After years of optimizing its products for engagement, no matter the costs, Facebook announced today it will “test” changes to its News Feed focused on reducing the distribution of political content. The company qualified these tests will be temporary, impact a small percentage of people, and will only run in select markets, including the U.S., Canada, Brazil, and Indonesia.

The point of the experiments, Facebook says, is to explore a variety of ways it can rank political content in the News Feed using different signals, in order to decide on what approach it may take in the future.
