问题     It turns out you can size up personality just by looking at a person’s Facebook profile. While that may not seem like a big deal, it is providing fodder for academics who are trying to predict temperament based on the things we post online. If such predictions prove accurate, employers may have good reason to poke around our Facebook pages to figure out how we would get along with others at the office. And Pentagon officials want to use personality assessments to make better decisions on and off the battlefield.
    A recent study by researchers at the University of Maryland predicted a person’s score on a personality test to within 10 percentage points by using words posted on Facebook. " Lots of organizations make their employees take personality tests," said Jennifer Golbeck, an assistant professor of computer science and information studies at the University of Maryland. "If you can guess someone’s personality pretty well on the Web, you don’t need them to take the test. "
    Golbeck and her colleagues at the university’s Human-Computer Interaction Lab—where she’s the co-director—surveyed the public profiles of nearly 300 Facebook users this year. They looked at users ’ descriptions of their favorite activities and membership in political organizations. They also looked at Facebook’s public "About Me" and "Blurb" sections.
    The 300 participants then took a standard psychological exam that measures the "big five" personality traits: openness to experience, conscientiousness, extroversion, agreeableness and neuroticism.
    People who tested as extroverts on the personality test tended to have more Facebook friends, but their networks were more sparse than those of neurotics, meaning that their friends were less likely to know one another than were the friends of other Facebook users. People who tested as neurotic had more " dense" networks of people who know one another and share similar interests.
    The researchers also found that people with long last names tended to have more neurotic traits, perhaps because "a lifetime of having one’s long last name misspelled may lead to a person expressing more anxiety and quickness to anger," according to the study. People who tested high on the neurotic scale also tended to use a lot of anxiety-associated words, such as "fearful" and "nervous" , on their Facebook posts. They also use words describing ingestion: "pizza" , "dish" , "eat".
    Golbeck says she can’t explain that last correlation. "You’d have to get a psychologist on that one," she said. "It could be that people that are neurotic talk more about what they are eating. It could be a deep correlation that we can’t understand on the surface. "
According to the passage, Facebook profiles may______.
选项 A、provide the researchers with figures about personality traits
B、give some hints about the disposition of the employees
C、help Pentagon make decisions on and off the battlefield
D、take the place of the personality assessments
答案B
解析 推断题。由Facebook profile定位至文章首段。该段第三句提到雇主可以figure out how we wouldget along with others at the office，可见他们可以通过Facebook的个人资料对雇员的性情有所了解，故[B]为答案。[A]项曲解了首段第二句中it is providing fodder for academics的意思，Facebook个人资料只能提供分析材料fodder而不是数据figure，排除；[C]项则偷换概念，帮助Pentagon做决策的不是Facebook的个人资料，而是依据这些资料所做的心理评估，故排除；[D]是对第二段最后一句的曲解，原文是说如果你可以根据网上的内容把人的性情猜个差不多的话，那就不需要让他们参与性格评估了，但并不是每个人都有Facebook个人主页，因此宣称Facebook个人资料可以取代性格评估属于过度推断，故排除。
