Every country has a brand, negative or positive, and that brand is mediated in part by its global press coverage. We are measuring and ranking the perceptions of the 20 most populous countries by crowdsourcing those perceptions through a "World News Quiz." Quiz-takers match geographically vague news stories to the countries they think they occurred in, revealing how they positively or negatively perceive them. By illustrating the way these biases manifest among English and Chinese speakers, we hope to help news consumers and producers be more aware of the incomplete portrayals they have internalized and propagated.
