When plain folks do heroic things
(HealthDay) -- The Sept. 11 terrorist attacks raise a particularly poignant question about human nature: Why would some people respond with heroic displays of altruism to save people they don't even know?
Why people give up their own lives to save others, even strangers, is a complex question, says one expert in this ABC News story.
The American Psychological Association has weighed in on the arguments over whether altruism is the result of nature or nurture. Meanwhile, British scientists say they've disproved the notion that some animals are naturally altruistic, says this BBC News story.
