"What makes [you] happy?" When asked this question, interviewees on The Science of Happiness podcast gave varied answers, including "sunny days, no stress, music, and community." This question is one of many explored through the podcast, which is produced by Public Radio International and the Greater Good Science Center at UC Berkeley. The podcast is on a mission to help listeners "learn research-tested strategies for a happier, more meaningful life, drawing on the science of compassion, gratitude, mindfulness, and awe." Hosted by Dacher Keltner, a renowned psychology professor, episodes include conversations, experiments, and special guests that help listeners understand and cultivate happiness in their lives. Topics covered range from "How To" guides such as "How To Be Less Hard on Yourself" (Episode 54) to guests sharing advice on "awkward relationships" (Episode 27) and "express[ing] gratitude" (Episode 32). Since the inaugural episode in February 2018, the series has grown to 5 seasons and over 50 episodes. These episodes are around 20 minutes in length, making it a perfect listen for a short commute. Listeners can find all of the episodes on podcast platforms such as Apple Podcasts and Google Play, or via this link, where they can also read the full transcripts.
