I have written extensively in this blog about the power of storytelling. See, for example, this post and this post. Stories are typically more memorable than data or facts because they trigger emotions and thus make their appeal to the right side of our brains.
Stories are easier to remember because stories are how we remember. When facts become so widely available and instantly accessible, each one becomes less valuable. What begins to matter more is the ability to place these facts in context and to deliver them with emotional impact.
