The incident of Scanzano Jonico, in Italy's Basilicata region, has been something more than a lesson for those who handle the relationships between science and society. During November and December 2003 in this small southern Italian town a theory has been proven false. According to this theory, in the modern world, the best way to solve the problems put before society by science and technology would be for the experts to discuss them behind closed doors.

In the midst of a debate on access to information, the World Health Organization and the FAO have decided to develop a strategy to guarantee the right of poor countries to have free access to scientific publications. This right is often denied, mainly because of high subscription costs. For this reason, universities and research centres in southern countries must forego buying magazines, which are a valuable instrument for updating, and exchanging information on research and scientific issues. This choice has been made in an historical period when the industrialized world is marked by a knowledge-based economy.

A ghost is wandering around the web: it is called open access, a proposal to modify the circulation system of scientific information which has landed on the sacred soil of scientific literature. The circulation system of scientific magazines has recently started faltering, not because this instrument is no longer a guarantee of quality, but rather for economic reasons. In countries such as Great Britain, as shown in the following chart, the past twenty years have seen a dramatic increase in subscription fees, exceeding by far the prices of other publishing products and the average inflation rate. The same trend applies to the United States.

On June, the 23rd of last year, the US Environmental Protection Agency (EPA) published its Draft Report on the Environment, a report on environmental quality. The EPA is an autonomous federal agency known for its reliability on environmental studies and safeguards. Its Draft Report is considered by Science, the journal of the American Association for the Advancement of Science (AAAS), the nation's most scientifically reliable analysis on environmental quality.

Scholars and scientists do research to create new knowledge so that other scholars and scientists can use it to create still more new knowledge and to apply it to improving people's lives. They are paid to do research, but not to report their research: that they do for free, because it is not royalty-revenue from their research papers but their "research impact" that pays their salaries, funds their further research, earns them prestige and prizes, etc. "Research impact" means how much of a contribution your research makes to further research: do other researchers read, use, cite, and apply your findings? The more they do, the higher your research impact. One way to measure this is by counting how many researchers use and cite your work in their own research papers.

This article will discuss and comment some of the results obtained by the application of the questionnaire "Public perception of Science and Technology". The questionnaire is a translated and adapted Portuguese version from the original in
