Researchers spend much of their lives unearthing fascinating facts about how the world works, but that knowledge is typically slow to make it into policies that have a positive impact on society. To address this gap, I organised the Language Science Day of Action (20 January 2017), which brought together members of the local research community to discuss effective science communication with non-specialists. Workshop attendees developed engaging, shareable web articles (e.g. a quiz illustrating facts about the structure of language) and put together pitches to highlight the importance of insights from language science to decision-makers like Members of Congress or local school boards.
