The researchers looked at how people's beliefs about authority and social dominance affect their prejudice towards different ethnic groups. They found that those who value social cohesion and stability tend to be more prejudiced against groups they see as socially threatening, while those who prioritize ingroup superiority tend to be more prejudiced against groups they see as potential competitors. The study showed that the effect of valuing social cohesion on prejudice was stronger when the outgroup was perceived as socially threatening, but the effect of valuing ingroup superiority did not increase when the outgroup was seen as competitive. These findings suggest that different factors influence prejudice towards different types of ethnic groups.
