Diversity is best defined in one of two ways. Inherent diversity relates to built-in characteristics, such as age, gender, race, and disability. Acquired diversity is derived from the sum of one’s experiences, such as an appreciation for a foreign culture developed as an expatriate during a professional assignment abroad. The combination of inherent and acquired diversity leads to diversity of thought, unlocking innovations that are inaccessible in a homogeneous working environment. Corporate diversity consultant Selena Rezvani notes, “Diversity of thought yields a kind of positive friction from varying approaches, training, and mind-sets.”
