I wish I could title this post “How Pacifism Wins at life” since it’d immediately make everything much easier (especially writing this post), but as most well-meaning kids swiftly learn on the playground - the world is not gentle. It’s always bothered me how impossible it is to negate the need for strength in life (whether physical, emotional, individual, or collective), especially considering how unevenly and unfairly that stat is usually distributed. What bothers me even more, however, is how many people I’ve seen gleefully misapply and overfit this fact, falsely concluding that since one cannot survive without strength, it is the only meaningful form of power in the world. I’m sure you’ve seen these people too. There is another side to this coin, however. One that I care deeply about, and that carries just as much weight and impact as anything mentioned above: if you ever want to get anywhere as a person, society, or species, either. you can’t afford to negate gentleness We’re gonna dive into game theory here, so if you’re new to/rusty on the terminology, the single best thing you can do is click for a brilliant interactive crash course on all the meaningful bits. If you’re short on time you’re better off prioritizing this click rather than reading the rest of this post (Nicky Case is amazing)! Quick note: here Many smartass variations of have been cooked up over the years, with each change in the parameters of the game bringing along with it a new balance of incentives, and different winning strategies accordingly. the prisoner’s dilemma Should you make like and always turn the other cheek, or should you play like Lucifer himself and ruthlessly exploit everyone you meet? Maybe you need a complex web of conditions defining how you act towards others based on your relationship so far, or maybe you can just do unto others as they do unto you. Jesus Every variation teaches us something new about the dynamics of selfishness and selflessness, trust and defection, all while generating a rich abundance of smug nerds to debate which ones apply best to which real-life situation. Debate is cool and all, but what I don’t understand is why all said nerds don’t just stop and yell out in unison: WE’VE ACTUALLY KINDA SOLVED IT! Because we actually kinda already have, and the result is beautiful. Let’s start with an overview of the most impactful conditions of any prisoner’s dilemma, and select the ones that reflect the environment of the real world best. We’re doing this to establish that whatever we end up discovering later on which can demonstrably, empirically, and objectively thrive under these conditions - must be the brilliant strategy best applied to the majority of real-life situations. mysterious strategy Let’s get to it: Most real-life situations (whether between people or nations) are not one-time events, but rather involve repeated interactions over time. With the exception of aggressive drunks outside pubs, we usually develop a long-term repertoire of past actions with one another. To clarify, even a single conversation can technically be defined as a “repeated interaction” (so long as each side gets more than 1 line of dialogue each)! Repeated/ - One-off Rounds We have imperfect information about each other's intentions, payoffs, and the consequences of our actions. Plenty of room for error. Imperfect/ - Perfect Information We can certainly communicate with one another, whether explicitly or implicitly. Misunderstandings, bluffs and lies are completely possible, but are forms of communication nonetheless. Communication: On/ - Off The cost/reward for defection/co-operation vary greatly between contexts. This is likely the highest variance condition here. Asymmetric/ - Symmetric Payoffs Groups can grow, shrink, merge and split depending on the actions of their members. Furthermore, interactions can be between, and affect, multiple participants at once. Variable/ - Constant Group Size Anger, fear, empathy, can all affect decision making. That’s not even mentioning cognitive biases (#UncleKahneman). Emotionality: On/ - Off Nobody knows anything about anything or anyone for sure and we’re all terrified mortal coils. The technical term for this is and . Uncertainty: So On It Hurts/ - Off Environmental Uncertainty Social Uncertainty Right! This should be a sturdy enough foundation (let me know if I’ve missed anything important in the comments). The stage is set, and you’re now ready to hear about one of the most illuminating experiments done in the field of game theory, but in a shortened tl;dr manner. This is mainly because I suspect a significant portion of you have already heard some version of this before, and that the other, equally significant portion of you that hasn’t, would enjoy it being covered while favouring promptness. To the remaining, probably much tinier portion of you (yet still equally significant!) that would actually love to read a full breakdown - I can only humbly ask for your forgiveness and direct you . Quick note: here The gist is this: in the 60s, a super influential game theory researcher (named Axelrod) invites other super influential game theory researchers from around the world to devise their ultimate prisoner’s dilemma strategy, code it, and then let the resulting programs fight each other to the death in a grand digital petri dish. The tournament is kinda like a turn-based RPG (with depleting hit points and everything), except that at the end of each fight, whichever program wins gets to survive and reproduce (just like in biology)! Whoever spawns enough offspring to eventually take over the board is the winning strategy. Thousands of lines of code riddled with complexity were submitted, ranging from the most ruthless of programs to the kindest. They were then all promptly fired up and sicced at each other for 200 rounds. Soon enough one winner stood supreme, and it was poetically too good to be true too, since it was only two humble lines of code: Rule 1 - Be nice (technically meaning always co-operate on the first round).

