In this episode of Talk Nerdy, Cara is joined by her old high school pal, psychologist and science communication expert Dr. Asheley Landrum. They discuss why a large portion of the public doesn't believe the scientific consensus on topics like climate change, evolution, vaccines, and COVID-19. From pseudoscience to conspiracy theories to extreme denial of reality, Asheley dives deep into the distrust of authority, political propaganda, and psychosocial pressures that lead to belief in "alternative facts."

In this episode of Talk Nerdy, Cara is joined by science reporter Zach St. George to talk about his book "The Journeys of Trees: A Story About Forests, People, and the Future."
