問題詳情：
Search engines like Google make people think they are smarter than they actually are because they have the world’s knowledge at their fingertips, psychologists at Yale University have found. Surfing the Internet for information gives people a widely inaccurate view of their own intelligence and could lead to over-confidence when making decisions, experts warn.
Experiments found that people who had searched on the Internet believed they were far more knowledgeable about a subject than those who had learned by normal routes, such as reading a book. “The Internet is such a powerful environment, where you can enter any question, and you can easily get the world’s knowledge at your fingertips.” said Mattew Fisher, a psychology professor at Yale University. “But it becomes easier to confuse your own knowledge with this source. When people are truly on their own, they would easily get more wrong answers.”
More than 1,000 students took part in a range of experiments aimed at studying the psychological impact of searching on the Internet. In one test, the Internet group were given a website link which gave the answer to the question “how does a zip work” while a control group were given a print-out of the same information. When the two groups were tested later on an unrelated question --- “why are cloudy nights warmer?” the group who had searched online believed they were more knowledgeable even though they were not allowed to look up the correct answer.
“We also believe that the wrong sense of personal knowledge also could be perilous in some areas when people make decisions; in case where decisions have great influence such as important business trade, it may cause millions of losses and even bankruptcy of a company.” Mr. Fisher added.
The Internet is a big benefit in many ways, but there may be some disadvantages that aren’t immediately obvious and this may be one of them. “Right personal knowledge is difficult to achieve, and the Internet may be making that task even harder.”
