Positive attributes are judged to be more descriptive of themselves than of an average person, whereas negative ones are judged to be less descriptive of themselves than of an average person.[6] Despite the fact that it is statistically impossible for most people to be superior to their peers, rather than being equally aware of ones strengths and weaknesses, people are more aware of their strengths and not very aware of their weaknesses. This effect has been widely recognized across traits[7] and abilities[8] including the different abilities of driving,[9] parenting,[10] leadership, teaching, ethics, and general health. This effect is also evident in memory; most people also tend to perceive their ability to remember as better than it actually is.[11]
