The term "cognitive surplus" refers to the surplus of "intellect, energy, and time" that people have. Since most people have a 40-hour work week, there they have surplus time on their hands to do as they wish. This is a very passive activity.

In the past, many people spent time doing things like having picnics, going bowling, and other family and community activities. But when television came along, people replaced their active pursuits with television, a purely passive pursuit. Clay Shirky main

The Guardian published early June 2011 the list with the 100 greatest non-fiction books. Clay Shirky’s Here comes everybody was included in the politics section. Clay Shirky released his book Cognitive surplus with as subtitle “How technology makes Consumers into Collaborators“. Having read his first one (and still being impressed) I decided to read his Cognitive Surpluss.

Clay Shirky teaches at the Interactive Telecommunications Program at New York University, where he researches the interrelate

The topics in this book are wide-ranging (and Shirky's analysis polymathic and trenchant), but I've been thinking a lot about that ongoing global civil suit Professional v. Amateur lately, and, in lieu of an (amateur =P) review, I wanted to just post some quotes from the book on Professional v. Amateur without comment.

Previously, I'd been using this (in the voice of Denise, a successful professional chef) from The Corrections to frame things:

I liked this book less than Here Comes Everybody but mostly because I don't think Shirky needed to write another ethnography. His last book was such a complete anthropological snapshot of how we share and collaborate with the technology available to us. This book is an extension of that and, while interesting, I was hoping that he might assert a hypothesis about what we will do with this collaboration. He really doesn't.

Shirky makes the point that we use our spare time to collaborate in ways th

Shirky opens up an intellectual space for his book with several crucial, almost obvious, yet often overlooked claims:

1. the current generation of young people are the first generation watching *less* TV than the previous generation
2. this extra time or cognitive surplus is often dedicated to production rather than pure consumption
3. participatory culture is a call back to the traditional past

From this crafted space he soundly argues that we should stop listening to those people lamenting the ris

Shirky picks up where he left off from "Here Comes Everybody," describing in finer grain the behaviours underlying the results of specific collective actions that have been powered by social media. His writing reads like a field guide for makers in the space, highlighting potential potholes in thinking, making it invaluable reading for those wondering how the opportunity presented by social media can be channeled towards civic action and innovation.

It's very interesting to read this book at the

I was right there with Shirky at the beginning, but as this book progressed, I got more and more turned off by some of the latent assumptions buried in his thought process. Obviously, he's a very smart guy. And obviously, he really believes that social software and the current creator-culture are good things that can be very beneficial for society. But Shirky also has some pretty rigid values of his own that he clings to while attempting to dismantle other "traditional" values. He is a firm crea ...more

Clay Shirky is a wide known professor of media and great defender of internet based social technologies. The ideas presented in this book are at some points interesting and relevant, because they fight against the attacks these kinds of technologies always have to face when they emerge. However in doing that, and in such a short book, Shirky takes too much lightly the social aspects of life.

In short the cognitive surplus here talked about is the time you spend in the internet interacting, sharin

At one point, Prof. Shirky accurately deploys “begs the question”; had Cognitive Surplus not already been thoroughly enjoyable, adroit usage of the most frequently misapplied logical-device-turned-idiom throughout erudition brings great joy. Idiomatically, it has morphed in the bloviating, pompous version of “raises the question” and that is, of course, terribly wrong and absolutely nauseating (beware, nauseous).

It’s not that a reader wouldn’t be able to intuit “raises the question” from a faux-

Surplus cognitivo è un libro che dovrebbe leggere chiunque si interessamente, professionalmente o per diletto, di social media e social network. Clay Shirky, con una prosa molto leggera e coinvolgente, ci guida in quello che potrebbe essere l’immediato futuro. Un mondo in cui un piccolo spostamento di attenzione globale dai media passivi ad Internet potrebbe generare cambiamenti sociali impensabili.

Il libro è ricco di casi, alcuni già racontati sul suo blog (come il fatto che riprendersi l’1% di

Cognitive Surplus is written by the author Clay Shirky. He is also a teacher at New York University, where he teaches “New Media” at the Interactive Telecommunications Program. His previous book is called Here Comes Everybody where he tackled the subject of the power of the web for groups to organize. Shirky has also written for publications like The New York Times and Wired.

My first exposure to Clay Shirky was a talk he gave about the so called problem of information overload. In the talk he ex

Clay Shirky is a master at bringing meaning to the startling cultural and technological changes whirling through our lives. In Here Comes Everybody, Shirky provided context the revolution that is turning passive office workers into take-charge designers of their businesses’ corporate destinies. In his follow-up, Cognitive Surplus, he probes a bit deeper into what is propelling forward our individual creativity and the impulse to share and contribute to a collective output — what he calls “cognit ...more

This book picks up right where Here Comes Everybody: The Power of Organizing Without Organizations left off, both in content and in awesomeness.

I would say this is right up there for one of the best books I've read this year.

A few of the ideas that resonated with me:

- Many of the things we take for granted as a culture are merely 'accidents of history'. That large corporations have traditionally been the best way to organize people was more of a result of the tools of the time than an inherent n

I found this a fascinating read. He talks about how now, with the combination of surplus time in society (all time that has previously been spent in watching television) plus new opportunities to share and create online (think Wikipedia, Apache, online charities,, meet, pickupal etc.) that there are now amazing ways to use our cognitive surplus for public/civic good.

