Khaberni - German researchers at the University of Bamberg have uncovered four recurring psychological traits that can be observed in sexually motivated serial killers, after analyzing data and statements from 45 offenders active over six decades.
The team relied on the Radford/FGCU database, which includes over 1,043 cases, before selecting offenders who acted alone and were legally competent at trial.
The study showed that these four traits often do not appear independently, but overlap to reflect a complex mix of psychology and behavior:
-
Grandiose Competitiveness:
Observed in 32 cases, this trait refers to a relentless pursuit to assert dominance and devalue others, reflecting an inner need for control and self-affirmation.
-
Grandiose Admiration:
Recorded in 34 cases, it expresses an impetus toward self-promotion and a continuous pursuit of external admiration to ensure a sense of importance.
-
Paranoid Aggression:
Noted in 38 cases, it includes a feeling of persecution and suspicion, which leads its bearer to interpret situations as personal threats.
-
Weakened Isolation:
Featured in 26 cases, it relates to social withdrawal to protect fragile self-esteem, along with excessive sensitivity towards rejection.
The researchers emphasized that the presence of these traits does not conclusively indicate a tendency towards violence, but they aid in a better understanding of the complex psychological patterns that may interact within this type of offender.
The study concluded that sexual violence often thrives on a delicate balance between a sense of superiority and inner fragility, explaining the complexity of behavior and the specificity of motivations in each case.
