Confidence trick

A confidence trick, confidence game, or con for short (also known as a scam) is an attempt to intentionally mislead a person or persons (known as the mark) usually with the goal of financial or other gain. The confidence trickster, con man, scam artist or con artist often works with an accomplice called the shill, who tries to encourage the mark by pretending to believe the trickster. In a traditional con, the mark is encouraged to believe that they will obtain money dishonestly by cheating a third party, and is stunned to find that due to what appears to be an error in pulling off the scam they are the one who loses money; in more general use, the term con is used for any fraud in which the victim is tricked into losing money by false promises of gain.

Extra finesse

Many con men employ extra tricks to keep the victim from going to the police:

• Illegal money. A common ploy of investment scammers is to encourage the victim to use money that has been concealed from the tax authorities. The victim cannot go to the authorities without revealing that they have committed tax fraud.
• Illegal enterprise. Many swindles involve a minor element of crime or some other misdeed. The victim is made to think that they will gain money by helping fraudsters get huge sums out of a country (the classic Nigerian scam). The victim cannot go to the police without revealing that they planned to commit a crime themselves. Similar tricks can be played on people shopping for pirated software, illegal pornographic images, bootleg music, drugs, firearms or other forbidden or controlled goods.
• Embarrassing enterprise. If the victim loses a small sum only, they may be unwilling to contact the authorities if the circumstances are embarrassing, e.g. if they would look like an idiot or if their spouse would find out that they paid lots of money to access a website of (worthless or nonexisting) pornographic material.
