Final answer:
Scientific racism served social functions such as justifying racial inequalities and maintaining a racially unequal society, while also strengthening in-group bonds through the ostracism of out-group members.
Step-by-step explanation:
The social functions that 'scientific' racism served include justifying racial inequalities and maintaining a racially unequal society. One example is how slave owners in the antebellum South justified slavery by claiming that Black people were fundamentally inferior to White people. Another function of racism is the strengthening of in-group bonds through the ostracism of out-group members. However, there are also dysfunctions associated with racism, such as the failure to utilize talent in the subjugated group and the diversion of resources to maintain racial boundaries.
