Abstract
Legal controls over data collection in European countries have badly affected the work of epidemiologists. By contrast, journalists have been allowed far greater freedoms. The aims and tasks of both professions are in line with accepted values in our society--especially those of inquiry and the benefits of an open society. Society seems willing to accept that, in the interests of wider public good, journalism may sometimes invade individuals' privacy and do them harm, but it is not prepared to offer epidemiology an equal measure of tolerance.
