Want to know why?

Our brains are hardwired for specific types of content.


90% of the information we take in comes to us through our eyes.1


Stories are relatable, which is why they make up nearly 2/3 of our daily conversations.2


Two-way conversations help “sync” our brains in a process called neural coupling.3

How can this help you create more engaging, persuasive, and memorable presentations?

Be more engaging

In this on-demand age of smartphones and ubiquitous wi-fi, presenters have to fight harder than ever to grab and keep their audience’s attention.

Visuals are more engaging—and work faster—than words.

It only takes about 1/4 second for the human brain to process and attach meaning to a symbol.4

By comparison, it takes us an average of 6 seconds to read 20-25 words.

How can this affect your presentations?

We can’t simultaneously read and listen.

“When people think they’re multitasking, they’re actually just switching from one task to another very rapidly.”5

Earl Miller, MIT Neuroscientist

We hear stats. We sense stories.

Studies show metaphors and descriptive words activate our sensory cortices*, engaging our brains more completely.6,7

*This is easier to achieve when not focused on reading slides.

Fast fact

70% of marketers say interactive content is very effective at engaging their audiences.8 Try some simple interactions during your next presentation and see for yourself.

Be more persuasive

Studies confirm the persuasive power of stories. People are more likely to relate and react to your message when you engage them on a human level.

Creating an emotional connection can have a big impact.

For example, which is more compelling?

Little Rokia’s parents were killed in the war and now she lives in desperate poverty and hunger. Won’t you please give a little to help Rokia eat tonight?

The storytelling bias

A Wharton Business School study found that people donate twice as much when presented with relatable stories than with statistics alone.9

In Africa, drought has resulted in widespread hunger for more than 3 million children. Won’t you please give a little to help relieve the food shortages?

TIP: Combining stories with your stats makes your presentation both relatable and credible.

What are some other ways to make your presentations more persuasive?

Seeing is believing.

Presentations using visual aids were 43% more persuasive than those without.10

“Include me!”

The top 2 habits of successful sales people, according to their customers:11

1. They educate me with new ideas or perspectives.

2. They make me feel like we’re collaborating.

Tip time

By making your audience feel like you’re working together toward a common goal, you build trust and rapport.

Be more memorable

Neuroscientists and psychologists have known for years that the way a message is delivered can help make it easier to recall.

We tend to recall things in terms of spatial relationships.

For example, think of what’s in your kitchen.

Chances are you mentally “looked” around your own kitchen at home and recalled where objects sit in relation to each other, rather than created a mental bullet-list of items.

Using spatial relationships

Memory champion Nelson Dellis remembers complex lists by picturing the various items in different locations within his home. Get creative!

“The brain works better in pictures. A lot of the information we encounter every day is abstract. If you associate it with a picture, it’s easier for the brain to latch onto."12

Nelson Dellis, Memory Champion

What other techniques can you use to be more memorable?

Picture superiority effect

Ideas presented graphically are easier to comprehend and remember than those presented as words.13

Memorable interactions

Twice as many consumers say interactive content is more memorable than static.14
