Leonardo da Vinci painted, engineered, studied anatomy, designed machines and investigated optics. Benjamin Franklin moved between printing, politics, electricity, diplomacy and invention. We remember such people as polymaths: people whose serious interests and abilities extend across several different fields.
Yet the interesting thing about a polymath is not simply that they know a lot of things.
A pub-quiz champion knows a lot of things.
Polymathy becomes valuable when knowledge from one field starts changing the way a person thinks about another.
A psychologist notices something about pricing. An engineer sees a problem in the company's management structure. A photographer understands why customers keep overlooking a product. Someone interested in biology recognises that a supposedly efficient organisation has removed the redundancy that once made it resilient.
The knowledge crosses boundaries.
That may make polymaths particularly valuable in business.
Breadth alone doesn't make a polymath
Researchers Robert and Michele Root-Bernstein define polymathy in terms of active engagement with multiple pursuits, either at the same time or at different stages of life.
Crucially, this involves more than dabbling. Breadth combines with depth and, eventually, integration.
Their studies of Nobel laureates suggest that unusually successful scientists frequently maintain substantial interests outside their formal speciality. Earlier work also found that eminent scientists were more likely than comparison groups to engage seriously in art, music, crafts and other creative activities. More recent research suggests that Nobel laureates themselves frequently describe these apparently unrelated interests as part of the way they think and create.
This requires an important qualification. Such studies show an association. They do not prove that learning the violin will win you a Nobel Prize.
Nevertheless, they challenge the assumption that serious achievement always requires progressively narrower specialisation.
The polymath seems to do something different.
They collect ways of thinking.
One problem, several models
Imagine a business suddenly starts losing customers.
The marketing specialist studies advertising.
The accountant looks at price.
The sales director examines the sales team.
The technical director examines the product.
The operations manager studies delivery.
Each may find something useful. Each may also become trapped by the boundaries of their own expertise.
The polymath asks a slightly different question:
What if several of these things interact?
Perhaps a product alteration made the service slightly harder to use. This increased support calls. Longer support times then irritated customers. Irritated customers became more price-sensitive. Marketing responded by offering discounts, attracting a different type of customer and increasing support demand still further.
Suddenly there is no single problem.
There is a system.
This is one reason wide-ranging thinkers can appear frustratingly unwilling to give immediate answers. Before answering the question, they may want to know whether everyone is asking the right question.
Research on expert judgement offers an interesting parallel. Philip Tetlock famously distinguished between intellectual “hedgehogs”, who interpret events through one dominant idea, and “foxes”, who draw upon several ideas and tolerate contradictions. In his forecasting research, fox-like thinkers tended, under many conditions, to make better predictions. A fox is not necessarily a polymath, but the intellectual resemblance is striking.
The polymath is usually carrying more than one map.
They can become beginners again
There is another, less obvious characteristic.
Polymaths repeatedly permit themselves to look foolish.
An accomplished lawyer learning programming suddenly becomes a novice. A successful engineer studying painting may discover that a sixteen-year-old art student can see something she cannot. An economist learning psychology encounters an entirely different language for describing human behaviour.
That experience can become uncomfortable once someone has built an identity around expertise.
Expertise gives status.
Beginnerhood takes some of it away.
Yet the capacity to return voluntarily to beginner status may protect the polymath from one of the great dangers of professional life: confusing what I know with what can be known.
The more experienced we become, the easier it becomes to interpret unfamiliar problems using familiar tools.
To a person carrying only a hammer, the old saying goes, everything starts resembling a nail.
The polymath keeps visiting the hardware shop.
They often find the question before finding the answer
Businesses naturally reward answers.
How do we increase sales?
How do we reduce costs?
How do we recruit better people?
How do we get more website traffic?
Yet a good polymath can become irritating at precisely this moment.
They may ask:
Why do we need more traffic?
What happens to people who already visit?
Why are existing customers leaving?
Which costs produce value?
What exactly do our best employees do differently?
What would happen if we stopped selling this product altogether?
These questions can initially sound obstructive because they interrupt the rush towards action.
But solving the wrong problem efficiently remains a poor use of resources.
Different disciplines teach different kinds of questioning. Science asks how a claim could be tested. Mathematics demands precision. Psychology asks how people actually behave. Economics looks at incentives. History asks what happened last time. Design asks how something feels to the person using it. Systems thinking asks what happens next.
Combine these habits inside one person and the question itself can become an object of investigation.
That can save a company an enormous amount of money.
They recognise patterns rather than merely collecting facts
At first, learning a subject means remembering many separate things.
With experience, those things begin clustering into principles.
Feedback.
Incentives.
Bottlenecks.
Selection effects.
Adaptation.
Signalling.
Trust.
Network effects.
Unintended consequences.
A polymath begins finding these same structures in apparently unrelated places.
A lesson about evolutionary biology may illuminate competition between products. A principle from behavioural science may explain why a technically superior service fails. A concept from family systems theory may suddenly make sense of an executive team locked into repetitive conflict.
