Same data, new bottles, clearer messages, and better forecasts

They say a definite cure for romantic notions about any previous era of human existence is to think about the dentistry. That fixes any nostalgia. However it’s safe to say that no one will be nostalgic for all prior eras of working with data which was – when findable (pre-search engines) – a matter of scouring through tables of figures in heavy books.

No longer. The paradigm was broken by the Hans Rosling (Gapminder) video “Debunking Myths About the Third-World,” 2006. By Rosling’s own admission, his analysis is not based on new or better data. The (UN) data has always been there (yes now it’s becoming more available). But the seachange is new software which makes it easy to filter and present it in dynamic, graphic form. And, no surprise, this is popular. According to Gapminder, this video has seen by 500,000 people, not bad for a 20-minute treatise on perceptions of developing world countries.

Data turned into dynamic moving pictures is, one might say, required in our era (trends: visual literacy, short attention span, computing power) so thankfully we can expect more of this. What’s important, for forecast evaluation purposes, is the power of explanation and mental-model challenge that the improved communication provides. As Rosling says of his Swedish graduate students: “Their problem was not lack of data, it was preconceived ideas” (an outdated world view of “1st world” vs “3rd world.”) An endless amount of poring over dusty tables of figures would be unlikely to change that. But it’s hard to watch Rosling’s moving bubbles and not have one’s paradigm shaken.

Another site, in a similar vein, is worldmapper, a University of Sheffield initiative. Worldmapper communicates hundreds of world indicators, from infant mortality to military spending and so on, by manipulating the size of territory of each country to indicate presence or absence of the variable in question, as the following maps show:

Again it is basically UN data that is being sourced, but now presented in a way that cuts through the obscurity tells and the story much more vividly. As we know, humans “get it” better and faster via images than via words or figures. It challenges our perceptions in a way that figures in dusty tables cannot. They payoff is it’s harder to miss what’s really going on. So we have a better view of the world: our mental model aka ‘paradigm” more closely approximates reality. That means we will make better assumptions going forward which will, on balance (no guarantees of course), convert into better predictions.
