Rebel Ideas: The Power of Diverse Thinking

by Matthew Syed

Rebel Ideas examines the power of 'cognitive diversity' - the ability to think differently about the world around us. It explains how to harness our unique perspectives, pool our collective intelligence and tackle the greatest challenges of our age - from climate change to terrorism. It draws on a dazzling range of case studies, including the catastrophic failings of the CIA before 9/11, a fatal communication breakdown on top of Mount Everest and a moving tale of de-radicalisation in America's Deep South. Rebel Ideas will strengthen any team or organisation, but has dozens of personal applications, from the art of personal reinvention to the remarkable benefits of personalised nutrition. It shows us how to become more creative, how to collaborate in a world becoming more interconnected, and how to break free of the echo chambers that surround us all.

Syed deep-dives into 'Rebel Ideas', outlier thinking, showing concisely and clearly with perfect examples like the CIA's failure to prevent 911 and a must-read tale of deradicalization in the Deep South. Syed shows how 'collective intelligence' from a diverse pool, diverse in ways of thinking and/or origin is the most effective way of working. Any team or organisation investing in Rebel Ideas would benefit. Syed gives multiple examples where collective intelligence = making more money! The promotion of diversity and much of its use has been politicised, Syed takes out the politics and brings in the facts and the science in a very accessible way. A must-read! I have no idea how much I needed to read this. A Four Star, 9 out of 12 read for me.

Pushing for diversity is often simply seen as a politically correct move, but Syed stresses how diversity has far greater impacts than we would gather upon first inspection.

First, because we have a tendency to surround ourselves with people similar to us, we form “resonance chambers” which simply reiterate the same old ideas, and result in us making the same old mistakes. With a more diverse team, it’s more likely that you’d have more new ideas, and a reduced rate of error propagation.

Beyond simply improving efficiency, the exposure to new ideas within a diverse group forces us to reconsider the positions we have taken on particular matters, helping us to form more well-rounded opinions. The various factors involved in our upbringing (social, cultural, and so on) ultimately shape the way we think, and this manner of formulating new ideas will vary considerably between individuals. By creating a larger corpus of ideas within a “collective brain” comprising of individuals from different backgrounds, we can potentially increase effective creative output by a significant margin.

Syed also explores a very interesting evolutionary angle to this - his argument is that the human brain evolved in order to take advantage of the inherent social nature of our species. He takes the view that, in order to take advantage of the new ideas, practices and techniques that we were seeing in groups, the human brain needed to become more efficient at learning and replicating these things. He suggests that this drove the vast explosion in the volume of the human brain from the time of the Neanderthals to the present.

It’s a difficulty theory to fully confirm, given the circuitous and somewhat torturous route by which the human brain is thought to have evolved, but it remains a fascinating idea nonetheless.

Rather good... and another great read from Mr Syed. Divided into easy to read topics with real-word (and most importantly believable and well researched) sections, there is a wealth of material here for any field.

The section on recombination is outstanding and which melts perfectly into echo chambers. See how you're being lied to and how. There's also a great conclusion with a small but beautifully constructed piece on unconscious bias.

A great read for anyone!

3.4 / 5

I was a bit sceptical of this book at first, but I got much more into it by the end.

Syed explores 2 key themes: diversity and innovative ideas ('rebel ideas', he terms them). His essential premise is that diversity of thought is key for 'rebel ideas', but he also examines the other key factors that are necessary for innovation. Some of his arguments include:
- Hierarchy is crucial for decision-making. But if a hierarchy is too domineering, there will be too much hostility to new ideas.
- Lots of sociable smart people are more useful than a few isolated geniuses.
- Current dietary advice is insufficient because there is such variety in human biology.

He's got a very easy-to-read journalistic style, which is a bit of a double-edged sword. It means I absolutely flew through this book (not quite literally), and he brought his arguments to life with loads of fascinating examples. But it made some of his more provocative arguments a bit difficult to verify, because he breezed through a few different sources without unpacking any of them in great detail.

