研究發現，與駕駛標有其他飲料logo汽車的實驗者相比，駕駛紅牛車的實驗者要更勇猛。

Companies spend billions on advertising every year. But they're not just pushing products—they're selling their brand's "personality," too. Think: Red Bull. What comes to mind? Most people say things like speed...power...hyper...extreme.

Well, a pair of scientists wanted to see if the energy drink's alleged qualities would influence people's performance in a racecar video game—without sipping Red Bull. So they had 70 volunteers race cars with identical specs, but different paint jobs. Four with the logo and colors of a drink—Guinness, Tropicana, Coca-Coca or Red Bull—and one car just plain green.

The drivers clocked similar times with most of the cars. But behind the wheel of the Red Bull car, they actually drove more aggressively, scoring either incredibly fast race times, or their slowest—by driving recklessly and crashing. The study appears in the Journal of Consumer Psychology. [S. Adam Brasel and James Gips, "Red Bull “Gives You Wings” for better or worse: A double-edged impact of brand exposure on consumer performance"]

Polled after the game, the players didn't realize the Red Bull image apparently influenced their driving. Which suggests marketing doesn't just influence a brand’s personality. It could be shaping our personalities, too, without our even knowing it.
