Creating Ideas that Influence: Jonah Berger, Wharton

Jonah Berger is on to us.  We're social creatures that,
almost robotically, respond to cues and narratives.  His
work on Contagious and Invisible Influence gets to the heart of
why some ideas and products go viral and others don't and how to
uncover hidden "influence hacks" that shape culture and drive
behavior.
