In a TEDG­lobal 2012 talk given in Edin­burgh, Scot­land, Cuddy outlined her research, offering a “free, low-tech life hack that takes two minutes” as part of “Your Body Language Shapes Who You Are.” Almost everyone will acknowl­edge the impor­tance of non-verbal, inter­ac­tive commu­ni­ca­tion. We make big deci­sions based on such infor­ma­tion, and often do so in a heart­beat: whom we hire, whom we go out with, whom we vote for, and the like. We take it as a given that others’ stances, gestures, and non-verbals matter to our experience—and that ours matters to others.
