When information is received through the senses, our brain quickly and nonconsciously assesses whether it is relevant or irrelevant to us and then attaches emotional markers (worry, happiness, boredom) to that information</b>
The emotional markers help us to store information in memory; they also reproduce the same emotions when we are subsequently thinking about this information
We have a natural and usually nonconscious tendency to seek out information that supports our self-concept or puts us in a favorable light and to ignore or undervalue information that is contrary to our self-concept
