Perception and Redemption

One of the many problems with perception is that it is notoriously unreliable, and that's why in all criminal cases, corroboration of facts is necessary by deposition in order to present a case to any grand jury.  No matter how impartial any witness might seem to be, his or her perception will be prejudiced.  Everyone perceives differently, but no one perceives accurately.  There is a genetic basis to perception and that basis causes any perceiver not just to see what is happening, but also to see it very narrowly based upon the observer's past experiences.  The result is every observation has to be verified before it can be taken as the truth.  In other words, any observation has to be confirmed and redeemed by experiment and other observations before it could be accepted generally.  Of course, for the individual, in his or her every day affairs, his or her observation is more than sufficient.  That is the difference between opinion and fact.  Everyone has opinions and those opinions are always especially strong on emotional topics like religion and politics, but they are simply opinions.  They can't be considered to be facts.
