Convincing with a scientific presentation is of great importance, of course, but how does one convince with impoverished slides from which all complexity has been removed for the sake of being understood by non-experts in the audience? So, if convincing data is not around, what takes over the role of data?
Then, there is the matter of time: a scientific talk at a conference rarely exceeds 20 minutes with Q&A. What should we convince the audience of, given such a short time?
Our French guest on this podcast, Dr. Pierre Boulet, professor at Lille University (Sciences and Technologies), is also Vice Head of the Laboratoire d’Informatique Fondamentale de Lille (LIFL). I interviewed him in his office during the summer of 2010 . He gives his perspective on the art and the manner of “convincing”.
Looking at yourself from the perspective of the audience is a real eye opener!

In her book We Shall Not Fail the granddaughter of Churchill comments on her grandpa’s speaking skills. Here are sentences that are of immediate value to the scientist who presents.
“[…]strike when the voice or pen is hot.”
If you have just published a paper, or better, before you submit it for publication, find any opportunity to present its contents… to your peers, to your group. Don’t wait for the invitation, arrange the talk. Your pen is still hot, may be your paper has reached the final draft stage, and you want feedback. Everything is still fresh in your mind. It is by presenting that one becomes a better presenter.
“The best speakers share a common trait. […]. They never end a speech without asking their audience to rise to an occasion or to meet a challenge.”
Read President Obama’s last sentences of the inaugural address, you’ll find a call to action. But what is the call to action for a scientist? What occasion? What challenge? The occasion of partnering with you. The occasion of commenting on your work. The occasion of financing your work or extending the research scope. The challenge of removing the limitations you faced. The challenge to prove you wrong 🙂 or confirm your findings.
“Becoming a strong speaker, however, is not something to be learned from a book. Leaders need role models.”
Who is your role model? Who presents really well? Find out why. Imitation is the sincerest form of flattery. Ghandi said that. Let their style inspire you. It does not need to be a nobel prize winner. Churchill was inspired by Bourke Cochran, a charismatic Irish American democrat, whose Google hits score less than 600 compared to Churchill’s 24.6 million!
“[Churchill’s] central tenet was simple and applies to nearly all forms of business as well as political communications: find the strongest reason in an argument and marshal all the available facts behind it.”
This also applies to scientific communications. The effect of a drug overdose is similar to that of an overdose of facts and slides during a scientific talk. The audience is in stupor. Focus on only making one point per slide. Do not present all the possible graphs that help you make that point. Use the most convincing one, and be ready to defend it and explain it in the most minute detail – if need be.
