Steve Rathje has managed to rack up more than a million followers on TikTok (@stevepsychology) while pursuing a PhD in social psychology (and doing some very cool research). He shares quick videos about key insights from psychological science that are reaching an entirely new audience. In our conversation, he fills me in on the finer points of TikTok as a platform, why it's uniquely suited to science communication, and how Steve approaches each video to bring insights from social science to a largely untapped audience.  This episode is part of a special podcast series on science communication.
