I'd be interested in any kind of study that demonstrated that rigorously, but I'm pretty skeptical by default. Most consumer brands I can think of are completely meaningless taken on their own, and to the extent they mean anything, it's not even the right thing. What does a "Wal" Mart sell? What do I buy at a "McDonald's"? IKEA?! Is "Siemens" a German condom company? Is a "Safeway" a shelter for victims of violence?
