Peer Review - A process by which articles are read and evaluated by experts in the relevant field. Every peer reviewed journal has its own group of experts who do this, and they only accept articles that are high quality, support their claims with evidence, and add something new to knowledge about a topic. This process is very rigorous, with only the best articles making the cut.
