“Given that we suffer so much fake news and disinformation spreading, there is a benefit to these technologies.”<\/em>

Image by standret<\/a> on Freepik<\/h4>\n\n\n\nA polygraph test ostensibly measures a person’s breathing rate, pulse, blood pressure, and perspiration to figure out if they’re lying or not \u2014 though the 85-year-old technology has long been debunked<\/a> by scientists. Basically, the possibility of false positives and the subjectiveness involved in interpreting results greatly undermines the usefulness of the polygraph as a lie detector. Tellingly, their results are generally not admissible in US courts<\/a>

\n\n\n\n

Because it’s 2024, researchers are now asking whether artificial intelligence might help. In a new study<\/a> published in the journal iScience<\/em>, a team led by University of W\u00fcrzburg economist Alicia von Schenk found that yes, it just might \u2014 but, as MIT Tech Review<\/em> reports<\/a>, it also led to experimental subjects making more accusations overall, in yet another warning about the far-flung risks of replacing human intuition with algorithms.<\/p>\n\n\n\n

First, the researchers asked participants to write down statements about their weekend plans. If they successfully lied about their plans without being found out, they were given a small financial reward.<\/p>\n\n\n\n

The collected statements were then used to train an algorithm based on Google’s large language model BERT. The scientists found that it was capable of telling if a given statement was a lie with a success rate of 67 percent, a significant improvement over humans, who tend to only get it right 50 percent of the time.<\/p>\n\n\n\n

Von Schenk and her colleagues then offered a separate group of volunteers the option to use the algorithm for a small fee to detect lies or rely on their own human intuition.<\/p>\n\n\n\n

Only a third of the volunteers were willing to use the tool \u2014 but they also became power users.
