Some researchers introduce race into the "trolley problem" moral dilemma

The classic trolley problem, in which you have to decide whether to take an action that will save some number of people but kill a smaller number of people, has now been tried with race mixed in.

As it turns out, race is a factor in trolley problems, but not in the way you might think.  Read about the study here.  On average, political conservatives are more likely to sacrifice minorities, while liberals are more likely to sacrifice whites.  Of course, this whole political conservative/liberal one-dimensional axis is a gross oversimplification... I'd be interested to see what specific moral beliefs it lines up with.  I'm guessing that people with more in-group bias and more xenophobia are more likely to sacrifice someone of a different race. 

Side note:  Haidt's research on moral underpinnings of liberal vs conservative ideologies is interesting.
