I think the need already exists. But companies are used to getting by (with huge profits) with engineer-driven products and decisions. The extent to which our technological products and services are engineer-oriented is mesmerizing. Steve Jobs once said something about Apple working at the intersection of technology and liberal arts. It was marketing, of course, but I can't even express how much I agree with this.

Regarding the need for a good grasp of statistics in social scientists, I fully agree. But I think it's something that already exists, up to a point at least. I work in software development with many software engineers around, but I also did a PhD with a strong social sciences background. You would be amazed with how much the guys with psychology backgrounds know about stats and methodology (and how much the common STEM guy doesn't).
