Most of his books follow a similar pattern: identifying counter-intuitive things about how the world works. In this book, the theme is in the subtitle. In BLINK, it was about the power of snap judgments (contradicting considered wisdom *not* to rely on intuition); OUTLIERS explores the role of environment (and by extension, chance) in success stories. I read those too. Next was WHAT THE DOG SAW, a collection of essays, which I haven&#8217;t read, then three others, which I didn&#8217;t even buy. Most recent is REVENGE OF THE TIPPING POINT, in 2024, which revisits some of the themes of the first book, from different perspectives.<\/p>\n<p><!--more--><\/p>\n<p>Gladwell has been criticized on a couple grounds, one for oversimplifying complex ideas, two for relying too heavily on anecdotes. But he inspired many other writers, who were often more rigorous than he was in analyzing data, since they were scientists and he was not; one that comes to mind is Jesse Bering&#8217;s THE BELIEF INSTINCT (reviewed last year <a href=\"https:\/\/www.markrkelly.com\/Blog\/2025\/09\/06\/jesse-bering-the-belief-instinct\/\">here<\/a>).<\/p>\n<p>This book and his others came to mind recently what with a couple of my running themes.<\/p>\n<p>First, the world is complex, in contrast to the simplistic takes of many conservatives. This is because our &#8220;common sense&#8221; and intuition (like Trump&#8217;s gut feelings) are evolved responses to living in the ancestral environment that humanity moved away from only about 12,000 years ago, and so don&#8217;t necessarily apply in the modern environment (which is far more complex).<\/p>\n<p>Second, because I now perceive several parallel trends in book publishing and ideas of the past thirty or more years. One are the similar books on parallel themes, as with Levitt &amp; Dubner&#8217;s FREAKONOMICS in 2005, that also uncovered non-intuitive truths behind things everyone thought they understood, in economic terms. (That book had several sequels and inspired a long-running NPR radio show, running to this day.) Second is the theme of psychological biases that lead people to believe &#8220;weird&#8221; things, as Ariely and Shermer and many others have written about. And another are the discoveries of physics, going back at least to the 1980s, that reveal how reality does not work in predictable manners, and in fact can exhibit amazing complexity as a result of some basic concepts: recursion, fractals, chaos, complexity, emergence, and of course evolution. The big picture writers, like Deutsch and Carroll, show how they fit together. (And all of their insights constitute the &#8220;literacy&#8221; about the real world I&#8217;ve mentioned recently; one could contrast that with the &#8220;demon-haunted&#8221; world of the intuitivists and the gullicists.)<\/p>\n<p>And so for example Gladwell&#8217;s idea of a tipping point is analogous to the notion in chaos theory that a single event, like the fluttering of a butterfly, can trigger enormous, unpredictable events, like hurricanes. That&#8217;s the way of the world, at multiple levels.<\/p>\n<p>So here are the notes I took on this book, even though the general principles just outlined are my point today, more than the particulars of Gladwell&#8217;s examples.<\/p>\n<p style=\"text-align: center;\">*<\/p>\n<p><strong>Introduction<\/strong><\/p>\n<ul>\n<li>Author recalls how Hush Puppies [a kind of shoe] suddenly became popular again, after a few people in downtown Manhattan nightclubs starting wearing them to be retro; or how crime in NY went down after several decades, for no obvious reason.<\/li>\n<li>Such changes resemble the way epidemics occur, characterized by three elements: a phenomenon that\u2019s contagious (that spreads without being planned); that little changes have big effects; and that the effects occur within a short span of time. When these conditions occur it\u2019s a \u2018tipping point\u2019, which is like a critical mass, a threshold, a boiling point; as when rain turns to snow.