Clay Christensen of Harvard Business School has been pushing innovation for years. Now he has come up with “five habits of mind” that characterize “disruptive innovators,” his breed of choice: associating, questioning, observing, networking, and experimenting. “But can innovation be learned?” you ask rhetorically (“Think Different,” August 6, 2011). Well, the above five habits of mind can surely be learned. And by way too many. This is hardly a guarantee for innovation, though. Or creativity, another habit of mind cherished by Christensen. In other words, he will need to dig deeper. Once he could tell us precisely how disruptive innovators think and feel, as well as act in the business world, the requisite habits of mind could certainly be learned. The trouble is that this would leave us with the disruptive innovators already among us. As you suggest in your conclusion, learning to be Steve Jobs would not get you very far.
