New York City police are calling for an increased use of polygraph testing, but the truth is that a small percentage of people who go through the tests actually pass.
“The testing is a very accurate tool,” said NYPD commissioner Raymond Kelly, who called for the testing in an interview with New York magazine.
“But a small number of people get the wrong results and it can be very frustrating and hard to deal with.”
So how do you know if you’re on the right track?
The New York Police Department, which runs the test, has made it easier for people to get answers by using software called QP.
QP is an open-source tool, and it allows anyone to submit their own test results, rather than the traditional paper polygraph.
The software lets police officers check to see how many false positives are detected and which of the false positives is the most relevant to a suspect’s guilt.
“It’s not like they’re going to send a polygraph to a couple of people and ask them to fill out some forms,” said Kelly.
“We can go into the system and ask the people who take it what they want to know.”
To get a better feel for how well QP works, we took our own polygraph, submitted it to QP and tested it for accuracy.
We used it to find out how the New York police test works and the best way to avoid a false positive.
