How does it work? Why is it dangerous to society? Who does it help?<\/p>\n\n\n\n<p>Cumulative advantage is the idea that small gains compound over time. In the work of <a href=\"https:\/\/www.shortform.com\/blog\/nassim-nicholas-taleb\/\">Nassim Nicholas Taleb<\/a>, cumulative advantage refers to <strong>the innate human tendency to flock to past successes, regardless of whether those successes are the product of merit or chance<\/strong>.<\/p>\n\n\n\n<p>We&#8217;ll cover cumulative advantage, where it&#8217;s most prominent, and <a href=\"https:\/\/www.shortform.com\/blog\/why-the-rich-get-richer\/\">why the rich get richer<\/a>.<\/p>\n\n\n\n<!--more-->\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Extremistan vs. Mediocristan<\/strong><\/h2>\n\n\n\n<p>Before we can understand Taleb&#8217;s notion of cumulative advantage, we need to understand his terms &#8220;Extremistan&#8221; and &#8220;Mediocristan.&#8221;<\/p>\n\n\n\n<p>To explain how and why <a href=\"https:\/\/www.shortform.com\/blog\/black-swan-theory\/\">Black Swans<\/a> occur, Taleb coins two categories to describe the measurable facets of existence: <a href=\"https:\/\/www.shortform.com\/blog\/extremistan\/\">Extremistan<\/a> and <a href=\"https:\/\/www.shortform.com\/blog\/mediocristan\/\">Mediocristan<\/a>.&nbsp;<br><\/p>\n\n\n\n<p><strong>In Mediocristan, randomness is highly constrained, and deviations from the average are minor. <\/strong>Physical characteristics such as height and weight are from Mediocristan: They have upper and lower bounds, their distribution is a <a href=\"https:\/\/www.shortform.com\/blog\/the-bell-curve\/\">bell curve<\/a>, and even the tallest or lightest human being isn\u2019t much taller or lighter than the average. <em>In Mediocristan, prediction is possible.<\/em> Cumulative advantage isn&#8217;t a huge issue here, as we&#8217;ll see.<br><\/p>\n\n\n\n<p><strong>In Extremistan, however, randomness is wild, and deviations from the average can be, well, extreme.<\/strong> Most social, man-made aspects of human society\u2014the economy, the stock market, politics\u2014hail from Extremistan: They have no known upper or lower bounds, their behavior can\u2019t be graphed on a bell curve, and individual events or phenomena\u2014i.e., Black Swans\u2014can have exponential impacts on averages. This is the world where cumulative advantage runs rampant.<br><\/p>\n\n\n\n<p>Imagine you put ten people in a room. Even if one of those people is Shaquille O\u2019Neal, the average height in the room is likely to be pretty close to the human average (Mediocristan). If one of those people is Jeff Bezos, however, suddenly the wealth average changes drastically (Extremistan).<br><\/p>\n\n\n\n<p>Although one needs only an intuitive sense of phenomena like wealth and market returns to understand that they don\u2019t adhere to the same rules as phenomena like height and weight, throughout the book Taleb provides a robust theoretical and statistical scaffolding for his claims about the differences between Mediocristan and Extremistan.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Cumulative Advantage<strong> in Extremistan<\/strong><\/h2>\n\n\n\n<p>As exemplified by figures like Beyonc\u00e9 and Jeff Bezos, social and economic advantages accrue highly unequally in Extremistan.<br><\/p>\n\n\n\n<p>One reason for this disparity is the \u201csuperstar effect.\u201d Coined by economist Sherwin Rosen to describe the unequal distributions of income and prestige in Extremistan sectors like stand-up comedy, classical music, and research scholarship, the \u201csuperstar effect\u201d operates when marginal differences in talent yield massive rewards.<br><\/p>\n\n\n\n<p>The <a href=\"https:\/\/www.shortform.com\/blog\/superstar-effect\/\">superstar effect<\/a>, it\u2019s vital to note, is meritocratic\u2014that is, those with the most talent, even if they\u2019re only slightly more talented than their competitors, get the spoils. <strong>What a theory like Rosen\u2019s fails to take into account, however, is that all-important aspect of life in Extremistan: <em>dumb luck<\/em><\/strong>. Luck can lead to cumulative advantage.<br><\/p>\n\n\n\n<p>Consider research scholarship for instance. Sociologist Robert K. Merton has observed that academics rarely read all the papers they cite; rather, they look at the bibliography of a paper they <em>have <\/em>read and pick sources to cite more or less at random.&nbsp;<br><\/p>\n\n\n\n<p>Now imagine a scholar cites three authors at random. Then a second scholar cites those same three authors, because the first author cited them. Then a third does the same thing. Suddenly the three authors that have been cited are considered leaders in their field, all by dint of dumb luck.<br><\/p>\n\n\n\n<p>The phenomenon identified by Merton\u2019s study has been called both \u201ccumulative advantage\u201d and \u201cpreferential attachment.\u201d These concepts describe<strong> the innate human tendency to flock to past successes, regardless of whether those successes are the product of merit or chance.<\/strong><br><\/p>\n\n\n\n<p>Although cumulative advantage\/preferential attachment provides a better account of unfairness than the superstar effect\u2014because it accounts for randomness in the distribution of advantage\/preference\u2014it still isn\u2019t a perfect theory of Extremistan unfairness. This is because, according to cumulative advantage\/preferential attachment, winners stay on top. Once an entity\u2014a company, an academic, a professional sports coach\u2014reaches a certain <a href=\"https:\/\/www.shortform.com\/blog\/levels-of-success\/\">level of success<\/a>, cumulative advantage\/preferential attachments holds that that entity will <em>continue <\/em>to be successful, because humans naturally favor past success. But this doesn\u2019t reflect reality.<br><\/p>\n\n\n\n<p>For example, according to cumulative advantage\/preferential attachment, Apple will forever be the king of consumer electronics, and Google will forever own the Internet. But even a cursory knowledge of business history shows a belief like this to be misguided. Consider this: If you tracked the 500 largest U.S. companies from 1957 to 1997, you\u2019d discover that only <em>74 <\/em>lasted the full 40 years. Some ceased to exist by virtue of mergers, but most simply failed. <strong>In other words, even in Extremistan, giants can occasionally be toppled by dwarfs<\/strong>.<br><\/p>\n\n\n\n<p>Nevertheless, despite the possibility of creative destruction, Extremistan is defined by extreme <em>concentration<\/em>\u2014of prestige, income, capital, influence, size, or what have you. <strong>These concentrations create the <em>appearance<\/em> of stability\u2014larger, more powerful entities are more resilient\u2014but they actually create the potential for catastrophic black swans<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is cumulative advantage?
