Fooled by Randomness

Meet Nero Tulip, a man who discovered his passion for trading after a bizarre incident at the Chicago Mercantile Exchange. He plunged into the world of trading, finding it far more exciting than the academic world he originally hailed from. He became a trader not for the wealth, but for the thrill of the game, finding solace in the unpredictability of the market. 

Nero was a unique trader, risk-averse, and focused on long-term sustainability rather than short-term gains. He lived comfortably, indulging in intellectual pursuits, and teaching a seminar on the History of Probabilistic Thinking at New York University. 

Then there was John, Nero’s wealthy neighbor, who was a high-yield trader. John was flashy, flamboyant, and seemed to be doing far better than Nero. John's ostentatious lifestyle began to gnaw at Nero, making him question his own decisions and successes. However, Nero knew that John was taking risks he himself would never take, and was certain that one day John's luck would run out.

Sure enough, in September 1998, John was fired and lost almost everything he had, a fate Nero had always avoided due to his cautious trading strategy. Despite feeling a pang of Schadenfreude, Nero felt vindicated, knowing that his cautious approach to trading had saved him from the same downfall.

The story of Nero and John highlights the role of serotonin, a neurotransmitter associated with feelings of well-being and happiness, in influencing our behaviors and perceptions of success.

Could a Cautious Trading Strategy Save You from Financial Downfall?

The concept of alternative histories, or possible courses of events that could have unfolded, plays a crucial role in understanding randomness and decision-making. Often, we judge a decision's quality based on its outcome, but this view is flawed. 

For instance, imagine a game of Russian roulette where you could win $10 million. Let's say, five out of six possible outcomes lead to fortune, while one leads to death. Society tends to celebrate the winner without considering the inherent risk of the game. 

This false understanding of success is common, especially in fields like politics, medicine, and investments. It's crucial to remember that a good decision does not always lead to a good outcome and vice versa. This is because our world is deeply entwined with randomness, and often, the results we experience are due to chance rather than skill or wisdom. 

This is not to undermine the role of knowledge, skill, or hard work. However, it's essential to recognize that sometimes, we're just lucky. We must also remember that every success story has a hidden graveyard of failures that followed the same strategy but weren't as fortunate. For instance, Alexander the Great and Julius Caesar are known because they won, but countless others with similar qualities have been lost to history because they lost. 

In the world of finance, risk managers aim to prevent institutions from playing Russian roulette. However, their role is often more about creating an illusion of control rather than actual risk reduction. They can't fully control or predict the randomness inherent in financial markets. 

Russian Roulette Decisions: Understanding the Role of Randomness in Success and Failure

Our minds are wired to seek patterns, to create meaning from the randomness of life. This is a survival mechanism, honed over millennia. But in our complex, modern world, this instinct can lead us astray. 

We see patterns where none exist. We ascribe meaning to random events. We neglect the role of chance and coincidence in our lives. And this can have serious consequences, especially in the world of finance and trading.

Consider the story of a retired dentist-turned-trader, who closely monitors his portfolio's performance every day. Over the course of a year, he can expect a 93% success rate. But if he were to check his portfolio every second, his success rate drops to 50%. This is because over short time intervals, one observes the volatility of the portfolio, not the returns. 

Yet despite knowing this, the trader still feels a pang of pain with every loss and a surge of joy with every gain. This emotional rollercoaster can lead to burnout and poor decision-making.

The same principle applies to news consumption. The constant stream of news updates and "breaking news" alerts can feel overwhelming and lead to a distorted view of the world. Much of what we read or hear in the news is noise, not meaningful information. Yet, we are drawn to the noise, the drama, the immediacy. 

We are wired to pay attention to new information, even if it is irrelevant or misleading. This is why it is better to read history or philosophy, to engage with ideas and arguments that have stood the test of time. 

On the other hand, Monte Carlo simulations are a powerful tool, allowing us to understand randomness and predict outcomes in various fields, from historical events to stock market trends. These simulations can generate millions of random sample paths, revealing the predominant characteristics and potential scenarios. This is crucial in fields such as finance where understanding randomness is key to success.

