In Friday's Style Plus consumer quiz, the correct response for Question 11, $116,000, did not appear in the list of possible answers. (Published 10/2/90)

Texas Agriculture Commissioner Jim Hightower once was told a former governor was taking Spanish lessons. "Oh good," said Hightower. "Then he'll be bi-ignorant."

So's the American consumer. Buy-ignorant, that is.

According to a survey of 1,139 people released this week by the Consumer Federation of America (CFA), the majority of folks have limited practical knowledge about such everyday items as mortgages, automobiles, insurance policies, service contracts, unit pricing on food, and saturated versus polyunsaturated fats. The average score was 54 percent; in none of the six general subject areas did consumers score as high as 60 percent. Since all the questions were multiple choice, it was possible to score 25 percent just by guessing.

"It's hard to give an overall grade," says CFA executive director Stephen Brobeck. "I would call it passing -- but just barely. There's much room for improvement."

Barely a third of the respondents understood, for instance, that the annual percentage rate (APR) is the best indicator of what a loan will actually cost, and less than one in five knew what used car dealers are required to disclose.

But the picture isn't completely bleak. "Consumers appear to know a great deal about a number of important subjects," Brobeck says. "We were heartened, for example, to learn that 87 percent of respondents understand the significance of cosigning a loan. That's one of the greatest pitfalls in the area of consumer credit -- that the cosigner is as obligated as the borrower to repay that debt."

Drugs are another area where scores were relatively high. Sixty-one percent of respondents, for instance, are aware of the possible dangers in routinely giving aspirin to a child with the flu, while more than three-quarters understand what generic drugs are and their price advantage.

Brobeck gives the credit here to advertising. "Clearly," he says, "advertising appears to have an impact, and represents a potential means of communicating essential information to consumers." He hastily adds, however, that CFA still considers most consumer advertising inferior.

From the highest to the lowest: "There is widespread ignorance about how to buy a house efficiently," the report states. Only a third of the quiz-takers knew that a real estate agency represents only the seller. "I would have thought it would have been double," says Brobeck. "I was shocked at that finding."

For related questions, like the meaning of a point, the approximate interest charge on a typical mortgage loan and the purpose of title insurance, the percentage answering correctly drops even more -- to a level quite a bit lower than the percentage of home-owning adults.

While there were few differences in scores between men and women, the other breakdowns are about what you would expect: the more education you have and the more money you make, the better you did. And while those aged 30 to 59 all scored roughly the same (between 57 and 59 percent), the 60-plus group took a tumble: 52 percent.

The touching -- and misplaced -- tendency of older people to trust what companies, advertising and product labels tell them was explored more fully in an American Association of Retired Persons survey released in June.

For example, while nearly two-thirds of those under 65 said they believed businesses attempted to mislead consumers at least half the time, only 44 percent of the 65-plus group felt this way. Similarly, nearly half the older respondents did not know that it was illegal to deny someone credit because of their age.

"Older consumers' buying habits were formed during a time when a more trusting relationship existed between the sellers and buyers of goods and services," concluded AARP executive director Horace Deets. "To this extent, older consumers are at a disadvantage in dealing with some of today's business practices."

A Telling Quiz ...

The following 25 questions are drawn from 250 developed by a team of experts for the Consumer Federation of America. The Educational Testing Service then refined those multiple choice queries into five exams containing 50 questions each. The quizzes were administered at five shopping malls at various locations around the country. Demographically, the respondents approximated the U.S. population.

The average test-taker got 54 percent of the questions correct. The queries below are a bit tougher: respondents got them right only 44 percent of the time.
