“Wilby had a problem. He didn’t know which brand of toothpaste to buy. He decided to try this new opposing viewpoints idea he’d been reading about in The Fallacy Detective. He decided to go around and ask different people what they thought. Wendy, a store assistant who offered to help: This type with oxy-white pro is guaranteed to make your teeth whiter in twenty-four hours. (Wilby noticed that toothpaste brands with the oxy-white pro sticker were twice the price of other brands.) Phoebe, a friend of Wilby’s: Wilby, I think you’d have such a cute smile if you got rid of some of those blueberry Popsicle stains on your teeth. Judd, another friend: Toothpaste? What’s that? Real men don’t brush their teeth. Wilby’s Mom: Wilby, it really doesn’t matter, as long as you don’t buy anything that contains fluoride additives. You might come down with a terrible disease in a few years if you use fluoride. Austin, Wilby’s coworker: I only use Hug-A-Tree brand. It’s made by an environmentally conscious company from Denmark. They promise they don’t test their product on whales. Bob, who works out at the health club with Wilby: I heard on a talk show that if you chew organic mint leaves, then your breath will smell good without having to brush your teeth. Wilby concluded that he was worrying too much over nothing. He decided to keep using the brand of toothpaste he’d always used. It seemed to do the job. But now he understood more about how different people make their decisions.”
