Scott presents evidence for the reality and high economic costs of racial and gender discrimination, arguing that fighting prejudice is important and potentially effective. Longer summary

This post argues against Reactionary politics by defending the importance of fighting racism and sexism. It presents evidence from controlled experiments showing significant discrimination against minorities in job hiring, housing, and other areas. The post then estimates the economic costs of discrimination in the US to be at least $438 billion per year, comparable to the costs of major diseases. It concludes that even small successes in reducing racism and sexism could have large economic benefits, and that while many social justice efforts may be ineffective, there is potential for evidence-based approaches to make meaningful progress.
