One stereotype of people with tattoos is that they are more aggressive and rebellious than people without tattoos. However, studies examining differences in these traits between tattooed and non-tattooed individuals are dated and have returned equivocal results. To re-examine this issue, we asked 378 adults from London, UK, to complete self-report measures of aggression and rebelliousness, and to report the number of tattoos they possessed. Of this sample, 25.7% possessed at least one tattoo, with no sex difference in the distribution of tattoo status. We found that tattooed adults had significantly higher reactive rebelliousness, anger, and verbal aggression than non-tattooed adults. However, effect sizes were small and there were also no significant between-group differences in terms of proactive rebelliousness, physical aggression, and hostility. These results suggest that, while stereotypes may contain a kernel of truth, they likely present an outmoded picture of tattooed adults.
