...experiments in networked science that are now being done to study everything from galaxies to dinosaurs. These projects use online tools as cognitive tools to amplify our collective intelligence. The tools are a way of connecting the right people to the right problems at the right time, activating what would otherwise be latent expertise.
Why don't scientists share? If you're a scientist applying for a job or a grant, the biggest factor determining your success will be your record of scientific publications. If that record is stellar, you'll do well. If not, you'll have a problem. So you devote your working hours to tasks that will lead to papers in scientific journals. Even if you personally think it would be far better for science as a whole if you carefully curated and shared your data online, that is time away from your "real" work of writing papers. Except in a few fields, sharing data is not something your peers will give you credit for doing...
In the years ahead, we have an astonishing opportunity to reinvent discovery itself. But to do so, we must first choose to create a scientific culture that embraces the open sharing of knowledge.
