Haidt is much better psychologist than political philosopher, and this book is both monumental and dangerously flawed.

On the good side: Haidt draws broadly from research in psychology, anthropology, and biology to develop a six-factor basis for morality (Care/Harm, Liberty/Oppression, Fairness/Cheating, Loyalty/Betrayal, Authority/Subversion, Sanctity/Degradation), and show that moral judgement is an innate intuitive ability accompanied by post-hoc justifications. Morality serves to bind non-related groups, i.e. society, together, and moral skills have been favored by various evolutionary mechanisms over human history. This theory is, frankly, really good and really well developed.

Haidt then goes on to show that Liberalism draws from only the first three moral factors while Conservatism draws from all six. This explains both the differences between liberals and conservatives, and why conservatives beat the stuffing out of liberals at the polls. This is also incontrovertible.

But Haidt is unwilling to follow his theory to its ultimate question: Can a democratic political system that privileged the rights of the minority procedurally sustain decision-making based on all six moral factors? Care/Harm, Liberty/Oppression, and Fairness/Cheating are universal factors; everybody uses them, and we mostly agree on when they are upheld or violated. Loyalty/Betrayal, Authority/Subversion, and Sanctity/Degradation are intrinsically provincial factors; they're different for every culture, and every individual.

A moral order for a pluralistic society which takes the latter three factors seriously must either force people to uphold a morality they do not believe in, or segregate people based on their different interpretations of morality. Perhaps I'm particularly sensitive to such concerns because I'm a liberal Jew, but forcing false beliefs on and/or ghettoizing people seems profoundly wrong. Conversely, giving a Moral Minority the ability to gum up the works whenever they feel their rights are under attack is killing good governance.

Where conservatism fails is that we are no longer living in separate communities. It's one global economy, one atmosphere, one water cycle, one oil supply, etc. Haidt faults liberalism for damaging American moral capital in the 60s and 70s, but he doesn't explain how conservatism can become big enough rule the globe.
