Technology assessment assumes a global perspective and is future-oriented, not anti-technological. TA considers its task as an interdisciplinary approach to solving already existing problems and preventing potential damage caused by the uncritical application and the commercialization of new technologies.
Therefore, any results of technology assessment studies must be published, and particular consideration must be given to communication with political decision-makers.
An important problem concerning technology assessment is the so-called Collingridge dilemma: on the one hand, impacts of new technologies cannot be easily predicted until the technology is extensively developed and widely used; on the other hand, control or change of a technology is difficult as soon as it is widely used. It emphasizes on the fact that technologies, in their early stage, are unpredictable with regards to their implications and rather tough to regulate or control once it has been widely accepted by the society. Shaping or directing this technology is the desired direction becomes difficult for the authorities at this period of time.
