To ensure a critical point lands and is remembered, first prime the audience's brain for attention. Place a surprising or pattern-disrupting element immediately before your most important message. This creates a cognitive "ready state" for processing and memory.
Creating something truly new (novelty) is difficult. Instead, generate surprise by combining familiar elements in unexpected ways, like a pug hatching from an egg. This works because the brain is wired to pay attention to prediction failures, which is what surprise creates.
Audiences forget 90% of what they hear within 48 hours. To ensure your key point is remembered, you must proactively define your single "10% message" and repeat it frequently. Otherwise, the audience's takeaway will be random, preventing unified understanding and action.
If your message isn't memorable verbatim, your audience retains only the "gist." Over time, their fallible memory will misattribute that gist to the most familiar source in your category. This means you risk spending time and effort creating a message that ultimately benefits your competition.
To control what your audience remembers, verbatim repetition is crucial. Neuroscientist Carmen Simon's research suggests repeating your key message 4 times in 5 minutes, 6 times in 10, and at least 12 times in 20 minutes to overcome the brain's natural forgetfulness, even with sophisticated audiences.
