Are tattooed adults really more aggressive and rebellious than those without tattoos?

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.