However, the use of Monte Carlo simulations also highlights an important distinction between scientific and literary intellectuals. While literary discourse can be randomly generated and still make sense, true scientific knowledge cannot. This principle is demonstrated by the 'Reverse Turing Test', which posits that a human can be considered unintelligent if their speech can be replicated by an unintelligent computer and mistaken for human speech.

Finally, the concept of ergodicity suggests that over a long enough time scale, all possible scenarios will eventually occur. This has implications for fields like finance, where understanding long-term trends and potential scenarios is essential.

Are We Misinterpreting Randomness as Patterns in Our Lives?

This story revolves around two characters, Carlos and John, who represent the archetype of successful randomness fools in the financial markets. Carlos, an emerging-markets whiz, and John, a high-yield trader, both experienced substantial success due to market cycles. However, they also fell victim to the same cycles, losing vast fortunes and their jobs.

Carlos, a Harvard-educated economist, came from a Latin-American family. His wealth significantly grew by buying and selling emerging-market bonds, mostly from developing countries like Russia, Mexico, Brazil, Argentina, and Turkey. However, Carlos's success was short-lived. When the bonds' value started to dip, and instead of re-evaluating his strategy, he bought more, which ultimately led to his downfall.

John, on the other hand, was a corporate high-yield bonds trader. He made a fortune by acquiring cheap bonds that yielded a good rate of interest. However, when the bond values plunged, John, like Carlos, bought more instead of reevaluating his strategy and lost nearly all his wealth within days.

Both Carlos and John shared traits typical of bad traders - overestimating the accuracy of their beliefs, getting married to positions, changing their stories, having no predefined plan for losses, denying reality and lacking critical thinking. Despite these mistakes, they became incredibly successful due to the randomness of market cycles.

This tale serves as a cautionary reminder about the role of randomness in success and failure, especially in the financial markets. It challenges the Darwinian belief that the fittest always survive, illustrating how randomness can favor the unfit in the short run. However, in the long run, those who are overfit to a specific path may be more vulnerable to rare events, leading to their downfall.

Randomness Fools: The Rise and Fall of Carlos and John in the Financial Markets

In the world of finance and beyond, skewness and asymmetry play critical roles. The story of Steven Jay Gould, a renowned essayist and scientist, illuminates this concept. Diagnosed with a deadly cancer, Gould was initially told the median survival time was eight months. 

This median figure, he discovered, only meant half the patients die before eight months, and half survive longer. However, the average survival was much higher due to some patients living significantly longer. This discrepancy between the median and mean survival times highlighted the importance of understanding skewness—where outcomes are not evenly distributed.

Gould’s revelation applies beyond medicine. In gambling, for instance, one might have 999 chances in 1,000 of winning $1, but one chance of losing $10,000. Despite the favorable odds, the expected outcome is a loss, illustrating how the magnitude of potential losses can outweigh their probability.

This concept of skewed outcomes is crucial in financial markets. Terms like “bullish” and “bearish” often fail to capture the complexity of market behavior. For example, one might predict a 70% chance of the market rising slightly, but a 30% chance of a significant drop. Despite the higher probability of a rise, the potential for a large drop makes it wise to bet on the decline.

Financial strategists and commentators often miss this nuance, focusing on the frequency of events rather than their impact. Successful traders understand that it’s not how often you’re right that matters, but how much you gain when you are. Rare events, though infrequent, can have outsized consequences.

This understanding is reflected in the approach of traders who make asymmetric bets, aiming to profit from rare but significant events. They recognize that traditional statistical methods often fail to account for these outliers, leading to mispriced risks.

In essence, while everyday life might lean on averages and medians, in realms like finance and medicine, the true story lies in the extremes and the asymmetries. Understanding and leveraging these can mean the difference between success and failure.

Can Understanding Skewness and Asymmetry be the Key to Success in Finance and Medicine?

Imagine a world where an infinite number of monkeys pound away at typewriters. Eventually, one will type out the Iliad. This might sound impressive, but the chances are astronomically low. 

Now, if this lucky monkey knocks on your door with the Iliad in hand, would you bet your life savings on it producing the Odyssey next? Probably not. The same principle applies to many real-life scenarios, where past performance often misleads us into expecting future success.

