    Choice

    We turn up the volume on the voices in our heads and try to make sense of the babble. On a journey around the country to understand how emotion and logic interact to guide us through our options, we ponder how we get through the million choices and decisions we make every day. Forget free will, some important decisions could come down to a steaming cup of coffee.

How Much Is Too Much?

Turns out, Robert is more impulsive than Jad, and Jad is more analytical than Robert. Shocking, right? Sadly for Jad, Robert's style may help him better navigate the overwhelming number of choices available throughout modern life's expanse of options, which may also lead him to a greater sense of well-being, according to psychologist Barry Schwartz. Jonah Lehrer helps us understand why by introducing us to George Miller's classic paper "The Magical Number Seven, Plus or Minus Two," which explains the ability of the average human to hold about seven pieces of discreet information in working memory at any given time. Any more than that, and, as researcher Baba Shiv demonstrates, our good judgment can be overwhelmed...a problem Oliver Sacks overcomes by allowing himself only limited options and a strict routine.

Overcome By Emotion

Instinct or analysis? Wouldn't things be easier if we could get emotion out of the way and let rational analysis lead? Except that so often, that gut feeling turns out to be right. We explore both extremes. Antoine Bechara, a psychology professor at USC, tells us about the case of Elliot, an accountant who, after having a tumor removed from his brain, became entirely rational. And writer Steven Johnson recounts the powerful grip emotion held over his brain in the years following a frightening event. It turns out we aren't the only ones interested in how the emotional and rational parts of our brains interact to make choices. NPR reporter Mike Pesca talks to Gary Loveman, CEO of Harrah's Casinos, to find out how Harrah's has learned to identify the triggers in casino patrons' decision making processes and use them to create a happier gaming experience, and more loyal customers.

Is Free Will Really Free?

It's scary to think that choice might just be an illusion. Perhaps we are not so in control as we would like to be. In a conversation at the 92nd St Y, Malcolm Gladwell talks to Robert about the common sense of dissatisfaction felt by people required to justify a choice to others before they made it, and he brings up the unsettling idea of priming--that certain stimuli could predispose us toward certain choices or behaviors. Yale psychology professor John Bargh takes us a step further by describing an experiment where researcher Lawrence Williams was able to alter people's opinions without their knowledge using nothing but a simple cup of coffee.
