Game Theory · GT-04
Is the pie fixed, or can the two of you actually bake a bigger one?
In a zero-sum game, one player's gain is exactly another's loss, so total value is fixed no matter what happens. In a non-zero-sum (positive-sum) game, cooperation can expand the total pie, so both sides can gain at the same time.
Formalized in John von Neumann and Oskar Morgenstern's 1944 book Theory of Games and Economic Behavior, which built much of classical game theory around the zero-sum case before extending it.
The Mechanism
Same negotiation, two different pie sizes — toggle it
The size of the pie is itself a variable — before splitting anything, check whether trade, timing, or creative deal terms can grow the total available value. Treating an expandable negotiation as fixed-pie leaves real value on the table for both sides.
01 · MOST NEGOTIATIONS AREN'T POKER
Sports and poker are genuinely zero-sum — most business isn't
In poker, one player's winnings are literally drawn from the other players' stacks — the total at the table never changes. Most real economic exchange (a job offer, a supplier contract, a partnership) is not like this: both parties can walk away with more value than either started with, because trade itself creates value neither side had alone.
02 · THE FIXED-PIE BIAS
People default to treating negotiations as zero-sum even when they aren't
Decades of negotiation research (notably Bazerman and Neale's work from the 1980s–90s) documents a persistent cognitive bias: negotiators assume their counterpart's interests are perfectly opposed to their own, and miss trades that would make both sides better off — for instance, one side caring more about price and the other more about timeline, which allows a mutually beneficial trade neither noticed.
03 · IDENTIFYING WHICH GAME YOU'RE ACTUALLY IN
The diagnostic question
Ask directly: is there any lever here — financing terms, timing, scope, bundling, information sharing — that could grow the total value on the table, or is the total genuinely fixed regardless of what either side does? Sports outcomes and fixed-supply auctions are usually the latter; most negotiations and partnerships are the former.
Where It Fails / Inversion
Where it fails / inversion
Treating a genuinely zero-sum situation as if it were positive-sum is its own costly mistake — pursuing "win-win" framing in a competition for a single scarce resource (one open board seat, a fixed number of playoff spots) can lead to naive concessions that only help your opponent, since there is no larger pie to actually create. The skill isn't defaulting to either frame; it's correctly diagnosing which one you're in before you negotiate.
How To Use It
Worked example · a supplier renegotiation
A retailer wants a lower unit price from its supplier; the supplier resists because margin is thin. Treated as zero-sum, this is a pure standoff over one number. Reframed as positive-sum: the retailer can offer a longer contract term (giving the supplier planning certainty and lower customer-acquisition cost), and the supplier can offer volume-based rebates instead of a flat price cut (protecting margin on the base case while rewarding growth). Both walk away with more than either initial fixed-pie position offered.
The renegotiation didn't succeed by "being nicer" — it succeeded by finding dimensions of the deal beyond the single number both sides were initially fighting over.
How to use it
Before your next negotiation, explicitly list every dimension of the deal beyond the headline number (timeline, volume, exclusivity, risk allocation, information sharing). Each one is a candidate lever for turning a fixed-pie standoff into a larger, genuinely shared pie.
