I acknowledge that our views are shaped by our experiences. As such, the only way to holistically gather the various views (that all may have varying levels of “correctness” or “bestness”) is to include these views in what you gather.
As experiences tend to group themselves in a broad view by a variety of demographical factors (age, gender, race, etcetc), the only way to statistically increase your chances of gathering the various views is to intentionally increase diversity.
As an obviously lame and loaded example. Let’s say you run a business. The target area is S Detroit. Your business is credit assistance in the sense that you help manage people with bad credit/history and get them on the road to a better life. You start your business, and exclusively hire non local white men who have never had a credit score below 800 and come from rich families.
In this obviously loaded example, it would almost certainly benefit you to hire a local with personal experience in having poor credit/etc (or any such combination of better factors) that can relate to and understand the pros and cons of the things your business does from a practical standpoint.
Now scale this to a company the size of McDonalds/Walmart/Amazon in a global marketplace.
