People Forget 90% of What They Learn
Brain Rules: 12 Principles for Surviving and Thriving at Work, Home, and School, by John Medina, is a fascinating read. It’s full of insights that will benefit anyone who’s interested in speeches and presentations.
Here’s something to ponder:
“[Hermann Ebbinghaus] is most famous for uncovering one of the most depressing facts in all of education: People usually forget 90 percent of what they learn in a class within 30 days. He further showed that the majority of this forgetting occurs within the first few hours after class. This has been robustly confirmed in modern times.” (Page 100)
I suspect you could say with equal validity, “People usually forget 90 percent of what they learn in a presentation within 30 days.”
If it’s true, do you try to make people remember more of what you say? Is it enough if they forget only 80 percent or 70 percent? Or do you change what you’re trying to accomplish in a presentation?
