Sleep
Is insomnia really a problem of modern life... or is the struggle for sleep older than you think? It's a common lament: this new world of smartphones and constant connectivity makes it nearly impossible to get enough sleep. But Shakespeare's characters were up all night, sleepwalking, and freaking…
Born With It
Why are we so judgemental about how others beautify themselves? Do you wear eyeliner? Dye your hair? Ever gone under a laser, needle, or knife? When it comes to beautification, how far do you think is too far? And why are there such strong moral overtones to our conversations about where to draw t…
Hate
Why do we hate one another - and how can we stop? How and when does conflict metastasize into hatred? Dessa picks apart the science of hostility, with help from a criminologist who identifies the tipping point between prejudice and hate, and an Israeli psychologist who's studied one of the longest…
Stuff
Why do you have all that stuff? What drives us to get and keep so much stuff - even objects that we rarely, if ever, use? Psychologists working on cortisol levels found that living in a messy or cluttered home may correlate to higher rates of depression and that conspicuous consumption may be affe…

Why do crowds move us? Being part of a crowd can embolden us: we might raise our voices in protest at a march, or snort-laugh more at a sold-out comedy gig. But in the popular imagination, big crowds are often associated with danger - with hysteria and violence. From the Hajj to a heavy metal conc…
Dress Codes
Why do we care so much about what people wear? An etiquette adviser, a civil rights lawyer, and an Iranian activist walk into a podcast studio… Think twice before dismissing fashion as frivolity. Dress codes are about power - and they’re sometimes contentious enough to incite anger, legal battles…
