Created a virtual lie detector - the Internet will become more honest?

Perhaps in the future the Internet will be cleared offraudsters, and the users themselves will have to carefully monitor their words. Researchers at the University of Florida have developed an artificial intelligence that perfectly performs the role of a polygraph and reveals a lie, following the words sent by the user and the speed of their typing. The test results showed that he was already able to discern the truth from lies in 85% of cases, while the accuracy of real lie detectors varies only in the region of 60-70%.

To train the system to separate the truth fromwrong, the developers have resorted to machine learning. A group of forty volunteers were asked to play an online game in which they were randomly assigned the role of a “saint” or a “sinner”. For 80 game sessions, they answered questions, and artificial intelligence carefully followed their messages.

It turned out that "saints" or "sinners" usecompletely different sets of words and type them at different speeds. For example, liars often use the words "always" and "never" to emphasize their confidence, and respond very quickly. People who speak the truth often use the word "possibly" and type words more thoughtfully and, accordingly, slowly.

As a result, paying attention to the frequency of words andspeed of response, the online polygraph has learned to recognize the lie with an accuracy of 85 to 100%. Researchers recognize that too few people took part in the test, but even now it is clear that the technology has great potential. They intend to improve it and contact the developers of various instant messengers to popularize their brainchild.

This baseline study showed a largethe potential of developing an online printing system to improve communication on the Web. I want to attract the attention of the whole world to this idea, so that we could turn it into a commercial product that could be introduced into instant messengers.
