Final answer:
Negative stereotypes of outgroups would be considered a legitimizing myth in social dominance theory.
Step-by-step explanation:
In social dominance theory, a legitimizing myth refers to a belief or narrative that justifies and maintains the existing social hierarchy and inequalities. Out of the given options, negative stereotypes of outgroups would be considered a legitimizing myth.
Negative stereotypes of outgroups serve to reinforce the dominant group's power and privilege, as well as to maintain the subordination of the outgroup. These stereotypes create a false narrative that justifies the unequal treatment and discrimination faced by the outgroup.
For example, if a dominant group holds negative stereotypes about a particular racial or ethnic group, it reinforces the belief that the dominant group is superior and the outgroup is inferior, justifying the unequal treatment and discrimination.
