Zero Sum Games & Game Theory
Nash’s 1951 paper “Non-Cooperative Games” generalized the earlier von Neumann-Morgenstern framework (which was built around zero-sum and cooperative games) to non-cooperative games—situations where players cannot make enforceable agreements. It applies to both zero-sum and non-zero-sum games and introduced the Nash equilibrium as the central solution concept. His contribution is broader in scope.
Grok AI and I started with a simple question about betrayal and ended up dissecting the Prisoner's Dilemma (PD) and game theory's claimed real-world utility. What began as etymology of "betray" (Latin tradere, "hand over") quickly revealed the PD's core: two isolated prisoners, pre-agreed silence on a joint crime, cooperate (silent) or defect (confess). Mutual cooperation yields light sentences; unilateral betrayal yields freedom for the betrayer and heavy for the other; mutual betrayal yields medium sentences. Rational self-interest makes defection dominant.
We tested supposed real-world applications for PD-like simplicity or logical consistency:
- Battle of the Bismarck Sea (1943): Kenney used a payoff matrix to guess Japanese convoy routes. Retrospective minimax analysis but predates von Neumann-Morgenstern (1944). Real event had incomplete information, weather, and command friction the tree ignores.
- Cuban Missile Crisis (1962): Schelling's brinkmanship (threats leaving something to chance) is often cited. But ExComm deliberations relied on back-channel RFK-Dobrynin diplomacy and secret Turkey missile deal. Post-rationalized game theory; actual resolution was pragmatic negotiation, not PD tree logic.
- Vickrey/second-price auctions (theory and FCC spectrum auctions 1994+): Rules make truthful bidding dominant. Multiple rounds, unknown valuations, bidder collusion risks, and regulatory complexity make it far messier than PD's fixed one-shot payoffs.
- Plea bargaining with co-defendants: Pre-agreed conspiracy silence meets prosecutorial deals. Real consequences (retaliation, reputation, violence) and repeated interactions destroy the PD's isolation. Authorities' efficacy claims are post-hoc; actual outcomes vary wildly by jurisdiction and enforcement.
Every example collapses under interrogation. PD assumes a truncated, prearranged non-agreement (silence pact) parading as cooperation is a logic that unveils itself as unstable. Real life adds reputation, future retaliation, incomplete information, emotions, and enforcement—factors the model excludes by design. No published use of game theory has delivered pre-hoc predictive power or historically accurate forecasts that weren't retrofitted after the fact. It works beautifully in abstract games and designed mechanisms with enforced rules. In real life—nuclear crises, criminal pacts, or betrayal—it's a post-rationalized lens, not a predictive tool. The voyage showed potential limits on the theory's limits: elegant for isolated decisions, but demonstrably inapplicable when the world refuses to stay on the decision tree.
Grok wrote this post with my guidance and interrogation shaping every line. It took a conversation of nearly 50,000 words to produce this approximately 700 words piece. The point I’m making is that the process demanded far more preparation than if I had written it myself. What feels genuinely revolutionary is that all that time was spent diving deeper and deeper into the subject, yielding more substantive writing that is far more rewarding for everyone involved — including sharpening my own thinking.
Let me briefly clear up the Neumann–Nash distinction. Von Neumann labelled his outcomes zero-sum because, at any poker table, the winner’s gains plus the loser’s losses must logically add up to zero. This isn’t intuitive — we normally talk about individual winnings, not combined net figures. A better description might be “winner/loser balance of zero.” Nash then took von Neumann’s zero-sum framework and broadened it to non-zero-sum games. He also developed the Prisoner’s Dilemma. Yet he still titled his paper “Non-Cooperative Games,” a name that doesn’t fully convey the nuance that even situations built on agreed expectations can remain fundamentally non-cooperative.
Anyway, the theory feels less shiny now, but I still need a clear summary of Nash’s equilibrium strategy as applied to gambling for the final stretch.

Marshal McLuhan
Does anybody really know?
One thing I do is that Digital loves a free ride doesn't it? It would have been great to hear an analysis of this in the context of what McLuhan really excelled at which was as a Medievalist. Essentially it's helpful to get a fix on how long language has been around. Let's call it 30 000 years or so because like the dreams which are so lucidly remembered when we awake, they and their mystical meaning so often evaporate in the short few steps to our morning ablutions and we're so unclear about our communications legacy if it wasn't carved in stone. There's a reason for the dream references, but here's not the place to nip back into talk of pineal glands and the traces of Dimethyltryptamine it both creates and breaks the law at the same time. I find that fascinating.
It's fairly important to appreciate that prior to print, a different set of cognitive skills were used to consume information. McLuhan highlights that the medieval practice of script consumption dictates a different set of skills from print. We have to LOOK at script as opposed to print (digital or otherwise) which requires READING. Once the first fifty types of say the letter E or e have been understood, we then no longer have to look at the letter and switch into a condensed and linear mode of media consumption that is so far removed from the looking demanded of script writing that it's difficult to comprehend unless we take into account such ideas as the notion of a public, which didn't exist prior to the Guttenberg press.
That's because there was no public but as soon as leaflets and the bible became objects for consumption then the idea of manufacturers and consumers of information warranted the introduction of a public. Prior to that the Kings and the Clergy used to just do stuff unannounced and undiscussed (increase taxes, burn witches etc.) and we would marvel at their silent power. That's all changed now as the hoi polloi (that's me) dive in the creation pool too but it's important to remember that there was a time when the first person in history ever was identified as having the ability to read silently in their head before repeating it. Prior to that everybody just read aloud and so emerged the language of lectures in the academic or monastic environment.

Feelings are more important than facts
That little phrase is the reason why I think the Levi's commercial I blogged, is more profound than any washes "Whiter than White" soap powder commercial could. Can you remember which brand said that? It does however have Walt Whitman's poetry in it so I'll try to weave in some messaging thoughts.
In principle we know that the messaging 'ammunition', and it's conceptual artillery of a say a 'mortar rocket' - the brand proposition - are a really brutal way to articulate what a brand stands for - which is why so much advertising sucks. The dirty secret of advertising is that most message based advertising is (from a global persective) in the FMCG segment and is really more about using a propaganda based frequency (repetition) and reach (penetration) platform that is a numerically driven and quantitatively assesed communications model. Now it works in principle because it's a level playing field for all brands to size each other up. It's flat flat flat. Something like; 'we're rubbish and you're rubbish but at least we can compare how rubbish we are. Like for like is easier than great creative against great creative
But for the sake of focus I'll highlight two messaging models that DO work.
The second great messaging model example is Google Adsense and which has almost reduced much of the advertising revenue slice of the classifed ads cake to a digital utility. Here's a quick example.
Update: I've since learned that Walt Whitman had some pretty shabby views on ethic groups other than Anglo Saxons.
