What is the author's style in The Bell Curve: Intelligence and Class Structure in American Life by Richard Herrnstein?

The perspective of the Bell Curve is - notoriously for some, and heroically for others - unabashedly conservative/libertarian. The authors affirm the values of individual responsibility, merit-based social institutions, bourgeois virtues, unbroken homes, limited government and free markets. They also emphasize innate biological features of human nature and recommend that society accept natural inequalities between the abilities of individuals rather than attempt to deny or repress them.
