Why do we sometimes believe things that aren't true or aren't entirely true? Why do we remember things that didn't happen or didn't happen exactly the way we think they did? What factors might contribute to our willingness to change our minds? This podcast, hosted by former journalist David McRaney, is dedicated to exploring the psychology behind our beliefs, biases, and the things that shape them. Each forty minute episode is dedicated to a single issue or question. For example, topics explored in recent podcasts include the "optimism bias" in which we underestimate the likelihood that bad things will happen to us; why fiction is a powerful tool for changing people's opinions; and new research that reveals that access to Google and other search engines can make us feel smarter than we really are. Many episodes feature an interview with an expert researcher, offering listeners a diversity of perspectives. The link included here takes readers to McRaney's blog, which includes a link to all episodes along with transcripts of interviews featured in past shows.
