8. Wrong application of idea that the theory should be considered as true, only if it is proved

 If to consider scientific method, as a way of reception of the most authentic knowledge this methodology is true. However from the point of view of safety maintenance the opposite approach is necessary: a certain assumption should be considered dangerous until it is not denied. For example, the new model of the plane is considered dangerous, until then will not be proved yet, by theoretical calculations and test flights in all modes, that it is safe; the same principle underlies clinical testing of new medicines. Not clearly the same as to apply a principle falsification concerning theories about those or other global catastrophes.
