There is significant discussion as to whether athletes should be considered role models.[12] Some athletes have been asked to behave as if they were role models for their local communities,[13] and some such as Hank Greenberg have deliberately tried to set a good example[14] but generally regarding athletes as role models has been criticised due to their appointment often being based solely on sporting ability rather than any morality[15][16] – it has been suggested that the discipline and control shown continuously by sportspeople on the field leads to a belief from viewers that these same qualities are continuously shown off the field. These and other factors such as the elements of competition, excitement and success are what make people want to emulate them.[17] Charles Barkley has stated that he believes athletes are not the figures that children should be emulating and that it is the parent's responsibility to be role models,[13] that the role is deliberately applied by the media out of jealousy in order to make life more difficult for sportspeople, and that it sets up the sportspeople as an unattainable target for most.[14]
