How Ideas Spread

Rate this book
What makes one novel a bestseller, while a similar work languishes unnoticed? Why are the same few baby names suddenly everywhere? Why is everyone talking about that viral video?

Welcome to the science of social epidemics: the cutting-edge study of why some ideas, products, and concepts spread wildly, while others quickly flame out.

Anyone who has something to sell, a cause to promote, or a message to spread knows that there are obstacles in creating a message that resonates, spreads, and sticks to make their product or idea the word on the street.

Enormous sums of time and money have been spent trying to answer the question of why some ideas catch on. And not only is it an ever-present challenge for businesses, governments, and organizations, but it has long been a source of inquiry for psychologists, economists, and sociologists as well.

Now, in How Ideas Spread, discover what researchers studying the science of social transmission have learned. Taught by Jonah Berger - a best-selling author, expert in social dynamics, and faculty member at the Wharton School - this enlightening course draws on lessons from business, social psychology, economics, and popular culture to give you the cross-disciplinary tools necessary to identify and promote contagious ideas that last.

Across 12 half-hour lectures filled with absorbing stories and intriguing information, you'll learn the psychological and sociological mechanisms that lead products, ideas, and behaviors to catch on, plus specific techniques that can be applied in your personal and professional life, whatever your field or interest. Listen to one powerful case study after another to find out how to leverage three main concepts—individual psychology, social influence, and social networks—to design infectious messages. Whether you're a professional seeking guidance on crafting products and messages that grab hold, or you just want insights into how viral trends work, this course will open your eyes to the power of contagious ideas.

Runtime: 5 hours, 53 minutes.

The Great Courses provide 12 lectures by Professor Jonah Berger on How Ideas Spread.

I was looking forward to learning why things “catch on” and the behavioral science that underlies why some flourish and others fail.

Berger’s methodology first provides us with some “basic science behind exposure, perception, and memory.” I already knew about triggers but Berger provides some interesting examples.

He next moves to a discussion of social influence and how other’s behavior affects and/or influences our own.

Finally, he put forward some conclusions about the pattern of connections between people and how that impacts the spread of information and influence.

The approximately half-hour lectures are full of easily digestible bites of popular science, surveys and interesting facts. I don’t regret the time I spent listening to Berger, but I am not sure what I learned is going to make me any more talented or able to distinguish something new of great value from something that is just a “flash in the pan.” I did absorb why wine shops play certain kinds of music and why where my poling place is located (school, church, fire station) might affect how I vote.

Now on to a course on one of my favorite topics: wine. Hoping to report on that later this month.

I'm about half-way (and plan to finish), but wanted to start a review. I love The Great Courses. They seem to be similar to 100-level college courses without the midterms/finals. The professors usually use academic language one would expect from a entry-level course in the subject.

How Ideas Spread has posited numerous statements so far that do not distinguish between correlation and causation. Prof Berger will instead leap to the assumption that, say, having an open vowel sound in a potential name for a car will cause a person to believe the car to be roomier when compared to a similar sounding car name with a less open vowel sound. The single study points to there being a correlation in this case, but without more data it seemed irresponsible conclude causality.

Sometimes it's very useful to speculate about causality when there isn't enough information to prove it yet, but academics will usually point out when this speculation is happening. So far, this book/course seems to be more inline with a marketing book in the business improvement section of a bookstore rather than an entry-level academic/scientific explanation of how ideas spread.

Not necessarily a bad book at all, but it's different than what I expect from a Great Courses title.

I’m not sure which this book informed more, how to ensure ideas spread or those methods people use to spread ideas that are ineffective. Either way, the book was informative and easy to follow.

Recommend for those looking to ensure their ideas stick initially, gain traction, and spread over time.

This is a good series of lectures. The professor presented several ideas that I (surprisingly) hadn't heard before regarding viral marketing and did not simply rehash the thoughts and philosophies of other business strategists. The professor is highly knowledgable - his ideas were well spoken and he presents his concepts with clear articulation.

Enjoyable and informative. Marketing has been a part of every aspect of my career years. I spent nearly 20 years of that time in a marketing department focused primarily in print media, but which evolved into web interfaces starting back in the early 2000’s, like everyone had to.
Not always exciting working the trenches of paginating and distributing sales catalogs, especially in a business to business environment, but the world of marketing overall is very interesting as a career. Developing an idea from infancy to user interface and then evolving it again as user tastes and needs evolve is something I still find fascinating... but it is sometimes difficult to predict successes and failures since they are often brought on by outside forces.

