Race is real because we perceive it. Racism is real because we enact it. But the appeal to science to strengthen racist ideologies is on the rise - and increasingly part of the public discourse on politics, migration, education, sport and intelligence. Stereotypes and myths about race are expressed not just by overt racists, but also by well-intentioned people whose experience and cultural baggage steer them towards views that are not supported by the modern study of human genetics. Even some scientists are uncomfortable expressing opinions deriving from their research where it relates to race. Yet, if understood correctly, science and history can be powerful allies against racism, granting the clearest view of how people actually are, rather than how we judge them to be. HOW TO ARGUE WITH A RACIST is a vital manifesto for a twenty-first century understanding of human evolution and variation, and a timely weapon against the misuse of science to justify bigotry.

种族是真实的，因为我们感知到了它。种族主义是真实的，因为我们制定了它。但是，以科学来加强种族主义意识形态的呼吁正在上升--而且越来越多地成为关于政治、移民、教育、体育和智力的公共讨论的一部分。关于种族的陈规定型观念和神话不仅被公开的种族主义者所表达，而且也被一些善意的人所表达，他们的经验和文化包袱引导他们走向现代人类遗传学研究所不支持的观点。甚至一些科学家在表达他们的研究与种族有关的观点时也感到不舒服。然而，如果理解正确，科学和历史可以成为反对种族主义的强大盟友，给予人们最清晰的看法，而不是我们判断他们是如何的。如何与种族主义者争辩》是二十一世纪理解人类进化和变异的重要宣言，也是反对滥用科学为偏执行为辩护的及时武器。
