From the TED site:
"It may seem that big problems require big solutions, but ad man Rory Sutherland says many flashy, expensive fixes are just obscuring better, simpler answers. To illustrate, he uses behavioral economics and hilarious examples."
There is great fodder for thought here vis-a-vis performance improvement. The big solutions are not always the best (e.g. training is often not the best solution to a performance challenge). Good front-end analysis and a presumption of no budget creates an opportunity for creative problem-solving and good design. Learner control over the process (unlock those navigation controls!), immediate & private micro-feedback (automated?), and an eye to behavior change science (motivation, skill, confidence as pillars) are thoughts that flashed across my mind as I watched this presentation.
Forewarning: The beginning doesn't seem particularly relevant, but when you get to the "lentil" story, you've hit the sweet spot of the presentation.