<\/li>\n<li>But why do certain ideas start such epidemics and others don\u2019t? That\u2019s the topic of this book.<\/li>\n<\/ul>\n<p><strong>Ch1\u2014The Three Rules of Epidemics<\/strong><\/p>\n<ul>\n<li>In Baltimore syphilis rates jumped, and various explanations were offered: the prevalence of crack cocaine; increased police action; cutbacks in city health services.<\/li>\n<li>Whatever the \u2018true\u2019 reason, such shifts are characterized by three laws of change:<\/li>\n<li><strong>The Law of the Few<\/strong>: it takes only a few people to shift the tide, as in the so-called 80-20 rules (80% of traffic accidents are caused by 20% of drivers, etc.)<\/li>\n<li><strong>The Stickiness Factor<\/strong>: something happens that makes a small change \u2018stick\u2019, as when a single person spreads a disease, e.g. Patient Zero in the spread of HIV, or the fact that HIV itself changed at some point (cf. evidence that an early form of HIV spread early in the 20<sup>th<\/sup> century)<\/li>\n<li><strong>The Power of Context<\/strong>: the spread of disease is influenced by the seasons, with transmission greater during winter months when people are in closer contact; or the way people react to public emergencies\u2014the more witnesses, the less likely any one will react (cf Kitty Genovese)<\/li>\n<\/ul>\n<p><strong>Ch 2\u2014The Law of the Few (p30-88)<\/strong><\/p>\n<ul>\n<li>The classic word-of-mouth epidemic was Paul Revere\u2019s ride. Yet another rider took a similar trip, but no one remembers him. Why are only certain people effective?<\/li>\n<li>Three kinds of people facilitate such epidemics\u2014<\/li>\n<li><strong>CONNECTORS<\/strong> are those few people who know lots of other people, by virtue of their personality. E.g. the six degrees of separate experiment; the 250 names experiment; Kevin Bacon and other actors; people the author cites Roger Horchow and Lois Weisberg. Ironically it\u2019s the \u2018strength of weak ties\u2019 that\u2019s effective\u2014the many people they know aren\u2019t friends, they\u2019re acquaintances.<\/li>\n<li><strong>MAVENS<\/strong> are information specialists, market mavens, those who obsess about finding the best deals and offers and passing along tips to everyone they know. Zagat volunteers are an example. But these are teachers, not necessarily persuaders.<\/li>\n<li><strong>SALESMEN<\/strong> are those who do persuade, sometimes unconsciously, e.g. news anchormen who expressions vary depending on which candidate they\u2019re talking about. Or students told to nod their heads while listening to an editorial introduces a bias into their reaction to the editorial. A little bias can have a big effect. Studies show subtle effects such as micro-movements of two people in conversation, they way they move or react, affects whether one person finds the other persuasive.<\/li>\n<\/ul>\n<p><strong>Ch 3\u2014The Stickiness Factor<\/strong><\/p>\n<ul>\n<li>Why are some things more effective than others? In the late \u201860s the children\u2019s tv show Sesame Street was created; despite conventional wisdom that TV entertained but wasn\u2019t involving, the show was a great success, in terms of teaching children.<\/li>\n<li>Other examples: a direct marketing campaign for Columbia Record Club was improved greatly by the simple addition of a \u2018gold box\u2019 game on the form. And a study on warning college students of the danger of tetanus weren\u2019t affected by whether \u2018scare\u2019 tactics were used\u2014the benefit occurred [more students got inoculated] by the simple measure of including a map to the student health center on the flyer.<\/li>\n<li>Sesame Street was rigorously tested with real children, and violated various kinds of conventional wisdom. It turned out children watched more intently not when they were \u2018stimulated\u2019, but when they *understood* what they were watching. They were told not to mix reality and fantasy, but tests showed greater attention when they were mixed. (p105b). They did eye-tracking tests..