Researchers claim they have found a new test which by just measuring heart rate can determine whether a person is predisposed to any antisocial or criminal behavior. The findings of the study were published on Wednesday in the journal JAMA Psychiatry.

Scientists said all one needs is a clock and two fingers. The test just measures your resting heart rate, they said. During the test if a person’s heart beat counts fewer than 60 beats per minute, one might be physiologically predisposed to commit robbery, assault, kidnapping or even murder, new research suggests.

Studies from more than dozen countries have found that people with slow-beating heats are more likely to behave in antisocial ways. However, most of these studies involved small number of people and they were not tracked for long period of time.

Researchers from the Karolinska Institute near Stockholm thought they could do a better study by improving both the key points by examining decades of data collected by the Swedish government.

Until 2009, nearly all Swedish men were required to undergo a ‘conscription assessment’ for the armed forces when they turned 18. These records included data on heart rate testing of nearly 710,264 people.

The study researchers referred the Sweden’s crime register to see whether any of those people had been convicted of a violent or nonviolent offense after their heart rate was measured. They also examined the medical records to check whether the men had been injured or killed in an assault or accident.

They found that the men with the lowest resting heart rates at age 18 were most likely to commit crimes as they got older.
