One evening in February 2007 . a student named Paula Ceely brought her car to a stop on a remote in Wales . She got out to open a metal gate that blocked her path . That's when she heard the whistle sounded by the driver of a train.Her Renault Clio parked across a railway line. Second later,she watched  the train drag her car almost a kilometre down the railway tracks.

     Ceely's  near miss  made the news because she blamed it on her GPS device(导航仪).She had never driven the route before .It was dark and raining heavily . Ceely was relying on her GPS. But it made no mention of the crossing ."I put my complete trust in the device and it led me right into the path of a speeding train ,"she told the BBC.

   W ho is to blame here ? Rick Stevenson ,who tells Ceely's story in his book When Machines Fail US, finger at the limitations of technology. We put our faith in digital devices, he says,

      but our digital helpers are too often not up to the job. They are filled with small  problems. And it’s not just GPS devices: Stevenson takes us on a tour of digital disasters involving everything from mobile phones to wireless key boards.

     The problem with his argument in the book is that it’s  not clear why he only focuses digital technology,while  there may be a number of other possible  causes. A map-maker might have left the crossing off a paper map. Maybe we should blame Ceely for not paying attention. perhaps the railway authorities are at fault for poor signaling system. Or maybe someone has studied the relative dangers and worked out that there really is something specific wrong with the CPS equipment. But Stevenson doesn’t say.

It’s a problem that runs through the book. In a section on cars, Stevenson gives an accout of the advanced techniques that criminals use to defeat computer-based locking systems for cars. He offers two independent sets of figures on car theft; both show a small rise in some parts of the country. He says that once once again not all new locks have proved reliable. Perhaps, but maybe it’s also due to the shortage of policemen on the streets. Or changing social circumstances. Or some combination of these factors .

The game between humans and their smart devices  is complex. It is shaped by economics and psychology and the cultures we live in. Somewhere in the mix of those forces there may be  way a wiser use of technology.   

If there is such a way, it should involve more than just  an awareness of the shortcomings of our machines. After all, we have lived with them for thousands  of years. They have probably been fooling us for just as long .

If you ask Americans whether or not they think their former president George W. Bush is smart, most of them will probably tell you they don’t think so. However, Bush’s IQ score is estimated to be above 120, which puts him in the top ten percent of the population.
It doesn’t seem to make sense. How come someone with such an IQ score is not considered smart? Researchers say: IQ does not tell the whole story. Some people have high IQ scores, but still they can be poor thinkers and decision-makers.
Keith Stanovich, a Canadian professor of human development and applied psychology, has been looking into the “clever fools” phenomenon for 15 years. He says IQ tests are very good at measuring certain mental faculties(能力), including logic, learning ability, working-memory capacity (how much information you can hold in mind), etc. Those faculties play a part in one’s academic success, but rational thinking is more important for us to make good judgments in real-life situations.
IQ tests fail to work when it comes to rational thinking. That’s because they are unable to assess things such as a person’s ability to weigh up information, or whether an individual can set aside the cognitive biases(认知偏差)that may be misleading.
“A high IQ is like height in a basketball player,” says David Perkins, who studies thinking and reasoning skills at Harvard University. “It is very important, all other things being equal. But all other things aren’t equal. It takes a lot more to be a good basketball player than being tall, and it takes a lot more to be a good thinker than having a high IQ.”
