A pair of researchers recently put the “socio” back into in socio-economically disadvantaged. The study is the first to identify a specific gene associated with psychopathic traits in youth, a gene related to variances in how serotonin is processed in the brain. The twist is that this gene only seems to produce psychopathic traits in those children from low-socioeconomic backgrounds.
The researchers focused on sociopathic traits, rather than diagnosing the youths. The characteristics they were looking for include: “tend to be less attached to others, even if they have relationships with them. They are less reactive to emotional things in the lab. They are charming and grandiose at times. They’re better at conning and manipulating others, and they have low levels of empathy and remorse. For example, these folks tend to have less anxiety and are less prone to depression, qualities that might be useful in dangerous or unstable environments. In most cases, their cognitive abilities are also intact.”
The research showed that kids with one variety of a serotonin transporter gene are more likely to show psychopathic traits if they are also raised in a lower socio-economic environment. (Previous studies have shown that people with psychopathic traits typically have more brain serotonin than their peers.)

These children reportedly exhibited less empathy, they were more prone to arrogance and deceitfulness and were less emotionally responsive to negative events than their peers. In contrast, youth with the [same gene] who also had high socioeconomic status scored very low on psychopathic traits suggesting that the long allele is susceptible to socioeconomic environment, for better or for worse.Yet another reason to be nervous when your car breaks down in a bad neighborhood.
