A scam is stealing valuables by means of pretending, also know as confidence tricks or swindle.


History

The first known usage of the term "confidence man" was in 1849; it was used by the press during the trial of William Thompson. Thompson chatted with strangers until he asked if they had the confidence to lend him their watches, whereupon he would walk off with the watch; he was captured when a victim recognized him on the street.
Vulnerability to Scam

Persons of any level of intelligence are potentially vulnerable to deception by experienced con artists. Confidence tricks exploit human weaknesses like greed, dishonesty, vanity, but also virtues like honesty, compassion, or a naïve expectation of good faith on the part of the con artist.

    Just as there is no typical profile for swindlers, neither is there one for their victims. Virtually anyone can fall prey to fraudulent crimes. Movie actors and athletes, professional persons and successful business executives, political leaders and internationally famous economists have all fallen victim to investment fraud. Certainly victims of high-yield investment frauds may possess a level of greed which exceeds their caution as well as a willingness to believe what they want to believe. However, not all fraud victims are greedy, risk-taking, self-deceptive individuals looking to make a quick dollar. Nor are all fraud victims naive, uneducated, or elderly.

Confidence tricksters often rely on the greed and dishonesty of the mark, who may attempt to out-cheat the con artist, only to discover that he or she has been manipulated into losing from the very beginning. This is such a general principle in confidence tricks that there is a saying among con men that "you can't cheat an honest man."

However, some tricks depend on the honesty of the victim. In a common scam, as part of an apparently legitimate transaction, the victim is sent a worthless check, which the victim then deposits. The victim is then urged to forward the apparent value of the check to the trickster as cash, possibly keeping a small portion of the money as a commission, which they may do before discovering the check bounces. Another fashionable scenario (as of 2006) has the victim recruited as a "financial agent" to collect "business debts". Paper checks are not always involved: funds may be transferred electronically from another victim.

Sometimes con men rely on naive individuals who put their confidence in get-rich-quick schemes, such as "too good to be true" investments. It may take years for the wider community to discover that such investment schemes are bogus, and usually it is too late, as many people have lost their life savings to something in which they have been convinced to invest.

The confidence trickster, con man, swindler, grifter, scam artist or con artist often works with one or more accomplices called shills, who help manipulate the mark into the con man's trick or dishonest plan. In a traditional confidence trick, the mark is led to believe that he will be able to win money or some other prize by doing some task. The accomplices may pretend to be random strangers who have won and benefited from successfully performing the task.