This course provides an interesting type of consumer perspective examination which is quite similar to the difference between looking at a photo (taken in fixed lighting from a single angle) to that of watching a virtual guided tour given by way of a drone video operated by a skilled tour guide.

The lecturer zooms into focused parts of the subject matter and allows the reader to get a 3D view of many alternate campaigns and user perspectives about those campaigns. He includes details on the results of those efforts and often indicates the margins by which they either succeeded or failed.... then explains why.
Highly useful considerations, even for people interested in or currently pursuing careers that involve only light marketing.

Have you ever wondered why some things stick in memory and others are quickly forgotten? Professor Jonah Berger shows how through introducing the reader/listener to a new language that explains how ideas spread in American culture today. He introduces the four principles of human memory or simplicity, unexpectedness, concreteness and credibility which tend to be "stickier" and thus more memorable. These ideas lead to beliefs, open doors to a need to belong and thus to be identified with things that make the "world go round." Chapters include Social Epidemics-Why Things Catch On, The Basics of Consumer Psychology, The Social Influence of Conformity, Word of Mouth; Powerful and Persuasive, The Social Currency of Shared Ideas and Messages that go Viral. Fast paced and with a message of multilevel meaning about how ideas spread, The Great Course, How Ideas Spread feels like learning a new language, the language of the quickly evolving American scene.

Interesting lectures that address elements of personal psychology, network theory, and influence theories. The work has a strong focus on what marketing research can tell us, since that is where most of the relevant research was done, but Berger does a nice job of explaining how those results apply more broadly to ideas spreading in general. A nice connection of his own research to the work of others.

I was particularly intrigued by his arguments against two widely discussed tropes: (a) that social media has fundamentally changed the communications that influence us, and (b) that there are certain persons who are more important influencers for everyone, and therefore worth paying for their social influence. He does a nice job of showing how there are ways in which popular people sometimes influence some people, but that word-of-mouth from friends are always more important drivers of idea acceptance.

Well worth the time to listen.

An interesting exploration of the conditions that cause some things to catch on and others not to. The information was fascinating and the presentation easy to follow (audiobook). The only downside was that the author sometimes laboured a point till I felt like screaming ‘I've got it already - let’s move along please.' In sum though, I learned quite a lot about human behavior and how this influences trends. Interestingly, some of this is counter-intuitive.

The author has a very clear and pleasant speaking voice - crucial to the success of a recorded series of lectures - and a good sense of humor which lightened the topic and made his examples more memorable. It was a really worthwhile listening experience.

Summary: This is a "Great Courses" audio course, so it's a series of lectures about "How Ideas Spread". Topics covered include consumer psychology, word of mouth, and social networking.

Review: I enjoyed this. I thought that the ideas were really interesting and might be helpful as I try to advertise for my library/business. It is a little outdated, but only by a few years -- nothing major. It was just a little bit noticeable.

This is a marketing 101 set of lectures. It has some insightful ideas and some things to ponder and for a group of 12 lectures this is all you can ask for.

I dislike reading about money and yet time and again I end up reading about it, from different angles, sure but at the end of the day it's still how to sell shit. This hurts my poet's soul. Life is more than a transactional enterprise...sigh.. that was my scream to the void. All in all a good set of lectures with an engaging speaker.

I greatly appreciate lectures and books based on research and this is one of them (consider reading/listening to his book Contagious). The insights given for how things catch on are amazing and very useful in many instances. The insights help understand our social interactions also. This is well worth hearing.

A couple years later I still find myself thinking about some of the things he talked about in the lecture series. For instance how if one person is staring at the sky people will walk around them, but if three people are others will stop and stare too.

It's an interesting blend of psychology, marketing, sociology and worth the listen.

A decent but not groundbreaking offering from The Great Courses. This text covers a lot of ideas in marketing and sociology, examining what makes certain ideas stick or "go viral," as the kids say nowadays. There is not really a clear thesis of how this process works, but the investigation is engaging and accessible for listeners.

A "meh" book. Covers more marketing fundamentals than I would have liked. Covers some good questions, like how or if one would price a social network influencer for their advertisement, but doesn't really go into detail on the mechanics. Great for beginners

Not what I expected (I expected more sociology than marketing) but still an interesting and educational read

Decent book, much of the same content as his book “Contagious” with ideas you can apply if the attention economy matters to you

It's a good introduction to psychological and sociological aspects influencing the potential of ideas to spread and make an impact.

A good overview of the subject. Topics are presented in a manner appropriate for beginners. You don't need years of marketing experience to appreciate the course.
