The psychology of psychopathy: An inside look at the psychopathic brain A 2017 University of Wisconsin-Madison study was the first of it's kind to show structural differences in the psychopathic brain. JAIMEE BELL 23 June, 2020
According to a 2017 study led by the University of Wisconsin-Madison, psychopaths have reduced connections in the areas of the brain that control fear, anxiety, empathy and sentimentality. Psychopathy is typically diagnosed using a 20-item checklist called the Hare Psychopathy Checklist. Psychopathic tendencies could be considered "warning signs" of psychopathy, but it's important to note that not everyone who shows psychopathic tendencies becomes a psychopath. Psychopathy is defined as a condition (sometimes referred to as a personality disorder) characterized by the absence of empathy and the bluntness of other affective states. Psychopaths can be highly manipulative, often coming across as typical or even charming.
According to Psychology Today, callousness, detachment and a lack of empathy are key traits of a psychopath, but underneath the facade, they lack any semblance of a conscience.
