Which group categorization leads to more pronounced ingroup bias as stated by social identity theorists?

Ingroup bias is a phenomenon where individuals show favoritism and preferential treatment towards members of their own group over those of other groups. According to social identity theory, one key factor influencing ingroup bias is the composition of the group itself.

Homogeneous groups, which consist of members who share similar characteristics or backgrounds, often lead to stronger ingroup bias. This is because such groups reinforce a sense of identity and solidarity among members, making them more likely to view their own group positively and other groups negatively. The similarity within these groups creates a strong social identity that prompts members to align closely with each other and perceive any external group as different or less favorable.

In contrast, minority groups may not exhibit the same level of ingroup bias since they often feel marginalized and have less power within a broader social context. Majority groups might be expected to display ingroup bias as well, but the effect can vary depending on societal dynamics and the presence of competing identities. Polarized groups typically refer to groups that have opposing views, which can also heighten bias due to their adversarial nature, but this does not inherently demonstrate pronounced ingroup bias as described in the context of homogeneous groups.

Therefore, homogeneous groups contribute more to a pronounced ingroup bias, as their shared
