The fallacies are noted in brackets throughout the text:
Food For Thought
“Let’s hit the produce section first,” Curtis says to his fiancée Talia, as they enter Payless
grocery store.
“Okay,” she says.
“Oh, look,” says Curtis. “The corn is on sale. Let’s buy a couple of ears and cook them
for dinner.”
“I don’t know,” says Talia. “Did you see that sign over the display? The corn is
genetically modified. I know we’ve never paid much attention to that sign in the past, but now
I’m thinking that maybe we should.”
“Why’s that?” asks Curtis.
“Sounds like a great way to grow corn,” Curtis says.
“Yes,” replies Talia, “but that means the corn contains a residue of Roundup. That’s
definitely not good. Roundup is a probable cause of cancer.”
“Good grief,” says Curtis. “If what you say is right, I think there is only one conclusion:
We must ban the sale of Roundup immediately.” [Missing the point]
After pausing to scratch his head, he continues, “On the other hand, look at all the people
who are buying this corn. If everyone is buying it, then I think we should, too.” [Appeal to the
people]
“You’re right that everyone is buying it,” says Talia. “Nearly 90 percent of the corn sold
in this country is genetically modified. But that doesn’t mean that we should buy it. Look,
there’s a small display of organic corn over there. Let’s get some of that.”
“Well, maybe I could eat conventional restaurant food once in a while,” says Talia. “But
organic food has become really appealing these days. That actor Christian Slater promotes it in
magazine ads. And some of my friends say that he is really sexy and that you look like him!
Maybe you should think about switching to organic.” [Appeal to vanity]
“I look like Christian Slater?” asks Curtis, looking flattered. “Wow! Maybe you’re right.
But now that you’ve raised the issue, that reminds me of something. Didn’t you tell me a while
back that you had an uncle who grew organic food? If he makes a lot of money, you might
