Second, terrorism, more than any other form of warfare, has an impact on a target group immensely larger than that of the immediate victims and often on populations beyond that terrorism bears primarily on individuals’ perceptions, on the "public mind"; in other words, it is a form of psychological warfare.

[单项选择]Study after study has shown what has come to be known as an "empathy gap" in people. In its simplest form, this means that when we are happy we have trouble identifying with someone who is sad, or when we’re angry we have difficulty understanding why someone is content. Basically, our ability to empathise with another person is dependent on the state we ourselves are in, and this has some interesting implications for public policy.
A recent study by Loran Nordgren of Northwestern University’s Kellogg School of Management, Mary-Hunter Morris of Harvard Law School, and George Loewenstein of Carnegie Mellon University, examined the empathy gap with regard to torture policy. Man’s propensity to turn monster has long been of interest to behaviourists and psychologists. Witness Philip Zimbardo’s prison experiment, or Stanley Milgram’s shock experiment.

1 Life satisfaction, which can be defined as general happiness or well being, is related to several demographic and personal qualities. The factor of age is important because the elements that make up life satisfaction may differ from one age to the next. Income is more likely to predict life satisfaction among middle aged and older adults than among young adults. Health is a more significant predictor of happiness among older adults than among the young or the middle aged. However, average levels of life satisfaction do not change significantly with age. Generally speaking, older adults are as satisfied with their lives as are younger or middle-aged adults.