I was struck by the contrast with Caroline Criado Perez's 'Invisible Women' (partly because he cites that book more than once, as they cover similar topics). 'Invisible Women' is a bit of a slog to read in parts because of how jam-packed it is with information and data, but by the end you've long since been convinced of her essential arguments. With Syed, I went along with him but I'm not so sure I'll take his word as gospel in quite the same way.

To be frank, this was more of an easy-to-read discussion of interesting examples than a clearly-executed article of persuasion. The book lacks a clear structure to me, and I was often a little confused at the relationship of some chapters to others. It's a bit unclear if he's exploring diversity or innovation, and in the end he does both but neither sufficiently. The academic in me much prefer's Perez's style.

A good effort, but lacking a bit in structure, clarity and academic rigour for my taste.

There are some really good insights, especially on the importance of diverse backgrounds in any team.

[Anthony Kkm · Rating 4 out of 5]

Not as good as black box thinking but better than bounce. For the price, I’d wait to pick it up from a charity shop. Syed is now well-practiced at his style of prose. The central tenant of the book is simple and he uses some good, diverse examples to make his point. Sometimes a bit too loquacious, he makes the same point several times in a paragraph or mini-chapter, before and after giving an example which seems like unnecessary padding. Overall an enjoyable read with some interesting take away points.

[Bakunin · Rating 1 out of 5]

Probably the worst book I've read this year. I found it to a way too long article with strong political views which its author attempted to veil by using some studies as examples. This was a bit surprising as I liked mr. Syeds other book.

[Diana Iovanel · Rating 3 out of 5]

I learnt a lot from this book and it was definitely insightful, tackling a topical subject I care about a lot.
But it could've easily described the same things just as well using a third of the space - it was the repetition of every idea multiple times that made it very hard to finish.

[Fergus · Rating 3 out of 5]

3.5*/5

This is a good book based on a valid premise but let down by Syed's overconfidence in areas beyond his expertise.

I read Bounce a few years ago and found it utterly convincing to the point it changed my worldview quite a bit, so I was excited to get my hands on another one of Syed's books. The core idea - that cognitive diversity (which itself is highly correlated with demographic diversity) leads to better outcomes and that even groups of exceptional people underachieve if they are not diverse, is week explained and evidenced. The first half of the book deals with this, and deals with it well. The segments on recombination and echo chambers are excellent. But Syed branches out a bit, and this is where the book falls flat.

The part about nutrition is quite bizarre - it criticises the field for being based on small sample studies but he makes his point using another small sample study on bread. The chapter after this about human collaboration being the driver of progress is pretty unsubstantiated and full of generalisations and unwarranted conclusions. I do agree with the conclusion, but not based on the evidence in this book. The part about internet browser use and call centres is painful to read.

Syed tries to be a lot of things he is not, which is a shame. He's obviously very intelligent, is a clear and convincing writer, and has interesting analysis to share. But he strays a bit far from his wheelhouse in this book and it shows, which is a shame given how solid the core premises are.


It's also just painful reading fluffy descriptions of the working culture of the CIA as if it isn't a death squad. I'm not interested in the diversity hires they made in their bomb Muslim civilians division and to talk about the culture of the agency without any mention of its crimes is absolutely infuriating.

This makes some sense if you know that Syed is a close friend and advisor of Jeremy Hunt, and this is likely responsible for Matt Hancock's recent claim that the UK cabinet has 'cognitive diversity' in response to being asked why there are no black people at the top of the government. I'm not sure this is the best example to prove Syed's theory

[Sergio Caredda · Rating 5 out of 5]

Un ottimo libro. Troppo spesso la promozione della diversita' passa per concetti legati al rispetto delle leggi, o di un clima di "politically correct" che non sempre giova alle organizzazioni. Syed riesce invece a collegare Diversita' e Performance in una modalita' semplice e accattivante, tracciando un nuovo paradigma del successo stesso dell'umanita' come "intelligenza condivisia" che ha saputo far tesoro della propria diversita'. Ottima lettura anche al di fuori dell'ambito manageriale, riesce a dare veramente una panoramica molto interessante anche grazie ai tanti aneddoti presenti nel testo, che ben illustrano le teorie, e al grande supporto bibliografico e scientifico.

amazing! i learned so much, obviously especially about cognitive diversity but also about the case studies used to explain it. i particularly enjoyed the ‘echo chambers’ chapter. very easy read as well

[Domas Gerta · Rating 5 out of 5]

Really interesting book changing the way we think about success. Showing importance of the collective intelligence over individualistic for innovation as well as complex problems solving organisations. It is also emphasised why diversity shouldn’t be seen as politically correct move but a necessity having a deeper, much greater benefit to organisations and society. Author presents ideas through the real life examples (some are tragic events), thus in some places I felt like reading a thriller.

