We asked respondents to indicate how much control they had over their lives and how optimistic they were about the future, using a scale on which ten indicated a highly optimistic sense of control and one a deep level of powerlessness and pessimism.
我们使用十道能够显示出人们对生活控制到底呈高度乐观还是深度无助和悲观的测试题，要求回答者简单地说明他们可以在多大程度上控制他们的生活以及他们对未来有多乐观。
