A fascinating study, authored by Samuel Sommers of Tufts University, examined decision making in diverse groups compared to non-diverse groups in a jury setting. He put together 29 mock juries of 6 people each; half of the juries consisted entirely of white people, and the other half of 4 white people and 2 African-Americans. Apart from the ethnicity, the jury selection was randomized. Each jury was then presented with a video of a trial with opening statements, witness testimony, forensic evidence, and closing arguments.
What was notable about the findings was how decision making differed between all-white and diverse groups. In deliberating, diverse groups discussed a greater breadth of information than non-diverse groups. Diverse groups also discussed more of the facts in each given case, and when evaluating the facts, were less likely to make factual errors. And when it came to looking at what information was missing from the presentations of the cases, diverse groups were more likely to examine this missing evidence.
Interestingly, the largest area of difference between these groups was that white jurors behaved differently – considered more facts and a wider view of the cases – when they were deliberating in a diverse group than when they were part of all white groups. It is encouraging that the exchange of information was greater in diverse groups. But what is even more fascinating is not just that the amount of information being passed around was greater, but that the bringing together of diversity created a “chemistry” of deeper thinking within the group. It would be fair to say that the group was smarter when it was diverse. And it is important to bear in mind that what these groups were talking about was detailed and complex. They weren’t guessing how many jelly beans were in a jar, they were weighing up a complex set of evidence, with missing pieces of information, to come to a challenging conclusion. In other words, they were dealing with situations that reflect the real world.
The study begins with a quotation from Thurgood Marshall that summarizes the effect of diversity in decision making groups extremely well:
“When any large and identifiable segment of the community is excluded from jury service, the effect is to remove from the jury room qualities of human nature and varieties of human experience, the range of which is unknown and perhaps unknowable. It is not necessary to assume that the excluded group will consistently vote as a class in order to conclude, as we do, that its exclusion deprives the jury of a perspective on human events that may have unsuspected importance in any case that may be presented.”

What is the difference between implementing diversity and activating diversity, and why should I care?
It is not enough to have a spectrum of demographic characteristics within an organization’s workforce. To bring about the advantages and benefits of having a diverse group of people in your company, you must actually do something. That something is activation.
Activating diversity begins from the notion—popularized by James Surowiecki, Cass Sunstein and others—that a sufficiently large and diverse group of people will generally produce better decisions than a non-diverse group, a group of experts or an individual. The implication of this startling idea is that it allows for an entirely new approach to promoting diversity in an organization. With this new mind-set, diversity ceases to be an uphill struggle to change behavior, and instead becomes a process of taking advantage of dormant or underutilized assets within the organization: its latent diversity. Activating diversity is that process.
Implementing diversity means having a diverse mix of people within the organization. If you’ve implemented diversity, you are diverse and you are filled with the potential for great things to happen, for the power of diverse-group decision-making to take place in your organization. Activating diversity is what you do to bring that about, to fulfill that potential. Implementation is planting the seed. Activation is water and sunlight.
Implementation is pretty well understood by people in the diversity business: recruitment, promotion, retention and so on. Activation is far less understood because it is often assumed that if you put the ingredients together, if you implement diversity, then the magic will happen. This is not necessarily so.
Activating diversity, on the other hand, requires an environment where diverse groups are employed as a decision-making engine, a built-in resource for managers who want to take advantage of the wisdom of crowds.
First, it requires educating people within the organization about how and why diverse groups are better at making decisions. Second, it requires creating processes for accessing group opinions within the company, for finding out what the diverse group thinks. Fortunately, once the education is achieved, these processes are likely to emerge naturally so long as people are encouraged and allowed to participate in decision-making activities.
Activating diversity also requires an inclusive environment that sincerely welcomes all opinions. Within that environment, people are being asked to offer up their best qualities, their best ideas and their most creative selves. It is the antithesis of the keep-your-head-down culture in which hiding yourself behind a curtain of adequate competence is the norm. Activating diversity asks people to give more of themselves and in return offers true participation in the life of the organization.
Happily, activating diversity fits in well with existing diversity programs since most such initiatives are geared toward creating an inclusive environment. A workforce that is already familiar with the precepts of an inclusive workplace is particularly well-primed to understand and accept the power of diverse groups to generate better decisions.
A nice quick description of Kluster, the latest of several companies which attempt to organize, formalize, and monetize crowdsourcing for companies looking for innovation from outside their own workforce. Probably the first of these companies was Innocentive, which was started up by Alph Bingham, a very clever fellow who, among other things, pioneered prediction markets at Eli Lilly’s eLilly division with great success. Cambrian House and Idea Crossing are two other players in the crowdsourcing business.
Each of these organizations takes a somewhat different approach to creating a crowdsourcing model, and differ quite markedly in style. Innocentive comes across as the most grown-up of the bunch, corporate friendly, and seems to have the longest track record, although this is a very new field and it remains to be seen how things will shake out. Kluster, the subject of the NYT article, is the most youthful, not surprising as it’s founder is 21 years old. Their website, though certainly well put together, has a bit of a skateboard aesthetic, especially when the young man in the wool cap makes his cameo.
For all its limitations - a lingering sense of unreliability being foremost - Wikipedia has been a remarkable success story. Who would have thought, when it began, that an encyclopedia written by anyone who felt like adding their two cents would turn out to be as accurate, not to mention greatly larger in scale, than Britannica. But is it an example of the wise crowd at work? Chris Wilson at Slate argues that it is not, and that “chaperones”, an elite group of uber-contributors, dominate.
The problem with Wilson’s argument is that it is based on one statistical calculation, the meaning of which is not at all clear. That statistic says that 1% of Wikipedia contributors make about half the edits on the site. What we don’t know is how many people that 1% constitutes. If it’s 10,000 people, that’s a pretty large crowd. We also don’t know what kind of edits that 1% of contributors is making. There is reason to believe that much of it is administrative and grammatical rather than content-altering in nature. Meanwhile, much more than 1% of contributors are making the other 50% of edits.
The Slate article reveals a misunderstanding of the wise crowd phenomenon. To gain the benefit of the crowd’s wisdom requires a large and diverse group, but not necessarily every single person who makes an edit on Wikipedia. Even taking the 1% stat (which was itself arrived at with questionable methodology), if that comprises a large and diverse group, then the phenomenon will likely work.
