Presentation traps 12 – The trap of the introduction slide

By Jean-luc lebrun

You are certainly familiar with scientific presentation slides that have all the structural signs of the scientific paper they were extracted from (same headings, same figures, etc). After the title slide, you will often found a slide with the title “introduction”, “outline”, “motivation” or  “aims”. Anything wrong?

What is the function of that slide?

Yes, its function is to introduce… but not only that. Its function is make sure that the people sitting at the back of the room listen to your whole presentation. The back-sitters are migratory scientists eager to take flight when the temperature you maintain around your topic drops below hibernation temperatures. And they start packing as soon as they see the frigid outline/motivation/aim/introduction slide. After all, it is faster to read your paper than to listen to it (twice as fast, in fact). So the role of this introduction slide is to intrigue, to hook, to captivate the audience by asking a question that becomes the question of everyone in the audience, a question that will keep everyone awake and attentive for the next twenty minutes while you unravel and answer it. Put your question to your audience in a visual form. Make your motivation their motivation, your problem, their problem. Then, when you reveal your solution, it will be theirs also; what satisfied you will satisfy them.

Background knowledge is rarely captivating. You need better than that to hook your audience. Tell a story, give a compelling example, make whatever you are doing essential to THEIR lives. Do not state commonplace facts already known by all in attendance. State the surprise, the novelty, the anguish, the reward… Forget about the conventional wisdom which is foolishness: it is not necessary to give an outline for any talk that is less than half an hour. Would you greet the friend that comes to your home by keeping him one minute at the doorstep explaining the various rooms he is about to go through before sitting down? Or will you just open the door and let the perfume of that scrumptious cake you baked for her capture her pheromone receptors?

The introductory slide is a teaser tightly connected to your title and your purpose. It entices the audience, and keeps the people in the audience in their seat by riveting their attention on you, and your mouth watering topic. And, oh-by-the-way, The hook slide has no title. Save the electronic ink it would require for your visual.
