A new field has emerged, carried by a surge of digital technologies. It is known as collective intelligence or crowdsourcing, which has a familiar ring but should not be confused with crowdfunding. Crowdsourcing refers to harnessing the power of a large number of people to implement a task or project to obtain information or to solve a difficult problem. The idea is that a group of people can offer greater insights and better answers than an individual can.
In its most restrictive meaning, collective intelligence is basically concerned with how groups of people cooperate online. In its broadest sense, it is concerned with how all kinds of intelligence happen on large scales.
This latest book by Geoff Mulgan is a perfect introduction to collective intelligence, a little-known discipline that “can change our world.” The book draws on subjects such as social psychology, computer sciences and economics, as well as the author’s experiences as co-founder of the think tank Demos.
The author, who has worked in government, charities, businesses and movements, believes there is a blatant need for more effective innovation to deal with challenges ranging from inequality to aging, climate change and conflict.
“I’ve been fascinated by the question of why some organizations seem so much smarter than others, better able to navigate the uncertain currents of the world around them. Even more fascinating are the examples of organizations full of clever people and expensive technology that nevertheless act in stupid and self-destructive ways,” writes Mulgan.
This leads us to ask how societies and governments are expected to solve complex problems, or in other words: How can a collective problem be resolved with a collective solution? “Collective intelligence has to be consciously orchestrated, supported by specialist institutions and roles, and helped by common standards. In many fields no one sees it as their role to make this happen as a result, the world acts far less intelligently than it could,” writes Mulgan.
This was the case with the Central Intelligence Agency (CIA) informing then-President George H. W. Bush that the Berlin Wall would not fall, while the news was showing just that. The financial crash of the late 2000s is another perfect example. Despite a plethora of data obtained through sophisticated information technologies, financial analysts, economists and journalists were unable to warn the world about the impending economic disaster.
Moreover, it is estimated that up to 50 percent of antibiotic prescriptions are unnecessary, 25 percent of medicines in circulation are counterfeit, and 10-20 percent of diagnoses are incorrect. Despite unprecedented access to medical data, we are still unable to use that information to make better decisions and improve our health.
Collective intelligence is not new. Thucydides’ description of how an army went about planning an assault on a besieged town is one of the first historical accounts of collective intelligence. First, ladders were made; their height was calculated by counting the layers of bricks on the side facing the town.
Nowadays, human eyes have been replaced by Dove satellites, the size of a shoe box, which orbit the globe. They have shown that the spread of night-lights in Myanmar reveals slower economic growth than the World Bank estimates.
In Kenya, they have provided the number of metal roofs, indicating that people are moving out of poverty. In China, Dove satellites have counted the number of trucks in factory parking lots, which denotes industrial output. Satellite pictures are replacing sophisticated statistics.
As machine intelligence has progressed enormously, there have been efforts to develop collective intelligence. The website Polymath encouraged people to help solve the hardest maths problems. It found that many minds could find solutions more successfully than mathematicians working alone.
The recent history of collective intelligence is a combination of humans and machines, organizations and networks. Google Maps is a perfect example. Google lacked the essential skills to reach its goal, so it brought in the knowhow it lacked.
One of the best examples of a human-machine hybrid is found in language teaching. It takes around 130 hours to master a foreign language. Recently, Duolingo combined machines and human intelligence by mobilizing 150,000 responders to test thousands of variants of its online language lessons. Thanks to this collective output, it decreased the time needed to speak a foreign language to 34 hours, and that brought them 100 million learners.
The most exciting examples of hybrids are those that combine humans, machines and animals. Peru has used vultures fitted with GoPro cameras and GPS to seek out illegal garbage dumps, supported by a citizen awareness campaign. Chad has fitted dogs with sensors to track diseases, and the UK has used pigeons to observe air pollution.
For a large number of people to think well, smart minds and smart machines are not enough; infrastructure, virtual and physical, is also needed. The plan Richard Chenevix Trench followed to create the Oxford English Dictionary is a model still used today for similar projects.
To publish an empirical, scientific and comprehensive dictionary, it was necessary to read all available literature and gather every use of every word. Trench acknowledged that such a task required “the combined action of many.” He expected 100,000 contributors but was eventually helped by six million, and it took more than 20 years to finish the first part of the dictionary.
