Galileo allows anyone to design, review and run an experiment with participants around the world. During the design phase, creators can design experiments based on their intuitions. They are taken through an easy to use and scientifically valid method for designing an experiment. During the review phase, creators can invite reviewers to critique their experiments using open-ended comments and answering specific rubric questions. During the run phase, creators can invite participants from around the world to join their experiments. Participants will receive either automated emails or texts instructing them on the task they are to complete. Once completed, results for the experiment are compiled and emailed out to participants and the creator.
