Tech’s diversity problem isn’t just about the pipeline. Despite good intentions, many companies find increasing gender, racial and age diversity a challenge. Unconscious bias is likely playing a significant role in stifling a diverse workforce. Whether the question is about “culture fit” or “competency,” whether a tiny startup or a tech giant, women and people of color struggle against the invisible power of unconscious bias. By understanding more about our hidden biases, we can develop practices and systems to overcome them and create workplaces filled with teams that are not only diverse, but also inclusive and high-performing.
