A team of scientists at the University of Porto says it has found a "measurable biological footprint" connecting specific gut and oral bacteria to psychopathic personality traits, a finding that, if confirmed, could reshape how researchers understand antisocial behavior. The study, led by researcher Carolina Costa and published in Nature , enrolled 200 healthy adults and asked them to complete a standardized psychopathy questionnaire known as the Self-Report Psychopathy Scale-Short Form.

What the researchers found was specific and striking: three types of gut bacteria, Allisonella, Prevotella, and…Open