The details change.
The underlying shape sometimes does not.
This ability to move knowledge across boundaries resembles what organisational researchers call boundary spanning. Modern innovation frequently requires information to cross departments, professions and organisations rather than remaining inside specialist silos. Research on innovation therefore increasingly treats knowledge integration across boundaries as a significant organisational capability.
A polymath can sometimes perform that integration inside one head.
They are harder to capture with a single story
There is another useful commercial advantage.
Polymaths tend to encounter competing explanations.
A person who understands advertising knows about framing.
Someone who understands statistics asks about the sample.
A historian asks what has been omitted.
An economist asks who benefits.
A psychologist asks what emotional need the story satisfies.
A technologist asks what the system actually records.
Consequently, a confident statement such as “customers want this” may trigger questions.
Which customers?
How many?
How do we know?
What did we ask them?
What did they actually do?
Does someone benefit from interpreting the evidence this way?
This does not make the polymath automatically sceptical.
Automatic disbelief is merely belief facing backwards.
The valuable habit involves examining several explanations before settling on one.
The great strength can also become the great weakness
Here we encounter the problem businesses need to understand.
The same mind that makes connections can become distracted by connections.
One question produces another.
A conversation about improving the website becomes an investigation of artificial intelligence, which suggests a change to the sales process, which raises an interesting question about behavioural economics, which reminds the polymath of something they once read about signalling theory.
Two hours later everyone has learned something fascinating.
The website remains unchanged.
This is where the romantic description of polymathy needs correcting.
Curiosity has a cost.
Businesses eventually have to ship the product, complete the refit, send the invoice, publish the website or close the sale.
The organisation scholar James March described a related tension as exploration versus exploitation. Organisations need exploration: experimentation, discovery and new possibilities. They also need exploitation: refinement, execution and making proper use of what they already know. Too much exploitation can make an organisation rigid. Too much exploration can leave it permanently experimenting without harvesting the results.
The same tension can exist inside a polymath.
Their greatest gift may be exploration.
Their greatest difficulty may be knowing when to stop exploring.
So how do you manage one?
Trying to remove a polymath's curiosity probably defeats the purpose of employing them.
A better strategy gives curiosity boundaries without extinguishing it.
Give them a real problem rather than a tightly prescribed method.
Define what success looks like.
Set a point at which investigation turns into decision.
Pair them, where appropriate, with people who enjoy completion, detail and repetition.
Allow some intellectual freedom around the edges of the core task.
And periodically give them genuinely difficult problems.
This last point matters.
Research on organisational creativity has repeatedly highlighted intrinsic motivation: people tend to produce their most creative work when the problem itself feels interesting, challenging or satisfying. Management and the surrounding work environment can either support or suppress this.
A highly curious employee asked to repeat the same narrowly defined task indefinitely may eventually disengage, manufacture novelty, or leave.
The management problem therefore becomes rather subtle:
How do you preserve breadth while achieving focus?
One answer is to separate the destination from the route.
Tell the polymath what must reach harbour and by when.
Give them some freedom in deciding how to sail there.
Every company needs at least one
Most people are not polymaths.
Nor should they try to become one.
Civilisation depends upon specialists. You probably want the surgeon operating on your heart to possess extraordinary depth in cardiac surgery rather than an enthusiastic side interest in twelve unrelated subjects.
Businesses need specialists for exactly the same reason.
But businesses face another class of problem.
They must decide which problem matters.
They must recognise changes occurring outside their own industry.
They must notice connections between customers, technology, economics, psychology, regulation, design and culture.
They must occasionally recognise that an apparently sensible specialist solution is making the wider system worse.
For these tasks, specialisation alone can become dangerous.
Scott Page's work on problem-solving diversity provides a useful clue. Different perspectives and different problem-solving tools can, under suitable conditions, make a group more capable than a collection of people approaching a problem in essentially the same way.
A polymath represents a particularly interesting version of this principle.
They bring cognitive diversity with them.
This leads to a practical conclusion.
Every business, whatever its size, should employ at least one polymath.
In a large corporation that person may sit across strategy, innovation, product or the chief executive's office. In a small company they may hold an ordinary operational title while quietly becoming the person everyone consults when a problem crosses boundaries. In a very small business, the role might amount to a part-time employee or retained adviser whose value comes precisely from seeing beyond the immediate trade.
Their job is not to know everything.
Their job is to notice what everyone else has forgotten to look at.
And therein lies the management challenge.
Give a polymath unlimited freedom and they may wander endlessly among interesting possibilities.
Force them into a narrow intellectual box and you may destroy the very capability you employed them for.
The trick is neither freedom nor control.
It is stimulated focus.
Give them a difficult destination, a meaningful deadline, enough freedom to explore several routes — and a reason to keep bringing the ship back towards harbour.
That combination may turn an easily distracted polymath into one of the most valuable people in the business.
