In a world that expects the wit of Jimmy Fallon, the wisdom of a TED talk and the visual stimulation of Snapchat, giving a PowerPoint presentation with complicated graphs and bullet points sheds about as much light as a birthday candle in a coal mine. If you can’t give a straightforward, dynamic and passionate presentation you should stay home because you are wasting your time and turning everyone in the audience against you.
And don’t give me that crap about the need to cite references and give detailed explanations.
A video of Canadian Prime Minister Justin Trudeau explaining quantum computing went viral. He did it in 35 seconds. A few days later a university professor said on CBC radio that Trudeau did a pretty good job.
You probably already know the difference between a great and a horrible presentation. It’s the difference between being held hostage for 20 minutes at a boring meeting versus 40 minutes of thoughtful bliss as a speaker paints evocative words and ideas that make you forget about checking your cell phone. It’s passion, not a 20 data point chart that gets you excited.
A presentation is not a peer-reviewed paper. It is not a university thesis. It is not an engineering stress test report. It is not a learned legal opinion. A presentation is a conversation and an exchange of ideas between you and an audience. If the presentation is done well, it will entice the audience to seek out and discover more about the topic.
Most importantly though, a presentation is not a document. If you are printing out your slides to leave behind as a hand-out you’re doing it wrong. Think about this: If people can read the printout (in about five minutes) and get what your point is then why the hell did they spend 20 minutes listening to you?
When you’re speaking, the only thing on a screen behind you should be a visual that supports what you’re saying. If there are words on the screen, the audience will read them and stop listening to you. Several studies have shown that comprehension and retention plummet if you put words on a screen and then read them to your audience.
Professor John Sweller has been studying teaching methods for more than a dozen years and says that when the audience has its attention split between what you say and what they read they are less likely to remember anything. Professor Richard Mayer reached a similar conclusion; that listening to spoken narration without text on a screen increases understanding by 79%.
Stories will always be more compelling than a chart of facts and figures. Just ask any kid at bedtime.
