On increasing the power of presentations (p cubed)

In Medicine we believe our practice is evidence based and effectual. We review our results, keep abreast of the literature and make changes as knowledge evolves. Most presenters believe the same for their presentations. The majority of presentations directly contradict well established psychological principles, aspire to a level around them only of mediocrity and are almost uniformly ineffectual. Worse than this, we instruct our colleagues to present in the same way.
