If you’re trying not to go overboard with the holiday shopping this year, you might want to stay out of the men’s department. A study published in the Journal of Consumer Psychology found that women who touched boxer shorts were more likely to spend more money. The study was geared towards understanding how sexual cues impact shopping habits. The results were the women shoppers spent more than they needed to after handling male underwear on items including chocolate, a chair and a keyboard, throwing price tag caution to the wind. Scientists believe this may be because the boxer shorts triggered the reward center in the brain, which makes people more inclined to take risks for immediate pleasure. In this case, the risks were financial. So, when you’re finishing up your Christmas purchases save those silk boxer short stocking stuffers for last before you leave the store.
