I have had the same problem as George Siemens. "After the presentation, a VP (in charge of training and development) approached me and stated that simple messages are preferable. I assumed this to mean that I had delivered a presentation that was too complex." And I ask with him, "when did leading thinkers in corporate learning conclude that their audience can not handle complex subjects?" or, with even more concern: how is it that our institutions promote people who cannot understand complex concepts to positions of leadership? Isn't that tantamount to mismanagement?
