Results of two survey studies (N = 197 and N = 2037) are presented. It is shown that attitudes of the public about "technology in general" are not stable and can easily be affected by how the subject is introduced. Eight areas of technology are compared on the basis of empirical relations in attitudinal judgments, in attribute ratings, in selfassigned importance weights of attributes, and in importance of reference groups and persons. On the basis of similarities in these four kinds of judgments, three clusters of technology areas were identified: (1) a cluster of modern reproductive technologies, (2) an information cluster containing automation, computer, and communication technologies, and (3) a cluster containing nuclear energy and military technology. The attitude toward "technology in general" can not be considered as an aggregation of attitudes toward these areas of technology: The relations between general attitude and specific attitudes are only moderate to negligible. Experts and entrepreneurs are as a matter of course involved with the development and implementation of technological innovations. The government, too, is a party with direct influence, for instance as subsidizer, regulator, and consumer. The role of citizens is indirect: Via Parliament and as selective consumers they can exercise some influence on technological developments. In recent decades, segments of the population have found that they cannot adequately influence technological developments through this indirect route. More directly, via pressure groups, they have agitated against the implementation of certain technological innovations. A well-known example is the movement against nuclear energy. Resistance of this kind can at least slow down the implementation of technologies and affect (in the eyes of some) the economic competitiveness of the country. &dquo;Public acceptance&dquo; therefore has become an important topic for entrepreneurs and politicians when decisions about future technologies are at stake.
