Just as our brains fill in the details of an image our eyes record only roughly, so, too, do our brains employ tricks we are unaware of to fill in details about people we don't know intimately.

Our subliminal mental processes operate outside awareness because they arise in these portions of our mind that are inaccessible to our conscious self; their inaccessibility is due to the architecture of the brain rather than because they have been subject to Freudian motivational forces like repression.

Every aspect of our lives plays out in two versions: one conscious, which we are constantly aware of, and the other unconscious, which remains hidden from us.
