As we meander through our daily routines, we are surrounded by numerous messages and people trying to get our attention and convince us to do something. We sign into our e-mail accounts and are bombarded with sales pitches to help us get rich quick or promise to fix all of our embarrassing physical problems. We drive to school and see billboards touting tantalizing restaurants or pitching local political candidates. We converse with our friends and family about current events like the crazy car thief who tried to avoid the police by driving down train tracks right into an oncoming train. Throughout all of these exchanges, we must constantly strive to make sense of the message and determine which are true and which are not true.
