There are plenty of good reasons that society is focusing on diversity these days. We’ve come to understand that bias is a sneaky thing, quietly, almost invisibly, skewing our judgment, and—though some biases are helpful—it frequently stands in the way of our treating others as we’d hope to be treated. In the workplace, it leads to hiring discrimination that turns away those who don’t belong to a favored demographic, depriving them of opportunities and leaving companies without the benefits of their talents. In life in general, as well as in hiring, it also causes us to undervalue, overlook, and even fear those who are different. We can best defeat these destructive biases by actively embracing diversity as a shared goal.


Doing so is not without controversy, though, and recently two terms have become central to our societal discussion of diversity. They sound similar, but they mean two very different things:

About neurodiversity

The term neurodiversity was coined by Harvey Blume in a 1998 article about the prevalence of autistic workers in Silicon Valley, according to Emily Y. Liu, writing in The Routledge Handbook of Neuroethics. Since then, it’s become a concept promoted by autistic self-advocates looking to change the view of autism from a pathology to simply another form of diversity.

Liu cites Josef Garen’s list of neurodiversity’s tenets in his 2011 thesis, 'The Trouble With Neurodiversity: Etiologies, Normativity, and the autistic Struggle for Identity':

1. Autism is a natural variation within human diversity.
2. Autism is an integral aspect of individual identity.
3. Autism does not need to be cured.
4. Understandings of autism should be informed by a social model of disability.
5. Autistic individuals deserve equal rights, appropriate accommodations, social acceptance, and self-determination.

While there’s not a widespread acceptance of the notion of neurodiversity in the medical community, says Liu, neurodiversity underpins autistic self-advocates’ concerns regarding three issues in particular:

Though neurodiversity is typically associated with autism, some, such as Heather Heying, feel it may apply as well to other, less dramatic, neurological differences.


About cognitive diversity

The good

Certainly, the potential for obtaining fresh, varied perspectives from efforts to make a workforce more diverse can be thwarted if those in charge of hiring gravitate to the same sort of people regardless of their demographic attributes. What good is a rainbow workforce of people who all think in lock-step? An appreciation, therefore, of the benefits of cognitive diversity has been on the rise, with some interesting research from Harvard Business Review (HBR) that backs up its value for a company.

HBR studied the cognitive diversity of six teams using an exercise called the AEM cube. As its tasks are completed, an assessment can be made of each team’s strength in:

HBR found “a significant correlation between high cognitive diversity and high performance.” The three teams with greater cognitive diversity completed the exercise faster, while those with less took longer, or didn’t complete it at all, a compelling endorsement for seeking cognitive diversity.

The sketchy

Claims of cognitive diversity—sometimes called viewpoint diversity—have recently been used in response to attempts at correcting the under-representation of minorities and women in Silicon Valley companies. According to TechRepublic, 83% of tech executives are white, and more than 50% of Apple and Google employees are, too. The percentage of women mostly hovers in the 30% range, says Business Insider.

Be that as it may, some in the industry resent corrective hiring practices, and have done so since the 1978 Regents of the University of California vs. Bakke Supreme Court decision that established affirmative action on a national level. In some cases, the promotion of cognitive diversity as a hiring goal addresses concerns of whites, and especially males, that they are the ones being discriminated against.

Perhaps the fullest presentation of the anti-diversity nature of the cognitive diversity proponents was a 2017 Google memo called 'Google’s Ideological Echo Chamber'. Purported to be an even-handed summary of diversity issues, its point of view is quite clear, and it’s laced with troubling assertions. Apple has its own problems, with a now-disavowed 2017 statement from then-Vice President of Inclusion and Diversity Denise Young Smith saying, “There can be 12 white, blue-eyed, blond men in a room and they’re going to be diverse, too, because they’re going to bring a different life experience and life perspective to the conversation.” Smith has since noted her “regret” for her wording in an email sent to Apple employees.

The New York Times recently published an op-ed by Bärí A. Williams decrying the rise in popularity of cognitive diversity. In it she writes:

Employees typically recommend people similar to them in racial identity and gender, so it requires dedicated effort to recruit and hire people who don’t already have identities that match up with those of current employees. Counting up variations of “viewpoints”—however one might do so—won’t achieve that. And, to potential applicants from underrepresented groups, statements about “cognitive diversity” will send an unwelcoming message about a company’s real priorities for inclusion.

The value of diversity

Ultimately, it may be, as evolutionary biologist Heying says, that the success of our species is advanced by the ways in which we’re different from each other. As much as it may cause us to rethink how we view each other and how we hire, recognizing and celebrating diversity is clearly worth it. Our myriad of physiological differences, our perspectives, our experiences, and our cultures, make us just that much more ingenious and unique.