One of the best books I have read in the past year at least! Truly fascinating, with plenty of food for thought. I found myself talking about points he brings up in many conversations. I think everybody should read this book. I also LOVED Black Box Thinking, also by Matthew Syed. I read it several years ago, and it’s impact stayed with me. Phenomenal.

Felt like this could've been a lot shorter. On Syed's books, I also think this draws a lot of similarities with Black Box Thinking - though I did feel that Black Box Thinking was a lot more tight-knit, and better organized.

Farfetched

A lot of empty theorizing. If it had been based around solid quanitive research, it might be a lot more believable.

[Venky · Rating 4 out of 5]

What connects the tragic Everest expedition in May 1996 that consumed the lives of legendary mountain climbers such as Rob Hall and Scott Fischer, with the 9/11 catastrophe where the CIA choose to adopt a blinkered approach to the many cogent threats and chilling clues that emanated from Osama Bin Laden even as early as in 1996? Is there even a link between these two diverse, albeit tragic events? In a bold and provocative book, “Rebel Ideas”, the Sunday Times bestselling author and co-founder of the charity, Greenhouse, Matthew Syed tackles the issue of cognitive diversity, (or a deep lack of it) that characterizes the fabric of our society. And in this process, he reveals fascinating potentials and probabilities which may be both exploited and overlooked – such as the critical binding threads between two seemingly disparate events.

So here is “Rebel Ideas” summarised in the form of a few key takeaways:

The Curse of “Homophily”

When a group of people glued by the same set of thinking assemble together to solve a problem, they bring to the table a homogenous framework, which while greatly aiding and abetting in arriving at a consensus, might totally fail to identify heterogeneous perspectives. For example, a lack of cognitive diversity in the hiring policies of the CIA (which was mostly Pale, Male and Yale at the time of the 9/11 disaster) might have unwittingly resulted in the ignoring of a myriad of chilling clues that proliferated long before the actual tragedy hit home. For example, as highlighted by Lawrence Wright in his Pulitzer Prize winning book, “The Looming Tower”, clad in spartan clothing and issuing proclamations from within the confines of a cave in the mountains of Tora Bora might have made Bin Laden look not just like a Medieval Luddite, but a comically deranged individual too. But the man was a master strategist. By resorting to such tactics he was only appealing to the sentiments of thousands of Islamic youth to step onto the path of radicalisation, since it was from a very cave during a period known as Hejiraa that the vision of the Koran occurred to the Prophet. Yet Richard Holbrooke, one of the most senior officials under the Clinton regime, exclaimed, “how can a man in a cave out-communicate, the world’s leading communication society?”. As Mr. Syed illustrates, one reason for this myopic view was an absence of diversity in the hiring policies of the CIA. A dearth of Muslim agents within the CIA (who would have been alert to at least some of the messages originating from Al -Qaeda), coupled with the existing homogeneity cast a perception blindness, which in turn led to a tragedy of humongous proportions, that was otherwise, preventable.

Stanley Sedgewick & Bletchley Park

Bletchley Park, a non-decrepit estate in rural Buckinghamshire covered itself in immortal glory when a team of men and women working within its confines managed to crack the Nazi encryption device termed Enigma, thereby shortening the very tenure of World War II by at least 3 years. What made Bletchley Park the legend of lore, was the eclectic mix of people sheltered within. From Alan Turing, one of the greatest Mathematicians of the twentieth century, Leonard Foster, a scholar of German and the Renaissance to Norman Brooke Jopson, a professor of comparative philology, the team at Bletchely Park was a classic example in diversity. Of course rounding off the motley crew there was Stanley Sedgewick, a clerk with a firm of city accountants and a crossword tragic, who had participated in a contest hosted by the Daily Telegraph for tackling a cross word context under controlled conditions.

