Theoretical and empirical problems in the assessment of alternative medical technologies.

Critical situations help to clarify and define otherwise indistinct and vague phenomena. The paradigm-collision which occurs when assessing alternative medical phenomena against the background of a medical school paradigm is analogous to a critical situation. An analysis of the conditions for such an appraisal has helped to highlight aspects which are not normally ascribed any great significance in the assessment of technology. It turns out that theoretical requirements, the specific concept and certain irrational elements play a large role in the assessment of medical and alternative medical technology. One conclusion is that in the appraisal of e.g. alternative medical technology, one must take into account these conditions for forming a judgement, as a basic requirement for an objective appraisal of the technology in question.
