We like to think we're open-minded and objective because it makes us feel good about ourselves and of course, nobody wants to be seen as closed-minded, biased or unteachable. But in a world where we all have pre-existing beliefs, ideas, values, likes, dislikes, biases (yes, even you), preferences, programming, standards, perspectives and opinions, is it possible to be truly open-minded, even if we want to be?
