People with visible tattoos are more likely to act more impulsively and recklessly than their non-inked counterparts, according to a study of more than 1,000 people conducted in Canada.

A group of economists conducted the survey in the hopes of finding out why tattoos have become so popular — even as employers and society at large tend to discriminate against people who are tatted up, the Times of London reported.

The survey quizzed 781 people without tattoos and 255 with tattoos, including 68 people whose ink is visible while they’re fully clothed.

During the survey, which was published by the Journal of Economic Behavior and Organization, the economists included a monetary test that would offer a greater payday for the contestant, if they waited longer to cash out.

Non-tattooed participants realized earlier in the game the exact strategy they should use to earn the most money, according to the Times.

The study also found that tattooed participants answered a simple logic question impulsively.

A Canadian economist told the newspaper he hopes the findings will make people think twice about getting ink, but added the traits found in people with tattoos are not always a bad thing.

“Sometimes it’s good to make decisions fast. If you’re a professional basketball player and you need to decide whether to shoot or pass, you don’t want someone who stands there and deliberates,” professor Bradley Ruffle said.
