Portuguese research suggests possible link between gut bacteria and psychopathy

There appears to be a link between psychopathic traits and bacteria in the gut and mouth. This is suggested by Portuguese research in which participants were tested for psychopathic traits and their bacteria were analysed. However, the results are preliminary.

According to the researchers, the composition of the microbiome may play a role in personality traits. However, they emphasise that the research does not prove a causal link. It is not yet clear whether the link is direct or via other factors.

The research was published by Portugal Resident, a local news site in the country. The research results need to be confirmed by larger studies before conclusions can be drawn.
