Females who have excessively male characteristics may be more biologically predisposed to crimes, according to Cesare Lombroso (Siegel and Welsh 251). The masculinity hypothesis asserts that women who look more like men, by having excessive body hair and wrinkles and abnormally-sized cranium, tend to be more aggressive than women who do not have these characteristics (Siegel and Welsh 251). Genetics may also explain why some girls are predisposed to crime (Roberson 49). Having certain genetic traits might increase aggression and poor risky behaviors (Roberson 49). Biological reasons assert that the biology of female delinquents can help explain their inclination to crimes.
Besides biological explanations, psychological reasons underscore that psychological mechanisms underlie rising female juvenile crime rates. Girls who are involved in larceny may have a stronger id than superego (Roberson 49). They gain immediate gratification from shoplifting, for instance (Roberson 49). In addition, the psychoanalytical approach underscores that traumatic childhood experiences prevent girls from developing their egos and superegos properly (Roberson 49). Female juveniles are often victims of physical and/or sexual abuse while very young (Lawrence and Hesse 61). These abuses damage them psychologically, with some experiencing mental and emotional illnesses, which make them susceptible to poor risk assessment, impulsivity, and desire for immediate pleasures to relieve their anxieties (Siegel and Welsh 254).
Sociological theories differ on the reasons that they believe may be causing the rise in female juvenile crimes though they agree that social changes and factors shape the latter. A poor home environment may have more significant damage on girls than boys (Siegel and Welsh 257). Many girls are running away and are involved in simple
