Future Savvy: Quality in Foresight

There’s an interesting Information Week article Google Tracking System Suggests Swine Flu Is Spreading posted yesterday (April 29) that investigates the possible predictive power of Googling (human search) activity, suggesting increased searching / monitoring of swine flu on Google could be predictive of rising levels of infection. Google says country-specific (Mexico) data for 19-25 April shows a spike in flu searches.

Google introduced “Google Flu Trends” (US) in November as a way to visualize correlation between flu infections and flu-related searches. It maintains search levels provide early warning of flu spread because search data can be gathered and analyzed almost instantly, unlike traditional epidemiological reporting methods. (More on the goal of the project is in a post on swine flu on the official Google blog.)

The predictive power of Google spikes is hardly clear. Yes, a spike could suggest increased levels of infection. But it could be cause by media coverage and rising levels of pandemic concern.

Google predicts “no pandemic”

More broadly, however, the Google search phenomenon, and information saturation that goes with it is, I believe, highly predictive in epidemic situations. It predicts they are very unlikely. Generally, knowledge is power. Specifically deep and easily searchable public knowledge of where the epidemic is, and what to do to avoid it, and avoid spreading it, is a new condition in human history, one which in fact reliably predicts that no pandemic will happen. Yes, strains become more virulent and dangerous and even drug resistant, and yes, airlines transport it around the world in hours. But the power of knowledge in the labs and in the public at large is immense and ubiquitous in a way it never was before.

One of the debates in futures studies is how much and in what way to look at the past as a guide to the future. Paul Saffo says: look back at least as twice as far as you are trying forecast, and I agree with that. In thinking about a major modern global health epidemic our minds are in fact deeply conditioned by a 90-year-old event: the 1918 Influenza Pandemic that killed an estimated 50 million worldwide. In that epidemic there were particular conditions, not least four year of devastating war where more were lost to disease than fighting; associated drain on resistance and infrastructure; and forced mobiization of troops under poor conditions, that greatly facilitated the spread of the disease. Most importantly, ordinary people were operating in a knowledge vaccum that is unimaginable today.

This is not to say that we should not be vigilant and prepared. But the future that we most likely face is many-and-regular outbreaks like the swine flu, the avian flu, and so on, which we will move fairly quickly to contain. The dystopia of world pandemic is appealing to the health crisis community and its service providers, but the future will not be history (1918-1920) repeating itself.
