The Art of Persuasion
The leaders of most modern countries exploit a powerful political tool - the power of images. These techniques, in fact, were invented thousands
of years ago by the leaders of the Ancient World. But how do politicians actually use images to persuade us - often without us even knowing? How did
they do it thousands of years ago?
Interestingly, and relatedly, did you know that if you include images reinforcing a person's stereotypes, they will completely disregard any
sentiment posed otherwise? So if you write about how awful it is to segregate black people from white people, but include an image of a typical thug,
your message will be mostly ignored.
