James Q. Wilson, American Politics Then and Now and Other Essays (AEI Press, 2010).

This book “collects 15 essays, most of which appeared initially in The Public Interest, Commentary, and City Journal. They are written for a general audience, not in the sense of being dumbed-down, but of addressing questions of concern to the educated public in a manner free from academic jargon and pretense. Those not familiar with Wilson’s work will discover what it means to bring social-science evidence to bear on important contemporary problems.”
R. Shep Melnick (2010)
