The War of Attrition
Two animals contest a resource by displaying — posturing, escalating, waiting each other out. Neither fights; they just persist, and whoever is willing to last longer wins. The biologist John Maynard Smith, who founded evolutionary game theory, modeled this and called it the war of attrition. Its defining cruelty is in the structure: both contestants pay the full cost of however long the standoff ran, but only one gets the prize. It’s what economists call an all-pay auction — you pay your bid whether or not you win.
That structure shows up wherever the way to win is simply to outlast, and the cost of competing is sunk regardless of outcome. Two firms in a price war both bleed money for months; one eventually exits, but neither gets those months back. Two people locked in a stare of wills, a bidding war, a filibuster, a strike — the resource goes to whoever endures longest, and everyone pays for the enduring.
The military version gave the phrase its weight. Attrition warfare means winning not by maneuver or a decisive blow but by grinding the enemy’s men and materiel down faster than your own. The grimmest example is Verdun in 1916. The German commander Erich von Falkenhayn was said to have intended it not to capture ground but to “bleed France white” — to make the French pour their army into a meat grinder. (Handle this carefully: the famous “bleed white” memo survives only as Falkenhayn’s postwar account, no original has been found, and historians genuinely disagree about whether attrition was his real plan or a justification invented after it failed.) Either way Verdun became the symbol of attrition: ten months, hundreds of thousands dead on each side, the front barely moved.
The strategic lesson is mostly a warning, because the all-pay structure makes these contests traps. The rational thing is often not to enter at all, or to quit early — but two things conspire against quitting. The sunk-cost fallacy whispers that you’ve already paid so much you can’t stop now (exactly backwards: what’s spent is gone either way). And each side’s continued presence makes the other feel that just a little longer will break them. So both keep paying, past the point where the prize is worth it, because stopping means having paid for nothing.
The way to win one is usually to make your endurance credible up front — to convince the other side you’ll outlast them so they fold before the costs pile up, which links it to credible commitment. And the wiser move is often to recognize an attrition trap and refuse it, the way not playing can beat playing. When you find yourself in a contest where everyone pays and only persistence wins, the sharpest question isn’t “how do I outlast them?” It’s “should I be in this at all?”
