More and more people seem to have tattoos these days, but those who like to show them off may be telling you something about themselves. A new study finds folks with visible tattoos tend to be more impulsive and reckless than those without ink. Participants, both with and without tats, were surveyed for the study, with the survey featuring a monetary test that would reward people with more cash the longer they waited to get it. Those with visible tattoos were less likely to wait, with non-inked participants realizing early how to wait to earn the most money. Meanwhile, the study also found that those with ink were more likely to impulsively answer a simple logic question.
