    The crocodile’s tears
    (University of Lethbridge, 2006) Lalumière, Martin L.
    People are fascinated by criminals, especially clever criminals who have the ability to con others. The most vicious offenders are often the subjects of movies and true-crime books. Canadian Paul Bernardo, for example, kidnapped, raped, killed, and mutilated two teenage girls, was involved in the rape and death of his sister-in-law, and raped dozens of women in the late 1980's and early 1990's. His story has already been written in several books, and a movie about him and his wife was released in the spring of 2006. During his trial he received numerous love letters and marriage proposals from complete strangers. Famous criminals are often the inspiration for great literature. Robert Louis Stevenson, for example, is said to have based his story of Jekyll and Hyde on William Brodie. Brodie was a well-respected Deacon by day and a gambler, womanizer, and burglar by night. Our ready fascination for these offenders demands an explanation, but in this chapter I will focus on discussing a group of men who are often considered to be the worst criminals, psychopaths. I begin by describing the concept of psychopathy and showing how unique psychopaths are. Then I discuss the question of whether psychopathy is a mental disorder, and describe an alternative view of psychopathy.

    Nepotistic patterns of violent psychopathy: evidence for adaptation?
    (Frontiers Research Foundation, 2012) Krupp, Daniel Brian; Sewall, Lindsay A.; Lalumière, Martin L.; Sheriff, Craig; Harris, Grant T.
    Psychopaths routinely disregard social norms by engaging in selfish, antisocial, often violent behavior. Commonly characterized as mentally disordered, recent evidence suggests that psychopaths are executing a well-functioning, if unscrupulous strategy that historically increased reproductive success at the expense of others. Natural selection ought to have favored strategies that spared close kin from harm, however, because actions affecting the fitness of genetic relatives contribute to an individual’s inclusive fitness. Conversely, there is evidence that mental disorders can disrupt psychological mechanisms designed to protect relatives. Thus, mental disorder and adaptation accounts of psychopathy generate opposing hypotheses: psychopathy should be associated with an increase in the victimization of kin in the former account but not in the latter. Contrary to the mental disorder hypothesis,we showhere in a sample of 289 violent offenders that variation in psychopathy predicts a decrease in the genetic relatedness of victims to offenders; that is, psychopathy predicts an increased likelihood of harming non-relatives. Because nepotistic inhibition in violence may be caused by dispersal or kin discrimination, we examined the effects of psychopathy on (1) the dispersal of offenders and their kin and (2) sexual assault frequency (as a window on kin discrimination). Although psychopathy was negatively associated with coresidence with kin and positively associated with the commission of sexual assault, it remained negatively associated with the genetic relatedness of victims to offenders after removing cases of offenders who had coresided with kin and cases of sexual assault from the analyses.These results stand in contrast to models positing psychopathy as a pathology, and provide support for the hypothesis that psychopathy reflects an evolutionary strategy largely favoring the exploitation of non-relatives.
