Everyday we encounter things we don’t question and just accept. Things like stop signs: why are they octagons? And fire trucks: why are they red? At first, these things don’t seem significant, but do they give us an inside view on how we see the rest of the world? Take awkward social interactions, for example. How do we know if they're awkward because of race? In this RadioActive podcast, we explore the concepts of implicit bias and social behavior, and how that plays out for different people in everyday life. This podcast was created in KUOW's RadioActive Intro to Journalism Workshop for 15-18 year olds, with production support from Alivia Thrift. Edited by Jenny Asarnow.