Constructive Dissent on the Everest

The ghastly tragedy that befell multiple groups of climbers as they attempted to create history on the world’s tallest mountain peak on the 10th of May 1996, highlights the peril of the absence of what Mr. Syed terms as “Constructive Dissent.” Even though many of the climbers in Rob Hall and Scott Fischer’s team were experienced altitude climbers, it was their first shot at Everest. Hence there was an acute prevalence of “dominance dynamics” between the guides and their clients. Such a steep hierarchy, however proved tragic as many vital clues were prevented from being disseminated. For example, when Martin Adams one of the clients, noticed thunder clouds as he inched ever closer to the summit, he knew his team had to get out of there. Adams was after all a commercial pilot with loads of experience with thunder clouds. But still he didn’t speak up because he was low in the chain of the dominance hierarchy.

Echo Chambers, Epsitemic Walls and Information Bubbles

In 1996, MIT researchers Marshall Van Alstyne and Erik Brynjolfsson issued the following warning: “Individuals empowered to screen out material that does not confirm to their existing preferences, may form virtual cliques, insulate themselves, from opposing points of view, and reinforce their biases. Internet users can seek out interactions with like-minded individuals who have similar values, and thus become less likely to trust important decisions to people whose values differ from their own.”

The researchers termed this online fissure and faction formations, Cyberbalkanization.” Mr. Syed illustrates both the concept of an Echo Chamber and its consequences in a riveting fashion by informing his readers about the transformation of the once white supremacist Derek Black. Home-schooled by parents who were the rabid epitome of white supremacist beliefs, Black was insulated from being in the proximity of people nurturing alternative views and was fed continuously upon the fodder of white supremacy. This Echo Chamber from which he led his existence formed an information bubble into which contradicting views were not allowed to penetrate. It took Matthew Stevenson, a Jewish friend with a Yarmulke cap and a series of open discussions about sensitive and delicate topics on race and colour to being down Derek Black’s epistemic walls and transform him from a rabid pro-white propagandist into a fervent anti-racism advocate.

Eliminating Unconscious Bias

Unconscious bias refers to “the way that people are denied opportunities not because of a lack of talent or potential but because of arbitrary factors such as race or gender.” Eliminating such bias would broaden the domain and realm of collective intelligence.

Shadow Boards to promote Diversity

Corporations, with a view to channelizing the benefits of diversity, are actively engaged in a mechanism called “Shadow Boards.” Young personnel lend advice to executives on key decisions and strategies. This technique according to Mr. Syed, “lifts the conceptual blinkers that can attach to age.” In fact Gucci benefited to such an extent by employing this shadow boarding techniques, that its revenues leap-frogged a mind numbing 136% – from 3,497 million Euro in FY 2014 to 8, 285 million Euro in FY 2018

A Giving Attitude

A willingness to offer one’s insight to others; to share one’s perspective and to impart one’s wisdom, in turn accords an opportunity to received, according to Mr. Syed. Empirical analysis conducted by Professor Daniel Levin of Rutgers Business School on the importance of dormant ties also lends further credence to this proposition.

“Rebel Ideas” by Matthew Syed is a thought provoking, insightful and relevant work, especially in an age where independent thinking is obfuscated by the pernicious spread of fake news, authenticity is clouded by disinformation and cohesiveness is marred by a group think of the most malicious breed.

[Cathy Moore · Rating 4 out of 5]

I’m going to hear Syed speak at an event next month, so I was keen to understand a bit more about what he might have to say.
I wasn’t disappointed. This was very readable and accessible. The premise is fairly obvious when you consider it, that there needs to be diversity in thought in order for businesses and institutions to progress and be successful. But as human beings we evidently haven’t seen this in the past, and in many incidences continue to fail to see it in the present.
Definitely worth reading if you have the slightest interest in leadership, business, personal development or psychology.

