Summary
In this landmark book， Scott Page redefines the way we understand ourselves in relation to one another。 The Difference is about how we think in groups--and how our collective wisdom exceeds the sum of its parts。 Why can teams of people find better solutions than brilliant individuals working alone？ And why are the best group decisions and predictions those that draw upon the very qualities that make each of us unique？ The answers lie in diversity--not what we look like outside， but what we look like within， our distinct tools and abilities。
The Difference reveals that progress and innovation may depend less on lone thinkers with enormous IQs than on diverse people working together and capitalizing on their individuality。 Page shows how groups that display a range of perspectives outperform groups of like-minded experts。 Diversity yields superior outcomes， and Page proves it using his own cutting-edge research。 Moving beyond the politics that cloud standard debates about diversity， he explains why difference beats out homogeneity， whether you're talking about citizens in a democracy or scientists in the laboratory。 He examines practical ways to apply diversity's logic to a host of problems， and along the way offers fascinating and surprising examples， from the redesign of the Chicago El to the truth about where we store our ketchup。
Page changes the way we understand diversity--how to harness its untapped potential， how to understand and avoid its traps， and how we can leverage our differences for the benefit of all。

Thorough explanation of cognitive diversity， mathematically explainedNot a page turner， but a comprehensive， mathematical exploration of the elements of cognitive diversity。 Some discussion of identity diversity。 I felt more could have been explored between the linkage of the two…maybe another book， but the author at least acknowledges the co-dependency。

'Cognitive diversity is the diversity that matters， enhancing the creativity and efficiency of group problem solving; demographic diversity causes group incohesion， "strange results" [like physical violence --Ed。] and group dynamics that create no end of problems。'This book tries to straddle the line between and even reconcile the two diverse diversities， a Sisyphean task other researchers （Murray， Putnam） have shown extraordinarily difficult at best， even under controlled laboratory conditions 'Cognitive diversity is the diversity that matters， enhancing the creativity and efficiency of group problem solving; demographic diversity causes group incohesion， "strange results" [like physical violence --Ed。] and group dynamics that create no end of problems。'This book tries to straddle the line between and even reconcile the two diverse diversities， a Sisyphean task other researchers （Murray， Putnam） have shown extraordinarily difficult at best， even under controlled laboratory conditions （i。e。， impossible）。Page focuses on intellectual diversity （the inverse of an echo chamber） while paying lip service to the multicult and ethnic diversity without actually backing it up （he knows even better than I that it can not be backed up with science， cf。 Putnam， 'E Pluribus Unum'， the Johann Skytte Prize Lecture for 2006）。 His thoughts on intellectual diversity are very good arguments against the partisan echo chambers of politics and the academy。 His work on diverse group problem solving is vitiated though not crippled by failing to take in to account all available evidence and equivocation of terms， as well as discounting or not mentioning alternate hypotheses （e。g。 groups more accurately represent an efficient market when diverse because of paranoia and distrust of other participants， and then insure they're not getting a bad deal - something that spells disaster for society outside of the laboratory）。 Page does convincingly demonstrate that intellectual homogeneity is one step away from groupthink and cripples （or strongly hinders） creative and efficient problem-solving。 Echo chambers slaughter meaningful original thought。 Politicians bait and switch along these lines， substituting racial/ethnic diversity for intellectual diversity， an entirely false equivalency。His conclusions， ironically， avoid， but do not contradict the conclusions of Jared Taylor in 'White Identity'， a book I am reading in conjunction。 However， Page is a primary source and somewhat more transparent than Taylor， who executes a masterful synthesis of both primary and secondary sources - but a synthesis nevertheless， instead of original research （not that grants would be available for Taylor under any circumstances）。A solid two stars。 Four or four and one-half in parts dealing with cognitive diversity and diversity of opinion and belief。 One star in those parts in which Page， consciously or not， stumbles in to other kinds of pluralism， like multiculturalism and enforced 'diversity' （as in 'Department of Diversity and Inclusion'） and acts as an apologist for them。（Pre-Nov 2018 review） 。。。more

Scott Page describes in detail the circumstances in which diversity brings advantages to groups in terms of problem solving and prediction。 Page argues that it is cognitive diversity that brings benefits， though this often can be expected to correlate with identity diversity。 Page is refreshingly hard-nosed about data and mechanisms， and is very upfront about where diversity can be expected to set us back。The mechanism of gains from diversity is worth spelling out in the review。 Page describes c Scott Page describes in detail the circumstances in which diversity brings advantages to groups in terms of problem solving and prediction。 Page argues that it is cognitive diversity that brings benefits， though this often can be expected to correlate with identity diversity。 Page is refreshingly hard-nosed about data and mechanisms， and is very upfront about where diversity can be expected to set us back。The mechanism of gains from diversity is worth spelling out in the review。 Page describes cognitive diversity as differences in perspectives， heuristics， interpretations， and predictive models。 These are ways of seeing the world， data， problems， etc; ways of arranging and clustering data; tools for solving problems; and the models in which we deploy all of the above。 When we have cognitive diversity， we are often able to leverage these differences in productive ways。 Given diverse perspectives， for example， groups avoid getting stuck on problems that are especially tricky for one or another perspective （think of math problems that are especially tricky when rendered in terms of radial coordinates versus Cartesian coordinates）。 And in cases of making predictions， Page shows plausible conditions in which the diversity of a group is just as important as average individual accuracy。 。。。more

you can't let this be the big finale！Some comments on style: I'm glad when academics can write books that communicate well to general， nontechnical audiences。 Too often， however， Page errs on the side of being too-cute and too-clever。 Many times I felt like I was looking in on a Page Family Reunion， and while I'm sure it's a nice family， these inside references take me out of the moment and pointlessly draw attention to Page's personal life and cleverness。 That persona is probably very charming in the classroom; in print， it doesn't work nearly so well。 Now that he has his first-time author giddiness out of his system， I hope the next book will avoid cute inside jokes about most of the 285 （I'm exaggerating） people mentioned in the Acknowledgments （the Acknowledgments which are then followed by a Prologue， which is followed by an Introduction）。Also in future books， Page may not want to name all of his editors （here he lists four）， which then makes the typos and other errors all the more glaring。 Editors may grumble about not getting the credit they deserve （and that's true）， but anonymity is a nice thing when errors abound。 But at least some of the mistakes were entertaining。 On page 202， for example， the “wisdom of crowds” momentarily becomes the “wisdom of crows。” On page 229， 105 waffles transform into pancakes， and then back into waffles。 There are a lot of tables in this book， so inevitably there will be problems with the table data。 One that stood out to me: on page 212， Page's claim about data in Table 8。10 looks incorrect。 Adam Jones's actual number （6） is not in the range between the low （9） and high （16）—unless I'm missing something （which is definitely possible）。 And finally， having lived in Papua New Guinea for a decade， I have to take exception to the mention of “Papa New Guinea” on page 345。 Ouch。 The number of errors in this book should embarrass Princeton University Press。On another， fairly insignificant， side note for Princeton University Press: I like nicely designed book covers， and I like it when they make sense and have something to do with the content they envelop。 So I've been puzzled every time I pick up The Difference， trying to figure out why on the front cover part of two of the letters in the word “Difference” are yellow while the rest of the word is red。 And why， when the title is written again on the back cover are those letters entirely， not just partly， yellow？ My toolbox is apparently not diverse enough on its own to come up with the underlying logic of this cover。 。。。more
