A tendency toward self-deception is part of our makeup and enhanced our fitness in interactions with others in groups. If we believe our own stories, then we are much more convincing when we tell our stories to others. Also, a bias toward over-estimating our own abilities can keep us striving for that which is just beyond our current reach.