[Osama Qandeel · Rating 4 out of 5]

As the old saying goes, the whole is greater than the sum of its parts. I enjoyed reading the book; it has many good ideas. It made me think about the correlation of this diversity idea with other related fields like democracy in politics. In other instances, I felt that some of the assumed advantages of diversified groups could be explained by the concept of 'skin in the game,' or at least be complementary to it.

The writer also interestingly drew two possible scenarios of how the modern world can impact us. We could utilize the latest and most modern resources to personalize our treatment for individuals in fields like personalized medicine, education, or diet. But there is another risk that the status of hyperconnection could lead us into closed cycles and get us stuck in echo chambers. Ironically, this contradicts what we would expect from easy connectivity that symbolizes our age. I didn't feel that the writer took a firm stand as either optimistic or pessimistic about the issue. He only points to the importance of diversity.

For me, I consider the diversity the first of two simple steps in the way of innovation and creativity. Diversity will help teams generate more original thoughts and bring unique and innovative solutions to the table. But the second and equally important step is how to filter all those thoughts; this could be the subject of a second book.

[Vanessa Princessa · Rating 3 out of 5]

I read this book thanks to Blinkist.

I am familiar with the topics & ideas expressed in this book from other non-fiction books I’ve previously read, hence the 3 stars.

The key message in these blinks:

In the past, success has been the result of intelligence, skill and commitment. This is still a winning combination of qualities when we’re faced with challenges that we can tackle alone. But the problems we face today are too complex for individuals to handle in isolation. To solve them, we must work as teams. And how we construct those teams will determine whether or not we attain our goals. Demographic diversity isn’t enough to ensure we gain a thorough understanding of each hurdle we encounter; our teams must be cognitively diverse, with each team member contributing their knowledge and perspective in an environment that encourages communication. Only then will we avoid the dangers of homogenized thinking and arrive at truly innovative solutions.

Actionable advice: 

Encourage cross-pollination at your workplace.
Brilliant ideas often happen when employees have chance encounters with colleagues from different departments. Conduct an audit to see if you can find ways to encourage this type of incidental mingling, by reconfiguring cubicles which are closing people off from one another, locating facilities like bathrooms in places where different departments will intersect, or arranging seating so that diverse departments are positioned close together. It may seem inefficient or illogical but it’ll help innovation thrive!

What to read next:

Black Box Thinking, by Matthew Syed.

As you’ve just learned, every team charged with solving complex problems will benefit from diversity on its journey towards success. But even the most intelligent and cognitively diverse team can fail. 
But failure doesn’t have to be a wholly negative experience. In our blinks to Black Box Thinking, you’ll learn how our typical reaction to failure – namely self-justification instead of honest acknowledgement – prevents us from reaching our full potential. Through case studies and anecdotes, Syed shows us that, despite the associated pain and shame, failure is one of our greatest assets.

[Teodora Agarici · Rating 4 out of 5]

I knew Matthew Syed from his articles in the Times but this is the first book I read from him. Due to his journalistic style, Rebel Ideas is easy to read and flows naturally which is a definite plus, especially for a book that falls under the smart thinking/ leadership category.

There are some insightful notes that make you stop and question your own naivety. It is, in fact, a very welcome wake-up call to your own blindness.

I was particularly struck by the idea of collective intelligence in the context of cognitive diversity. Finally, someone that dismantles the myth of diversity by checking off quotas with scientific evidence. Time to understand we all have certain frames of references and we'd risk falling into these perspective blindness and knowledge clustering unless we work with people who think differently and bring as many insights, experiences and thinking styles.

The research is exemplary and the case studies Syed uses are memorable. I often seek books that challenge my personal views - Syed managed to 'prove me wrong' on a number of occasions throughout his book and am beyond grateful for it.

Amazing head start on perspective blindness and goes straight to the point ☝️👉

>> Different experiences yield new perspectives to be shared.

>> Homophily occurs when a group of people with the same experiences and perspectives comes together. But this doesn’t yield results; it is effectively a group of people with cloned ideas.

>> Homophily happens when groups of like-minded people collaborate to solve a problem. Nothing out of the ordinary occurs.

≥> businesses with high ethnic and racial diversity levels are 35% more likely to outperform their competitors in terms of profits.

