Effective Variant on the Assertion – Evidence Paradigm

The Assertion – Evidence paradigm, promoted by Michael Alley, does indeed force the presenter to limit the information on each slide (and less is mostly more, even in scientific presentations – see limitations). But does Assertion follow Evidence, or Evidence follow Assertion as in the traditional scientific order? To determine which order is more effective, I seeked the opinion of the scientists in the audience during my communication skills seminars. Some do not care about the order. But some prefer to see the evidence before an assertion is made – particularly if a question is raised prior to showing the enlightening visual evidence. When asked to probe this visual evidence for answers, their mind leaves the passive show-me mode to enter the active let-me-see mode. They are more involved and interested. When they discover the yet-to-appear assertion by themselves, under the friendly guidance of the presenter, they are more likely to be convinced by it and more likely to remember it when it is revealed.

Food for discussion.

Here is an example:
