracks — because the implications are bigger than we usually admit.
The Difference Between Kind and Wicked Environments
Epstein makes a distinction that I think is one of the most useful frameworks I’ve encountered in years.
A kind learning environment has stable rules, immediate feedback, and repeating patterns. Chess is the purest example. The board doesn’t change. The pieces don’t invent new rules. A player who logs ten thousand games will eventually encounter most of the patterns the game contains. Pattern recognition built through repetition translates directly to performance.
A wicked learning environment has delayed feedback, shifting rules, and patterns that don’t reliably transfer. Building a business is wicked. Coaching humans is wicked. Competing in a combat sport at high levels — where every opponent brings different timing, range, and psychology — is wicked.
Here’s the question I started asking myself: which environment is running a martial arts school?
Almost entirely wicked. The market shifts. Parent expectations evolve. Staff dynamics are unpredictable. What worked to retain students five years ago may be exactly wrong today. The school owner who built their entire mental model around what worked in 2015 and never updated it isn’t more experienced — they’re more confidently wrong.
Epstein cites research on doctors, financial analysts, and intelligence officers showing that narrow specialists often get worse with experience in wicked environments. They build elaborate mental models that feel comprehensive and turn out to be increasingly disconnected from reality. Years of experience produce more confident judgments without producing more accurate ones.
I’ve watched this happen to gym owners. Twenty years in the industry, and they’re more certain than ever — about marketing approaches that stopped working, retention strategies that made sense before smartphones, pricing models that don’t reflect what their market actually will bear. The certainty isn’t expertise. It’s calcification.
What Actually Produces Elite Performance in Complex Domains
The athletes who reached the top of their sports in most disciplines — outside of chess-like games and technical specialties — were overwhelmingly people who played multiple sports as children, specialized late, and often switched disciplines well into their teens.
Roger Federer played soccer, squash, basketball, badminton, table tennis, and handball before tennis became his singular focus. The kids who specialized in tennis at age six and drilled year-round for a decade mostly burned out, topped out at regional levels, or got injured.
The same pattern appeared in inventors (most patents: multiple unrelated fields before breakthrough work), comic book artists (longest careers: most different genres drawn), and Nobel laureates (dramatically more likely than peers to have serious amateur pursuits in painting, music, or writing).
The skill that differentiated elite performers in wicked domains was analogical thinking — the ability to recognize when a principle from one domain applies unexpectedly in another. That capacity develops from breadth, not depth in a single subject.
What This Means for Your Kids Program
I want to be careful here, because this isn’t an argument against teaching children martial arts. It’s an argument against a particular framing we sometimes use to sell it.
When we tell parents that starting at age five and training consistently through childhood will produce a black belt, a champion, or a disciplined adult — we are sometimes implicitly promising that this is a kind learning environment with reliable, transferable outcomes. The discipline built here goes directly into academic performance, leadership, and life skills.
Some of that is true. Discipline, goal-setting habits, physical confidence — these transfer. But the research suggests the transfer is messier and less predictable than we advertise. The kid who does three sports and explores multiple activities may develop broader cognitive flexibility than the kid who drills one thing year-round from age five.
What I’ve taken from this: the honest sell for youth martial arts is what it actually delivers reliably. A structured environment. A clear value system. Physical literacy. Social development. Community. Adults who care about your kid’s growth. The confidence that comes from learning to fall and get back up.
That’s a powerful offer. It doesn’t need to pretend to be chess.
What This Means for Your Adult Program
This is where I think the real opportunity sits for most academies.
The adults walking through your door who are new to martial arts — the 35-year-old who played soccer in high school, coached little league, ran a half marathon, spent two years trying CrossFit — are not at a disadvantage because they didn’t start at age eight. The research says they may actually bring something the early specialist lacks: a wider toolkit of mental models, more comfort with being a beginner, and the analogical thinking capacity to connect what they’re learning in your gym to every other domain they’ve navigated.
Epstein’s core finding: match quality matters more than head start.
The adult who finally finds a martial art that genuinely fits them — that connects to something real in their psychology and their body — will outperform the kid who was pushed into it at six and stuck with it on willpower alone. Every “wasted” year they spent exploring other activities was actually the search process that produced the match.
Your adult program messaging should lean into this. Stop selling adults on overcoming their late start. Start selling them on the advantage of arriving with life experience, physical history, and the self-awareness to actually commit to something that fits.
What This Means for How You Run Your School
The hardest application of this research is turning it on yourself.
If you’ve been running a school for ten or fifteen years in one market, working primarily with one demographic, using methods you learned from your instructor and refined over time — you are operating in exactly the conditions that produce confident, calcified expertise.
The owners I’ve watched build genuinely resilient schools share a pattern: they import frameworks from outside martial arts. They read about behavioral economics and apply it to enrollment conversations. They study how fitness boutiques build community and ask what transfers to their context. They learn from the restaurant industry about how physical space shapes customer experience. They treat their own school like a wicked environment that requires ongoing calibration — because it is one.
This is what range actually looks like in practice for school owners. Wide reading. Cross-industry curiosity. A willingness to say the model that worked for the first decade may need serious adjustment for the next one. Comfort with not knowing, followed by systematic experimentation.
The specialist who drilled one system in one market for twenty years and extrapolated to everywhere is the Polgar approach applied to a wicked domain. The results are predictable.
The Line That Stayed With Me
Epstein buries this almost as a throwaway, but it’s the sentence I keep coming back to:
Match quality matters more than head start.
For your students, for the parents deciding whether to enroll their kid, for the adult who thinks they started too late — the research says the question to ask is whether this is the right fit, not whether it’s the right time.
For you as a school owner, the parallel holds. The right mental model for your market matters more than the years you’ve logged running the wrong one.
The Polgar sisters were extraordinary. The lesson most people extracted from them was wrong.
Your job — in your program, your marketing, your own ongoing development as a leader — is to stay honest about which kind of environment you’re actually operating in, and train accordingly.
