What really makes the difference in innovation is whether the corporate culture is paying attention to innovation.

Minimization is what happens when we take the "world is flat" idea too far...and act as if people everywhere are the same (and thereby minimizing the differences).

Generating diverse ideas requires being clear about the kind of input needed and creating multiple ways for diverse team members to share their ideas (e.g. use more than just a brainstorming session).

The very ability to empathize with a user requires that I have an understanding of that user's value and needs. This is what leads to many product fails. The individuals developing the innovation don't actually use it.

There are highly innovative companies in the U.S., Germany, and India. And there are many stories of companies that failed to innovate in all those countries. This is good news because it means, regardless of your cultural background or where your company is based, it can become innovative.

Developing an explicit decision-making process upfront for how you will make that decision will help alleviate conflict and gridlock when you actually need to decide.

When you start paying attention to diversity, you notice it (and notice its absence!). And based on the culture of your upbringing and the culture of your organization, you may or may not be primed to think consciously about innovation.
