Sean Turnbull and Bart Sibrel discuss how it’s possible to fool most of the people most of the time by keeping all but a few hoax perpetrators in the dark:
It isn’t difficult to grasp once you understand that human cognition is not percipient of all things at once (a continuum), but at best, several things added together (a summation). When you’re fleeing from predators, it’s to your advantage to simplify (sum up). But this may not be advantageous when you’re being rubed by a con artist.
Cinderella’s understanding of how this works is limited, but think of it this way. If we can be fooled optically (see this web site), then just imagine how easily we can be fooled cognitively.