In the business world, randomness plays a huge role. The sheer number of players means that some will inevitably succeed just by chance. For instance, Marc, a hardworking lawyer living on Park Avenue, feels like a failure because his wealth pales in comparison to his wealthier neighbors, despite earning $500,000 a year. This is the survivorship bias at work—Marc sees only the winners around him and overlooks his own substantial success compared to the broader population.

Survivorship bias also affects how we perceive the success of others. Bestsellers like "The Millionaire Next Door" highlight wealthy individuals who supposedly possess certain traits, ignoring the countless others who exhibited the same traits but didn’t succeed. In reality, many of these so-called successful strategies might just be luck, magnified by a favorable market or other random factors.

Consider the world of investment managers. If we simulate a fair game among 10,000 managers, some will inevitably have winning streaks purely by luck. These managers are then celebrated for their 'remarkable' skills, even though their success is statistically bound to happen. This illusion of skill also extends to fund managers, where the survivors are often just the lucky ones who didn’t fail yet. 

In real life, we often misinterpret random successes as skill. For example, medical treatments sometimes seem effective due to spontaneous remission, not the treatment itself. Similarly, investment strategies that appear to work may just be riding on market trends that won't last.

These biases make it challenging to distinguish between genuine skill and mere luck. We see successful people and assume their methods are replicable, ignoring the invisible failures. This leads to a distorted view of what truly drives success. So next time you see someone thriving, remember: it might just be the monkey who typed out the Iliad.

Distinguishing Skill from Luck: The Deceptive Nature of Survivorship Bias

Life is highly non-linear, and a small advantage can translate into a huge payoff. This principle is demonstrated in the sand-pile effect. Imagine building a sandcastle on the beach. Every grain of sand you add to the top raises the whole structure a little. But the castle is unstable and eventually collapses. It could be argued that the last grain of sand caused the disproportionate result of the castle's destruction.

Likewise, small advantages or even a tiny bit of randomness can lead to disproportionate success in life. Take Microsoft's Bill Gates, for instance. Is he the best in his business? Not necessarily. But a small advantage – the fact that more people use his software – has led to his disproportionate success.

On the other hand, randomness can also lead to failure. Think about actors auditioning for a role. The one who lands the lead role may not necessarily be the most talented, but a random factor – like a similarity to someone the examiner fell in love with – could lead to his success while others are left serving coffee at Starbucks.

Understanding this non-linear nature of life can help us navigate it more effectively. For instance, when making decisions, we tend to rely on heuristics – mental shortcuts that save time and effort – rather than rational thinking. While this can lead to biases and errors, it's a necessary part of our cognitive process.

So, whether we're building sandcastles or building a career, it's important to remember that life is non-linear. Small advantages and a bit of randomness can have a big impact on the outcome. And while we can't always predict or control these factors, we can be aware of them and factor them into our decision-making process.

Can a Tiny Advantage or a Bit of Randomness Lead to Disproportionate Success?

Odysseus, the cunning hero of Homer's "Odyssey," faced the enchanting sirens whose bewitching songs led sailors to their doom. He outsmarted them by filling his crew's ears with wax and having himself tied to the mast, resisting the deadly temptation. From this tale, Taleb, the author, learned that sometimes we must protect ourselves from our own instincts and emotions.

In his career, Taleb realized that he is not intelligent or strong enough to fight his emotions. Instead, he uses them to fuel his ideas and actions. He accepts that he can be fooled by randomness and is ruled by emotions. This realization makes him strive to be aware of it and mitigate its effects.

Taleb's emotions often respond to a different set of calculations than his brain, creating a dissonance. For instance, anger triggered by minor inconveniences like a honking driver is illogical, yet humans are wired to respond with hostility.

In the professional world, Taleb finds it crucial not to read comments on his work unless they are from respected individuals. This principle, called Wittgenstein’s ruler, states that unless the source of a statement is highly qualified, the statement reveals more about the author than about the subject. It reminds Taleb that comments from an anonymous reader reveal more about them, while those from a qualified person provide useful insights.

In the financial trading world, superstitions can creep in, creating illogical associations between actions and outcomes. For instance, Taleb once insisted on entering his workplace through the same entrance and wearing the same tie as on a day when he made significant profits. This behavior is similar to gamblers who develop rituals they believe influence their luck.