Shirky is one of those educators and social commentators people involved in organizations ignore at their peril. He describes a number of common pitfalls that relate to an old information and media economy and how changes are already here that invite people to connect with each other around what they love, share and produce to different social goods, and break past gatekeepers of culture and risk. He also describes what makes some of the communities and cultures exciting as they emerge from our ...more

We live in amazing times. For the majority of those of us who live in America, we have vast reservoirs of free time.

But how do we choose to use that free time? Sadly, for the last fifty years, we have spent most of it passively watching television, watching television to the exclusion of other more social, more fulfilling activities. Last year, in fact, Americans watched about two hundred billion hours of television. And, even more sadly, studies show that those who watch tv are less happy, mor

The three-star review reflects my frame of mind while reading this rather than the book's actual quality. It's good; puts a lot of what's happening with social and not-so-social media into context and, more important, uses global examples of which we haven't all heard already (part of the problem with any book that deals with the age of global connectivity is the domination by Americans and their ethno-cultural-centricity when reporting on what works and what doesn't - some of us will never indu ...more

Cognitive Surplus continues where Here Comes Everybody ends and examines how excess free time and the adoption of social media are transforming us from consumers into collaborators.

We've had surplus free time for a while, Shirky contents, at least since the postwar boom. However, because we spent so much of this excess time watching television, the surplus was mostly used for consumption. It has only been in recent years, with the emergence of online social networks, that we're beginning to see

When I saw Cognitive Surplus was published in 2010 (having already bought it), I was disappointed, expecting a book about social media that's five years old to have lost relevance. It hasn't. Well, maybe it has, but if it has it must have seemed like a godsend in 2010...

I turned to CS having just read about two chapters of a book called The Sceptical Optimist, which argues for a less techno-utopian approach to society. I mention that only because CS and TSO are about similar subjects, albeit app

One Main point:
Because of our wealth, we have more free time that we can use our brains for. Because of this and the power of scale we are able to do some cool things. Things such as Wikipedia and YouTube and open sourse can benefit from huge numbers of people now have large amount of free time. They are able to make some really cool things that could not have been made before. We spend some of this new free time watching TV and other less productive tasks but we are also making huge amounts of

I liked this book. It was well written, clear and interesting. I don’t have much to criticize in this particular piece, so below is my summary of the book’s content.

Free time is a relatively new phenomenon. We’ve only really had free time since shortly after the Great Depression. What do we do with all our wonderful free time? We watch sitcoms. At least, that’s what we did until the internet came about. Since the advent of social media, we have seen a huge increase in amateur creation. Rather t

Short, fluffy - an attempt to expand on what is a pretty short idea at core. If you read or watched any of his previous talks like "GIN, TELEVISION, AND COGNITIVE SURPLUS" and have followed some of his other writings, there's little new here for you. One advantage of being in book form is that he includes his references.

The main point is excellent. When dealing with change we seek relief. In the last half century it was TV. We watch billions of hours a year. No longer being forced to be consumers because of lower barriers to creativity and public expression, possibilities are limitless for what we do in groups and communities.

This could have also been written as a couple of essays; several examples have been covered better elsewhere.

I love Clay Shirky's stuff. I think this books has powerful implications for what the future of innovation will look like and who will power it. It's also a call to action. Less consumption, more production. What am I going to do with my cognitive surplus? What will you do with yours?

This was a really enthralling book, about a topic of more-than-average relevance. Shirky gives himself the task of answering the following question: what, in our age of modernity, are we supposed to do with the abundance of free-time in front of us? How do we utilise those hours in which both our mind and body are not preoccupied, vacant and ready for engagement? Well, according to Shirky we apply our collective brain power to intrinsically satisfying activities, which, because of their autonomo ...more

Clay Shirky has an interesting idea - that as we spend less time watching TV and more and more time on the internet engaging in collaborative activities (from Lolcats to Wikipedia), we create a kind of "cognitive surplus" that can accomplish pretty amazing things. He very strongly believes that any kind of media where people can engage as well as consume (as opposed to TV, where only consumption is possible) is a powerful thing that has the potential to change society at large. This is true, and ...more

Well written in a non academic style. He is a little hard on lolcats but intrigues one with all the possibilities to contribute.
I enjoyed it. I found it motivational, the indictment of tv to be particularly relevant, and the concepts interesting. The idea of the power of cognitive surplus - the thoughts and time of educated people - is important. The comparison of LOLCats and Wikipedia and Facebook groups, the idea of a continuum of contributions from this cognitive surplus, is powerful as a use of spare time. It broke down as first half aimed at the individual or the society as a whole, with the last bit aimed at develo ...more

En este caso, Shirky nos presenta el concepto del excedente cognitivo, que es todas las horas de tiempo libre que tenemos los ciudadanos de las sociedades civilizadas y que, gracias a las tecnologías de la información y la comunicación, ahora podemos poner en común para tareas tan triviales como comentar vídeos de gatitos o tan importantes como combatir el machismo violento en la India.
