Seeing and believing are not synonymous, as optical illusions can be rooted more deeply in cultural beliefs. Half of the difficulty with empathy lies in the fact that we can never truly know how others see the world, either literally or psychologically, but as we grow older and more settled in our worldview we tend to assume otherwise.
For decades, studies of how our brains work by neurophysiologists and psychologists have turned up a massive User's Manual that seems to explain how and why we think the way we do. The reason that so many people distrust these findings is that they sometimes tell us unpleasant things about our deepest-held beliefs about who we are.
You have to be consistent in how you present yourself -- to the point where you don't mind being "guilty of repeating yourself." If you abandon the consistency, people will get confused and the perception you are trying to change will get muddied by conflicting evidence that you are just the same as you were.
