Presenting science to an audience of peers is among the most fundamental of job skills. Yet, few scientists receive training in how to present, beyond the occasional ad hoc critique during the weekly lab meeting, or the odd rehearsal leading up to a thesis defense.
If you've ever experienced a really good presentation -- and you have -- you know that the average quality level of presentations at conferences is abysmal. Too often, they're little more than data dumps, with no clear story line or explicit scientific conclusion. If you want to know how the data presented alter the scientific landscape, you'll have to fill in the blanks yourself because most presenters don't do it for you. It doesn't help that the ubiquitous format -- a series of bulleted PowerPoint slides -- isn't good at demonstrating subtle relationships among complex ideas.
It's not surprising that most talks aren't very good. Giving a good talk requires a combination of skills that, as already noted, are not taught. A good presenter must be both visual designer and performer. She or he must prepare well and then perform under pressure.