<\/li>\n<li>In the \u201890s, another TV show was even more successful\u2014was even stickier\u2014by changing some of the SS formula. Blue&#8217;s Clues. It was slow and deliberate, literal rather than clever, and each episode was repeated 5 times a week\u2014because kids were confused by SS\u2019s wordplay, responded better to overall narrative arcs rather than commercial bite-sized 3 minute episodes; and like repetition, at least up to age 5 or so.<\/li>\n<li>It\u2019s all about packaging the same information in slightly different ways; little changes in packaging greatly improve how well the message is conveyed.<\/li>\n<\/ul>\n<p><strong>Ch 4\u2014The Power of Context (Part One)\u2014Bernie Goetz<\/strong><\/p>\n<ul>\n<li>In 1984 Bernhard Goetz got on the subway (at 14<sup>th<\/sup> St &amp; 7<sup>th<\/sup> Ave) and was accosted by several black men, whom he shot&#8230;<\/li>\n<li>Crime in NY was epidemic; it had tipped. The key to reversing it was the \u2018<strong>Broken Windows\u2019<\/strong> theory\u2014that small expressions of disorder in a neighborhood, such as graffiti or broken windows, would invite more serious crimes. Clean up the graffiti and windows and the context is changed.<\/li>\n<li>So the subway was rebuilt and cleaned up, each car being reclaimed one by one.<\/li>\n<li>The principle is contrary to traditional theories of inherent\/genetic predisposition for criminal behavior.<\/li>\n<li>Other examples\u2014<\/li>\n<li>The notorious Stanford \u2018prison experiment\u2019 in the 1970s, which was called off when those assigned to be \u2018guards\u2019 became too abusive.<\/li>\n<li>Surveys in the 1920s about whether students cheat. People over-estimate fundamental traits of a person, without taking the situation into account. The effect of birth-order is apparent only when people are around their families\u2014otherwise it doesn\u2019t matter.<\/li>\n<li>Another example\u2014Good Samaritans who do, or do not, stop to help someone depending on how much of a rush they are in.<\/li>\n<\/ul>\n<p><strong>Ch 5\u2014The Power of Context (Part Two)\u2014The Magic Number 150<\/strong><\/p>\n<ul>\n<li>Case study Rebecca Wells\u2019 <em>The Divine Secrets of the Ya-Ya Sisterhood<\/em>, which sold only meekly before taking off in paperback sales, an effect attributed to various reading groups, especially on the west coast. The key is that these groups are relatively small, and that the groups reinforce the message&#8230;<\/li>\n<li>The way a movie plays in a theater with other people; religious messages spread; book groups.<\/li>\n<li>Humans have a limited \u2018<strong>channel capacity\u2019<\/strong> \u2013 people tend to sort things into not more than about 7 categories.<\/li>\n<li>Findings show brain size of primates correlates with the group size they tend to congregate in.<\/li>\n<li>For humans the limit is <strong>about 150.<\/strong> Military units, colonies, etc., tend to splinter whenever the size grows to exceed this number. Behavior changes; it\u2019s no longer possible to know everyone in a larger group.<\/li>\n<li>Lesson: keep the groups small. Gore Associates (maker of GoreTex etc) keeps each plant to 150 employees, even if several plants are located right next to one another.<\/li>\n<li>They employ the principle of \u2018transactive memory\u2019\u2014one person doesn\u2019t have to know everything, if he knows where to find what he needs to know. This operates between married couples and families, with different members \u2018specializing\u2019 is certain tasks or kinds of knowledge.<\/li>\n<\/ul>\n<p><strong>Ch 6\u2014Case Study: Rumors, Sneakers, and the Power of Translation<\/strong><\/p>\n<ul>\n<li>Airwalk shoes, originally marketed to hardcore skateboarders. Their advertising followed the classic diffusion model\u2014<strong>Innovators, early adopters, early majority, late majority, laggards<\/strong>. There\u2019s a chasm between the early adopters and early majority\u2014this is where the connectors, mavens, and salesmen are needed. They \u2018translate\u2019 the message to the masses in the same way rumors are spread \u2013 by taking a specific case and changing it through leveling, sharpening, and assimilating the message.<\/li>\n<li>Airwalk\u2019s ad agency used DeeDee Gordon, a \u2018maven\u2019 who sought out innovators and queried them regularly about new trends. [she\u2019s a \u2018coolhunter\u2019 in later parlance] She applied those trends to the Airwalk advertising.<\/li>\n<li>But it didn\u2019t last\u2014Airwalk went so mainstream it turned off the specialty crowd.<\/li>\n<\/ul>\n<p><strong>Ch 7\u2014Case Study: Suicide, Smoking, and the Search for the Unsticky Cigarette<\/strong><\/p>\n<ul>\n<li>In Micronesia in the late 60s there was an epidemic of suicides, mostly among teenage boys, who would hang themselves over seemingly trivial matters\u2014being yelled at by their parents, or unable to decide between two girlfriends. Once started, other followed, being imitative as a sort of self-expression.<\/li>\n<li>Similar to the epidemic of teenage smoking in the west.<\/li>\n<li>Teens know that smoking is dangerous; yet anti-smoking campaigns backfire.<\/li>\n<li>The suicides were contagious because news of one in effect gave people \u2018permission\u2019 to do the same\u2014created a context for that kind of behavior.<\/li>\n<li>With smoking, there\u2019s a strong correlation with feeling \u2018sophisticated\u2019. Smokers trend toward a specific, extrovert personality type. They don\u2019t smoke to become cool; they smoke because they\u2019re cool.<\/li>\n<li>The environmental influence is about peers, not parents. So trying to control the \u2018salesman\u2019 won\u2019t work.<\/li>\n<li>The way to control the episode is to address the \u2018stickiness\u2019\u2014the addictive quality of nicotine. Not all kids who try smoking stay with it\u2014depending on varying tolerances to nicotine, perhaps. There\u2019s also a link between depression and heavy smoking; treat the former, and the latter becomes easier to control.<\/li>\n<li>Hardcore drugs, for example, are not actually very sticky\u2014only a small percent of those who try become regular users.<\/li>\n<li>Remove the absolutist implication that exposure =&gt; addiction. Make it ok for kids to experiment.<\/li>\n<\/ul>\n<p><strong>Conclusion<\/strong><\/p>\n<ul>\n<li>A final example: San Diego found that the place to spread awareness of diabetes and breast cancer in the black community was in\u2014beauty parlors. Captive audiences where people had time to receive new information.<\/li>\n<li>Lessons:<\/li>\n<li>First, starting an epidemic requires putting resources to a few key individuals\u2014even if they seem like \u2018band-aid\u2019 solutions.<\/li>\n<li>Second, the world doesn\u2019t accord with our intuitions\u2014what we do must be tested.<\/li>\n<li>And finally\u2014things can be changed.<\/li>\n<\/ul>\n<p>\\\\<\/p>\n<p>Comments from 2005:<\/p>\n<p>Interesting to consider anti-gay efforts in this context. The motivation of those who would ban books, etc., relates to the \u2018power of context\u2019; it presumes that the mere mention of the existence of gays will sway children into that lifestyle\u2014giving them \u2018permission\u2019 to engage in a possible kind of behavior. This is the same notion that violence on TV and in movies is unhealthy because it could result in real violence&#8230;<\/p>\n<p>There\u2019s a certain validity in this, but the anti-gays also presume great \u2018stickiness\u2019, that is, if their kids try it once, they\u2019ll like it and never have kids of their own, propagating the species and family name. This might well be true in some cases\u2014the cases where a person would remain an unhappy heterosexual in a more repressive society. Yet the fears of the anti-gays seem excessive\u2014do they really believe the allure of gay sex is so great as to be such a threat?<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Subtitled: &#8220;How Little Things Can Make a Big Difference&#8221; (Little, Brown, March 2000, 279pp, including 20pp endnotes, acknowledgements, and index) This was a popular and well-received book when published back in 2000, and launched\u00a0Gladwell&#8216;s book career.
