Conventional sociology tends to reproduce rather than resolve social injustice. Rather than perpetuating that odious tradition, in this article the author proposes a remedy for racism. Sociologists often sneer at “activist” science of this nature. However, scientists in other fields tend to agree with Karl Popper’s (1999) conviction that good science is an exercise in problem solving. The authors argue that sociology can finally become relevant by attacking social problems the way that medical researchers attack cancer.
