According to Adam Jones, if a dominant group of people has little in common with a marginalized group of people, it is easy for the dominant group to define the other as subhuman. As a result, the marginalized group might be labeled as a threat that must be eliminated.[8] Jones continues: "The difficulty, as Frank Chalk and Kurt Jonassohn pointed out in their early study, is that such historical records as exist are ambiguous and undependable. While history today is generally written with some fealty to 'objective' facts, most previous accounts aimed rather to praise the writer's patron (normally the leader) and to emphasize the superiority of one's own gods and religious beliefs."[9]
