Man is a Measure

9). When Bruce saw an actual living rhinoceros and how dissimilar it was from Durer's model, he still made it the same this is because it wasn't how he had always imagined they would look.
11) What you think before you see something, what you have been trained to believe is what you re going to affect your perception of things. This could mean that all studies should be conducted as a double blind study so that the researchers expectancy and researcher bias does not affect the outcome of the study itself. 

deception and truth telling

I think that deception is generally bad but I agree with the statement that sometimes lying is not morally debilitating if no harm is done "white lies". Lying is necessary for the area of knowledge called knowledge by description. When people are describing things to other people or teaching them about it then sometimes deception is necessary. Like the artist who staged the photo to teach people how things would normally look, he was being honest about what he had seen but he was using deception when he said that the photo was accurate. Plus when people describe things that tend to embellish to get a point across which could be another form of deception.