The eradication of smallpox is considered one of the world’s greatest successes of collective intelligence. A successful example of collective intelligence is an assembly of different elements whose synergy gives positive results. These assemblies consist of elements such as organizational models that constantly need to be reassessed because they evolve with changing environments.
“There is a need for new assemblies that can marshal global collective intelligence for global tasks, from addressing climate change to avoiding pandemics, solving problems of unemployment to the challenges of aging,” writes Mulgan.
The subject of collective intelligence brings to mind artificial and machine intelligence. Will robots replace half of all jobs in the next two decades? “Labor markets have proven to be dynamic over the last two centuries coping with massive destruction of jobs and equally massive creation too. There is no obvious reason why a much more automated society would necessarily have fewer jobs,” writes Mulgan.
If we are willing to spend money on smart robots to help or drive us, that will increase the status of what is not automated. This is happening now. Designers’ craft is in demand. Handmade is trendy. And if you want it, you must pay for it. An automated society cannot survive if it consists only of consumers and no workers.
But Mulgan acknowledges that the great drive for new intelligent machines today is driven by military and intelligence agencies, and the development of new intelligent tools to monitor the environment or improve our health still lags far behind. “Creating such tools on a scale, and capabilities proportionate to the challenges, and nurturing people with skills in ‘intelligence design’ will be one of the great tasks facing the 21st century,” he writes.

What We Are Reading Today: The Wind-Up Bird Chronicle
- Murakami’s prose, understated yet richly evocative, guides readers through a narrative that oscillates between the real and the surreal
Japanese novelist Haruki Murakami’s “The Wind-Up Bird Chronicle” is an intricate, mesmerizing novel that weaves together the ordinary and the surreal, creating a tapestry of existential questions, hidden truths and unexpected journeys.
First published in 1994, the novel is often regarded as one of Murakami’s masterpieces, encapsulating his signature blend of magical realism, psychological depth, and cultural introspection.
At its heart is Toru Okada, an unassuming and somewhat disaffected man whose mundane life takes a sudden and dramatic turn when his wife, Kumiko, disappears. What begins as a straightforward search evolves into a labyrinthine journey, leading Toru to confront not only the mystery of Kumiko’s absence but also the darker forces of history, memory, and his own psyche.
Along the way, he encounters an eclectic cast of characters, each with their own enigmatic role to play in the unfolding story.
Murakami’s prose, understated yet richly evocative, guides readers through a narrative that oscillates between the real and the surreal. The novel’s structure mirrors this duality, as Toru navigates his increasingly strange reality while descending into dreamlike underworlds, mysterious wells, and symbolic landscapes.
These moments are imbued with Murakami’s distinctive sense of unease, where the boundaries of the tangible and intangible blur, leaving the reader questioning the nature of reality itself.
One of the novel’s great strengths is its ability to juxtapose the deeply personal with the historically and culturally significant.
While Toru’s story is intimate and introspective, it is interwoven with threads of Japanese history, particularly the atrocities of the Second World War. These historical narratives, told through the recollections of various characters, deepen the novel’s scope, turning it into a meditation on the lingering wounds of the past and their impact on the present.
“The Wind-Up Bird Chronicle” also delves into themes of connection and alienation, power and vulnerability, and the search for meaning in a world that often feels inexplicable. Toru’s journey is not just a physical quest but a spiritual and emotional odyssey, forcing him to confront the unseen forces that shape his life and the lives of those around him.
Murakami’s use of symbolism and recurring motifs — cats, wells, and the titular wind-up bird — adds layers of mystery and interpretive richness to the novel. These elements, coupled with the novel’s nonlinear structure and surreal interludes, create a reading experience that is both immersive and disorienting, drawing readers into a world that is as unsettling as it is beautiful.
For longtime fans of Murakami, “The Wind-Up Bird Chronicle” is quintessential, showcasing the author’s ability to blend the banal with the extraordinary. For new readers, it offers an expansive introduction to his universe, though its complexity may require patience and reflection.
Ultimately, “The Wind-Up Bird Chronicle” is a profound exploration of the human condition — its mysteries, its contradictions, and its quiet beauty. It is a novel that refuses to offer easy answers, instead inviting readers to embrace its ambiguities and immerse themselves in its layered, dreamlike world. Murakami has crafted a story that is as haunting as it is enlightening, leaving an indelible mark on those who dare to journey into its depths.
