Story-centered learning: Gather “big data” before hypothesis testing

Reblogged from my ThinkNPC guest post:

In the last half-century thousands of scientists have rigorously studied the causes and risk factors in heart disease, but a single longitudinal experiment has revealed more about this disease than any other approach.

In 1948, researchers began tracking health records from all participants in the town of Framingham, Massachusetts. This was an observational study; they did not formulate causal theories or test specific hypotheses, but simply let nature take its course and observed what happened.

In 1960, they found a link between smoking and heart disease. In 1961, they found a link with cholesterol. And in the coming decades, they also found correlations with obesity, exercise, high blood pressure, hypertension, stroke, diabetes—virtually everything that now matters to clinical treatment.

So why aren’t we in the philanthropy world copying this approach—observing what’s out there and looking for patterns over time?

As a neuroscientist, I have a confession to make. My type have been responsible for propagating a lie they still teach in schools, that scientists always devise a hypothesis and test it in controlled experiments. This is simply not true. The human genome project mapped 3 billion base pairs before understanding what variation in the genetic code meant. human-genome

The drugs you take were “discovered” in massive drug discovery libraries using a screening process that quickly conducts millions of tests, rather than hypothesizing. 

My point is that complex problems cannot be understood from a pre-defined framework; what matters emerges most efficiently from open-ended data collection that is later organised and then studied.

We already create more information every two days than existed in the first two millennia of human civilization, and this pace is accelerating. However, the rate with which we convert all this “information” into useful “knowledge” is slowing down.

all-story-topics-2011It was with this problem in mind that we started the GlobalGiving Storytelling project. We needed to dissociate two requirements: to collect rich information about development in a flexible, easily re-structurable way, and to turn these stories into data so we can interpret and contextualize what we see. We’ve come up with a survey design tool which you can use to do a custom evaluation and compare your results to stories told by others, with the overall aim of helping everyone share knowledge and improve project design. The  approach will save you time but it will also enable you to get more back than you could ever put in.

So why do we use storytelling, you wonder? It turns out that managing this process with metrics, indicators, spreadsheets, and a numbers-only mindset is far more difficult and time-consuming. Narratives and a few survey questions are sufficient to see common patterns emerge from many perspectives.
