You just answered your own question: the real kind, exactly. See title.

This is incorrect; the psychology of leftists is that they prize harm reduction as a value above all others. For the benefit of everyone else reading this I'll explain why leftists don't think this way. It violates their own values.

Jonathan Haidt has an interesting talk on TED http://www.ted.com/index.php/talks/jonathan_haidt_on_the_moral_mind.html on where differences from leftists and conservatives originate from. He shows fascinating graphs from 23,000 people who indicated their ideology and answered some questions on The Morality Foundations Questionnaire at www.yourmorals.org concerning their beliefs. He categorizes individuals along 5 fundamental moral dimensions, the first three of which are heavily entwined with social capital. He says the 5 core dimensions for the moral mind (abstracting from anthropology, neurology, psychology, etc.) are:

1. Harm/care – as a species care a lot about others

2. Fairness/reciprocity

3. In group/out group – only among humans are there large groups that are united together for common purposes, and as a species we self-consciously produce or reinforce tribes (for wars, sports team loyalty, etc.)

4. Authority/respect – often based out of love

5. Purity/sanctity (either with regard to things like sex, or the foods we put in our body)

What's fascinating is that if you chart individuals across parts of the world you find that in all societies, conservatives treat all these five factors as moderately important; liberals however focus almost exclusively on the harm/caring or fairness/reciprocity principles. In most societies, the increase in attention given by Conservatives to factors like Respect, Authority, Order, Purity rises much more sharply than the attention to Caring and Reciprocity falls. Haidt describes conservatives as having a 5-channel moral equalizer.

Haidt notes that Leftists speak for weak and oppressed; they want change and justice, even at the risk of chaos. Conservatives speak for institutions and traditions; they want order even at cost to those at the bottom. Haidt thinks Edmund Burke had it right when he said in the wake of the French Revolution: “the restraints on men, as well as their liberties, are to be reckoned among their rights.”
