[Is David Lykken's theory of crime likely? ]. 
Lykken proposed a model of antisocial behaviour based on the criminal's temperamental difficulties.  Personality traits stressed by this model are impulsivity, fearlessness, and sensation seeking.  The present study compares one sample taken from the general population with a sample of prison inmates on these traits.  The results indicate that prison inmates score higher than the general population on sensation seeking and fearlessness, whereas their scores on impulsivity are lower.  Some implications are discussed.