>>Having too many dominant managers in place who aren’t open to new suggestions can completely destroy communication.

>> Echo chambers cause you to be stuck in a box. Nothing changes, everything remains the same, and your view is static.

[Terry · Rating 1 out of 5]

here is no doubt that cognitive diversity brings in different ideas.

What I am not sure, and, in fact, a reason that I don’t like this book, is whether or not the various incidents cited by the author were a result of the lack of cognitive diversity. In other words, can it be proved that had cognitive diversity been adopted in those incidents, the disasters would have been avoided. If not, it is not good at all to use the incidents as an attempt to illustrate the lack of cognitive diversity was the reason for the disasters.

I hope that other readers can share your views.

[Donall Comerford · Rating 4 out of 5]

I think the book is well written and offers a good insight into many current phenomenon that I found extremely interesting (in particular echo chambers). In addition I liked the fact the book identified many issues or flaws in how we interact but was also optimistic in tone.

[Stoyan Topchiyski · Rating 5 out of 5]

This is the second book I have read by this author after Black Box Thinking. I've read it twice in a row, as I believe it is truly remarkable. The book explores the topic of cognitive diversity in depth and explains why it is so important. The author describes the concepts very clearly and in a uniquely nuanced way. I highly recommend it to anyone who wants to broaden their perspective and clarify the lens through which they view the world. An added bonus is that the audiobook is narrated by the author himself, which enhances the listening experience. Here are my key takeaways from the book:

Cognitive Diversity
It is the ultimate idea generator, far more potent than individual intelligence alone in solving complex challenges and creating breakthroughs. This concept goes beyond traditional measures of intelligence, emphasizing the value of different thinking styles and perspectives.

Homophily & Collective Blindness
Humans naturally tend to surround themselves with like-minded individuals, a phenomenon known as homophily. This inclination can lead to dangerous collective blindness, undermining team success by creating significant decision-making blind spots. Actively seeking diverse perspectives and embracing different viewpoints is crucial for achieving better outcomes.

Frames of Reference
A frame of reference is a structured mental framework that helps us organize and interpret information about the world. It consists of interconnected concepts, definitions, and principles that shape how we understand and process experiences.

Frame of Reference Blindness
This cognitive trap occurs when we are unconsciously trapped within our personal belief systems, past experiences, and ingrained thinking patterns. We remain unaware of the very frame we use to perceive reality, creating an automatic filter that limits our understanding and perspective.

Cognitive Clones
Teams composed of individuals sharing identical frames of reference risk becoming intellectual echo chambers. Different ways of thinking and approaching problems are far more valuable than individual brilliance when solving complex challenges. True group wisdom emerges from a combination of intellectual capability and varied perspectives.
Simply replicating top performers can limit the range of problem-solving approaches and potentially missing crucial insights. This reduces the team's ability to innovate and adapt

The HiPPO Effect & Dominance Hierarchies
HiPPO (Highest Paid Person's Opinion) describes a decision-making approach that prioritizes the viewpoint of the most senior team member over data-driven insights. This practice can create dangerous situations where team members feel unable to voice concerns or share alternative ideas.

Innovation
Innovation thrives on cognitive diversity, manifested through:
Organizational Level: Deliberate exposure to diverse networks of people
Individual Level: Multidisciplinary learning and cross-domain knowledge

Standardization vs. Individualization
Individual differences demand personalized approaches rather than one-size-fits-all solutions. This can be expressed as a fundamental principle:
Individualization > Standardization

Knyga kaip geras, savalaikis priminimas, kad žmonių įvairovė yra kūrybos, inovacijų ir bet kokio progreso pamatas.

Kaip sako autorius, problemos, kurias sprendžia šiandieninis verslas, mokslas ir valstybės institucijos, vis sudėtingėja. Vienas žmogus, kad ir koks protingas ir gudrus bebūtų, jas išspręsti nepajėgus. Tam kuriamos komandos, kurios padėtų suvokti klausimo kompleksiškumą, pateiktų daugiasluoksnes įžvalgas ir priimtų geriausią sprendimą.

