According to Pustilnik, neuroscience research demonstrating that a psychopath is merely a victim of his own faulty biology cannot be used in court as an argument for his innocence. It is admissible, however, as evidence that a jury should be lenient during sentencing.
"When we're trying to figure out 'how blameworthy is this person?', I can imagine that a serial killer could use this finding at sentencing to argue that he was not morally blameworthy, but rather the puppet of his biology," she said."As in, 'the neuron firing pattern makes me do this.'"
To be used as such, though, the result of the case study would need to be generalized across a much larger set of cases to determine whether its finding is significant, or merely a chance correlation, Pustilnik said.