Rule 2 - From then on just copy what the other player did in the previous round (meaning an eye for an eye and a hug for a hug). What a tear-jerking win for ancient wisdom! Literally, every major religion has described its own variation of a “do unto others as they do unto you” principle at some point or another, crystallizing a timeless insight out of pure intuition and an astute observation of life’s dynamics. In this case, the strategy was simply called Tit for Tat. It’s a wise strategy, and fully compatible with life’s continuous demand for strength as a deterrent, plus it also manages to incorporate an impressive dose of goodwill. The conclusion is super simple too: you should always attempt to come in peace, bravely placing your trust in others at risk of getting hurt. However, should they try to harm you, don’t hesitate to retaliate back and teach them a lesson. Sounds good, but NOT GOOD ENOUGH!!! As I’m sure you’ve noticed, the conditions of the experiment above don’t quite satisfy the requirements we initially established as necessary to make its conclusion fully applicable to real life (and besides, I still owe you an Adjective). Let’s quickly review the criteria one by one and see where we stand: : - There were 200 of them! Repeated Rounds TRUE : - Programs didn’t know the strategy of their opponents ahead of time. Imperfect Information TRUE : - The programs couldn’t chit-chat or gossip. Communication On FALSE - The cost/reward matrix for co-operate/defect was symmetrical and constant. Asymmetric Payoffs: FALSE - While programs technically fought 1v1, the outcome of each fight affected the overall group representation of each program on the board. Each win increased the probability that a program will meet a like-minded partner and directly influenced the viability of its strategy. Variable Group Size: TRUE - The programs never got to learn about love. Emotionality On: FALSE While the programs certainly suffered from , not knowing how their adversary would react, they did enjoy the very important luxury of , with perfect reliability for inputs and outputs, and no risk of earthquakes. Uncertainty On: HALF TRUE - Social Uncertainty Environmental Certainty It seems we're missing , , and . Close but no cigar. Communication Emotionality Environmental Uncertainty, Asymmetric Payoffs Briefly setting aside Asymmetric Payoffs (don’t worry, they’ll come back soon), what I’m hoping you’ll notice is that the remaining three conditions are all different manifestations of the same messy, real-world principle: sometimes, things can go horribly wrong by complete accident. More specifically, there’s always the potential for Miscommunication, Miscalculation, Mistake, and Mishap. In a world full of Tit for Tats, any of these can lead to a catastrophic cycle. Ominous Ms Say two Tit for Tats run into each other in real life. Both are immediately nice to one another and begin to reciprocate said niceness ad infinum. is within reach. However, throughout the entirety of their relationship, all it would take is one tiny error, one tragic misplaced M by either one, to immediately initiate an ever-escalating cycle of mutual retaliation until one or both drop dead. Utopia In practice, Tit for Tat can actually be a pretty disastrous strategy, since it can easily get you deadlocked in a costly conflict. Whether its a war that’s fought until there’s no one left to fight, two political rivals forced to dedicate an ever-increasing segment of their campaign budget to disparaging one another’s public image, or simply a battle of pettiness between middle management and employees - in the real world, you can’t ignore the need for some form of de-escalation mechanism. Even if it’s costly, you find a way to cut terrible feedback loops. You need one additional power: Get a load of this: must GENTLENESS! So long as you possess the strength to defend yourself, you can always make the choice to generously give someone the benefit of the doubt, relinquish a justified retaliatory response, or most gently of all, simply decide to forgive. Why? All for the sake of valiantly fighting to keep the option for peace and collaboration open at all times, lest it get closed off forever to everyone’s mutual detriment. I can’t think of a more heroic struggle. Being generously gentle means you’re prepared to get hurt in the name of peace, and it’s an incredibly brave and risky thing to do. How risky? Asymmetrically so! (I told you they’d be back) are all around us, since in real life no two players ever engage on equal footing. Each player has a different ratio between how much they want something, what it’d cost them to get it, and what capabilities are at their disposal. The risk/reward matrix is always dynamic and far from symmetric between players. Asymmetric Payoffs The defining variable here, unfortunately, is strength (we knew it was inescapable from the get-go). This certainly complicates the decision-making calculus, but it certainly doesn’t negate the role of gentleness! Luckily, in real life, the asymmetry goes both ways: Even when facing a “stronger” player, who says you have to engage with asymmetric strength symmetrically? There are many kinds of rewards, and one form of strength can be completely negated by another (think of the difference between Tank vs Tank and Tank vs RPG). Furthermore, since : , outcomes are always unpredictable for sides - each one could potentially outmaneuver, attrition, shift vectors, or just plain luck out vs the other, regardless of the perceived reward matrix. Uncertainty On both Asymmetric Payoffs are merely a complicating factor, but the key principle still stands: In the long run, the cost incurred each time you attempt to cooperate and get exploited usually pales in comparison of the cost of never trying at all. With our newly acquired wisdom, let’s return to the original Tit for Tat strategy, and custom fit it with a mechanism for self-correction. We just need to add one rule: Rule 1 - Be nice (technically meaning always co-operate on the first round).

Rule 2 - From then on just copy what the other player did in the previous round (meaning an eye for an eye and a hug for a hug).

Rule 3 - After you retaliate, always try to co-operate again in the next round. Congratulations! (coined by Axelrod himself)! It maintains the key benefits of regular Tit for Tat, while possessing the ability to break out of cycles should they arise. We’ve also finally come full circle to the title of this post! It’s been emotional. We’ve just created “Generous Tit for Tat” Ominous M This strategy can be dangerous, counter-intuitive, and painful, that’s why it requires such a unique kind of boldness - but the fact of the matter is, it’s one of the strongest strategies for winning at life in the long term. Whether between individuals/communities/corporations/nations. It’s gonna be tough, but never forget: if you don’t go around actively trying to exploit others, are strong enough to protect yourself when others do, and have the discipline within you to remain gentle and forgiving despite it all - you’ve already done humanity an incredible service by just you being you. Wear whatever scars you collect on your journey with pride! The End! If you enjoyed our little adventure, you’re super invited to join the next one! Also published here.
