People posses an uncertain perception about certain situations, which can easily be altered unconsciously by the mind, as discussed by Errol Morris in this biased perception speech.
How an individual deciphers information is based on the type of mindset they have placed themselves in. Morris believes that having a particular outlook prior to being in a situation will influence the type of experience and overall standpoint a person has regardless of outside factors that they will discover, which proves them otherwise.
The interaction between what people see and believe for themselves has a stronger connection than most people would like to believe, according to Morris. The neutrality of vision does not exist, but in fact, people only view the content they want to believe.