Jei taip atsitinka (o atsitinka pernelyg dažnai), kad tokią tipinę komandą sudaro "klonai" - vienodų demografinių bruožų (lytis, amžius, kilmė etc.), vienodo mąstymo, pažiūrų žmonės - net jeigu visi jie atskirai paėmus bus įžvalgūs, tokia komanda bus linkusi į kolektyvinį aklumą.

Mes visi turime mąstymo trūkumų, matome tik dalį visumos. Klonų komandos bėda ta, kad jų mąstymo trūkumai - tokie patys. Jie ne papildo vienas kitą, o tik sustiprina vienas kito trūkumus.

Kitaip sakant, atsiranda pernelyg didelė tikimybė, kad visi atkartos vieni kitų realybės suvokimą ir priims sprendimus su perdėtu pasitikėjimu ir rimtomis klaidomis. Kad "aklųjų dėmių" būtų mažiau, komandą turi sudaryti žmonės, padedantys pamatyti tai, ko nemato kiti.

Kai reikia atlikti itin individualią, vienaveiksmę, lengvai atskiriamą nuo kitų užduotį (pvz. ką nors konkretaus išmatuoti), kitoks mąstymas blaško ir nėra reikalingas. Tačiau susidūrus su sudėtingomis užduotimis, tokia logika nebetinka.

Patiko ši mintis: "Pamatinė homogeniškumo problema - (...) tai klausimai, kurių klonų komanda nepaklausia, duomenys, kurių jie neieško, ir galimybės, apie kurias jie nežino. Kuo sudėtingesnė užduotis, tuo mažesnė tikimybė, jog viskam suvokti pakaks tik vieno asmens ar vieno požiūrio."

Autorius pasakoja, kaip kognityvinę įvairovę komandoje gali pražudyti hierarchinis valdymas, kokia svarbi įvairovė inovacijoms, kaip dėl žmonių įvairovės plečiasi mūsų kolektyvinis intelektas. Analizuojami pavyzdžiai, kaip įvairovės trūkumas prisidėjo prie CŽA nesėkmės sustabdyti teroro atakas, alpinistų žūties Everesto viršukalnėje, kaip įvairovė padėjo karo metu iššifruoti "Enigmą" ir pan.

Patiko dirbtinės dilemos apie "kokybę vs. įvairovę" atskleidimas, nes puikiai parodo, kad tai ne priešingybės, o dvi giminingos kategorijos.

I had initially started this book a year ago and ended up forgetting about it... it started off a little drab and I didn't feel that it was telling me anything new per se. However I picked it up again recently and I am glad I did. The focus is not only on racial diversity, but looks at cognitive, environmental diversity. I enjoyed the anecdotes that Syed used to explain his points, interesting case studies from all industries. Particularly perceptive was the idea that immigrants often bring the most to the table in terms of innovation due to radically different experiences that allows them to think differently.
The most useful takeaway for me was the practical suggestions from companies like Amazon on how they try to maximise the diversity in their teams by making their meeting formats more efficient - I straight away was able to think about how to apply this in my own workplace which I appreciate.

I also enjoyed the explanations of diversity in relation to natural selection vs reproduction, the idea of recombinant ideas and how it is new ideas that make 'big brains', not the other way around.

Overall, not a revolutionary book for myself, but relevant for today in a world where individuals operate as if every move is zero-sum, rather than thinking about the growth and potential for progress through sharing and collaboration.

[Sara Vicente Barreto · Rating 5 out of 5]

I was enticed by this book by Matthew Syed. Each time I thought an example had left it plain and simple for anyone to see the benefits of diversity, yet another one came along to add to it. We all heard the numerous stories that diversity can bring, such as the hiring of someone good at crosswords for the team that cracked the German code in WWII. But the book starts instead with examples of potential consequences of the lack of diversity in places like the CIA pre-9/11 or in an Everest climbing team at the time of one of its biggest accidents on record. Not only the power of diversity but more specifically the power of more diverse thinking and structures that allow for diverse opinions to flourish. It gets your attention from the getgo. It shows that diversity of thought allows companies to be more innovative but it also shows that diversity builds plasticity into people's minds and allows them to really change, from the most unexpected cases.
