The Impact of Comparative Product Testing
upon Consumers. Selected Findings of a
Research Project
ABSTRACT. The paper presents some of the main results of a research project dealing with
consumer product testing in the Federal Republic of Germany. They concern the use and
impact of product test information among consumers (effects on industry and trade are
dealt with in a companion paper, Raffee & Fritz, 1984). The analysis is based on the as-
sumption that the consumer product test has to accomplish a broad set of tasks. On the
basis of these tasks and the different empirical results some propositions for the policy of
product test institutions are formulated.
In the past, several research studies have dealt with the comparative
consumer product test (e.g., Kaas & Tolle, 1981; Silberer, 1979b;
Thorelli, Becker, & Engledow, 1975; Thorelli & Thorelli, 1974;
Tolle, 1983). The project to be reported here concerned the use and
the effects of product test information emanating from the German
testing institution Stiftung Warentest upon industry, retailers, and
consumers. The purpose was to provide a basis for recommendations
concerning the future policy of product test institutions.
This paper reports the results of our studies in the consumer
sphere. Only selected results and recommendations can be presented
here; a more detailed report can be found in Silberer and Raffee
(1984b). The results of our studies in industry and retailing are
published separately, both in this journal and elsewhere (Fritz,
1984; Raffee & Fritz, 1984; Raffee & Silberer, 1984).
THE TASKS OF CONSUMER PRODUCT TESTING. A NORMATIVE FRAME OF
REFERENCE
The main purpose of our research was to analyze relevant effects of
comparative product test information upon the buying decisions
of consumers who use such test information. This required a delinea-
tion of the tasks or goals of consumer product tests. In so doing, we
had to keep in mind that the tests are carried out by an institution,
Stiftung Warentest, which receives subsidies from the Federal Govern-
ment (Silberer, 1979a).
