Stories & science; belief and knowledge

noun_1011170We talk about Storytelling a lot at TLF.

Finding ways to tell better, more compelling, more persuasive stories is essential if you want to achieve difficult, long term, goals such as culture change or improved Customer Experience.

Good stories touch people emotionally, link their day to day decisions with an outcome that means something to them, and persuade them to make change happen.

Stories are deceiving

But stories can also be dangerous. We find narratives so compelling that we rush to invent stories to explain any fact, statistic, or research finding. Nassim Nicholas Taleb calls this the “Narrative Fallacy”, and data science expert Kaiser Fung reserves a whole category of posts on his blog for what he calls “Story Time“.

Our ability to weave simple explanations for complex, often random, series of events means that the stories we tell ourselves have a feel of inevitability, in hindsight. As Daniel Kahneman suggests in the classic “Thinking, Fast and Slow“:

“…the ultimate test of an explanation is whether it would have made the event predictable in advance.”

So, if making up stories to account for the data we have is flawed, how do we make sense of the world? Science.

Science (a word derived from the Latin scire, “to know”), has developed over centuries as a systematic method for learning about the world. The scientific method is designed to minimise the impact of our cognitive biases, from making up stories to only noticing things which confirm our beliefs.

Rigorous analysis is the only way to learn robust truths about the world. Every time you (or someone else) come up with an explanation, challenge yourself by asking how you know. If your story is robust, you should have been expecting the finding before you saw it.

Science to learn, stories to teach

Should we give up on storytelling, given that we’re so prone to be misled by it?

Absolutely not. Once we have learned a fundamental truth about the world (through science), we need to communicate that insight to other people. We need to get their attention, persuade them to believe us, and convince them to change what they do.

Too often, in society and in organisations, we see arguments won by people with a simple story over those trying to explain a much more complicated truth. If we want to learn about the world, and use that knowledge to make better decisions, we need to learn to tell better stories with a firm foundation of science at their heart.

On my Data Presentation and Infographics workshop I use this graphic to summarise what I believe the job to be:

We need the care and objectivity of a scientist to learn important truths, the flair of a graphic designer to engage people’s attention, and the craft of a storyteller to communicate and persuade people to change.
