The National Center for Biotechnology Information has estimated that the human attention span dropped from 12 seconds in the year 2000 to just 8.25 seconds in the year 2015. Speaking from personal experience, I’m sure there are plenty of things that have held my attention for far longer than that.
But absent anything else that really interests me at any given moment, 8.25 seconds actually sounds about right. Assuming this is what we have to work with, it's unlikely that anyone is going to pay more attention to us simply because we ask them to. Instead, we’ll probably need to give them something more compelling to pay attention to.
One way to capture people’s attention is to engage them in the fine art of storytelling.
