Dr. Allen Hersh designs smells for businesses. He says that it doesn't take a whole lot of smell to affect you. Store owners can lure you to the candy aisle, even if you don't realize you're smelling candy. This idea scares a lot of people. Groups that protect the rights of shoppers are upset. They say the stores are using a kind of brainwashing which they call "smell-washing". "It's pretty dishonest," says Mark Silbergeld. He runs an organization that checks out products for consumers. The scientists hired to design the scents disagree. "There's soft background music. There's special lighting. There're all sorts of bells being used," says Dr. Hersh, "why not smells?" "One reason why not," says Silbergeld, "is that some people are allergic to certain scents pumped into products or stores."
