问题     Psychologists have known for a century that individuals vary in their cognitive ability. But are some groups, like some people, reliably smarter than others? In order to answer that question, we grouped 697 volunteer participants into teams of two to five members. Each team worked together to complete a series of short tasks, which were selected to represent the varied kinds of problems that groups are called upon to solve in the real world. One task involved logical analysis, another brainstorming; others emphasized coordination, planning and moral reasoning.
    Individual intelligence, as psychologists measure it, is defined by its generality: People with good vocabularies, for instance, also tend to have good math skills, even though we often think of those abilities as distinct. The results of our studies showed that this same kind of general intelligence also exists for teams. On average, the groups that did well on one task did well on the others, too. In other words, some teams were simply smarter than others.
    We found the smartest teams were distinguished by three characteristics. First, their members contributed more equally to the team’s discussions, rather than letting one or two people dominate the group. Second, their members scored higher on a test called Reading the Mind in the Eyes, which measures how well people can read complex emotional states from images of faces with only the eyes visible. Finally, teams with more women outperformed teams with more men. This last effect, however, was partly explained by the fact that women, on average, were better at "mindreading" than men.
    In a new study, we replicated these earlier findings. We randomly assigned each of 68 teams to complete our collective intelligence test in one of two conditions. Half of the teams worked face to face. The other half worked online, with no ability to see any of their teammates. We wanted to see whether groups that worked online would still demonstrate collective intelligence, and whether social ability would matter as much when people communicated purely by typing messages into a browser.
    And they did. Online and off, some teams consistently worked smarter than others. More surprisingly, the most important ingredients for a smart team remained constant regardless of its mode of interaction: members who communicated a lot, participated equally and possessed good emotion-reading skills.
According to the author, the characteristics of smarter teams include all the following EXCEPT ______.

选项 A、the members have relatively equal contribution to the team’s discussions
B、the members have a higher IQ
C、the members have a stronger ability of reading complex facial expressions
D、there are more female members than other teams

答案B

解析 细节题。根据题干关键词定位到第三段。此题可用排除法。根据their members contributed more equally to the team’s discussions可排除A项“团队成员在小组讨论中有比较均衡的贡献”。根据Second,their members scored higher on a test called Reading the Mind in the Eyes,which measures how well people can read complex emotional states from images of faces with only the eyes visible.可排除C项“团队成员有较强的解读复杂面部表情的能力”。根据teams with more women outperformed teams with more men.可排除D项“比其他团队有更多的女性成员”。故B项“团队成员有较高的智商”原文没有提到,符合题干,为正确答案。
