Gina Trapani built a data driven web app that displays the pay disparity between men and women, called Narrow the Gapp. It uses stats from the Bureau of Labor and Statistics by job class. A very simple design with built in sharing functionality that makes the point.
All that data that we’re collecting and using, what does it all mean? It requires context and a human element. An excellent TEDx talk by Jer Thorp.
Competitions, where all things being equal, brings out the best results. Nine players on a baseball diamond work through nine innings against nine other players. Open bidding for contracts in response to a proposal to meet a business problem puts companies against each other for the best solution.
Kaggle is a competition market where players (yes, they call participants players) build the best predictive data model for a problem. In one case, individuals created a model to predict auto collisions nearly 3.5 times better than Allstate’s own models. An ongoing competition is seeking to predict health care admittances. That’s powerful stuff.
