Civilpolitics.org has a mission to use rigorous science to help others, including politicians, to get along. The mission is "to help you find academic scholarship that illuminates the causes and consequences of political civility and incivility." And here's more, from the "Moral Psychology" page:

At CivilPolitics, most (but not all) of us believe that direct appeals to people to behave civilly will have very limited effects. We take a more social-psychological approach to the problem of intergroup conflict. We are more interested in legal, systemic, and policy changes that will, for example, change the ways that the "teams" are drawn up (e.g., in elections), and supported (e.g., financially). We want to change the playing field and the rules of the game, in the hopes that players in the future (citizens as well as politicians) will be less likely to demonize each other, mischaracterize each others' motives, and refuse (on moral grounds) to engage in negotiations, interactions, and cooperative enterprises that would serve the nation's interests.

Check out the "Social Psychology" page, which contains this advice (with lots of explanatory links).
