Airs Monday, August 6 at 8:00 p.m. Cruelty, violence, badness... This episode of Radiolab, we wrestle with the dark side of human nature, and ask whether it's something we can ever really understand, or fully escape. We encounter a man who scrambles our notions of good and evil, turn to one of the most famous (and misunderstood) psychology experiments ever, talk to a man who chased one of the most prolific serial killers in US history. then got a chance to ask him the question that had haunted him for years: why?
Airs Monday, July 30 at 8:00 p.m. Our world is saturated in color, from the softest hues to the most lurid, violent stains. But it’s hard to put your finger on how something so intangible can have such a visceral punch. This hour, we ask how the pigments around us color our thoughts, and wonder how much of what we see is on the outside...and how much is created in our heads. From Sir Isaac Newton sticking a needle in his eye, to a sea creature that sees a rainbow far beyond what humans can experience.
