What draws them together
Why the one who crosses boundaries and the one who connects are drawn to each other
The Polymath knows that they sometimes cannot keep their interest in any one field for long. So beside the Mediator, who gathers scattered things into one, they finally put their wide interests to good use.
The Mediator, in turn, hesitates before new things in order to keep the peace. Meeting someone who crosses many fields without hesitation, they come to know the world outside their familiar range.
What they are good at together
What widens because they are together
Their greatest strength is that widening and bringing together connect. When the Polymath brings what they have seen in many fields, the Mediator organizes it into results people can accept. Widening alone becomes scattered and bringing together alone becomes narrow, but when the two work together, they can create work that is broad and that people accept.
They are especially good at work that involves many people and many fields. When one brings in different points of view and the other resolves the conflicts between them, people who would easily go their own ways work together as one team.
The hidden paradox
The freedom and gentleness that attracted them slow the work down
A day comes when the Mediator, who fell for the Polymath's wide curiosity, wears out from its scatteredness, and the Polymath, who relied on the Mediator's gentle way of creating harmony, grows frustrated with its indecisiveness. The two later grow frustrated over the very point that first attracted them.
The Polymath cannot finish any one thing, and the Mediator keeps putting off uncomfortable decisions. The two stood out because they were flexible, but if they do not organize that flexibility, they finish nothing.
Where they disagree
When the one who widens and the one who brings together move at different speeds
Their most frequent conflict comes from differing speed and direction. The Polymath wants to keep starting new topics without end, and the Mediator wants to finish the current work peacefully. Someone who wants to start and someone who wants to finish often do not fit.
The deeper risk is that neither of them is good at finishing or at asserting themselves. When the Polymath takes on more out of curiosity and the Mediator keeps adjusting to avoid conflict, they end up with many things started, none finished, and no one making the uncomfortable decisions.
