Liberals are Losers
... in the political wars, at least recently.
Haidt plots importance of five "morality modules" against position on the political spectrum from very liberal to very conservative and finds a striking result. Only two of the modules (care, and fairness) are very important to the most liberal, and their importance declines with relative conservatism, while the other three (loyalty, authority, and purity/divinity) increase with increasing conservatism, until all are of essentially equal importance to mainstream conservatives.
This fact says Haidt, gives conservatives a built in advantage in that they can appeal to all five of our these root moral modules.
