On this episode we talk about the rise of the antivaccination movement in Europe and interview Polish psychologist, science writer and science educator, Tomasz Witkowski, who's the author of two very important skeptical books on psychology: 'Psychology Gone Wrong: The Dark Sides of Science and Therapy' and 'Psychology Led Astray: Cargo Cult in Science and Therapy'. He is also one of the founders of the Polish Skeptic Club and a member of the organising committee of the 17th European Skeptics Congress that will be held in Wroclaw, Poland in September 2017.
