With SMS rings, slide the screen to see "XX Group held a large celebration of the thirtieth anniversary, your phone number to get 20 million award ......" "old school, I drove out of the accident, quickly sinks to 10,000 in the field XX Bank ...... "Do not roll your eyes, delete messages, and then secretly Fu Fei: why crooks also made so mentally out of such information?
[A, from the "Nigerian Prince" Speaking]
Email in English, the most popular spam is the "Nigerian Prince", the story is generally several Nigerian officials put huge amounts of money to "state secrets" in the form of transfer abroad, need to use your name and bank account transfer success after you will get millions of dollars in 10% as a reward. If after promise and these "official" cooperation, over a period of time will be a liar to the ground things are not going to let you to advance little "trivial" tipping fees and RBI officials paid several times the money, the other becomes without a trace.
This trick began circulating a letter in the paper, and then by fax, e-mail and then later, has several decades of history, described as "enduring." Because of constantly being falsely in the name, the Nigerian government in 1991 had published a statement there is no such thing, but this message is still very popular today.
Why is this writing is not smooth, you can search the Internet to e-mail has also been used by crooks. Why do not they write some vivid, lifelike new version?
[Second, according to the set sensitivity loss]
In answering this question, we first look at the fire alarm barking. Sirens often generate two errors: 1, should not be loud when chaos ring (positive error false positive) 2, when the sound does not ring (negative error false negative).
For alarms, if not fire when chaos ring, the loss is not, but it does not really have to play a role in the fire, it will cause huge damage to property and even life-threatening, on balance (loss cost size), the fire alarm increase the number of sensitivity, preferring it to chaos ring several times just in case.
But there are circumstances to reduce the sensitivity. In court, if the evidence against the suspect is not adequate, the court also made two errors: 1, the bad guys into good guys wrong (false positive) 2, the bad guys as good guys put a (false negative).
Also compare the losses caused by two cases, if a good person is guilty of misjudgment, this injustice even if only a few plays, it makes the court's credibility is greatly reduced compared to temporarily let go of a bad loss is much greater. Therefore, most countries will adjust sensitivity lower than, this is called "the Conflict (reasonable doubt)".
[Third, why crooks still in a mentally handicapped information? ]
For the liar, the goal is to find the exact user (dupe) in the vast sea, and the quality of the e-mail equivalent of "sensitivity", will first part of the crowd of people might be fooled screened. So the crooks will mistake is:
1, false positive: the crowd would have been no gullible people to catch up, and carry out fraud.
2, false negative: I missed the crowd of people silly naive, did not deceive them.
If the "Nigerian Prince" written messages like Sherlock Holmes detective novels leak, equivalent to increase sensitivity, false positive becomes large, false negative becomes smaller, which means people need to contact the liar becomes more (labor costs increases, customers minimize precise), but in the end really fooled people who do not pay will increase the number. So liar deliberately reduce the sensitivity of fishing, it made a number of false information, so taken were some "silly" of the victims.
[IV trick Review:]
The reason why scammers also send Mentally information, taking into account input costs, output and profits, in order to obtain more accurate victims, the smart people excluded, deliberately release flawed information.
I do not know aerobic or funny, we would have to target not the liar!
