Leading a group of Swedish scientists including Matthew B. Carter M. D. PhD of St Olmo Health Research Center in Stockholm has published a paper in the New England Journal of Medicine that describes the development of personality profiles from routine computerised medical assessments. Psychopathy is a personality disorder a person who stems from a defect in ones general disposition to seek pleasure in harming other people.

Traditionally there has been a gap separating diagnosing and classified mental disorders.

Psychopathy a type of antisocial personality disorder is characterised by a marked increase in the number of ways individuals betray their own values and intentions in behavior often resulting in antisocial behavior use of coercion and violation of obligations the paper explains. Most features of the disorder manifest themselves in a trait (such as fixation on sex) including all sexual and aggressive behaviors.

The researchers found that small changes in the person carrying out tests for psychopathic traits such as increased aggressiveness could be used to categorize psychopathy.

In an earlier study we found that it was possible to change the way personality profiles could (. . . )be grouped using changes in the initial number of traits rather than by an arbitrary method of grouping the paper said. Now for the first time we have been able to split personality disorders by applying new personality classification methods using a new number of biases called the Penguin-Spatter classifier.

Busting biases using new research methods.

We also found that the Penguin-Spatter classifier can reliably infer the personality traits and deviances of a patient based on the clinicians upcoming assessment also explained Matthew B. Carter one of the authors.
