Nothing is going to stop us!

What do you do when someone you really like insists on behaving in a way you can see is dull, unproductive and generally a waste of time and energy?

I feel that about people who use PowerPoint. For the past 10 years I’ve been warning people of its flaws. I’ve been gently and tactfully suggesting to our clients that the psychological evidence is pretty damning.

The American military see PowerPoint as an “internal threat”, because the danger of it creating the illusion of understanding. Edward Tufte the academic and visual-presentation expert claims that PowerPoint “facilitates the making of lightweight presentations.” After all how many life-changing TED talks relied on slides? (Ok apart from David Christian.)

Last week in a workshop a colleague and myself put PowerPoint to the test. First we asked them why they used PowerPoint, all the answers were about their needs (to remember what to say, to provide a structure and because the audience expected it.) No one mentioned the audience and their needs.

Then we carried out an experiment. We took two topics. The first we explained via PowerPoint and the second we asked them to discuss by standing around a flip chart. Two hours later we tested their knowledge. Nobody could remember a single thing about the PowerPoint but could recall most of what they’ve discussed.

So why is PowerPoint so ineffective? Simply put PowerPoint can prevent facts from being placed in our long-term memory. The combination of text and visuals seems powerful but the presenter is also talking over it and the two things continually distract the brain. PowerPoint can place things into short-term memory but for that data to become part of our long-term memory we need both attention and some kind of “meaning.” Meaning is really context, connection to other things and how it will impact on you.

I find a good presenter and a good story can keep my attention and provide all the meaning I need. PowerPoint does neither.

One of my favourite authors on presentation skills Jon Steel, a man who has won billions of pound of advertising pitches, wrote: “Audiences expect PowerPoint because they have been beaten into submission by it, and because nobody has ever had the courage to question their judgment.”

At the end of the workshop we asked the group if they would now change and stop using PowerPoint and they said “no.”

I sighed and reluctantly gave them some tips for a better PowerPoint presentation:

  1. Think about your presentation before you open PowerPoint. What structure will you use? Why should people care? What do you want the audience to do after your presentation?
  2. Never have more words on a slide than you can have on a T-shirt. Be like Steve Jobs use slides for photos and the odd graph.
  3. Don’t rely on bullet points to create an argument. Let the audience internalise your thoughts in their own world and have a discussion.
  4. Audiences are unable to read from a slide if a presenter is then saying the same words out loud.
  5. Know the difference between a PowerPoint presentation made for projecting, and one made for reading later.