In Taleb's profession, he strives to distinguish between noise and signal. To cope, he employs strategies like turning off the sound on financial news channels, finding humor in the silent, exaggerated gestures of pundits, which strips them of their intimidating aura.

Ultimately, he acknowledges the gap between rational knowledge and emotional behavior. Tricks and self-awareness become essential tools, much like Odysseus's bindings, to navigate the unpredictable seas of life and maintain a semblance of control amidst chaos.

Trading Strategies from Odysseus: Navigating the Financial Odyssey amidst Chaos and Randomness

In ancient times, Greek post-classical philosopher, Carneades of Cyrene, challenged the Romans' perspective on justice. He used compelling arguments to sway the audience one day, and the next day, he convincingly contradicted his previous arguments. This bold move illustrated the uncertainty of knowledge and fluidity of beliefs. However, this display enraged Cato the Elder, a staunch traditionalist who persuaded the Senate to expel the Greek ambassadors, fearing their skeptical spirit would corrupt Roman youth. 

Probability, a concept that evolved from the teachings of ancient philosophers like Carneades, is not about the odds but the belief in alternative outcomes. It was first used in legal arguments by rhetoricians in 6th century BC Greek Sicily.

Skepticism was prominent among ancient thinkers before the rise of monotheism and communism. The Romans were open to various beliefs, unlike later societies where self-contradiction was seen as shameful. This can be seen in the character of Marquis de Norpois in Marcel Proust's novel, who openly contradicts himself and forgets his previous opinions, yet is shamed for it.

In contemporary times, contrasting views on consistency and self-contradiction emerge. While society often shames those who change their minds, legendary traders like George Soros thrive on flexibility, adapting swiftly to new information without being shackled by past opinions. This detachment from previous beliefs, termed "path dependence," is rare but vital for success in dynamic fields like trading.

Probability, initially intertwined with skepticism, evolved differently in mathematics, particularly in gambling theory. This led to the rise of "risk measurers" who, despite their claims, often fail to account for the unpredictability of real-world events. The collapse of Long Term Capital Management (LTCM) in 1998, spearheaded by Nobel laureates who underestimated market complexities, highlighted the limitations of their probabilistic models.

Science, though inherently fallible, progresses through the acknowledgment of errors. Yet, many scientists resist admitting mistakes, attributing failures to rare events rather than flawed methodologies. This reluctance underscores the importance of embracing fallibility, acknowledging mistakes and adapting accordingly.

Can Embracing Skepticism and Flexibility, Like George Soros and Carneades, Lead to Greater Success?

Understanding randomness and decision-making is crucial. We often judge a decision based on its outcome, which isn't always correct. It's important to remember that a good decision doesn't always lead to a good outcome and vice versa. This is because our world is deeply entwined with randomness, and often, the results we experience are due to chance rather than skill or wisdom. 

In financial markets, risk managers aim to prevent institutions from playing Russian roulette. However, they can't fully control or predict the randomness inherent in financial markets. Our minds are wired to seek patterns and create meaning from the randomness of life, but this instinct can lead us astray. 

There's a thrill in trading, but it's not always about the wealth. It's about the game and the unpredictability of the market. While some traders may appear more successful due to risky high-yield trading, their wealth can be fleeting, as it's often based on luck rather than skill. 

Understanding and managing randomness is key to success in various fields, from finance to medicine. Monte Carlo simulations are a powerful tool in this regard. However, the use of such simulations also highlights the difference between scientific and literary intellectuals. 

Over a long enough time scale, all possible scenarios will eventually occur. This concept, known as ergodicity, has implications for fields like finance, where understanding long-term trends and potential scenarios is essential. 

In reality, many so-called successful strategies might just be luck, magnified by a favorable market or other random factors. Survivorship bias also affects how we perceive the success of others. We often misinterpret random successes as skill. 

While our cognitive processes often rely on heuristics, being aware of the non-linear aspects and the role of randomness can inform our decision-making process. In the professional world, it's crucial to differentiate between noise and signal, and to develop strategies to act rationally despite our emotional instincts. 

In essence, acknowledging the significant role of randomness in our lives, and understanding the non-linear nature of life can provide a more realistic perspective on our achievements and failures, and help us make better decisions.
