An amusing and interesting project from the Gapminder Foundation, which aims to eliminate ignorance with a fact-based worldview that everyone can understand.
The Ignorance Project started in order to investigate what the public know and don’t know about basic global patterns and macro-trends. They use surveys to ask representative groups of people simple questions about key-aspects of global development.
As the project evolves it will investigate many countries and questions. Results are freely available under Creative Commons Attribution License.
