While reading the great little book “Advice for a young investigator” by Santiago Ramon y Cajol, Nobel laureate 1906, I stumbled upon a quote the author attributed to another Spaniard, Perez de Ayala: “Look at things as if for the first time”. Somehow, this quote sent me back in thought inside the conference room where the scientist presents. There sits an audience looking at a slide for the first time. The presenter, however, may have been looking at it more than ten times, during its creation, revision, rehearsal, and presentation. Nothing is new. It is simply a slide to explain – in its broad lines.
The audience is puzzled. Why does figure A not quite overlap figure B? The title claims both findings agree… Is the presenter making things look better than they are to force conviction? Naturally, the presenter knows that the reason for the slight discrepancy is noise in the data; therefore, the conclusions stated in the slide title stand firm. But the audience is not told. Had the presenter looked at things as if for the first time while rehearsing, had the presenter probed every inch of the slide for all the possible questions the visuals could raise among the non-experts in the audience, such discrepancies would have been highlighted and explained during the talk. Naturally, that requires time, and less can be presented. But less is more. What the presenter buys in exchange for the loss of slides is credibility and authority.
My advice to the scientist who presents is to look at each slide as if for the first time while rehearsing, and let that rehearsal time be the presentation time. I would trade off time for clarity and authority, any time, at all times 🙂
